Tyco Electronics Galaxy SC Controller J85501F-1
4 - 50 Configuration Issue 13 February 2001
Alarm Test Configure → Alarms Test. Individually configures each of the
controllers alarm relays for operation during an alarm test. Alarm Test
and Remote Alarm Test are enabled in software at Configure → DC Plt
→ Hardware & Software Configured. The hardware switch for Alarm
Test is SW202-5 on the BJB pack. The Hardware switch for Remote
Alarm Test is SW204-2 on the BJH pack. Each individual relay can be
enabled or disabled for the test. Other configurable items are:
DES: Allows modification of the default designation of this feature.
Duration: Sets the time each successive relay will operate between 5
seconds and 300 seconds (5 minutes).
Battery Bay Configure → Battery Mgmt → Battery Bay. The user must add the
Battery Bay to the system and then modify it. Once added the
description can be changed and a link added to RPM channel assigned
to monitor the temperature in the battery bay. The Battery Bay may also
be associated with any Battery Section that has been configured.
Contactor 1
Contactor 2
Contactor 3
Configure → Battery Mgmt → Contactor 1 / Contactor 2. The
controller can support two optional contactors that are controlled
through system software and the UR1 and UR2 relays. The following
are configuration parameters.
Configure → Battery Mgmt → Contactor 1 / Contactor 2 /
Contactor 3. Up to 3 optional LVD devices can be connected to a
Galaxy SC and configured from this path. For plants without any BIC
card located on a GPS serial rectifier bay, LVD control is obtained via
wiring off the UR1 (Contactor 1), UR2 (Contactor 2), or VLV/UR3
(Contactor 3) relays on TB2/3 of the BJT card on the rear of Galaxy SC.
These relays cannot be configured for use as alarm relays if used for
LVD contactor control. A “URC” User Relay Conflict alarm will
activate if contactor programming from this screen is attempted for a
user relay that already has an alarm assigned to it or vice versa.
As soon as any BIC card is connected to a serial rectifier bus, the user
relays are released from their use for LVD contactor control and this
function is transferred to the LVD control circuits of all BIC cards in the
plant. Please note that in a standard GPS configuration using BIC cards,
Contactor 1 is wired to and controls all BATTERY contactors in the
plant, while Contactor 2 and Contactor 3 are wired to and control only
LOAD contactors.
DES: Allows modification of the default designation.
