SAFETY ALERTSThe symbols below are used on the equipment and throughout this document to draw the user’s attention to important operational and safety information.

CAUTION:Read the manual thoroughly before installing and operatingthe equipment.

CAUTION OR DANGER: Electrical shock hazard

All safety related instructions that appear in the manual must be observed to ensure personal safety and to prevent damage to either the instrument or the system. If the instrument is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.

INSTALLATION / CONECTIONSThe controller must be fastened on a panel, following the sequence of steps described below: · Prepare a panel cut-out according Specifications; · Remove the mounting clamps from the controller; · Insert the controller into the panel cut-out; · Slide the mounting clamp from the rear to a firm grip at the panel.RECOMMENDATIONS FOR THE INSTALLATION· All electrical connections are made to the screw terminals at the rear of the controller.· To minimize the pick-up of electrical noise, the low voltage DC connections and the sensor input wiring should be routed away from high-current power conductors. If this is impractical, use shielded cables. In general, keep cable lengths to a minimum.· All electronic instruments must be powered by a clean mains supply, proper for instrumentation.· It is strongly recommended to apply RC’S FILTERS (noise suppressor) to contactor coils, solenoids, etc. In any application it is essential to consider what can happen when any part of the system fails. The controller features by themselves can not assure total protection.ELECTRICAL CONNECTIONSFig. 01 below shows the electrical terminals of the controller:

Table 01 Input typesThe input type should be the first parameter to be configured on the controller. Any modifications on the input type will automatically change other related parameters. The user must verify the configuration every time that an input type modification occurs.OUTPUTS The controller has two outputs. The user can configure these outputs to operate as Control Output ((trl) or Alarm Output (al).OUT1 – Output Voltage pulse, 5 Vdc / 25 mA or Output Relay SPST-NOOUT2 – Output Relay SPST-NOCONTROL OUTPUT ((TRL) The control strategy can be ON/OFF (when PB = 0.0) or PID. The PID parameters can be automatically determined enabling the autotuning function (ATvN).ALARM OUTPUT (al) The controller contains 2 alarms that can be directed (assigned) to any output channel. The alarm functions are described in Table 02.

ierr

Alarms of the Sensor Break (Sensor Break Alarm). It is activated when the Input presents problems such as interrupted sensor, bad connection, etc.

Table 02 Alarm functions

Important note: Alarms configured with the ki, dif, and difk functions also trigger their associated output when a sensor fault is identified and signaled by the controller. A relay output, for example, configured to act as a High Alarm (ki), will operate when the SPAL value is exceeded and also when the sensor connected to the controller input is broken.

INITIAL BLOCKING OF ALARMThe initial blocking option inhibits the alarm from being recognized if an alarm condition is present when the controller is first energized (or after a transition from run YES NO). The alarm will be enabled only after the occurrence of a non alarm condition followed by a new occurrence for the alarm.The initial blocking is useful, for instance, when one of the alarms is configured as a minimum value alarm, causing the activation of the alarm soon upon the process start-up, an occurrence that may be undesirable.The initial blocking is disabled for the sensor break alarm function ierr.

OFFSETAllows fine adjustments to the PV reading for compensation of sensor error.

OPERATIONThe controller’s front panel, with its parts, can be seen in the Fig. 02:

Increment key and – Decrement key: allow altering the values of the parameters.Back key: used to retrocede parameters.OPERATION When the controller is powered up, it displays its firmware version for 3 seconds, after which the controller starts normal operation. The value of PV and SP is then displayed and the outputs are enabled. In order for the controller to operate properly in a process, its parameters need to be configured first, such that it can perform accordingly to the system requirements. The user must be aware of the importance of each parameter and for each one determine a valid condition. The parameters are grouped in levels according to their functionality and operation easiness. The 3 levels of parameters are1 Tuning / 2 Input / 3 CalibrationThe “P” key is used for accessing the parameters within a level. Keeping the “P” key pressed, at every 2 seconds the controller jumps to the next level of parameters, showing the first parameter of each level:PV >> atvn >> type >> PASS >> PV …To enter a particular level, simply release the “P” key when the first parameter in that level is displayed. To walk through the parameters in a level, press the “P” key with short strokes. To go back to the previous parameter in a level, press : Each parameter is displayed with its prompt in the upper display and value/condition in the lower display. Depending on the level of parameter protection adopted, the parameter PASS precedes the first parameter in the level where the protection becomes active.

rstr Pas.( Prot

Restore. Restores the factory calibration for all inputs and outputs, disregarding modifications carried out by the user.Password Change. Allows defining a new access password, always different from zero.Protection. Sets up the Level of Protection. See Table 03.

CONFIGURATION PROTECTION

The controller provides means for protecting the parameters configurations, not allowing modifications to the parameters values, avoiding tampering or improper manipulation. The parameter Protection (PROt), in the Calibration level, determines the protection strategy, limiting the access to particular levels, as shown by the Table 03.

PROTECTION LEVEL 1 2 3 4

PROTECTION LEVELSOnly the Calibration level is protected. Calibration and Input levels. Calibration, Input and Tuning levels. All levels are protected, including SP.

Table 03 Levels of Protection for the Configuration

ACESS PASSWORDThe protected levels, when accessed, request the user to provide the Access Password for granting permission to change the configuration of the parameters on these levels.The prompt PASS precedes the parameters on the protected levels. If no password is entered, the parameters of the protected levels can only be visualized.The Access Password is defined by the user in the parameter Password Change (PAS.(), present in the Calibration Level. The factory default for the password code is 1111.PROTECTION ACCESS PASSWORDThe protection system built into the controller blocks for 10 minutes the access to protected parameters after 5 consecutive frustrated attempts of guessing the correct password.MASTER PASSWORDThe Master Password is intended for allowing the user to define a new password in the event of it being forgotten. The Master Password doesn’t grant access to all parameters, only to the Password Change parameter (PAS(). After defining the new password, the protected parameters may be accessed (and modified) using this new password.The master password is made up by the last three digits of the serial number of the controller added to the number 9000. As an example, for the equipment with serial number 07154321, the master password is 9 3 2 1.Controller serial number is displayed by pressing for 3 seconds.

DETERMINATION OF PID PARAMETERSDuring the process of determining automatically the PID parameters, the system is controlled in ON/OFF in the programmed Setpoint. The auto-tuning process may take several minutes to be completed, depending on the system. The steps for executing the PID autotuning are:· Select the process Setpoint.· Enable auto-tuning at the parameter “Atvn”, selecting FAST or FULL.The option FAST performs the tuning in the minimum possible time, while the option FULL gives priority to accuracy over the speed.The sign TUNE remains lit during the whole tuning phase. The user must wait for the tuning to be completed before using the controller.

During auto tuning period the controller will impose oscillations to the process. PV will oscillate around the programmed set point and controller output will switch on and off many times.If the tuning does not result in a satisfactory control, refer to Table 04 for guidelines on how to correct the behavior of the process.
