Priority
and time
tWaitForMaster
In single CB applications, one sets Priority = None. At sequential reclosing the function
of the first CB, e.g. near the busbar, is set Priority = High and for the second CB Priority =
Low. The maximum waiting time, tWaitForMaster of the second CB is set longer than the
“auto-reclosing open time” and a margin for synchronism check at the first CB. Typical
setting is tWaitForMaster=2secat the energizing side and perhaps 15 or 300 seconds at the
synchrocheck , synchronizing side.
AutoCont
and
tAutoContWait
, Automatic continuation to the next shot if the
CB is not closed within the set time
The normal setting is AutoCont = Disabled. The tAutoContWait is the length of time
SMBRREC (79) waits to see if the breaker is closed when AutoCont is set to Enabled.
Normally, the setting can be tAutoContWait = 2 sec.

10.3.2 Application
The apparatus control is a function for control and supervising of circuit breakers,
disconnectors, and grounding switches within a bay. Permission to operate is given after
evaluation of conditions from other functions such as interlocking, synchronism check,
operator place selection and external or internal blockings.
Figure
80 gives an overview from what places the apparatus control function receive
commands. Commands to an apparatus can be initiated from the Control Centre (CC), the
station HMI or the local HMI on the IED front.
