Solenoid Output Connections, Ignitor 1 and 2
The solenoid output connections are designed for driving external solenoid valves. Each output is rated for a maximum of 3A
of steady-state current output. The main input voltage (either 12VDC or 24VDC) is fused and then directed through solid-state
relays which controls this voltage output to each solenoid terminal. The solid-state relays are able to detect direct shorts and
elevated current levels on solenoid outputs and shut down the affected solenoid outputs.
Note: All solenoid outputs can be configured to use separate Low Power Solenoid settings. Therefore, the setting for each
solenoid output must be verified to work with the attached solenoid. Larger solenoids with higher power requirements will
need to be set to a higher setting (40% or 50%) to remain open when desired. Smaller solenoids (Pilot valves) should be able
to work on a setting down to 10% - 20%. A lower solenoid driver setting means more power savings.
The solenoid output connections are matched with their corresponding Ignition module, as shown in the following table:
