Galaxy Rack-Mounted Vector Controller J85501M-1
2 - 10 Product Description Issue 2 January 2008
LVD1, LVD2 Relay contact outputs for LVD contactor control. Contacts are
rated for 10 amps. Power must be provided externally to the
contactor coil. The contactor coil should have battery
permanently attached. The LVD1 and LVD2 contacts should
complete the circuit to DG. This power is switched by the LVD
control contact closure provided.

Office Alarm Relay
Outputs
All alarm output relays are isolated Form C or transfer type
contacts, consisting of Open (O) and Closed (C) contacts, with a
common Return (R(C)) contact. The de-energized state of the
controller forces these contacts to the alarm state. An alarm
condition results in a closure of the Closed contact to the Return
contact, and an open between the Open and Return contacts.

1. C: Open contacts. Closed to R(C) when alarm condition exists.
R(C): Return (common)
O: Closed contacts. Open to R(C) when alarm condition exists.
2. Relay assignment is determined by the settings of S1.2 and S1.5:
HV alarm S1.2-0, S1.5=0
2ACF alarm S1.2=1, S1.5=0
VLV alarm S1.2=0, S1.5=1
Setting both switches to 1 results in activating HV. The S1.2 setting is only read during
GCM power up.
Auxiliary Battery
Supply (ABS)
Auxiliary Battery Supply (ABS) is connected to the battery
discharge bus and fused through F1 (1-1/3A) for user application
on TB4 pins 1, 3, 5, 9, and 11, and TB5 pin 1. F1 is field
replaceable.
