Hotline FAQ: SubDrive/MonoDrive

Franklin’s SubDrive and MonoDrive systems have both red and green lights.  What do they do?

The green light is the power light.  When green is on steady, it means the unit has electricity and is waiting to run.  Not unlike sitting on the sidelines waiting to play in the big game.  Once the pump and motor are activated, the green light begins to blink.  A blinking green light tells you everything is “good” and your system is running.  When the red light is on, it means the SubDrive or MonoDrive has found something it does not like.  It is like the “check engine” light on your car.  While it may continue to operate, the red light means something is not quite right and your system is calling for help.
