TROUBLESHOOTING GUIDE
General Problem Procedure Solution
Blank Display
Faults
1. If the display is blank on
initial power-up, it may be
that the display contrast is
not set correctly.
1. No Fault
2. Current Limit Fault
3. Max Output Fault
4. Min Output Fault
5. kV Limit Fault
6. dv/dt Fault
7. di/dt Fault
8. Voltage Cable Fault
9. Current Cable Fault
10. Low Voltage Fault
11. Hardware Fault
12. Communication Fault
1. Cycle the Power on the unit.
2. Within 5 seconds, press the SET button.
3. Press and hold the right arrow button until the
display contrast looks correct.
4. When the display contrast looks correct,
press the SET button again.
1. No Fault was detected.
2. The current value has exceeded the I Limit
Hi or the Max System Limit.
3. The system has raised the Variable Voltage
Output to the system maximum, but could not
reach the setpoint.
4. The system has lowered the Variable Voltage
Output to zero and still is above the setpoint.
5. The system has exceeded the kV Limit Hi or
the Max System Limit.
6. The system has detected a dv/dt event.
7. The system has detected a di/dt event.
8. The system has detected a loss of the High
Voltage Feedback signal.
9. The system has detected a loss of the Current
Feedback signal.
10. The system has fallen below the kV Limit
Lo in Current Mode.
11. The system has detected a fatal System
Failure.
12. The system has detected a communication
failure after an Ethernet IP connection was initi-
ated.
