Failure to do so may void the warranty. Unpacking Unpack the CPS-2C and inspect contents for damage. Should the contents appear to be damaged, contact your local distributor to return the equipment. The package should contain the following standard items:... -
Page 9: General Installation Guidelines
CPS-2C INSTALLATION General installation guidelines CPS-2C Control It is recommended to install the unit in a hallway to limit the CPS-2C exposure to noxious gases. In order to avoid condensation problems inside the controller, it is recommended to install the CPS-2C on an inside wall. If it is not possible, use spacers to have an air gap between the wall and the CPS-2C. -
Page 10: Electrical Power
CPS-2C INSTALLATION Electrical Power Protection from electrical surge should be included in the planning of each installation. It is strongly recommended to have a backup power source to ensure life- sustaining conditions in case of power failure (see figure 4). -
Page 11: Connection Procedure
The inside temperature sensor should be located in the area which gives the most accurate temperature reading to achieve optimum ventilation. The sensor should also be connected to the CPS-2C with a shielded two-wire cable. It should be located in an area protected from operating machinery, animal bites, personnel or anything that could damage the sensor. -
Page 12: Typical Power Backup Wiring
CPS-2C INSTALLATION Typical Power Backup Wiring A backup relay (DPDT) connects to the power source 1 in normal operation but will switch to the power source 2 if source 1 is disabled. The backup relay should be selected to ensure it is able to support the required power load. -
Page 13: Typical Alarm Connection Wiring
CPS-2C INSTALLATION Typical Alarm Connection Wiring The CPS-2C provides a normally closed dry contact to set off an alarm in case low or high temperature condition occurs. Moreover, this same contact can be used to signal a power failure or other malfunctions. It may be connected to an alarm system or directly to a siren and /or auto-dialer. -
Page 14: Powering Up Procedure
CPS-2C INSTALLATION Powering Up Procedure Once the CPS-2C is properly mounted on the wall and all modules and sensors connected to the terminal block, perform the following step: Verify all Connections Seal all cable entry holes. Hermetically Close the CPS-2C Close the front panel and the lower access cover. -
Page 15: Downloading The Configuration
There are two ways to download a configuration in the CPS-2C controller. 1) Downloading by powering down. A. Ensure the power source of the CPS-2C is OFF (flip the circuit breaker on the distribution panel). B. Remove the faceplate screws and lift up the cover. -
Page 16: Uploading The Configuration
E. When the uploading procedure is complete, remove the configuration chip (MMX) and place it in the bottom part of the enclosure or in another safe location. Once the MMX Chip is removed, the CPS-2C will continue to execute the configuration. -
