Connecting Station Modules

The Pro-C controller is supplied with a factory-installed base module for up to 3 stations. Additional modules may be added in increments of 3 stations (PCM-300) or a single 9-station (PCM-900) to expand the controller’s station capability to 15 stations. Additional modules are sold separately.

NOTE: The use of a PCM-900 to expand your controller to 15 stations requires that one PCM-300 be installed in the first slot (stations 4-6) and the PCM-900 in the upper two slots.

The Pro-C controller is designed with a simple to use Easy-Lock™ feature that assures that the modules are firmly secured into the controller. The Easy-Lock can lock or unlock all modules at one time by simply pushing the Easy-Lock slide.

1. When installing additional modules, it is recommended that the AC power be turned off at the controller.
2. Slide the Easy-Lock into the unlock position. Insert the module(s) into the appropriate sequential position in the back of the controller.
3. Once all of the modules are in place, slide the Easy-Lock into the locked position to secure all the modules into the controller.
4. Reactivate power to the controller. Turning the power off and on again permits the microprocessor to recognize the newly installed modules. You can also use the reset button on the back of the front panel to reset the microprocessor to recognize additional modules.

NOTE: The Easy-Lock feature was added to Pro-C controllers dated coded 12/01/02 or newer.
