Fault Description Solution
Voltage Cable
Fault (UC) The Voltage Feedback Fault indi-
cates the cascade drive signal is
not present. It typically occurs
when high voltage is triggered. 1. Turn off the voltage controller and remove
the high voltage cable from the voltage con-
troller.
2. Turn on the power and place HV test jumper
J8 in shorted position. If the UC fault oc-
curs, send the high voltage controller in for
repair. If no fault occurs, continue.
3. Either the high voltage cable or if using a
hand gun, the gun resistor tube has failed..
If available, replace the high voltage cable,
or continue to test the resistor tube.
4. To test the resistor tube, remove the resistor
tube from the gun and inspect for signs of
burning or arcing. Cracks or black marks
indicate failure of the resistor tube, indicat-
ing the resistor tube must be replaced.
Measure the resistance using a tri-meter
connected to the black end of the tube and
screwdriver in the other end. The measure-
ment must be 150 to 170 Mega ohms. Re-
place resistor tube if the reading is not cor-
rect.
5. Replace high voltage cable or send applica-
tor unit in for repair.
Boot Fault (bF) The Boot Fault indicates that an
active trigger signal was detected
during the start-up sequence. 1. Turn off the voltage controller.
2. Ensure that the gun trigger is not pressed so
the trigger input signal is not active.
3. Turn on the voltage controller to verify that a
trigger signal is not present and that the unit
enters the ‘ready’ state.
4. Send the voltage controller in for repair or
contact technical support.
