Applications
The Control Indicator Module (CIM) is designed as a universal substation automation
solution by combining multiple control and monitoring functions into a single space-saving,
cost-effective unit.
The CIM allows automation while maintaining a manual fail-safe switch. It is designed to
monitor and control up to three breaker trip coils (single, dual, or triple coils). By incorporating
a CIM into a new or existing system, functions of several individual devices (including two
local/remote switches, reclosing and SCADA control, and status monitoring devices) can be
combined into one smaller, more compact, cost-effective device.
The CIM provides visual status indication through LEDs located on the front panel, as well as
backup, failsafe manual switch control.

CIM OPERATIONAL DESCRIPTION
The CIM is a Breaker Control Switch with expanded functionality that provides r
emote/local
breaker control (trip/close), remote/local Recloser control, and Breaker Trip Coil monitoring.
The unit contains a serial or parallel SCADA interface for remote control and monitoring functions.
The CIM will control and monitor three different types of circuit breaker arrangements: a single
trip coil, a dual trip coil, and a circuit switcher or ganged single pole breakers with single trip
coils. All controls, indicators, and electronics are contained in a compact modular enclosure
that can be horizontally or vertically panel mounted.
Control Functions: The CIM can trip and close a circuit breaker three different ways:
1. from a manual Breaker Contr
ol Switch mounted on the front panel
2. from a signal from any local Protective Relay device
3. from SCADA
The CIM unit can also control a local automatic Reclose Relay (79) operation three different
ways:
1. manual enable or disable switch
2. remote enable or disable from SCADA
3. manual trip disables Reclose
SCADA Functions: The CIM units contains either a RS-485 interface with DNP 3.0 or
Modbus communications protocol or a simple 8 bit parallel inter
face. The interface is con-
trolled by the SCADA enable/disable switch on the front panel of the CIM.
Serial Interface
Via the Serial Link the user can:
• T
rip one or two isolated circuit breakers
• Close the circuit breaker
• Enable and Disable Reclose
• Monitor one, two or three trip coils for integrity
• Read the status of the CIM and circuit breaker
• Recall recent events and the time at which they occurred
Eight Bit Parallel Interface
There are three contr
ol signals, a single trip signal and two close signals.
The Trip Signal:
• “TR” signals the circuit breaker to immediately trip.
The Close Signals:
• “NC” signals the circuit breaker for a Normal Close with Reclose enabled
for the next trip cycle.
• “TC” signals the circuit breaker for a Test Close. The breaker would immediately close.
However Reclose would be blocked for the next trip cycle. (A “NC” signal would be
required to reenable Reclose after a “TC” or Test Close.)
There are five monitor functions:
• “XA” monitors the “A” contact on the circuit breaker
• “XB” monitors the “B” contact on the circuit breaker
• “XRC” monitors the status of the Reclose function
• “XTM” monitors the status of the trip coil
• “XSCADA” monitors the status of SCADA (Enabled/Disabled)
