Galaxy Vector Controller GCM2, GCM3

4 - 2 Installation and Configuration

Issue 4 January 2008

Load Disconnect must be completed. The installation of this
circuitry is covered in the appropriate plant product manual.
These connections are typically factory wired.

If the plant batteries are the sealed or maintenance free valve-
regulated type, Battery Thermal Compensation may be used.
This feature requires 10K ohm thermistor devices. The Vector
controller can monitor up to four temperatures. If more than four
devices are needed, a 210E thermistor multiplexer may be used.
The 210E is then wired into the BLJ3 or BTJ2/BTJ3 temperature
ports as shown in Figure 2-6 or 2-7. The installation of this
equipment is covered in its respective product manual. These
connections may be factory or field wired.

Thermistor input and alarm connections for the 210E thermistor
multiplexer unit are shown in Figure 4-1 (BLJ3 board), and
Figures 4-2a and 4-2b (BTJ2/BTJ3 board).

The Vector performs rectifier sequencing based on the state of
the ACF alarms from the rectifiers and Rectifier RO (Reserve
Operation) engine signal terminated at the BLJ3 RO terminal. If
this feature is to be used, complete this wiring as described in
Section 3.
