Table 2-1. BE1-79M Controls and Indicators (Refer to Figure 2-1)
Locator Control or Indicator Function
A RECLOSE TIME
Controls (1, 2, 3)
Establish reclose time delays for corresponding time-
delayed reclosure attempts. Individually thumbwheel
adjustable from 00.1 to 99.9 seconds in 00.1 second
increments or if reclose time delay option is A7, second and
third RECLOSE TIME thumbwheels are adjustable from
001 to 999 seconds in one second increments. A setting of
000 on a RECLOSE TIME thumbwheel indicates the
reclosing attempt is not desired and sends the relay to
lockout at this point in the reclosing sequence.
B RESET Control Establishes automatic reset interval. Thumbwheel
adjustable from 10 to 1000 seconds in 10 second
increments. Optionally adjustable from 1 to 100 seconds in
1 second increments. A setting of 00 indicates a reset time
of 1000 seconds or optionally, 100 seconds.
C RESET Switch Momentary toggle switch, which extinguishes STATUS
LEDs (except LOCKOUT). Accessible by linkage, which
extends through bottom of front cover.
D RESET LED ON when relay is in RESET.
E PILOT or RESET INHIBIT
LED (Optional)
With PILOT option, LED is ON when pilot output relay coil
is energized. Remains ON until activation of manual
RESET lever, power loss, or when relay reaches RESET if
STATUS LED reset is optionally selected by logic switch
S23. With RESET INHIBIT option, LED is ON when reset
inhibit input is closed.
F POWER LED ON when the power supply is delivering a nominal ±12 Vdc
to internal circuitry.
G OUTPUT ENERGIZE LED ON when reclose output relay coil is energized.
H RELAY FAIL LED ON when relay is not operable. Also ON during power-up
sequence.
I STATUS LEDs
( INST., 1, 2, 3)
(LOCKOUT)
Latched ON to indicate progression of reclosing sequence.
Extinguished by RESET lever, power loss, or when relay
reaches RESET if STATUS LED reset is optionally
selected by logic switch S23.
ON when relay is in LOCKOUT. (Non-latching.)
J INSTANTANEOUS TRIP
(Optional)
Five toggle switches, which enable or block instantaneous
tripping of circuit breaker. Numbers correspond to the relay
state or a specific trip depending on the type of reclosing
sequence in progress.
K RECLOSE FAIL LED
(Optional)
ON when circuit breaker 52b contact does not open within
selected time after reclose output has been energized.
L RECLOSE FAIL Control
(Optional)
Limits duration of reclose command signal. Thumbwheel
adjustable from 0.1 to 9.9 seconds in 0.1 second
increments. For a setting of 00, the reclose command
signal is continuous until the breaker closes.
M MAX. CYCLE LED
(Optional)
ON when maximum cycle limit, as established by the MAX.
CYCLE control, has been exceeded.
