BE1-79A Functional Description

9310200990 Rev G

Output Terminals

Description

17, 20

This Anti-Pump output closes for the duration of reclose timing (time delay
reclosing) except when output C5 closes. If C5 closes, output C6 will only
close when voltage is sensed at contact sensing input V4. (BC

∗

Z1) Note: At

reset, operational state of C6 (closed or open) is determined by the first time
delay reclose setting. If first reclose time delay setting is “0”, C6 is open in the
reset position. If first reclose time delay setting is greater than “0”, C6 is open
in the reset position.

15, 20

Anti-pump output. Closes for the duration of reclose timing except if output C6
closes. If C6 closes, output C7 will close only if voltage is sensed at contact
sensing input V2. ((BC+Z1)

RS output. Can be configured as a normally open (NO) or normally closed
(NC) contact. Can be set to energize for an adjustable duration after the start
of a reclose cycle. The interval between the start of the reclose sequence and
C8 energizing is also adjustable. A detailed explanation of programming the
RS output is provided in Section 4,

Description

12, 17

Closes momentarily when voltage is sensed at input V4 and the relay is in a
reset condition. (Z2

∗

E6)

13, 14

Closed during reset and open when voltage at input V3 is sensed. During a
reclose sequence, C2 remains open until the relay returns to reset. (E1)

15, 16

Functions as a programmable alarm contact. Can be set to function as a relay
fail output or a combination relay fail/lockout output. a detailed explanation is
provided in Section 4,

18, 19

Closed any time that the unit is not in reset. (E5)

17, 19

Closes for three seconds after a reclose timer expires. (AB)

14, 17

Anti-pump output. Closes for the duration of reclose timing except if output C5
closes. If C5 closes, output C6 will close only if voltage is sensed at contact
sensing input V4. (BC

RS output. Can be configured as a normally open (NO) or normally closed
(NC) contact. Can be set to energize for an adjustable duration after the start
of a reclose cycle. The interval between the start of a reclose sequence and
C8 energizing is also adjustable. A detailed explanation of programming the

5, 8

Closes when the relay is in reset and voltage is sensed at input V3. C9
remains closed until the relay reaches either a lockout or reset condition.
(GH+E3)

C10

1, 2

Closed only during a reset condition. Opens and stays open when a reclose
timing begins or is running. (E4)
