Tank Valve & LPG Level Sender Select Relays (W/Dual LPG Option)

TANK VALVE SELECT RELAY AND LPG LEVEL SENDER SELECT RELAY (W/DUAL LPG TANK OPTION ONLY)
The tank valve select relay and the LPG level sender select relay are controlled simultaneously and are used to toggle power to either LPG tank one or to LPG tank two when the ALT fuel system is in operation. Both relays default power to LPG tank one until the dual ALT/GAS switch is in the secondary ALT position. The ALT/GAS switch then provides power to energize both relay coils. When the relay coils are energized power is disconnected from LPG tank one and switched to LPG tank two. The tank valve select relay toggles system power between the LPG tank lock off valve while the LPG level sender select relay toggles between the LPG tank fuel level sender return circuits connecting one or the other to the Compuvalve input.
