Rectifiers/Converters
Status of a rectifiers and converters is provided by LEDs on their faces, and by extensive real time data, alarm and
event history accessible through the system controller.
Figure 80 Rectifier Face Plate
Non-Eco rectifiers powered by PV (solar) panels will not operate properly.
• Under some conditions their LEDs may indicate normally operation: Norm LED ON.
• Various other LED conditions and rectifier status (observed via the controller) may occur with variations in
DC input and load.
Rectifier/Converter Troubleshooting
1. Verify rectifier positions per the procedure in the Verify Rectifier Positions section.
2. Observe and compare Rectifier/Converter Status LEDs with Controller Status information.
3. Use the table below as a troubleshooting guide.

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
