Tyco Electronics Galaxy SC Controller J85501F-1
Issue 13 February 2001 Acceptance Testing 5 - 5
2. The rectifier must be delivering a current exceeding 10% of its
capacity.
3. The rectifier’s current output must be unbalanced by more than
10% from the average output currents of the other rectifiers.
Because item 3 is difficult to achieve in a simulation test of
properly functioning serial rectifiers (even with load share
disabled), rectifiers are tested one at a time, rather than as a group.
Slightly different test procedures are used for special applications
in batteryless plants.
Serial rectifiers have their own internal restart circuits which will
function 3 times before the rectifier locks itself out and initiates a High
Output Rectifier Fail Alarm to the controller. If there is to sufficient
interval between these between restart and a subsequent shutdown the
rectifier resets its restart counter.
The controller initiates a restart signal a few seconds after the first RFA
(HO) alarm is received. After the second RFA (HO) is received, the
controller waits 5 minutes before sending one additional restart signal.
1. Verify the Auto Restart hardware switch at SW202-7 on the BJB
pack is set to 1 (Enabled). Verify the software switch for the Auto
Restart feature is enabled from the Front Panel path MAIN →
CONFIG → PLANT → AUTO RST (Basic controller) or MAIN
→ CONFIG → RECT MNGR → RECT CNTRL → AUTO RST
(Intelligent controller).
2. Turn Off all rectifiers except the rectifier under test by operating
their power switches to STANDBY. Ensure that the system is
loaded to 10-30% 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 controllers) from the Configuration screen.
5.
Use the <ADJUST> keys to change the va
lue of the plant voltage
to a level above the HV (FLOAT) setting noted in Step 3. Press
<ENTER> to save the change.
6. Observe the following:
