The remote light driver is waterproof and has dimensions of 4 inches high by 2.75 inches wide by 1 inch deep. An output signal from the primary display module is input to the remote light driver. This provides the option to power four (4) 60 watt remote lights that show the volume of liquid in the tank. The lights will show full, 3/4, 1/2, and 1/4 tank levels.
When power is applied the remote light driver runs a lamp test function. The lamp test starts at the 1/4 light and cycles each remote light on and off. At the completion of the lamp test the remote light driver turns on the correct light(s) to show the tank water or foam volume.
All four lights are on when the tank is full. The top light goes off as the tank starts to empty (at 7/8 full the light is off). The three bottom lights are on to show that the tank is between less than full (approx. 7/8 tank) and 1/2 tank. The bottom two lights show 1/2 and 1/4 tank. The bottom light blinks when the tank volume goes less than 1/4 tank.
