troubleshooting

The Plasma Gas Box has two visible LEDs that indicate its' status. When the GREEN LED is on, this indicates power
is applied to the unit and the rate at which it is flashing shows the operational status of the unit (refer to the chart
below). If the Green LED is not ON, check the power cable, which should carry 24VDC and 24VAC from the Shield
Gas Box.
If the Yellow LED is not ON, either there is no power to the unit or the station is not selected.
The Plasma Gas Box is highly integrated and is treated as a "Black Box". If one or more functions of the unit stop
working, the unit must be returned for repair. Contact technical support for troubleshooting and RMA assis-
tance.
