LEDs Condition
ACF [ac Fail]: Rectifier input is missing or out of range.
Correct ac fault.
In F [Input Fail]: Re-labeled LED on converter indicates
Converter input is out of range. Correct converter input fault.
Shutdown
∗: The unit cannot deliver output.
• High Voltage Shutdown
• Thermal Shutdown
• Under Voltage Protect
• Component failure
1. Check rectifier or converter status on controller display to
determine cause of shutdown
2. Correct system output short, high temp, etc.
3. Remove and reinsert unit. If fault remains and other units are
functioning correctly, replace unit.
Communication Fail: Blinks to indicate the rectifier is not
communicating with a system controller.
Remove and reinsert unit. If fault remains and other units are
communicating correctly, replace unit.
∗ When a power unit senses an over- or under-voltage condition it will shutdown, wait 10
seconds, and then attempt to restart. If the over- or under-voltage condition remains it
will cycle again. If the rectifier is loaded more than 10%, after 3 restart attempts the
unit will lock out, and user intervention is required to restart.
