Troubleshooting NE-Series Rectifiers/Converters
The status of an NE-Series rectifier or converter is provided by LEDs on their face, and
by extensive real time data, alarm and event history accessible through the system
controller.
Rectifier/Converter Status LEDs
LEDs Condition
Normal operation: No alarms, inputs and outputs are in their
normal range, communicating with the system controller.
Unpowered: No input or output voltage present.
1. Remove and reinsert unit.
2. Check input voltage with a voltmeter,
if input voltage is present, replace unit.
3. Check output bus voltage with a voltmeter,
if output bus voltage is present, replace unit.
Standby: The unit is okay, but has been placed in Standby by the
controller and is not delivering power.
Note: If a unit in standby loses communications with the controller
it will exit Standby mode and deliver power
Output Limit: The unit is okay and delivering maximum output
• At max rated output
• At configured current limit
• At thermal limit
If rectifiers/converters are equipped with optional air filters and
reporting thermal limiting, check air filters. Clean or replace all
filters if necessary.
