Building
Control Module

The building control module (BC) consists of three (3) assemblies. The

I/O Building

Control Module

, the

Building Control Expander,

and the

Building Control

Display/Switch Module.

Building
Control
Circuit
Module

The building control module consists of eight (8) form A/B (jumper programmable)
10 amp relays set up in four (4) "ON" relays and four (4) "OFF" relays, with a 10 amp
fused common. Each relay (ON and OFF) is programmable for N/O or N/C contacts
by removing the A or B jumper. Remove the A jumper for N/C contacts or the B
jumper for N/O contacts. The module also provides four (4) feedback input points
(switched negative) using 3.9K ohm resistors in parallel with an open feedback
contact. A (-) connected directly to the feedback point will actuate the Red LED and a
(-) through the 3.9k resistor will actuate the Green LED. Should the feedback points
be connected the LED's on the building control display will follow the status of the
feedback input point.  Otherwise the LED's on the display will follow the status of the
active relay.  Programming jumper (S1) is provided on each board for setting the
vertical position/address of the card (S1-1 through S1-4). The building control
module uses the lower terminal block and cables to the bus driver module.  The
building control module uses one slot in the Module bus.

Building
Control
Expander

The building control expander module provides an additional eight (8) form A/B
(jumper programmable) 10 amp relays set up in four (4) "ON" relays and four (4)
"OFF" relays, with a 10 amp fused common. The module functions identically as the
building control module - providing four (4) feedback input points (switched negative)
using 3.9k ohm resistors in parallel with an open feedback contact. The expander
module mounts to the building control module (via standoffs) and uses the upper
terminal block and cables to the I/O building control module.

Building
Control
Display/Switch
Module

The control display module provides eight (8) red "OFF" relay activated LED's, eight
(8) green "ON" relay activated LED's. Eight (8) three (3) position (AUTO,ON,OFF)
rotary switches are provided for manual control of the I/O building control module
and building control expander. Eight (8) circuit tactile switches are provided for

programming

and

Bypass

functions. Card slots are provided for building control

description, comments. The building control display module mounts to the display
door and is cabled to the bus driver module. The physical location of the display is
set by the addressing jumper S1. Ensure addressing jumper is set according to its
physical location in the cabinet and matches associated I/O module address jumper
setting. Refer to Figure I-1, Cabinet Module Locations.
