Tyco Electronics Galaxy SC Controller J85501F-1
5 - 6 Acceptance Testing Issue 13 February 2001
• When the voltage increases to the HV (FLOAT) level the
rectifier shuts down.
• The Green ON LED on the rectifier blinks, the ALM LED on
the rectifier is not lit.
• After 5-6 seconds the rectifier initiates its own restart signal
again, raising the plant voltage.
• The rectifier will shutdown and restart three additional times.
• Upon the fourth shutdown, the rectifier's ALM LED lights and
the rectifier's display indicates “HO.”
• The controller receives the RFA signal from the rectifier and
initiates a restart signal 5-6 seconds later.
• The rectifier restarts again, raising plant voltage.
• The rectifier shuts down and restarts four additional times.
• During these shutdowns the Green ON LED on the rectifier
blinks, the ALM LED on the rectifier is not lit.
• Upon the fourth shutdown, the rectifier's ALM LED lights and
the rectifier's display indicates “HO.”
• An external RFA office alarm is generated.
7. 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 → RECT MNGR → RECT OPER →
PLANT V (FLOAT) (Intelligent controller).
b.
Use the <ADJUST> keys to change the va
lue of the plant
voltage to its normal level. Press <ENTER> to save the change.
c. Press <MENU> → MAINT OPER and select RECT RST. Press
<ENTER> to restart the rectifier. Note: Restarting the rectifier
from the front panel in this manner, rather than toggling the
rectifier’s ON/STANDBY 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.
