Figure 17. Main Inputs Wiring
GENERAL NOTE: ICS highly recommends using shielded cable for all input wiring. Terminate the shield
drain on the ground lug provided in the controller. Jumpers for each input must be set to external
voltage 24 V AC.
NOTE 1: Optimally, the roller locator switch should be wired normally closed to the ICS controller.
Wiring the roller locator switch normally open is acceptable but will mean waiting longer for the roller
to fire.
