BE1-79A General Information 1-1
SECTION 1 • GENERAL INFORMATION
DESCRIPTION
The BE1-79A Multiple Shot Reclosing Relay is an economical, microprocessor based relay that automatically
recloses circuit breakers which have been tripped by protective relays or other devices in power transmission
and distribution systems. The BE1-79A offers true “plug and play” convenience; itcan be installed in an existing
GEtypeS2casewithnowiringchangesrequired. GeneralElectrictypeACR11A,ACR11B,ACR11C,ACR11E,
and ACR11F reclosing relays can be directly replaced by the BE1-79A. The BE1-79A is also available in a
Basler S1 case for new installations.
FEATURES
BE1-79A Multiple Shot Reclosing Relays have the following standard features:
• Rugged construction in a draw-out steel case
• A maximum of four automatic reclosures
• A maximum of four automatic resets
• Lockout function
• Selectable instantaneous or delayed first reclosure
• Selectable internal or external instantaneous jumper
• Selectable normally closed or normally open RS output contact
• Selectable Relay Fail or Lockout
and Relay Fail output contact
•Selectable contact sensing voltage range
Controls And Indicators
The front panel has indicators to verify relay power and recloser status. A Reset switch is provided to restore
the unit to the reset mode by clearing a reclosing sequence or a lockout condition. The left side of the relay
cradle has switches to configure the relay for either ACR11A or ACR11B operation. The right side of the cradle
has a switch(S4) to select either an internal or external jumper for an instantaneous first relcose. The left side
of the cradle has a switch(S5) to select either normally open or normally closed operation of the RS contact.
Communications
All relay settings are read or changed through the Serial Port located on the front panel. The BE1-79A uses
ASCII protocol.
Power HoldUp Circuit
The BE1-79A is available with an internal power holdup circuit. This circuitry enables the output contacts to be
maintained for a minimum of 40 cycles after nominal operating power is removed from relay terminals 5 and 6.
PRIMARY APPLICATION
The BE1-79A Multiple Shot Reclosing Relay automatically recloses circuit breakers which have been tripped
by protective relays or other devices in power transmission and distribution systems.
Over 90% of faults occurring on overhead lines may be cleared by momentarily de-energizing the line. Once
the circuit breaker has been opened to de-energize the line, the BE1-79A provides a reliable automatic
reclosure. The advantages are:
•Improved Service Continuity - returns the lineto service quickly, preserving line integrity and minimizing
outage effects on critical loads.
•System Stability - prevents disjointing of the system grid.
•Higher Line Availability - decreases likelihood of permanent loss of line
.

SECTION 3 • FUNCTIONAL DESCRIPTION
GENERAL
BE1-79A Multiple Shot Reclosing Relays are microprocessor based devices that provide automatic reclosing
of circuit breakers. This section describes the hardware, circuit operation, and software functional descriptions.
HARDWARE
The BE1-79A relay is available in an S1 cradle and case(200 series) or an S2 cradle without a case(100 series).
200 series Description
This BE1-79A consists of a fabricated steel and phenolic enclosure with a draw-out cradle assembly. The case
has the same overall dimensions as a Basler Electric or General Electric S1 case.
100 series Description
This BE1-79A consists of a draw-out cradle assembly which is intended for installation in an existing S2 case.
A case is not provided with the cradle assembly.
CIRCUIT OPERATION
Circuit operation is divided into
Inputs
,
Microprocessor
, and
Outputs
. Relay circuit functions are illustrated in
Figure 3-1 and described in the following paragraphs.
Figure 3-1. Functional Block Diagram

3-2 BE1-79A Functional Description
Inputs
There are four types of inputs to the BE1-79A relay. They are:
• Operating AC/DC Power
• Contact Sensing Inputs
• Reset Switch
• Serial Communication Port
Operating AC/DC Power.
Operating power for the internal circuitry is applied to the isolated internal switching
power supply. The power supply operates over a range of 120 to 240 Vac or 125 to 250 Vdc with no changes
in connections or jumpers required. The operating power input is not polarity sensitive and is not disrupted by
variations in the supply voltage or frequency over the power supply operating range. The power supply
generates 24 Vdc.
Part number 9 3102 00 101 relays are equipped with hold-up circuitry which maintains relay function for a
minimum of 40 cycles after nominal operating power is removed.
Contact Sensing Inputs.
The contact sensing inputs are designated V1, V2, V3, V4, and V5. Each input uses
an opto-isolator to provide isolation from external power sources. Each contact sensing input is rated for 48 Vdc
to 250 Vdc and 120 Vac to 240 Vac at 45 to 65 hertz.
Inputs V1 through V4 can operate at any one of three jumper-
selectable voltage ranges. Table 3-1 lists the nominal operating
voltage for each of the three jumper positions. Each input has a
dedicated jumper that is located on the digital circuit board.
JumperP3 controlsthe operatingvoltage forV1, P4controls V2,
P5 controls V3 and P6 controls V4. Instructions for placing each
jumper in the desired position are provided in Section 5,
Installation
. Input V5 is dedicated to monitoring the relay power
supply input and is not jumper selectable.
Note
In certain applications where 240 Vac control voltage is used, control circuit feedback
can occur through system inductive coupling. This feedback can result in erroneous
signals, causing relay operation. If there is a potential for control circuit feedback, the
jumper-selectable voltage range should be changed from the 48 Vdc factory default
setting to a higher position. Selections are provided in Table 3-1.
The function of each input depends on the operating configuration of the relay. Tables 3-2 and 3-3 describe the
function of each contact sensing input for each relay configuration. The G.E. nomenclature used for each input
is provided in parenthesis following each description.
Table 3-2. Contact Sensing Inputs Description For ACR11A Operation
Input Terminals Description
V1 3, 4 This input is typically connected to a 52A contact which results in voltage being
sensed when the breaker is closed. If V1 senses voltage within three seconds
after the Reset 1, 2, 3, or 4 timer expires, a reset will be initiated. If the relay is in
Lockout, a reset will be initiated anytime V1 senses voltage.

BE1-79A Functional Description 3-3
V2 7, 8 This input is connected to a 52B contact which results in voltage being sensed
when the breaker is open. This input is typically used to provide an anti-pump
feature. If voltage is removed from V2 during a reclose attempt, the anti-pump
feature will prevent a further reclose attempt until the next reclose set time is
reached. This prevents multiple reclose attempts for a single reclose setting. (Z)
V3 11, 12 This input is used to monitor the 52B contact while the relay is in a reset condition.
When V3 senses voltage, the relay initiates a reclose sequence. (E Operate)
V4 --- This input is not used in this application.
V5 5, 6 This input is internally connected to the relay power supply terminal. A loss of
sensing voltage at this input will cause the relay to store all necessary data in
memory.
Table 3-3. Contact Sensing Inputs Description For ACR11B Operation
Input Terminals Description
V1 3, 4 This input is typically connected to a 52A contact which results in voltage being
sensed when the breaker is closed. If V1 senses voltage within three seconds
after the Reset 1, 2, 3, or 4 timer expires, a reset will be initiated. If the relay is in
Lockout, a reset will be initiated anytime V1 senses voltage.
(E Reset)
V2 6, 7 Voltage sensed at this input causes the relay to start a reclose sequence. (Motor)
V3 11, 12 This input is used to monitor the 52B contact while the relay is in a reset condition.
When V3 senses voltage, the relay initiates a reclose sequence.
(E Operate)
V4 11, 17 This input is connected to a 52B contact which results in voltage being sensed
when the breaker is open. This input is typically used to provide an anti-pump
feature. If voltage is removed from V4 during a reclose attempt, the anti-pump
feature will prevent a further reclose attempt until the next reclose set time is
reached. This prevents multiple reclose attempts for a single reclose setting. (Z)
V5 5, 6 This input is internally connected to the relay power supply terminal. A loss of
sensing voltage at this input will cause the relay to store all necessary data in
memory.
Reset Switch.
This momentary switch clears the In Sequence or Lockout LEDs located on the front panel and
restorestherelayto aresetcondition. Theresetswitchperforms thesamefunctionasthemanual clutchrelease
on the General Electric ACR11 relays. Operating power must be applied to terminals 5 and 6 for a reset to
occur.
Serial Communication Port.
The serial communication port is a standard RS-232 (DB-9) female connector
located on the front panel. This serial port provides the means to configure and read relay settings.
Microprocessor
All reclosing and communication functions are coordinated by the microprocessor. The BE1-79A uses an eight
bit microprocessor with integral ROM (read only memory) and RAM (random access memory). The
microprocessor is monitored by awatch-dog circuit which will reset the microprocessor if a problem is detected.
Outputs

3-4 BE1-79A Functional Description
The BE1-79A has ten outputs. The function of each output depends on the operating configuration of the relay.
