INSTALLING STATION MODULES
The Pro-C controller is supplied with a factory-installed base
module for up to 4 stations. Additional modules may be added in
increments of 3 stations (PCM-300), 9 stations (PCM-900), or
16 stations (PCM-1600). In total, a conventionally wired system
can be expanded up to 23 stations. Additional modules are sold
separately.
The Pro-C is also compatible with the EZ Decoder System
(EZDS) for hybrid conventional and two-wire operations. Add
a Pro-C Decoder Module (PC-DM) to enable control for up to
32 total stations. This system uses the same EZ-1 decoders
used with ICC2 and HCC controllers. For more installation and
programming details, please refer to the PC-DM Installation
Guide.
Installing PCM Modules
The Pro-C controller is designed with a simple-to-use “Power
Lock” feature that assures that the modules are energized and
firmly secured into the controller. The “Power Lock” can unlock
or lock all modules at once or at the same time by simply pushing
the “Power Lock” slide.
1. Slide the “Power Lock” into the “Power Off” (unlocked)
position. Insert the PCM or PC-DM modules into the
appropriate sequential position in the controller cabinet.
2. Once all of the modules are in place, slide the “Power Lock”
into the “Power On” (locked) position to energize and secure
the modules into the controller.
3. The Pro-C will automatically recognize the correct number of
stations. It is not necessary to press the reset button on the
back of the facepack or cycle power to the controller.

NOTE: To expand your controller to or
stations with a PCM- or PCM-,
respectively, install one PCM- in the

install the PCM- or PCM- in the
upper two expansion slots. These modules
will not t or operate in any other station
output slot.
