SECTION 4: APPLICATION SPECIFIC
CARDS TERMINATION
4-1 UNIVERSAL SYSTEM CONTROLLER
The Universal Systems Controller (USC)
handles direct breaker control and status.
In addition to controlling breakers, the USC
has low voltage inputs and outputs which
can be used for switches, pilot lights,
photocells, dimmer ballasts, or other
external devices. The GHBS / BABRS
jumper is used to identify if the USC is
controlling GHBS/ BABR type breakers or
BABRS/GHQRS type breakers.
4-2 Switch Override Controller
The Switch Override Controller (SOC) is an
Application Specific Controller accepting
dry-contact closures as input. The SOC
can be installed in the 7X-Expansion
Chassis or in the bottom position of an
Expansion/Control Cabinet. The SOC will
accept only dry-contact closure devices
(i.e. switches, occupancy sensors,
Building Management System relay, etc.).
Contact closure is processed by the SOC
card, resulting in state control of the load
Relays / Breakers. Action of the devices
terminated for SOC card will not have any
effect on the system operation until the
system is correctly programmed. Program-
ming of the system must be performed by
qualified start-up personnel.
The personnel installing the panel with the
SOC card are responsible for providing and
terminating wires for low-voltage devices.
For low-voltage device termination for the
SOC card, please refer to SECTION 3.
