output. For these applications the contactor may be wired
directly to the control output of the BUJ board. The installation
of this circuitry is covered in the appropriate plant product
manual. These connections are typically factory wired. If the
controller is to be wired in the field, the following connections
should be made to the external LVD contactor from the alarm
terminal board.

LVD1_ST(ate) TB3.4 J13-2 A closure between this signal and LVD1_RTN or bat, signals the
Vector controller the Contactor is OPEN.
LVD1_RTN TB3.5 J13-1 Return for LVD1_ST
LVD1_CON1 TB3.6 J13-3 Provides on side of a contact closure for contactor coil operation
LVD1_CON2 TB3.7 J13-4 Provides second side of a contact closure for contactor coil operation
LVD2_ST(ate) TB3.9 J14-2 A closure between this signal and LVD1_RTN or bat, signals the
Vector controller the Contactor is OPEN.
LVD2_RTN TB3.10 J14-1 Return for LVD1_ST
LVD2_CON1 TB3.11 J14-3 Provides on side of a contact closure for contactor coil operation
LVD2_CON2 TB3.12 J14-4 Provides second side of a contact closure for contactor coil operation
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 BUJ1 temperature ports as
shown in Figure 2-5. The installation of this equipment is
