Tyco Electronics Galaxy SC Controller J85501F-1
Issue 13 February 2001 Acceptance Testing 5 - 9
Batteryless Plant
HVSD Test (Serial
Rectifiers)
1. Turn off all but two rectifiers operating their power switches to
STDBY. In one of the rectifiers unplug its serial cable link to the
controller. In some rectifiers, the air flow shield above the rectifier
may need to be removed to access this plug. The ALM LED in the
rectifier will blink. The rectifier “remembers” the last voltage
control signal from the controller and will support plant voltage
during the test.
2. Adjust the dummy load to provide 10 to 30% of the rectifiers
output capacity.
3. From the Front Panel follow the path <MENU> → CONFIG →
THRESH and note the value of the HV (FLOAT) threshold.
4. Press the <ESC> key to return to the Configuration screen. Follow
the path RECT MNGR → PLANT V (FLOAT) (Basic controller)
or RECT MNGR → RECT OPER → PLANT V (FLOAT)
(Intelligent controller) from the Configuration screen. Use the
<ADJUST> keys to change the value of the plant voltage to a level
above the HV (FLOAT) setting noted above. Press ENTER to save
the change.
5. Observe the following:
• 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 two additional times.
• Upon the third 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 3 additional times.
• During these shutdowns the Green ON LED on the rectifier
blinks, the ALM LED on the rectifier is not lit.
