The ICC controller is supplied with one factory-installed station module for up to 8 stations. Additional modules may be added in increments of 4 or 8 stations to expand the controller’s station capability (maximum of 32 stations with plastic cabinet and maximum of 48 stations with metal or stainless steel cabinet). Additional modules are purchased separately.

1. ICM modules now have a Positive-Lock™ feature that fastens the module securely into the ICC. Rotating the Positive-Lock lever makes it easy to lock or unlock the module(s).
2. When installing additional modules, you will need to turn AC power off at the controller.
3. Rotate the Positive-Lock lever on the module clockwise to the unlock position.
4. The module needs to be inserted into the next sequential position in the back of the controller. Note: If you are using a 4-station module, it must be in the last sequential position on the controller. Example: For an area that needs 12 stations, the first module will be an 8-station and the 4-station module will be below it. Note that station numbers are identified on the back panel, not the individual modules.
5. Insert the module into the controller’s expansion slot with the tab end first (opposite side with the Positive-Lock lever).
6. Push the module into the expansion slot and rotate the lever counter-clockwise (until the lever is flush with the side the module) to lock the module in place.
7. Restore 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 Positive-Lock feature was added to ICM modules date coded 12/02 or newer. The modules will also work with older ICC units.
