NOTE: J3, J7, J8 & J11 inputs (max source current of 25mA) are all connected to dry
terminals (NC, NO) with a common connection to the Ground terminal on each of
the connectors; dry terminals must be able to sink minimum 25mA at a minimum of
5V rating. J1 is rated for an output of 12V @ 200mA.

If SW4 is in the OFF position when the bypass switches (SW1 and SW3) are "OFF", then GREEN LEDs are "OFF" & Controller Board
can activate the relays
If SW4 is in the ON position when the bypass switches (SW1 and SW3) are "ON", then relays are bypassed & GREEN LEDs are "OFF"
If SW4 is in the ON position when the bypass switches (SW1 and SW3) are "OFF", then GREEN LEDs are "ON" & Controller Board
can activate the relays
If SW4 is in the OFF position when the bypass switches (SW1 and SW3) are "ON", then relays are bypassed & GREEN LEDs are "ON"
NOTE: Boards are shipped with SW4 in the OFF position with tape seal

• Relay Switch SW4 determines the
idle state of the Relays after a power
up and when the System is ON.
• The table below describes the
terminals after power up and during
IDLE state with the bypass switches
(SW1 and SW3) OFF.
