Figure 3-2. Typical TCS Application

Alarm Outputs

Separate pairs of isolated contacts are provided for 5 alarm outputs. These outputs and the appropriate
terminals (indicated in parenthesis) are as follows:

Prog 1 (21-22), Prog (programmable). These alarm outputs may be programmed by the user to

Prog 2 (23-24)

operate for one or more conditions established during the setting up process.

RT (45-46)

RT (relay trouble). RT is a relay trouble alarm contact. It closes for failure of the power
supply, microprocessor, memory test, A/D converter test, and communications.

REC LO (47-48) REC LO (reclosing lockout). REC LO contact will close when the reclosing section of

the relay is in the lockout condition.

BF (49-50)

BF (breaker failure). BF contact provides an indication that a problem has been

detected with the controlled circuit breaker. The contact closes if: 1) a discontinuity is
detected in the trip circuit, 2) the 52a and 52b contacts do not agree on breaker
position, 3) the breaker did not close within the time set for the reclose fail timer, and
4) breaker operations count reaches the maximum breaker operations count limit.

Trip Circuit Sense

Terminals 34 (+) and 35 (-) are
connected internally to an
optically isolated sense circuit.
This feature is used by
connecting these terminals
across the trip output contacts
with terminal 34 connected to
the positive side. Lack of
continuity in the trip circuit
when the breaker is closed will
activate the BF alarm and
cause the reclosing logic to go
to a lockout condition. If this
function is NOT to be used,
then voltage equal to the
control input voltage must be
continuously connected to the
input terminals. a typical trip
c i r c u i t s e n s i n g ( T C S )
application is shown in Figure
3-2.

Control Power

Separate sets of terminals are provided for the main and optional redundant power supplies. This allows
them to be supplied from different power sources if desired. Power supply names are for reference only.
Either power supply (main or backup) may be connected to either set of terminals.

Communications

RS-485 connections are on terminals 2 through 4. These connections are for optional special applications
and are not activated on the standard product. The standard product communicates through the RS-232-C
