Troubleshooting
1. Power supply “Power On” light not illuminated when the power switch is in the “ON” position. Check that all
safeties are closed and there is primary power applied to the power supply. If light will still not illuminate,
remove power and energize after five minutes. The GPS-iMOD system uses an internal auto-reset circuit
breaker. Either a voltage surge or high temperature/load condition can trip the circuit breaker. If the “Power
On” light is off and the “Plasma On” light is “On,” the “Power On” light may have burned out. Contact your
local Representative or the GPS factory to have your power supply repaired or replaced.
2. No Ionization Output.
Confirm the power supply is operating properly per step 1A above. Confirm the HV cables are inserted and
secured properly. Confirm the needles are clean and free of debris.
