Faults with Auto-Restart
WARNING: Load may restart automatically without warning when operating conditions
permit. Disconnect power before servicing the convertor or connected loads.
The factory default allows auto restarts for noncritical faults. Disable restarts by setting DIP
switch 2, see Figure 16, to the
ON position.
After non-critical faults clear, the converter will automatically restart after a minimum 60
second delay. The LCD screen displays the auto restart count down. Cycle input power to
abort the restart delay and manually restart the converter. If an Auto Restart Fault repeats
10 times, the 11
th
occurrence becomes a manual restart event.

– Fault Codes
Text Description/Comments Restart
OUTPUT FAULT
Check for short circuit on output lines and load.
Contact Phase Technologies.
Manual
INPUT FAULT
Check for short circuit on input lines. Contact Phase
Technologies.
Manual
OVER TEMPERATURE
Internal temperature of the converter exceeded safe
operating limits. Check fans and ventilation openings
for obstruction. Reduce ambient temperature.
Auto
BUS OVERVOLTAGE
Sudden and severe regenerative power under high
line voltage may result in bus overvoltage.
Auto
HALL SENSE HIGH
Current exceeded the maximum rating of the Hall
sensor. May indicate a fault in the motor circuit.
Auto
LOW INPUT VOLT Input voltage has fallen below a safe operating level. Auto
CLASS 4 OVERLOAD Output current exceeded operating limit. Auto
PLL FAULT Phase-Locked Loop. Check input frequency. Auto
INPUT OVERLOAD Input current exceeded the operating limit. Auto
TEMP SENSE FAULT
Temperature sensor on the heat sink has failed or its
cable is disconnected.
Manual
HIGH INPUT VOLT
Input voltage has exceeded a safe operating level.
Reduce input voltage.
Auto
OUTPUT OVERLOAD
A large and sudden overcurrent event on the output
module. Check motor circuit for faults.
Auto
PRECHARGE FAIL
Pre-charge circuit has failed to charge bus
capacitors.
Manual
LINE CAP FAIL
Replace line capacitors or contact Phase
Technologies for replacement.
Manual
UNBALANCE BUS VOL
Potential damage to a bus capacitor or degradation
of the bus balancing resistor.
Auto
CM BOARD FAULT
Connection from Control board to Hall Sensor isn’t
properly connected. Power down unit, reconnect, and
restart.
