8Contactor
Lights when contactor is energized. 9 Over Temp
Lights when contactor is energized and over temperature condition is present. Also indicates top cover is removed from unit.
10 Tank Current
Fault Value Preset At Factory 11 Ground Fault
Lights when the ground fault circuitry detects a short in the output circuit between the workpiece and power source, or when test switch is pressed to test ground fault circuitry.
12 Load
Lights when no load or insufficient load is present to couple with the coil or blanket.
