TROUBLESHOOTING GUIDE
General Problem
Voltage Cable
Fault (UC)
Boot Fault (bF)
CP-13-06-R5 (09/2018)
Possible Cause
The Voltage Feedback Fault indicates
the cascade drive signal is not present.
It typically occurs when high voltage is
triggered.
The Boot Fault indicates that an active
trigger signal was detected during the
start-up sequence.
Turn off the voltage controller and remove the high
voltage cable from the voltage controller.
Turn on the power and place HV test jumper J8 in
shorted position. If the UC fault occurs, send the
high voltage controller in for repair. If no fault occurs,
continue.
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.
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, indicating 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 measurement must be 150 to 170
Mega ohms. Replace resistor tube if the reading is
not correct.
Replace high voltage cable or send applicator unit
in for repair.
Turn off the voltage controller.
Ensure J8 HV test jumper on PC board is not shorting
both posts.
Ensure that the gun trigger is not pressed so the
trigger input signal is not active.
Turn on the voltage controller to verify that a trigger
signal is not present and that the unit enters the
'ready' state.
Send the voltage controller in for repair or contact
technical support.
