Tyco Electronics Galaxy SC Controller J85501F-1
5 - 10 Acceptance Testing Issue 13 February 2001
• Upon the fourth shutdown, the rectifier’s ALM LED lights and
the rectifier’s display indicates “HO.”
• Any external RFA and BD office alarms have occurred.
6. The controller will wait 5-6 minutes and issue one final restart
signal initiating the final sequence of shutdown and restart events
before the rectifier locks out, requiring personnel intervention.
Prior to this occurring do the following:
a. From the Front Panel follow the path <MENU> → CONFIG →
RECT MNGR → PLANT V (FLOAT) (Basic controller) or
<MENU> → CONFIG Æ RECT MNGR → RECT OPER →
PLANT V (FLOAT) (Intelligent controller).
b. Use the <ADJUST> keys to change the value of the plant
voltage to it's normal level. Press ENTER to save the change.
c. Press <MENU> and select MAINT OPER → REC RST. Press
<ENTER> to restart the rectifier. Restore the serial cable plug
disconnected in the beginning of the procedure.
Note: Restarting the rectifier from the Front Panel in this manner, rather
than toggling the rectifier's ON/STNDBY switch, resets the HVSD
timer so that another rectifier can be tested immediately. Testing of the
additional rectifiers in the same manner is at the user’s discretion.
Battery on
Discharge
Alarm
If the BD alarm was observed during the High Voltage Shutdown test
this test can be disregarded. Otherwise, test as follows:
1. From the front panel follow the path <MENU> → CONFIG →
THRLD and observe the setting of the BD (FLOAT) threshold.
1. With a dummy load added to the plant, operate all rectifiers to
STDBY until the plant voltage drops below the BD (FLOAT)
threshold. Observe the active BD and MAJ LEDs and asserted
PMJ and BD relays.
2. Restart the rectifiers to retire alarms and return the plant voltage to
float.
Rectifier Fail
Alarm
Introduction: If the RFA alarm was observed during the High Voltage
Shutdown Test no separate test is required. If the High Voltage
Shutdown Test is not performed, generate an RFA (Rectifier Fail Alarm)
in each of the plant rectifiers individually, using the procedures below:
