These jumpers couple the relays to different input signals and enable separate control of the circuits connected to them. If these jumpers are set to the "ON" position, the relays are controlled by the microprocessor on the circuit board through either the "P" or "E" input terminals depending on DIP switch 6 setting in the CCRP. If Jumper 8 (J8) is in the "OFF" position, relays 7, 8, and 9 respond only to the OV4 input terminal. If Jumper 9 (J9) is in the "OFF" position, relay 1 responds only to the OV1 input terminal; relay 2 responds only to the OV2 input terminal; and relay 3 responds only to the OV3 input terminal.
Depending upon how the controllable devices are field wired into the circuit board, the positions of J8 and J9 jumpers, and DIP switch 6 setting, it is possible to have the CCRP provide individual load control for up to 6 separate control strategies. If utilizing multiple control strategies, refer to DIP Switch Settings description, the Relay Triggering Schematic, and the Example System Wiring Diagram for Multiple Strategies.
