Faults: Manual Restart

These faults generally indicate damage to the converter and/or the load. They may also
indicate a potentially dangerous condition. When this type of fault occurs, the display will
indicate the fault message and the converter output will remain off.
CAUTION! Contact Phase Technologies for assistance before restarting or
troubleshoot the system thoroughly before power cycling the converter.

Fault Log

The Fault Log records faults with number of occurrences. To access the Fault Log, set
SW3 and SW4 per Table 22. There are two fault logs – Master and User Fault Log.
Master Fault Log:
A non-resettable count of all faults over the life of the main circuit board
User Fault Log:
A resettable count of faults. Each fault type is limited to a count of 10. On the 11
fault, the unit will display the appropriate fault and the LCD screen will display
"RESET? PWR CYCLE".
Power cycling the unit will reset the fault back to zero.
Description/Comments
Check for short circuit on input and output lines and
load. Contact Phase Technologies.
Input current exceeded the operating limit.
Replace line capacitors or contact Phase
Technologies for replacement.
Input voltage has fallen below a safe operating level.
A large and sudden overcurrent event on the output
module. Check motor circuit for faults.
Internal temperature of the converter exceeded safe
operating limits. Check fans and ventilation openings
for obstruction. Reduce ambient temperature.
Phase-Locked Loop occurs when input frequency is ±
7 Hz of 60 Hz. Check input frequency.
Pre-charge circuit has failed to charge bus
capacitors.
PT420 and PTE420QT only. Temperature sensor
near inductor has exceed safe operating limits. Wait
for temperature to drop to safe level.
Temperature sensor on the heat sink has failed or its
cable is disconnected.
Potential damage to a bus capacitor or degradation
of the bus balancing resistor.
Output voltage difference between pass-through legs
and generated leg is greater than 50 V.
