CLIPSAL Light Level Detector Surface Mount Installation Guide
Introduction
The 5754PE Light Level Detector is a C-Bus input unit that measures the ambient light level and converts this information into messages that are sent across the C-Bus network. Ambient light levels are compared to the user-defined target light level. Control messages are then sent to output units to alter the lighting levels as required, for example, using the RAMP TO LEVEL command issued to a dimmer unit. The surface mount detector is designed for mounting on stone or concrete or any location where it is not practical to install other types of detectors. The 5754PE is held in place by two screw anchors. The detector is powered by the C-Bus network and does not require a separate power supply unit. The 5754PE is an Extra Low Voltage (ELV)/Class 2 device.
Safety and Product Handling
The light level detector is for indoor use only with C-Bus systems. It is never connected to building power or an external power supply. Read and follow all instructions found on the product and its packaging.
WARNING Avoid Electrical ShockDo NOT connect the unit to building power or any telephony or Internet equipment. The detector is a Class 2, extra low voltage (ELV) device. Do NOT connect the unit to an external power supply or a non-C-Bus network.Use caution when drilling holes in ceilings. Check for the presence of electrical wiring and water pipes before drilling.
Caution Sensitive Components InsideStatic discharge and rough handling can damage the components on the circuit board. Use anti static procedures when handling the opened unit. Avoid touching the photo sensor and other electronic components.Changes or modifications not expressly approved by Clipsal could void the user’s authority to operate the equipment (under FCC rules).
Caution Avoid Damage to the LensThe fresnel lens is easily scratched. Scratches on the lens will reduce the accuracy of the detector. Use care when installing and configuring the unit.
Installation
The detector is for indoor use only. Do not place the unit where it will be exposed to dripping water, steam or direct sunlight. During the installation process, do not remove the lens from the top cover. To install the light level sensor you will need 2 fasteners to secure the unit to the ceiling. Select hardware suited to the mounting surface. Screws or anchors are not provided with the detector.
Removing the Top CoverThe detector housing consists of two pieces, the base and the cover. No tools are required to remove the cover. To remove the top cover grasp the base with one hand and rotate the top anti-clockwise with your other hand. Refer to the illustration below:
Figure 1. Removing the top cover To install the cover, make sure the tabs are aligned with the slots and rotate the cover clockwise until it locks in place.Installing the Mounting HardwareThe base of the detector is secured in two places (see Figure 2). Drill the holes for the screws or anchors and then follow instructions for mounting the detector.
Figure 2. Mounting hole locations in the base.
Mounting the DetectorPass the network cable through the wire entry hole and then attach the detector’s base to the ceiling using the two screws or anchors as described in Section 3.2. The network wiring to the detector must be supported properly.
Connecting the C-Bus Network WiringUse Cat 5e Unshielded Twisted Pair (UTP) C-Bus cable. The use of bootlace ferrules (crimps) for screw terminals is recommended for a reliable connection. C-Bus cable conductor assignments are provided in Table 1. The Clipsal catalogue numbers for the C-Bus network cable is 5005C305B (solid conductors) and 5005C305BST (stranded conductors).

Table 1. C-Bus network cable conductor definitions
The C-Bus network uses polarised twisted wire pairs. The detector has two removable screw-type connectors. Strip the insulation from the twisted pairs and then connect the C-Bus positive (+) and C-Bus negative () twisted pairs to the screw terminals as shown in Figure 3.
Figure 3. C-Bus wiring diagramPush the terminal plugs onto the pins on the circuit board. It is recommended that you seal the entry hole area with silicon rubber to keep dust and debris out of the detector. Install the top cover by aligning the tabs on the slots and rotating the top cover in a clockwise direction.Note: The Remote On and Remote Off signals are not used on the detector, but you should maintain these signal connections throughout the network.
Programming
The detector unit must be programmed with a unique unit address. This is done using C-Bus Toolkit software, available at the Clipsal Integrated Systems (CIS) web site, http://www.clipsal.com/cis. Go to the Technical section and select ‘Downloads. The adjustable trimpots (Trimpot A and Trimpot B) work in conjunction with C-Bus programming parameters to set the operating mode for the unit:
During programming, selectable group addresses are assigned for the following:
- Light level target
- Light level margin
- High lux level
- Low lux level
Programming can also define a selectable block for High/Low lux levels that can be controlled by a group.
- Light level threshold
- Light level margin
- Low level threshold
- High level threshold
The C-Bus Group controls the high and low lux levels. Where a parameter is controlled by a C-Bus group, the value of the parameter is defined as: Value defined in Toolkit x Percentage of C-Bus Group x Percentage of POT (if assigned).Refer to C-Bus Toolkit Help files for additional information about setting the target light level using the GUI.
Field Calibration
For lighting control applications, the light level sensor must be calibrated to attain the desired target illumination level. Enter the desired lux value using the Toolkit GUI to directly specify the target ambient light level in lux. Keep the cover on the unit when performing tests. Remove the cover to adjust the trimpots, as required, and then replace the cover. Using a hand held light meter can be helpful when making adjustments in specific areas, such as workstations or conference rooms.Note: Care must be taken to ensure proper accounting for any resulting offset. Take into account that the light level at work surfaces will be different from the ambient light level present at the sensor unit due to proximity to light sources, shadows or diffusion effects. Refer to Toolkit Help for detailed information about light level sensors.
Caution. Avoid Lens DamageThe fresnel lens is easily scratched. Scratches on the lens will reduce the accuracy of the detector unit. Use care when handling the top cover.
POT A, Light Level Adjustment, Trimpot A on the PCB is a potentiometer that adjusts the light level for calibration and for setting levels used when programming the unit with the Toolkit GUI.POT B, Light Level Threshold Adjustment, Trimpot B adjusts the light level threshold for the ambient light in the measured area.LED 1, Status of group. This orange LED is on when the assigned network group is active.LED 2, Light level maintenance active LED. This red LED is on when light level monitoring is active, so the unit will be actively monitoring the lighting level and controlling a group to keep the light level in the monitored area within Light Level Target +/- Light Level Threshold. To set the light level, follow these steps:
|
1. |
Connect the detector to the C-Bus Network and allow a few seconds for the unit to stabilize. Remove the top cover by rotating it in an anti-clockwise direction. |
|
2. |
Turn POT A to its maximum value, fully clockwise. Do not force the adjustment screw beyond its range of travel. This setting allows the detector to respond to ambient light depending on the current C-Bus toolkit setting. |
|
3. |
Install the cover. Using C-Bus Toolkit software, set the target light level to the selected value and set up the detector to control a load with Sunset function. In this case there is no need to set a timer. The load will turn on when the Light Level is less than Target – Threshold and it will turn off when the Light Level is greater than Target + Threshold. |
|
4. |
Remove the cover and adjust POT A (turning anti-clockwise) as necessary to take advantage of ambient light. The cover must be in place during testing. |
|
5. |
Adjust POT B as necessary for the desired threshold. After making setting changes to the pots, replace the cover and recheck the operation of the detector. |
