9272000990 Rev J BE1-BPR Functional Description 4-23
TD79 Command Example:
Set reclose shot 1 at 3 cycles to allow for arc de-ionization. Set reclose shot 2 at 2.5 seconds and disable
reclose shot 3. Set the reset time at 30 seconds, the fail time at 2 minutes, and the maximum reclose time
at 2.5 minutes.
TD791=3C; TD792=2.5S; TD793=0; TD79R=30S; TD79F=120S; TD79M=150S
There are four inputs to a reclose function, three outputs, and one mode programmable feature (TYPE).
The inputs and outputs are shown in Figure 4-7.
Recloser Inputs. Each input is fully programmable using the logic recloser command (LR) which allows
each input to be defined as a BESTlogic logic term. The function of each input is:
START:
Starts the reclose sequence if the RESET input is not true.
RESET: Begins reset timing and opens the CLOSE output. If RESET remains true for the reset
time delay (TD79R), the recloser goes to the reset state and the recloser shot counter is
reset.
WAIT: Stops the reclose sequence at any point. The reclose sequence is inhibited as long as
the wait input is present. When the wait input is removed, the sequence continues from
the point that it was stopped.
DTL: Drives the reclose function immediately to the lockout state. Lockout has precedence
over all other inputs. When lockout is removed and the breaker is closed, the recloser
begins reset timing. When lockout is removed and the breaker is open, the recloser
remains in the lockout state.

Parameter Parameter Selections Defaults
type 0 (disabled)
1 (standard recloser)
2 (power-up reclose)
The recloser is enabled only when
the type selection is 1 or 2 and the
start and reset logic is programmed.
start any logic variable
reset any logic variable
wait any logic variable
lockout any logic variable
LR Command
Purpose:
Reads or programs the recloser input logic.
Syntax: LR[=,,,,]
Comments: Access area 1 password is required to change setting.
Example 1:
Define a recloser that is initiated by any true signal to the breaker and reset when the 52a
contact closes. Given: Previous BESTlogic definitions have defined a logic scheme that
has all BFI TRIP signals driving O5 for a retrip function, and have defined I1 to be a 52a
input, I6 to be a wait input, and I7 to be a drive to lockout input.
LR=1,O5,I1,I6,I7
Example 2:
Define the same logic except that a 52b input is connected to I1 instead of the 52a and
there is o wait input.
LR=1,O5,/I1,0,I7
