1 Safety Regulations

1.1 Correct UseThe S5000 Gas Monitor, hereafter also called device, is a gas monitor for measuring toxic and combustible gases as well as oxygen. Using sensors, the device tests the ambient air and triggers the alarm as soon as the gas exceeds a specific concentration level.

WARNING!

Do not use silicone-type lubricants in assembling the device and do not allow silicone vapors to be drawn into the flow system while in operation. Silicone can desensitize the combustible gas sensor, thereby giving erroneously low readings. Use only genuine MSA replacement parts when performing any maintenance procedures provided in this manual. Failure to do so may seriously impair sensor and gas monitoring performance, alter flameproof/explosionproof characteristics or void agency approvals.

Failure to follow these warnings can result in serious personal injury or death

WARNING!

As with all gas monitors of this type, high levels of, or long exposure to, certain compounds in the tested atmosphere could contaminate the sensors. In atmospheres where an S5000 Gas Monitor may be exposed to such materials, calibration must be performed frequently for dependable operation and to confirm that display indications are accurate.

These effects include, but are not limited to:

  • Passive MOS sensors may be adversely affected by prolonged exposure to certain substances. Loss of sensitivity or corrosion may be gradual if such agents are present in low concentrations or it may be rapid at high concentrations. Examples of these substances are as follows:– Halides: compounds containing fluorine, chlorine, bromine and iodine– Heavy metals, e.g. tetraethyl lead– Caustic and Acidic liquids and vapors– Glycol
  • The H2S Digital Sensor may be adversely affected by the following substances:– Alcohols (methanol, ethanol, isopropanol)– Nitrogen dioxide (NO2)– Chlorine (Cl2)– Paint solvents (acetone, turpentine, toluene, mineral spirits, etc.)
  • The CO Digital Sensor may be adversely affected by the following substances:– Alcohols (methanol, ethanol, isopropanol)– Paint solvents (acetone, turpentine, toluene, mineral spirits, etc.)
  • The O2 Digital Sensor may be adversely affected by the following substances:– Long term exposure to low levels of Acetylene– Paint solvents (acetone, turpentine, toluene, mineral spirits, etc.) in high concentrations larger than 1000 ppm or prolonged exposure to lower concentrations
  • Prolonged exposure of the H2S Digital Sensor to humidity levels of 5% RH or lower will result in gas measurement readings of H2S that are greater than the actual gas concentration present.
  • It is not recommended to expose the O2, H2S and CO Digital Sensors to environments containing oxygen levels above 30% (v/v) or below 5% (v/v). The O2 sensor will operate at concentrations below 5% (v/v) but not for prolonged periods of time.

2 Description

2.1 Display

The S5000 utilizes a dot matrix LED display, capable of displaying four alphanumeric characters at a time. The display will scroll words that exceed four letters. Most of the messages scroll twice across the screen before moving onto next selection.

                                                                           Figure 1  S5000 Main DisplayIn addition to the red LED display, the S5000 uses six icons to indicate status. Green LED indicates power supply status. A yellow triangle and red bell indicate fault and warning or alarm conditions respectively. The Bluetooth® icon indicates that the Bluetooth® wireless technology is enabled on the device. Yellow “1” and “2” icon indicate which sensor gas reading isbeing displayed, or during configuration which sensor’s options are being accessed.

2.2 No Tool Interface

The S5000 does not require any tools or third party devices to change settings, reset alarms or perform any maintenance operation. The EZ touch button works through the glass and does not require opening the explosion proof enclosure. The EZ touch button works with bare fingers or with gloved hands, so long as the gloves are not black. See 4 Operation for moreinformation on navigating the menu with the EZ touch button.   Figure 2 InterfaceThe user menu can also be accessed using the round GM magnet on the General Monitors logo.

2.3 Bluetooth® Wireless Technology

The S5000 comes by default with Bluetooth communication. Using the X/S Connect App on an appropriate smart phone or tablet, users are able to interface with the S5000 menu options in a larger and more user friendly setting. The Bluetooth communication can interact with the device within a maximum transmission distance of 70 feet (21 m).

WARNING!

Bluetooth operation is dependent upon signal availability of the wireless service(s) necessary to maintain the communication link. Loss of wireless signal will prevent communication of alarms and other information to linked devices. Take appropriate precautions in the event a loss of wireless signal occurs.

Failure to follow this warning can result in serious personal injury or death.

If ordered with Bluetooth, the device will be shipped with Bluetooth enabled. See 4 Operation for instructions on disabling Bluetooth.If the device was not ordered with Bluetooth it cannot be upgraded.

The S5000 and user provided communication device will need to be paired. This requires both devices to be in range and for a pairing sequence inputting a 6 digit pairing code. The instructions will be displayed on both the S5000 and communication device.

There are communication devices capable of being used in classified areas. Please contact your MSArepresentative for additional information.

2.4 Dual Sensing

The S5000 supports two Digital Sensors, or one IR Sensor point IR detector and one Digital Sensor simultaneously with four wire connections. However, the device will only support one passive sensor, either combustible catalytic bead or metal oxide semiconductor (MOS) sensors, based on the ATO configuration. Passive catalytic bead uses three wires, passive MOS uses four wires.The S5000 Gas Monitor generates two independent analog outputs; one for each sensor connected to the transmitter. Theanalog output associated with Sensor 1 also has the digital HART (Highway Addressable Remote Transducer)communication superimposed on the analog signal. If two sensors are connected, the digital HART communication carriesinformation for both sensors.

2.5 Retrofit Installations

The S5000 has the conduit entries located in the exact same orientation and distance from the wall and the mounting holes for attaching to a wall are identical to the S4000 Series detectors. Users will be able to re-use the existing wiring for the remotely mounted sensors.

2.6 XCell Sensors Optimized for Fixed Gas Applications

XCell toxic and combustible catalytic bead sensors are developed and manufactured by MSA. Now optimized for fixed gas applications, the XCell sensor platform is available in the S5000 and provides multiple benefits, including a standard 3-year warranty on all XCell sensors. One important optimization for fixed gas was incorporating the GM catalytic bead into the XCell sensor.The XCell Oxygen sensor does not use lead, but rather a non-consuming reaction chemistry. The XCell Oxygen sensor is expected to last well over 3 years and can be safely stored on the shelf for at least 1 year without sensor performance degradation. Changes in barometric pressure across the range of 86 kPA – 108 kPA have a negligible effect on the operation of the sensor.

2.7 TruCal Sensing Technology for CO and H2S Electrochemical Sensors

Using patented pulse check technology and proprietary Adaptive Environmental Compensation (AEC) algorithms, all XCell sensors with TruCal verify operation by actively adjusting the sensor output for changes in sensitivity. Some XCell sensors with TruCal also include Diffusion Supervision, which monitors the sensor inlet for obstructions that could prevent gas fromreaching the sensor. Every six hours, an electrical pulse stimulates the XCell sensor similar to having actual calibration gas applied, providing a snapshot of the sensor’s sensitivity at the time of the pulse. Using this sensitivity snapshot, the sensor can diagnose sensor failures like electrode poisoning, electrolyte leaking, or electrical connectivity issues. AEC uses the sensitivity snapshots provided by the pulse check to adjust sensor output, compensating for environmental impacts on sensor accuracy. If the AEC adjustment is greater than expected based on typical environmental impact variations, the transmitter LED’s will slowly flash GREEN, alerting users that the sensor should be calibrated to reset the AEC cycle. Users can also enable a Calibration Alert function that will send a milli-amp signal on the analog output to the control room. The result is a sensor that actively self-monitors for operation and accuracy, with far fewer manualcalibrations. Diffusion supervision actively monitors the sensor inlet for obstructions. If an obstruction is detected, the sensor will go into a fault mode to alert users and the control room that it is not seeing gas due to an obstruction. Objects residing directly on or in the sensor inlet that result in a significant impact to the gas path are very likely to be detected by Diffusion Supervision. Examples include paint, tape, water, and dirt. Small amounts of these materials can be visible on the inlet while not impacting the gas path enough to trigger a Diffusion Supervision Fault. A fault signal will only be sent out when the system determines that the amount of material that has accumulated on or inside the sensor inlet is negatively affecting the gas path. Actual TruCal sensor performance will depend on the application, background gas exposure, and environment. To validate XCell sensors with TruCal, it is recommended that users follow their regular calibration cycle and record the “as found” and “as left” values. This data can be used to extend the time between calibrations depending on the required specification ofthe application.

2.8 SafeSwap

The S5000 comes with patented SafeSwap technology, which allows users to change or replace XCell sensors without needing to power down the instrument. Swap delay is enabled on the S5000 by default; a feature that gives users a 2 minute window to change sensors without triggering a fault condition. SafeSwap and Swap Delay are only applicable for XCell sensors. For more information on SafeSwap and Swap Delay, see 6 Maintenance.

WARNING!

  • As part of the product certification, it was verified that optional communication functions of this gas detection instrument while operating at the maximum transaction rate do not adversely affect the gas detection operation and functions of the instrument. The product certification, however, does not include or imply approval of the SafeSwap feature, communications protocol or functions provided by the software of this instrument or of the communications apparatus and software connected to this instrument.
  • Follow the warnings below when removing or replacing sensors. Reference Figure 3 for component overview.– Never remove or replace a Sensor Body Assembly or an IR Sensor while under power or when explosive hazards are present.– Confirm that the area is free of explosive hazards before removing or replacing an XCell Sensor under power.– To remove an XCell Sensor, unscrew XCell Sensor three full turns, wait 10 seconds, and then remove the XCell Sensor completely.

Failure to follow these warnings can result in serious personal injury or death.

NOTICE

When installing the IR Sensor, under no circumstances should a pry-bar be applied to the two legs that support the unit’s reflectors during installation or removal of the sensor. Applying force to the legs can permanently damage the IR Sensor.

3.2 Reviewing Shipment and Identifying Product Model

To determine the sensor type and options, check the shipping carton.

Passive, Digital, and IR sensors are shipped attached to the S5000. Passive and IR Sensors are one-piece sensors. Digital sensors comprise two parts: the Sensor Body Assembly and the XCell Sensor. Sensor Body Assemblies must be installed and tightened using a strap wrench. Check the sensor details before attaching to the S5000 housing. The sensor details are listed on the inside of the XCell Sensor. Unscrew the XCell Sensor from the sensor body assembly and check the label on the inside for gas type, range,configuration ordered, serial number, and firmware revision number.

3.3 Product Installation Check List

Before Installation

  • Review national electrical codes
  • Review local procedural and building codes
  • Determine optimum transmitter placement
  • Determine wire requirements
  • Determine mounting hardware requirements
  • Review approvals and ensure suitability for installation

Mounting

  • Attach appropriate sensor to housing or junction box (see 3.4.3 Sensor Orientation for proper sensor orientation)
  • Mount transmitter or junction box using appropriate mounting hardware
  • Confirm free air flow around the sensor

3.4 Mounting

Refer to 9 Appendix: General Certification Information before installation. Some toxic gases are provided in a fritless sensor housing.

Failure to follow this warning can result in serious personal injury or death.

3.4.1 Sensor Mounting Location

The best location for the transmitter and the sensor may not be the same location. Sensors should be placed in a location where a gas leak is most likely to be detected. When the best sensor placement would not allow the transmitter display to be easily viewed or accessed, a remote junction box can be used to mount the sensor remotely from the transmitter,allowing both to be installed in the optimum location. Two main factors should be considered when choosing a sensor location. The first is the density of the target gas relative to the air. Gases, such as propane, that are heavier than air should be placed near ground level while gases that are lighter than air should be placed above potential leak sources. Optimum sensor placement will depend on the surrounding processing equipment, such as pipes, valves, or turbines. MSA offers a gas and flame mapping service that systematically evaluates potential sources of leaks and recommends detector quantity and placement to create the most effective detection system.

3.4.2 Transmitter Mounting Location

The transmitter display should be mounted so that the screen is visible and easily accessed after installation. The electronics assembly inside the enclosure have one orientation inside the cylindrical housing. Take care to position the conduit entries and display so that the display is read in the correct orientation.

3.4.3 Sensor Orientation WARNING!

WARNING!

Mount the IR Sensor with the sensor inlet fitting extended horizontally from the main enclosure (see Figure 10 ) to preventthe build-up of particulate or liquid matter on the monitor’s optical surfaces. Mount the digital sensor with the sensor inlet fitting (see Figure 11 ) pointed downward; otherwise, the inlet may become clogged with particulate matter or liquids.

Failure to follow this warning can result in serious personal injury or death.

Sensor orientation will depend on the sensor type. If mounting an IR Sensor, whether locally on the transmitter or via remote junction box, the sensor should be mounted horizontally. If the IR Sensor is not mounted horizontally, the sensor will be prone to more frequent beam blocking issues due to accumulated dust and condensation on the surface of theIR Sensor. Figure 10 shows the correct and incorrect mounting orientations for the IR Sensor.

             Figure 10 Correct and Incorrect Mounting Orientations for IR Sensor

All other sensors, including electrochemical, catalytic bead, oxygen, passive catalytic bead, and passive MOS should be mounted vertically with the gas inlet pointed downward. If the sensor is not mounted with the gas inlet facing down, it is more likely to become clogged with particulate matter or liquids. Figure 11 shows the correct and incorrect mounting orientation for digital sensors. Passive catalytic bead and MOS sensors come already installed on the transmitter housing.

                   Figure 11 Correct and Incorrect Mounting Orientation for Digital Sensors

3.4.4 Connecting Sensor to Transmitter Housing or Remote Junction Box

Digital and IR Sensors are shipped attached to the main enclosure. The main sensor input is provided via a four-terminal connection that provides a digital interface for all sensor modules. Up to two sensors (excluding passive sensors) can be connected to a single transmitter with two analog outputs capable of representing the readings of the individual sensors. Passive sensors are shipped already attached and electrically wired to the device. Only one passive sensor can be used on a single S5000, and they are not interchangeable with other passive sensors or digital sensors. Consider the sensor dimensions when choosing a mounting location for the transmitter or junction box.

To connect the sensor:

  1. Loosen the set screw located on the lid using a 1.5 mm Allen wrench.
  2. Turn the lid counter-clockwise to remove.
  3. Pull out display module to expose terminal connections.                Figure 12 Terminal Connections
  4. Route the cable from the sensor through a conduit entry hole in the enclosure so that the sensor is oriented in the correct position (see 3.6 Electrical Power Connections for details).(Repeat to attach a second sensor to the S5000 transmitter).
  5. Connect the sensor to the “Sensor 1” position on the electronics assembly. a) If using a second sensor, connect it to the second sensor position.NOTICE  If only using one sensor and it is connected to “Sensor 2” position, the S5000 will enter Sensor Missing fault. See DisableSensor in 4.2.2 Sensor Setup for details on how to clear this fault.         Figure 13 Connecting Sensor to the                  Figure 14 SOURCE/SINK Switch Location            Stack and Grounding Terminal
  6. Verify the sensor connector is firmly seated on the terminal board.
  7. Attach the sensor’s ground to either of the grounding screws inside the S5000 housing.
  8. Set the analog output to SOURCE or SINK using tweezers, flat head screwdriver or similar tool.a) With the display board removed, locate “S1” switch on the main board (see Figure 14 ).b) Set “S1” switch in the required position:For SINK, set switch to the right side.For SOURCE, set switch to the left side.
  9. Replace the display module. Push firmly on the board stackNOTICE Ensure that the electronics assembly is fully engaged in the mounting holes. If not fully seated, the touch interfaceperformance can be negatively affected.

3.6.1 Electrical Warnings – Read before Connecting Power

WARNING!

  • Before wiring the S5000 transmitter, disconnect the power source supplying the transmitter and ensure no hazardous atmosphere present; otherwise, electrical shock or ignition of hazardous gases could occur.
  • Install wiring in accordance with the electrical code of the country in use, the local authority having jurisdiction and these installation instructions, as applicable.
  • Do not make any connections to the S5000 main board or junction box input, output, and relay connections while under power. Making connections under power could lead to electrical shock or ignition of a hazardous atmosphere.
  • Ensure that water and dirt are not able to enter the unit via the wire or conduit. If the unit is installed in a location known to be wet or damp, it is good practice to loop or bend the entry into the unit that prevents water incursion.
  • The internal grounding terminal (located on the interior metal board stack plate) must be used for equipment grounding. The external grounding terminal is only to be used as a supplemental bonding connection where local authorities permit or require such a connection.
  • As part of the product certification, it was verified that optional communication functions of this gas detection instrument while operating at the maximum transaction rate do not adversely affect the gas detection operation and functions of the instrument. The product certification, however, does not include or imply approval of the SafeSwap feature, communications protocol or functions provided by the software of this instrument or of the communications apparatus and software connected to this instrument.
  • Follow the warnings below when removing or replacing sensors. Reference Figure 3 for component overview.– Never remove or replace a sensor body assembly or an IR Sensor while under power or when explosive hazards are present.– Confirm that the area is free of explosive hazards before removing or replacing an XCell Sensor under power.– To remove an XCell Sensor, unscrew XCell Sensor three full turns, wait 10 seconds, and then remove the XCell Sensor completely.

Failure to follow these warnings can result in serious personal injury or death.

3.6.2 Retrofit Applications with S4000CH, S4000TH, or TS4000H

The S5000 was designed to be easily retrofitted with existing S4000CH, S4000TH, and TS4000H wiring. When replacing an existing S4000CH, S4000TH, or TS4000H with the equivalent S5000 sensor technology, the following items need to be checked in order for the S5000 to operate:

  1. Wire gauge needs to be 18-14 AWG
  2.  Sufficient power must be supplied to the S5000 in accordance with the maximum wire lengths. (See the tables in3.6.4 Power Load Requirements and Maximum Mounting Distances)If these requirements are met, performance of the S5000 should meet the noise immunity standard equivalent of the S4000CH, S4000TH, and TS4000H using the existing wiring; However, the installation may not meet the latest EMC EN50270 noise immunity standard that the S5000 meets with the grounding and wiring scheme as indicated in this manualand corresponding I/O drawing.

3.6.3 Electrical Hardware Requirements

Braided shielded, twisted pair, instrument quality wire or cable should be used to minimize the possibility of noise interference and contact with other voltages. Selection of shielded cable must comply with local requirements. Conduit, in addition to braided shielded wire, may also be needed in areas where a large amount of electrical noise isexpected. All cable shields should be terminated to earth ground at one end only. The S5000 has a four-wire power terminal, one four-wire communication terminal, and three four-wire sensor terminals. Relays can be added as an option. Terminals for power and relays can take wires up to 12 AWG while all other terminals take wires up to 14 AWG. Four conductors are also required for the S5000 remote junction boxes.

Incoming power and signal cables should be a braided shield cable such as Alpha Wire 3248 or equivalent. The braided shield must be terminated to the board stack as shown in Figure 27 , or alternatively, the earth ground at the user’s power source location.An external Class 2 power supply is required to supply 12-30 VDC to the S5000. Incoming power and signal cables should be a braided shield cable such as Alpha Wire 3248 or equivalent.

3.6.4 Power Load Requirements and Maximum Mounting Distances

Consider future needs when selecting cable size and power supply. The maximum distance between the S5000 transmitter and the power supply depends on the sensor configuration (sensing technology and one or two sensors), wire gauge, and the power supply voltage. The table below outlines the maximum transmitter mounting distances. First determine if thesensor(s) will be locally or remotely mounted. Then choose sensor type(s). The corresponding maximum power and mounting distances by wire gauge are shown.

3.6.6 Relay Electrical and Power Connections

Relay Board Stack OverviewThe S5000 can be purchased with three relays. Two of the relays can be configured for either de-energized (default) or energized and latching or non-latching. The third relay is a dedicated fault relay. All electrical connections to internal relays can be made directly on the PC board. The board is labeled for Normally Open (NO) and Normally Closed (NC) de-energized state.

Relay Specifications

Table 8 Relay SpecificationsIf using AC power, the relay wires should not be run within the same conduit or cable tray as the DC power supplied to theS5000 or the S5000 junction box. A separate wire entry on the device should be used for AC power connected to the relays. The S5000 is built with an additional wire entry to allow this.

Exceeding the volt-amp rating of the relay can cause damage to the switching contacts.

Relay Connections to Inductive Loads

If connecting the relays to motors, fluorescent lighting, or other inductive loads, it is necessary to suppress any sparks or inductive feedback that may occur at the relay contact. These effects may render the unit inoperative.One way to reduce these effects is to install a Quencharc® (P/N 630413) across the load being switched.

Fault Relay Wiring and Configurations

The Fault relay state in non-fault operating condition is Energized and terminal connections are supplied for Normally Closed and Normally Open. The energized fault relay setting provides an electrical path for fail-safe relay operation. In the event of any failure, including loss of power, the relay will change to the de-energized state to indicate a fault condition.The Fault relay state cannot be reconfigured

Relay Energy State and Terminal Connections

The S5000 relay states are labeled for the default de-energized state. The alarm/warning relay energy state can be changed on the device, which will exchange the normally open and normally closed terminals. The preferred relay energy state should be determined before making connections. Table 9 shows the terminal connections by energy state and isapplicable to both relay 1 and relay 2.

Table 9 Relay Terminal Connections by Energy State

4 Operation

WARNING!

Refer to 9 Appendix: General Certification Information before installation and operation.Failure to follow this warning can result in serious personal injury or death.

The S5000 Series gas monitor is factory calibrated and shipped with the most common default options to minimize set up effort. Using sensors, the device tests the ambient air and triggers an alarm as soon as the gas exceeds a specific concentration level.

4.1 Startup

4.1.1 Initial Startup

  • The first time the S5000 is powered on, the following will appear on the display:
  • S5000
  • Software Version No.
  • Sensor Warm-up
  • Wait

The S5000 will remain in Start-up mode in which the fault relay is de-energized and the analog output is 3.5 mA by default. The time the S5000 stays in Start-up mode depends on the sensor.Oxygen and Carbon Monoxide sensors require a 30 minute warm-up time before being fully functional. The device will be in fault during the 30 minute start-up time. All other sensor start-up times vary, the unit will be in fault for the first 2 minutes of the start-up time and the analog output signal will be at the maintenance level (3.5 mA default). A full calibration is recommended after one hour of a sensor being installed and acclimated to the environmental conditions. See 5 Calibration for calibration details

4.1.2 Sensor Warm Up Times

WARNING!

For optimal sensor performance, allow sensors 24 hours to acclimate to application conditions before performing an initial calibration

Failure to follow this warning can result in serious personal injury or death.IR Sensor: ≤ 10 minH2S: ≤ 5 minSO2: ≤ 5 minCl2: ≤ 10 minNH3: ≤ 5 minCat Bead: ≤ 5 minPassive MOS: ≤ 5 minPassive Cat Bead: ≤ 5 minCO: 30 min (see note)O2: 30 min

Carbon Monoxide sensor gas codes D10, D11, D12, and D14 may require initial warm-up periods longer than 30 minutes. If the 30-minute warm up is over, the sensor may show a positive reading that exceeds alarm levels. In the event of a shortterm power outage, the warm-up time for carbon monoxide gas codes D10, D11, D12, and D14 will be significantly less.See the table below to estimate required warm-up time.

Table 10 Warm Up Times CO

1- The minimum alarm level of all three CO sensors is 10ppm. Below this level would not cause an alarm on the device.

4.1.3 Startup after Power Failure

If the S5000 loses power, all of the settings are saved to the internal memory. When power is restored to the device, it will go back to the same settings as before the loss of power. To check the settings, go through the menu or view on the X/S Connect App.

4.2 Settings

The S5000 is a tool free transmitter. The infrared EZ touch button on the face of the display can be used to navigate through the menu structure. The button is designed for use with fingers with a “press” and “release” action, and works best without gloves. The button works the same as the magnet does with the S4000 menu.

Changing a value

  1. Press and hold EZ Touch button.
  2. Wait for relevant menu to scroll (each menu scrolls twice).
  3. Release to enter menu while it is scrolling.
  4. Use Press and Release function to change values.

The EZ touch interface can be disabled, but will require a password. Menu settings can also be activated using a magnet on the General Monitors logo. Values that are changed in the menu are saved after main setup loop “Finished”, except for sensor range selection under sensor setup. Each menu ends with “Finished?” scrolling twice on the display. If the button is not touched during “Finished?”, the menu will begin at the start again and scroll through the options and values again. The new values thatwere entered will be displayed on the first pass. When user exits a menu by touching “Finished?” and there isn’t a second sub menu, the previous menu will be displayedstarting at the menu that had just been used.

Some instrument settings are only configurable through Bluetooth® X/S Connect App, Modbus, or HART. See4.4 Setting only configurable via Bluetooth®, Modbus, or HART.

Disable Sensor (for Digital Sensors Only)

When removing a sensor from the transmitter while under power, the S5000 will enter a Sensor Missing fault condition after the two minute Swap Delay period has expired (if enabled). If Swap Delay is disabled, the transmitter will go into Sensor Missing fault immediately after removing the sensor from the transmitter. If the system is off at the time a sensor isremoved, the transmitter will go into fault after its startup sequence. This fault condition can be removed by disabling the affected sensor position. Disabling a sensor removes the fault and stops communications with the sensor, the sensor’s reading on the display is removed, and the mA channel for that sensor position is set to 0 mA. By default, the S5000 has the Sensor 2 position disabled. If at any time a sensor is connected to a position that is disabled, the device will automatically enable that sensor position.

To disable the sensor after removal:

Diffusion Supervision

Diffusion supervision actively monitors the sensor inlet for obstructions. If an obstruction is detected, the sensor will go into a fault mode to alert users and the control room that it is not seeing gas due to an obstruction. Objects residing directly on or in the sensor inlet that result in a significant impact to the gas path are very likely to be detected by DiffusionSupervision. Examples include paint, tape, water, and dirt. Small amounts of these materials can be visible on the inletbwhile not impacting the gas path enough to trigger a Diffusion Supervision Fault. A fault signal will only be sent out when the system determines that the amount of material that has accumulated on or inside the sensor inlet is negatively affectingthe gas path.

Even if a Diffusion Supervision Fault has not been triggered, it is good practice to clear any foreign material fromthe sensor inlet if any is observed while inspecting the sensor.

To enable or disable Diffusion Supervision:

  3. Select the desired sensor (Sensor 1 or Sensor 2) and touch button when “Finished?” is displayed.

The Life and Health information reports the general health of the sensor. XCell sensors with TruCal (Hydrogen Sulfide and Carbon Monoxide) calculate current sensor sensitivity using automated pulse checks. The pulse stimulates the sensor with a response similar to having actual calibration gas applied. The stimulated response is compared to the last calibration and will make adjustments to sensitivity to match the last calibration. When the required adjustment is greater than the accuracy of the algorithm’s adjustment, the sensor will call for a calibration.

All Digital Sensors, including catalytic bead and oxygen, will show life health status as ‘Good’ or ‘Fair’ with the following calculation: Good condition occurs when the current calibrated span sensitivity is greater than 50% of the way between the initial calibration sensitivity and the end-of-life span sensitivity. Fair condition occurs when the current calibrated span sensitivity is less than 50% of the way from the initial calibration sensitivity and the end of life span sensitivity.

NOTICEUsing expired calibration gas or the incorrect calibration gas can result in a premature “Fair” status.

4.4 Setting only configurable via Bluetooth®, Modbus, or HART

The following settings are only configurable through Bluetooth®, Modbus, or HART.

  • AO Custom Levels
  • Relay Zone – Horn Mode
  • Unit Device ID/Tag
  • Alarm Direction
  • Alarm Enable/Disable

4.4.1 AO Custom Levels

S5000 offers three factory defined analog outputs (AO) level sets, i.e., 0 mA with HART disabled, or 3.5 mA and 1.25 mA with HART enabled. Users can also specify their own custom AO levels for each transmitter mode. The Maintenance AO level is used during start up, Reset Main Unit, and Transmitter Settings Reset. Output setting for oxygen sensor calibration is not configurable. All changeable settings can be modified through Modbus/Bluetooth/HART.

Table 15 Default AO Values

The range for the changeable AO settings is 0.000 mA to 3.750 mA. The change step is 0.025 mA. Please note the HARTcommunication may not work reliably if the current level is set to below 1.25 mA.

4.4.2 Relay Zone – Horn Mode

Horn mode is designed to allow local acknowledgment of a relay-triggered horn, while the alarm state is still present. All alarms on both sensors trigger both relays, however the second relay can be acknowledged over Modbus/Bluetooth/HART.

4.4.3 Unit Device ID/Tag

This is device tag/name used to identify the unit during HART and Bluetooth communication. Default is “GM_S5K_0 “. Users can change this string to any characters from the following character set. The string length is limited to eight characters.

4.4.4 Alarm Direction

Relays can be triggered by an alarm threshold as gas readings increase or decrease. Most applications require increasing alarm thresholds, except for Oxygen monitoring, which is most often a decreasing alarm. The default alarm direction for Oxygen sensor is decreasing, or downward. The default alarm direction for all other sensors is increasing, or upward. The alarm direction can be set to increasing/upward or decreasing/downward. Alarm direction for Oxygen sensor can be changed through UI directly, or through Modbus/Bluetooth/HART. The alarm direction setting for all other sensors can only be changed through Modbus/Bluetooth/HART.

4.4.5 Alarm Enable/Disable

Users can disable alarms by changing this setting. Default value is Enabled for this setting. Users can change this setting to Enabled or Disabled.

5 Calibration

Calibration is the process of applying a known quantity of gas to the transmitter so that the transmitter can adjust the precision and accuracy of the measurements made in normal operating mode. This process ensures that gas measurements are as accurate as possible.

Calibration Warnings – Read before CalibratingAlthough S5000 sensors are factory calibrated, another calibration is recommended once the unit is installed in its final environmental destination.

WARNING!

Use zero gas when zeroing the S5000 transmitter if there is any possibility of background gas. Otherwise, improper calibration could occur. Use zero gas when zeroing IR700 sensors. Air contains CO2 and cannot be used. Nitrogen is recommended as a zero gas. Otherwise, improper calibration could occur. For optimal sensor performance, allow sensor to acclimate to application conditions for 24 hours before performing an initial calibration. Perform calibrations 24 hours after initial start up and at a frequency identified in 5.2 Calibration Frequency and 5.3 Calibration Frequency for XCell Sensors with TruCal (H2S & CO only) . XCell Sensors with TruCal (CO & H2S) with Calibration Alert enabled provide an indication for “Calibration Recommended” and “Calibration Required’. When either indication is provided by the device, calibrate the sensor.

Failure to follow this warning can result in serious personal injury or death.

5.1 Calibration EquipmentA gas cylinder with a known concentration of gas appropriate for the range of measurement is needed. Sensors come with preset span gas values appropriate for the measurement range.All of the calibration hardware for XCell sensors is included in a convenient calibration kit. It includes a carrying case that can fit two cylinders, a regulator, tubing, and any other accessories required for each sensor type. The calibration kit can be ordered separately or as a single line item with the gas cylinder. See Table 16 for a complete list of calibration cylindersand kits. The Digital Toxic, Oxygen, and Catalytic Bead sensors share the same sensor body design and use the same calibration hardware. The calibration kit for IR400 sensors is ordered separately (P/N 1400270-2) and contains a regulator, tubing, and other calibration accessories specific to the IR400. The calibration kit for IR700 sensors is P/N 31478-1.Passive sensors use different calibration hardware to accommodate the different sized sensor housing. Passive MOS sensors can be calibrated with either calibration gas cylinders or ampules. See Table 16 for P/N details.The sensor guard and rubber calibration cap should be removed after calibration.

Table 16 Calibration Kits

Flow Rates:CALKIT1 and 1400270-2 = 1 liter/min1400152-1 and 1400154-1 = 0.5 liter/minCALKIT2 = 0.25 liter/min

5.2 Calibration Frequency

The frequency of calibration gas testing depends on the operating time, chemical exposure, and type of sensor. Especially in new installations or applications, it is recommended that the first sensors be calibrated more often to establish the sensor performance in this particular environment. For this, record the “as found” and “as left” values and track the percent adjustment over time. Then, gradually extend calibration intervals until the percent adjustment is greater than the expected accuracy of the sensor.

5.3 Calibration Frequency for XCell Sensors with TruCal (H2S & CO only)

WARNING!

Certain conditions may prevent the performance of Diffusion Supervision and/or TruCal testing. If such a condition persists for 90 days, the XCell sensor with TruCal will recommend a calibration which is communicated through the transmitter display and LEDs. When Calibration Alert is enabled, the milli-amp signal output will also be driven to calibration alertoutput. Perform a calibration when the device recommends it.

Failure to follow this warning can result in serious personal injury or death.

5.3.1 XCell Sensor with TruCal and Diffusion Supervision (CO&H2S Only)Sensors with TruCal technology will adjust sensitivity without any manual intervention or calibration, unless called for by the sensor. If the adjusted sensitivity from TruCal deviates too far from the last gas calibration sensitivity, the sensor will recommend or, in extreme cases, require a calibration. When a calibration is recommended, the transmitter LED status indicators slowly pulse green. Users can also enable a Calibration Alert function that will send a milli-amp signal on the analog output to the control room when a calibration is recommended. When a calibration is required, the status LEDs will flash yellow and the transmitter will go into a Calibration Required Fault. With Diffusion Supervision and Calibration Alert enabled, the time between scheduled calibrations can be extended to 24 Months. If calibration alert and/or diffusion supervision are disabled follow the calibration frequency recommendation set forth in5.3.2 XCell Sensor with TruCal without Diffusion Supervision (CO&H2S Only).

5.3.2 XCell Sensor with TruCal without Diffusion Supervision (CO&H2S Only)Sensors with TruCal technology will adjust sensitivity without any manual intervention or calibration, unless called for by the sensor. If the adjusted sensitivity from TruCal deviates too far from the last gas calibration sensitivity, the sensor will recommend or, in extreme cases, require a calibration. When a calibration is recommended, the transmitter LED status indicators slowly pulse green. Users can also enable a Calibration Alert function that will send a milli-amp signal on the analog output to the control room when a calibration is recommended. When a calibration is required, the status LEDs will flash yellow and the transmitter will go into a Calibration Required Fault. Without Diffusion Supervision, regular calibration of the sensor must still be conducted to confirm the sensor inlet is not obstructed. Actual TruCal sensor performance will depend on the application, background gas exposure, and environment. To validateXCell sensors with TruCal, it is recommended that users follow their regular calibration cycle and record the “as found” and “as left” values, tracking the percent adjustment over time. Once a baseline is established, the calibration intervals can be extended until the percent adjustment is greater than the expected accuracy of the sensor.

5.4 Calibration Types: Zero vs. SpanThere are two types of calibration; zero and span calibration. The zero calibration resets the baseline level reading to zero. If the target gas is suspected to be occasionally present, it isbest to also use a zero gas cylinder during the zero calibration. If the target gas is not present in the atmosphere, an additional calibration cylinder is not required. The span calibration is a process that involves first zeroing the baseline reading, then applying a known amount of target gas so that the accuracy and precision of the transmitter can be adjusted to the known value. The known concentration of gas is called a “Span Value” because it represents the span or reach of the calibration curve from zero to that value.

The Sensor Span Value (i.e. Cal Level) in the device menu should be the same as the concentration listed on the calibration gas cylinder.

5.5 How to Zero Calibrate XCell and IR Sensors

NOTICE   If a password is enabled, you will not be able to proceed with the calibration without the password.

To abort, press the EZ touch button or apply magnet over GM logo before applying target gas. In the event that a calibration cannot be completed, the user can acknowledge the FAIL by pressing the EZ touch button or applying magnet to the GMI logo area until “Reset” is displayed and then release. The unit will revert to the settings of the last successful calibration.

WARNING!

The regulator used with the zero gas cylinders should not be the same as the regulator used for the target gas. The zero gas regulator can be contaminated with the target gas over time, and thus raise the detection baseline and make the sensor less sensitive to the target gas.

Failure to follow this warning can result in serious personal injury or death.

If there is no target gas in the atmosphere around the sensor, using a zero gas cylinder is optional. Note that, since air contains CO2, a zero gas cylinder is required for zeroing an IR 700 sensor. For IR700 sensors, nitrogen is recommended as the zero gas.

  1. Screw the sensor guard to the bottom of the sensor housing.
  2. Place the green calibration cap over the sensor guard inlet so that it is flush with the bottom of the sensor guard and completely covers the sensor guard inlet.
  3. Attach the tubing to the plastic stem protruding through the green calibration cap.
  4. Screw the regulator onto the top of the zero gas cylinder.If a password is enabled, you will need to enter it to access the menu system.NOTICE If the calibration cap cannot be used (such as for a remote sensor application), ambient wind conditions must be minimized during calibration to avoid a calibration with increased sensitivity.
  5.  Press EZ touch until Zero is displayed, and release.
  6. Once the screen displays Zero in Progress, turn on zero gas flow by turning knob on the regulator.
  7. Wait while the device displays Zero in Progress.
  8. Once the zero calibration is complete, a Zero PASS or FAIL is displayed. If PASS displays, the procedure is complete. If FAIL displays, the procedure was unsuccessful (see 6.5 Troubleshooting).
  9. Remove the zero calibration equipment from the device including the sensor guard and calibration cap.

Sensors with TruCal and have Diffusion Supervision enabled can go into Diffusion Supervision Fault if the green Calibration Cap is left on after completing a zero calibration.

WARNING!

The green Calibration Cap must be removed from the sensor after a zero calibration. Failure to do so could restrict gas flowto the sensor and result in erroneously low readings.

Failure to follow this warning can result in serious personal injury or death.

To abort, press the EZ touch button or apply magnet over GM logo before applying target gas. In the event that a calibration cannot be completed, the user can acknowledge the FAIL by pressing the EZ touch button or applying magnet to the GMI logo area until “Reset” is displayed and then release. The device will revert to the settings of the last successful calibration.If it is suspected that gases are present, it will be necessary to purge the sensor environment with zero air.

To calibrate the sensor:

  1. Attach a regulator to the zero gas cylinder (if using) and the calibration cylinder.
  2. Attach the plastic sensor guard to the bottom of the sensor housing if not already installed.
  3. Place the green calibration cap over the sensor guard inlet so that it is flush with the bottom of the sensor guard and completely covers the sensor guard inlet.
  4. Attach the tubing to the plastic stem protruding through the green calibration cap.
  5. Push the other end of the tubing over the zero cylinder regulator. Ensure the tubing completely covers the gas outlet.
  6. Press EZ touch until Calibration is displayed, and release.If a password is enabled, you will need to enter it to access the menu system.NOTICEIf the calibration cap cannot be used (such as for a remote sensor application), ambient wind conditions must be minimizedduring calibration to avoid a calibration with increased sensitivity.
  7. Select Sensor #1 or Sensor #2, and then select “Finished?” to start the calibration process.
  8. Once the screen displays Zero in Progress, turn on zero gas flow by turning knob on the regulator (if using).
  9. Wait while the device displays Zeroing.
  10. Once the Zero Calibration is complete, remove the tubing from the sensor guard inlet.
  11. The display will show Apply Gas. Attach tubing for calibration gas and turn on the regulator Display will show “Calibration in Progress”. “Calibration Complete Remove Gas” will show when span is complete.If “PASS” displays, the procedure is complete.If “FAIL” displays, the procedure was unsuccessful. See 6.5 Troubleshooting.
  12. Remove the calibration equipment from the device, including the sensor guard and calibration cap.

Sensors with TruCal and have Diffusion Supervision enabled can go into Diffusion Supervision Fault if the green Calibration Cap is left on after completing a calibration.

5.7 How to Calibrate an Oxygen XCell Sensor

An oxygen span gas cylinder is not needed if the sensor is in an area that maintains ambient air conditions. Follow the same process for XCell sensors as described in 5.6 How to Calibrate XCell Sensors. When the display prompts “Apply Span Gas”, simply allow the countdown to occur without applying gas. If the sensor is located in an area of normally low or enriched oxygen, then a 20.8% oxygen sample must be applied.

5.8 How to Calibrate an IR Sensor

A full span calibration is not required for the IR Sensors. Any degradation of the sensor’s performance is associated with slight drifts in its zero response. Restoring the sensor’s zero is typically sufficient. Note that for zeroing of the IR700 sensor, zero gas is required. Air contains CO2 and cannot be used. Nitrogen is recommended as the zero gas. The nitrogencylinder P/N is 1400262-17.See 5.5 How to Zero Calibrate XCell and IR Sensors for zero calibration instructions.If a full calibration of the IR Sensor is required, a larger calibration cap is used and covers the entire sensor guard during calibration. The calibration cap must be removed after completing the zeroing and/or spanning procedure

NOTICEIf the calibration cap cannot be used (such as for a remote sensor application), ambient wind conditions must be minimizedduring calibration to avoid a calibration with increased sensitivity.

5.9 How to Calibrate a Passive Sensor (Catalytic Bead or MOS)

The sensor calibration cup must be removed from the sensor after calibration. Failure to do so could restrict gas flow to the sensor and result in erroneously low readingsFailure to follow this warning can result in serious personal injury or death.

If a password is enabled, you will need to enter it to access the menu system.If the sensor is fitted with a sensor guard, calibration must be performed with the sensor guard in place.If it is suspected that gases are present, it will be necessary to purge the sensor environment with zero air.

To calibrate sensor:

  1. Attach a regulator to the zero air cylinder (if using) and the calibration cylinder.
  2. Attach the plastic calibration cup (P/N 1400152-1 or 1400154) to the bottom of the sensor if not already installed.
  3. Attach the tubing to the plastic stem protruding through the calibration cup.
  4.  Push the other end of the tubing over the zero cylinder regulator. Ensure the tubing completely covers the gas outlet.
  5. Press EZ touch until Calibration is displayed, and release the touch.
  6. Turn on zero gas flow by turning knob on the regulator (if using).
  7. Unit will start flashing the sensor life. Tap the EZ Touch if you want to reset the sensor life.
  8. Wait while the device displays “Zero in Progress”.
  9. Once the Zero Calibration is complete, remove the tubing from the calibration cup inlet.
  10. The display will show “Apply Gas”. Attach tubing for calibration gas and turn on the regulator.
  11. Display will show “Calibration in Progress”.
  12. “Calibration Complete. Remove Gas” will show when span is complete.
  13. Turn off the calibration gas regulator. Remove the calibration equipment from the device, including the calibration cup.Unit will return to normal operation.If “Cal Fail” and fault code displayed, the procedure was unsuccessful. See 6.5 Troubleshooting.

5.10 XCell Catalytic Bead Failsafe

Catalytic bead sensors require the presence of oxygen in order to sense combustible gas. In the event of very large combustible gas leaks that exceed 100 % LEL, enough oxygen can be displaced so that the sensor’s response to gas is no longer proportional to the calibration profile. The XCell catalytic bead has a locking fail safe mechanism that prevents thefalse reporting of a safe condition while the % LEL concentration is still above 100 % LEL. When the gas concentration exceeds 100 % LEL, the sensor will go into LOC over range.To clear the LOC over rage, the user needs to acknowledge and calibrate the sensor. To acknowledge LOC over range, press the EZ touch button or apply magnet to the GMI logo area until “Reset” is displayed and then release. This will allow a recalibration of the sensor to clear the LOC condition.

WARNING!

Ensure that the area has been cleared of gas before acknowledging the LOC Over Range and recalibrating the sensor.Failure to follow this warning can result in serious personal injury or death.

5.11 Calibration Confirmation

The S5000 Series Monitor records the date of the last successful calibration. This date can then be displayed via the Status Menu.

6 Maintenance

WARNING!

Use only genuine MSA replacement parts when performing any maintenance procedures provided in this manual. Failure to do so may seriously impair sensor and gas monitoring performance, alter flameproof/explosionproof characteristics or void agency approvals. Failure to follow this warning could cause the product to fail to perform as designed and persons whorely on this product for their safety could sustain serious personal injury or loss of life. Repair or alteration of the S5000 Gas Monitor, beyond the scope of the maintenance procedures provided in this manual or by anyone other than authorized MSA service personnel, could cause the product to fail to perform as designed and persons who rely on this product for their safety could sustain serious personal injury or loss of life. The S5000 Gas Monitor is constantly performing a self-check. When a problem is found, it displays the appropriate errormessage (see 6.5 Troubleshooting). When a critical error is detected within the device, the 4-20 mA output signal goes to a fault condition of 0 mA, 1.25 mA, 3.5 mA or user defined level.

6.1 IR Sensor Cleaning Procedure

The presence of particulate matter, oil films, liquid water, or the residue from water drops on the two monitor windows can adversely affect its performance. The sensor guard is designed to prevent foreign solids or liquids from reaching the monitor’s optical system. Additionally, heating elements are incorporated into the device to prevent water condensation.Under severe conditions, however, some material may collect on these surfaces and it may be necessary to occasionally check and clean the windows. While both windows are made of a highly durable material that is not easily scratched, avoid excessive pressure when cleaning them. Clean, cotton-tipped applicators are the most convenient tool to remove material collected on the windows.

  1. Remove the sensor guard.
  2. Use a dry applicator or one moistened with distilled water to wipe the window and remove dust.
  3. Use an additional clean, dry applicator to remove any residual water.
  4. Use an applicator moistened with isopropyl alcohol to remove heavy deposits of solids, liquids or oil films. Clean the window again with a second applicator moistened with distilled water; then, dry the window with a final applicator. Avoid using excessive amounts of water or alcohol in the cleaning procedure, and inspect the window to ensure that the entire surface is clean.
  5. The device will go into a “Cleaning required” fault with an analog output of 2.0 mA when cleaning is needed. The S5000 analog output may go down to 1.25 mA while the optical path is blocked, and display will indicate “Beam Block”.While in “Beam Block” fault, the sensor will not respond to the presence of gas
  6. When cleaning is done and the objects are removed from the sensor window, the device returns to normal operation. If water or isopropyl alcohol was used, allow the device to operate for 15 minutes to completely dry before replacing the sensor guard continuing to monitor for combustible gas.
  7. Replace the sensor guard.When the cleaning process is complete, be sure to remove all objects from the light path. It is recommended to check the sensor’s response to zero and calibration gas after cleaning.

WARNING!

Do not place foreign objects in the sensor’s analytical region (except per the “S5000 IR Sensor Cleaning Procedure” as described above); otherwise, the infrared beam can be partially blocked, causing the sensor to generate false readings. All objects must be removed from the sensor’s analytical region for it to function properly.Failure to follow this warning can result in serious personal injury or death.

6.2 Replacing an XCell Sensor

The only routine maintenance item is the sensor, which has a limited lifetime. The S5000 sensors with TruCal technology will indicate when the sensor is near end of life through the Status Menu. When the Sensor Life & Health status is “Fair”, there is approximately 2 month time frame to replace the sensor before it will no longer function. Actual time between “Fair”status and sensor end of life depends on exact environmental conditions. When a TruCal sensor is no longer capable of sensing it will go into fault and LEDs will flash yellow. It is good practice to obtain a replacement sensor before the sensor within the unit becomes inoperative. There is no need to open the main enclosure. Simply unscrew the sensor assembly located on the bottom of the main assembly.

WARNING!

  • Do not disassemble the sensor assembly. The sensing element inside may contain hazardous material.
  • Handle the sensor carefully; the electrochemical version is a sealed unit which contains a corrosive electrolyte.
  • Any leaked electrolyte that comes in contact with skin, eyes or clothes can cause burns.
  • If any contact with the electrolyte does occur, immediately rinse with a large quantity of water. On contact with the eyes, rinse thoroughly with water for 15 minutes and consult a doctor.
  • Do not install a leaking sensor in the sensing head assembly.
  • A leaking sensor must be disposed of in accordance with local, state and federal laws.
  • As part of the product certification, it was verified that optional communication functions of this gas detection instrument while operating at the maximum transaction rate do not adversely affect the gas detection operation and functions of the instrument. The product certification, however, does not include or imply approval of the SafeSwap feature, communications protocol or functions provided by the software of this instrument or of the communications apparatus and software connected to this instrument.
  • Follow the warnings below when removing or replacing sensors. Reference Figure 3 for component overview.– Never remove or replace a Sensor Body Assembly or an IR Sensor while under power or when explosive hazards are present.– Confirm that the area is free of explosive hazards before removing or replacing an XCell Sensor under power.– To remove an XCell Sensor, unscrew XCell Sensor three full turns, wait 10 seconds, and then remove the XCell Sensor completely.

Failure to follow this warning can result in serious personal injury or death.

Identify the sensor assembly needed via the A-5K-SENS code on the interior sensor label and obtain the appropriate sensor assembly; replace sensor assembly. Figure 33 Removing the XCell Sensor

Figure 34 Digital Sensor – Position of Labels

Alarm set points, span value, full scale limit and alarm direction will not change when replacing a sensor with the same gas type. Alarm set points, span value, full scale limit and alarm direction will change to the new sensor’ settings when replacing a sensor with a different gas type.

The S5000 Gas Monitor is shipped with the Sensor Swap Delay enabled. IF enabled, the 4-20 mA output signal goes to 3.5 mA and the FAULT relay will hold off a fault indication for 2 minutes. This setting allows the operator to exchange sensor modules without a FAULT indication.It is recommended that all other maintenance be performed at an MSA factory-authorized service center.

6.3 Clearing a Blockage

If using a Digital Sensor with Diffusion Supervision, and if the Diffusion Supervision feature has been enabled in the Sensor Settings, the sensor will notify the user if it detects foreign material obstructing the sintered metal frit where gas would normally enter the sensor (see Frit Location). When this condition is detected, the transmitter will go into fault and show “Diffusion Supervision Fault” on the display. Follow these recommended steps to attempt to clear this fault:

  1.  Inspect and clear the sensor inlet and frit.
  2. Inspect and clear any accessories attached to the sensor.
  3. Ensure Sensor is fully mated to the Sensor Body Assembly.
  4. Attempt to recalibrate the Sensor.
  5. Disable Diffusion Supervision or replace the Sensor.First, with the sensor still installed, visually inspect the sensor to see if any objects are covering the gas inlet and remove them. Example objects may include tape or the green Calibration Cap. Next, check to make sure that there is no foreign material stuck to the frit. If any material is found, gently remove it while considering any hazards that may arise from suchan action, like the accumulation of a static charge, and taking the necessary steps to avoid them. Take care to ensure that the frit is not damaged during the cleaning process. DO NOT use water or liquids to try to clean the frit. The frit acts like a sponge and will retain liquids, which will keep the gas path blocked.

WARNING!

The sensor relies on the frit as a part of its Flameproof/Explosionproof approval. If the frit is damaged while attempting to clean it, immediately remove power from the device. Ensure the area is free of a hazardous atmosphere, then follow all steps as outlined in this manual to properly replace the sensor. Failure to follow this warning can result in serious personal injury or death.

If no material is visible, the frit may still be blocked by a liquid which has absorbed into the frit. Once absorbed, liquids are very difficult to remove. For these situations, relying on natural evaporation is recommended. Due to the time it can take for liquids to evaporate sufficiently from the frit, users may want to consider swapping out the affected sensor with one that isknown to be clear. Placing absorbent material against the outer surface of the frit can help accelerate this process.If a sensor is in Diffusion Supervision Fault, the device will still allow the user to attempt to calibrate the sensor. In the rare event that a sensor calibration is successful, but the Diffusion Supervision system continues to detect a blockage in the gas path, the Diffusion Supervision Fault will return in approximately 24 hours. In this scenario, there is likely an environmental factor affecting the Diffusion Supervision detection. Provided the sensor can successfully calibrate, the sensor is still capable of detecting gas. To prevent the Diffusion Supervision Fault from reoccurring, a user can either disable Diffusion Supervision in the Sensor Settings (see 4.2.2 Sensor Setup) or replace the sensor.

6.4 Replacing a Passive Sensor (Cat Bead or MOS)

When the passive Catalytic Bead or MOS sensor is damaged or gradually losing sensitivity and eventually fails to respond to gas adequately or fails to pass calibration, the sensor needs to be replaced. The mounting threads of the sensor head may require lubrication. Grease must not be used. As an alternate, PTFE (Teflon) tape may be used on sensor threads.

To replace the passive sensors:

  1. Declassify the area and make sure there is no hazardous gas/vapor present.
  2. Power down the S5000 transmitter.
  3. Unscrew the lid.
  4. Remove the User Interface Module.
  5. Refer to the sensor wiring diagram label inside the S5000 transmitter to locate the sensor connector and unplug it from the transmitter.
  6. Unscrew the sensor head until it is totally off. Guide the sensor wires so they will not get caught by the internal parts of the S5000 while sensor head is turning.
  7. Guide the connector and wires of the new sensor head through the conduit entry for sensor. Do not plug in the sensor connector at this time.
  8. Screw in the new sensor head. Guide the sensor wires so they will not get caught by the internal parts of the S5000 while sensor head is turning.
  9. Verify the sensor connector wiring against the wiring diagram.
  10. Plug in the connector to the indicated header and make sure they are mated correctly.

10 Appendix: HART Specific Information

The S5000 Gas Monitor is available with an optional HART (Highway Addressable Remote Transducer) output communications protocol. With this option, the S5000 complies with HART Protocol Revision 7 and uses the 16-bit manufacturer and device codes. This document specifies all the device specific features and documents HART Protocol implementation details (e.g., the Engineering Unit Codes supported). These specifications assume the reader is somewhat familiar with HART Protocol requirements and terminology. This specification is a technical reference for HART-capable HOST Application Developers, System Integrators and knowledgeable End Users. It also provides functional specifications (e.g., commands, enumerations and performance requirements) used during Field Device deployment, maintenance, testing, and operations. It is recommended that the 4- 20 mA output be the primary gas monitoring signal. The HART signal can be the secondary method.
