Tyco Electronics Galaxy SC Controller J85501F-1
7 - 33 Feature Descriptions Issue 13 February 2001
Bay input circuit breaker
Bay temperature
Configuration of this feature involves linking remote peripheral
monitoring channels and use-defined events to the rectifier bay.
Rectifier Off
Conditions
The rectifier may experience one or more of the following OFF
conditions:
• MAN: the rectifier is turned off from its front panel or has lost
power
• STCB: the Switch-mode rectifier is turned off from it front panel or
the rectifier has its output circuit breaker in the off position.
• ACF: the rectifier is reporting an AC failure or the Galaxy SC is
assuming that since all rectifiers are off, that there is an AC failure.
• RFA: the rectifier is reporting a Rectifier Failure Alarm (RFA)
condition
• RFA-HV: the rectifier is reporting an RFA due to a high voltage
condition.
• RFA-CB: the rectifier is reporting an RFA due to a circuit breaker
failure.
• RFA-TA: the rectifier is reporting an RFA due to insufficient
airflow or excessive ambient temperature.
• PH: on non full 3-phase rectifiers, a phase (or limited output) alarm
indicates that the rectifier has lost all power.
Rectifier Standby
Conditions
The rectifier may experience one or more of the following STANDBY
conditions:
• TERM: the operator has placed the rectifier in reserve
• EMS: the energy management routine has placed the rectifier in
reserve
• PH: the full 3-phase rectifier, has a phase alarm, and because of
this, the Galaxy SC temporarily places the rectifier in reserve until
10:00 am the following morning or until a battery on discharge
alarm occurs, whichever condition is earlier. A full 3-phase rectifier
with a phase alarm, will continue to operate but not at its rated
capacity.
• ETR: the rectifier is not used in internal rectifier sequencing or the
ETR signal is still active
• TR: the rectifier is placed in standby by the external rectifier
sequencer via TR1, TR2, TR3 or TR4
• CB: The rectifier is reporting a circuit breaker failure, however the
rectifier does not turn itself off. This occurs on Tyco Electronics
