Tyco Electronics Galaxy SC Controller J85501F-1
3 - 28 Installation Issue 13 February 2001
3. Locate the ED-83009 circuit pack in the right-hand side of the
controller. Toggle the EFF/DIS switch to the upward (Disabled)
position. Plant Eff Status and System Alarm LEDS in the MCS
will activate. Verify that All rectifiers are turned on before
proceeding. If the controller does not operate as expected, stop and
correct the problem before proceeding.
4. Identify the power converter pack ED-83011 or ED-83010 in the
leftmost position of the right-hand card cage. Pull down on the
locking lever of the converter to power down the converter.
5. If there is a second converter pack in the left-hand card cage, pull
down on the locking lever of the converter to power down the
converter.

Caution: When the rectifier regulation fuse is pulled, the rectifier will
switch to internal regulation and the plant voltage will increase. This
will require a re-adjustment of the rectifier output volt adjust
potentiometer as detailed in various steps below.
1. Observe and note the current on a rectifier.
2. Operate the Power ON/OFF switch on a rectifier to OFF.
3. Operate the DC OUTPUT breaker to OFF.
4. Remove the associated rectifier regulation fuse (F1 to F16) from
the controller.
5. Remove the rectifier control cable from the controller backplane
and mark or tag it.
6. Turn the rectifier Power switch to ON. The green Power LED
must light. Wait 10 seconds. Verify the rectifier output voltage is
approximately battery voltage, typically 52/26 volts, by holding
the rectifier meter select switch in the RECT-V position. For
rectifiers not equipped with a digital meter, verify the output by
measuring the rectifier regulation test jacks with a DVM.
7. Turn the rectifier Power switch OFF. Within 10 seconds, turn the
DC circuit breaker ON then turn ON the rectifier power switch.
Readjust the rectifier output volt adjust potentiometer to obtain
approximately the same current observed previously at the
beginning of the procedure.
