4.4 Rectifier System Operation
① Check that each RM ON LED is illuminated (GREEN) for normal operation.
If the RM FAIL LED is on (RED), check module error status then remove
and reinsert the RM to check the status again.
② Verify that the RM ON LED is illuminated (GREEN) for normal operation.
If the FAIL LED is still on (RED), check the alarm displayed on the Control Unit LCD.
If any error on the rectifier system is not solved under the direction of above Table 3-1,
contact a Sales Representative or the headquarters of Dongah Elecomm.
4.5 Rectifier Removal / Replacement
① The Rectifier Modules are hot-swappable so can be replaced with AC power applied.
(Note that if any external battery has been connected, the Control Unit still operates.)
②
The Control Unit is not hot-swappable so replacement requires that the AC input
voltage be turned off and all external batteries be disconnected (BATT circuit
breakers OFF). Then the Control Unit can be replaced and the system power
restored.
4.6 Rectifier Module Restart
If a Rectifier Module output voltage is suspended due to a DC OverVoltage (OV),
manually turn off the main AC Circuit Breaker. Then, when the module is fully
discharged (LED off), turn on the AC Circuit Breaker to see if the event was isolated
or recurring. If the OV condition is not recovered, replace the Rectifier Module and
repeat this restart process to check that the replacement module clears the alarm.
