PROTECTION, ALARM AND CONTROL SYSTEMS
Rectifier Failure Alarm (RFA)
Problems occurring because of an unacceptable relation-
ship between the output power and load conditions will
cause a Rectifier Failure Alarm (RFA). This alarm consists
of a red LED and a flashing green OK LED. Conditions
which may lead to an RFA are:
Low Current - Output current has decreased to below
5% of its rated value.
Unit Shutdown - Any shutdown occurrence due to
overvoltage, external shutdown command, unacceptable
ambient temperature conditions or low AC input voltage.
Load Sharing Terminal Pin Out Of Range - The
terminal pin is out of range.
Remote Control Terminal Out Of Range - The remote
control terminal pins are out of range.
Line Sag - This condition occurs when the nominal
voltage decreases below 180V. Normal range is 208-
240V.
Fan Malfunction - The fan has stopped operating or is
not providing the airflow needed to cool the unit.
Over Temperature - The ambient temperature has
exceeded 65°C.
High Voltage Shutdown (HVSD)
The unit’s built-in high voltage limit is permanently set at
60V. When internal shutdown occurs, the unit may be
restarted by a local switch or by a remote signal.
Surge Protection
The unit will withstand lightning and input surges of
6000V/3000A.
Under Voltage Protection
When input voltage is below 105 VAC, the rectifier’s
operation is automatically power limited.
