The control module also gives a separate event
code if a final trip has been performed, either by
the protection relay modules or the auto-reclose
function. Interruption of an auto-reclose cycle,
too, generates an event code.
In addition to the event codes the auto-reclose
function activates output data O1...O5 or O10
during an auto-reclose sequence.
Example19:
Setting of an auto-reclose sequence.
- Auto-reclosing is initiated by starting signals
of the protection relay modules.
- Signal AR1 inhibits cycle 1 and 2 when acti-
vated
- Signal AR2 initiates cycle 1 when activated.
Starting time 0.10 s
- Signal AR3 initiates cycle 1 and cycle 2 when
activated. The starting time for both cycles is
0.50 s
- Dead time of cycle 1 is 0.3 s
- Dead time of cycle 2 is 120 s
- Reclaim time 5 s.
As a default setting the auto-reclose functions
have been set out of operation (S78). Cycles 1
and 2 can be made operative just by giving
parameter S78 the value 1. Then both cycles are
initiated by the signals AR2 and AR3 and inhib-
ited by signal AR1. Cycles 3...5 are not initiated
by signals AR1...AR3.
Only parameters relating to auto-reclose cycles
1 and 2 are to be set. The default values for the
parameters of the other cycles may be kept
unchanged.

>99WS32:0:XX
; Cycle 2 not initiated if AR2 is activated
>99WS33:1:XX
; Initiate cycle 3 if AR3 is activated
>99WS35:0.50:XX
; Set AR3 starting time for cycle 2 at 0.5 s
>99WS36:120.00:XX
; Set cycle 2 dead time at 120 s

; Store set parameters
Note! It is not necessary to set parameter S34,
AR2 starting time for cycle 2, because the AR2
signal does not initiate cycle 2.
