Error Messages & Troubleshooting
Display Error Message Error Description User Troubleshooting
Power Loss Error Power loss during pulsing. Power lost while protocol was running.
PFC Over Temp Pfc module over temperature. Hardware error. Please contact the manufacturer.
Interlock Open Electrode interlock open. Connect electrode connectors to the front of the generator and make sure the
cuvett safety dome cover is closed.
IGBT Switch Fault IGBT switches fault. Hardware error. Please contact the manufacturer.
Charge Voltage Max Error Charging voltage above the expected voltage. Turn off the unit for a few minutes then turn back on. Re-run the protocol if the
issue recurs, contact the manufacturer.
Charge Current Max Error Charging current above the expected current. Turn off the unit for a few minutes then turn back on. Re-run the protocol if the
issue recurs, contact the manufacturer.
LV Cap Bank Max Low voltage capacitor bank voltage above expected value. Turn off the unit for a few minutes then turn back on. Re-run the protocol if the
issue recurs, contact the manufacturer.
LV Cap Bank Min Low voltage capacitor bank voltage below expected value. Turn off the unit for a few minutes then turn back on. Re-run the protocol if the
issue recurs, contact the manufacturer.
HV Cap Bank Max High voltage capacitor bank voltage above expected value. Turn off the unit for a few minutes then turn back on. Re-run the protocol if the
issue recurs, contact the manufacturer.
HV Cap Bank Min High voltage capacitor bank voltage below expected value. Turn off the unit for a few minutes then turn back on. Re-run the protocol if the
issue recurs, contact the manufacturer.
Charge Time Max Charging capacitor bank to selected voltage exceeded max time estimated. Turn off the unit for a few minutes then turn back on. Re-run the protocol if the
issue recurs, contact the manufacturer.
Pulse Droop Error Pulse voltage droop exceeded estimated droop. A) Increase the sample resistance. This can be achived by:
1. Increasing the gap size
2. Reducing the volume
3. Use a less conductive buffer
B) Reduce the pulse duration
Pulse Voltage Overshoot Pulse voltage monitor (p-vmon) pulse overshoot. Hardware error. Please contact the manufacturer
Pulse Voltage Mon too Low Pulse voltage monitor (p-vmon) below min voltage. Hardware error. Please contact the manufacturer
Pulse Voltage Mon too High Pulse voltage monitor (p-vmon) above max voltage. Hardware error. Please contact the manufacturer
Pulse Current Mon too Low Pulse current monitor (p-imon) below min current. Hardware error. Please contact the manufacturer
Pulse Current Mon too High Pulse current monitor (p-imon) above max current. Hardware error. Please contact the manufacturer
Arc_Detected Arc detected during pulsing. Arc could happen due to the one or more of the following conditions:
1. Sample resistance is very low for the voltage selected
2. Gap size is too small for the voltage selected
3. Pulse duration is too long
No_HB_from_GUI Communication error. Hardware error. Please contact the manufacturer
Sample Resistance
Out Of Range
The measured sample load is out of range. Increase the sample resistance. This can be achived by
1. Increasing the gap size
2. Reducing the volume
3. Replace the buffer with less conductive type of buffer
Over Current Pulse Abort Pulse aborted due to pulse over current. The over current protection feature is added to prevent sample arcing.
This could occur when the sample resistance changes during the pulse:
1. Sample resistance is very low for the voltage selected
2. Gap size is too small for the voltage selected
3. Pulse duration is too long
Idle V I Max Voltage or current in idle state is higher than expected. Turn off the unit for a few minutes then turn back on. Re-run the protocol if the
issue recurs, contact the manufacturer
Charge Cap Bank A Max Charge capacitor bank A voltage is above tolerance. Turn off the unit for a few minutes then turn back on. Re-run the protocol if the
issue recurs, contact the manufacturer
Charge Cap Bank A Min Charge capacitor bank A voltage is below tolerance. Turn off the unit for a few minutes then turn back on. Re-run the protocol if the
issue recurs, contact the manufacturer
Charge Cap Bank B Max Charge capacitor bank B voltage is above tolerance. Turn off the unit for a few minutes then turn back on. Re-run the protocol if the
issue recurs, contact the manufacturer
Charge Cap Bank B Min Charge capacitor bank B voltage is below tolerance. Turn off the unit for a few minutes then turn back on. Re-run the protocol if the
issue recurs, contact the manufacturer
Charge Cap Bank C Max Charge capacitor bank C voltage is above tolerance. Turn off the unit for a few minutes then turn back on. Re-run the protocol if the
issue recurs, contact the manufacturer
Charge Cap Bank C Min Charge capacitor bank C voltage is below tolerance. Turn off the unit for a few minutes then turn back on. Re-run the protocol if the
issue recurs, contact the manufacturer
Dump Time Max The capacitor bank did not fully discharge in the estimated time. Turn off the unit for a few minutes then turn back on. Re-run the protocol if the
issue recurs, contact the manufacturer
Invalid Protocol The generator was requested to run an invalid protocol. Verify that the used protocol is within the allowed specifications of the generator
System Processing (Busy) The control command is invalid or was issued while the generator was busy. Allow more time between events
TC_Error The measured rc time while delivering an exponential decay pulse is invalid. Hardware error. Please contact the manufacturer
Pulse Duration Error The pulse duration did not meet the expected duration. Hardware error. Please contact the manufacturer
Unit Type Sel Error The unit hardware and software do not match the corect type. Hardware error. Please contact the manufacturer
Error: 0X# Multiple errors. Multiple error. Please contact the manufacturer
