If SYNC as an internal function or external device is not operated by the
injection, it may be connected as a permanent high signal or controlled by a
switch.
3.
Read and make notes of the reclosing operation counters.
Local HMI tree:
Main menu/Tests/Function status/Control/SMBRREC(79,0->1)/
1:SMBRREC
Possibly reset the counters to zero. Counters are reset in the RESET menu.
4.
Make arrangements for the simulation of the CB, for example as in figure 14.
5.
Make arrangements for indication, recording and time measurements.
The signals for CBPOS, START, CLOSECB, READY and other relevant
signals should preferably be arranged for event recording with time tagging.
If that is not possible, other means of time measurement and recording should
be arranged.

Switching the auto-reclosing function On and Off

Procedure:
1.
Set the Operation setting to Off and check the state.
2.
Set the Operation setting to On and check the state, including SETON and
READY.
The CB should be closed and ready.
3.
If external control Off/On is connected, check that it works.
Set Operation to ExternalCtrl, and use that control to switch On and Off, and
check the state of the function

Verifying the auto-reclosing function

Select the test cases to be run according to what is applicable to the particular
application. It can be, for example, three-phase single-shot reclosing or two-shot
reclosing. Below a case with three-phase single-shot reclosing is described.
Procedure:
1.
Set Operation = On.
2.
If SYNC is not to be operated ensure that the SYNC input is activated. If the
SYNC function is to be included, ensure that it is supplied with the
appropriate AC quantities.
3.
Simulate CB closed position by closing switch SC to make the BR relay pick-
up.
4.
Simulate CBREADY by closing the switch SRY, and leave it closed.
5.
Inject AC quantities to give a trip to the BR and to the START input.
Observe and preferably record the operation. The BR relay shall trip and
reclose (pick-up). After reclosing, the SRY switch can be opened for about 5
s and then closed again.
