one wants to get the UNSUCCL (Unsuccessful closing) signal in the case the CB does not
respond to the closing command, CLOSECMD, one can set UnsucClByCBChk = CB
check and set tUnsucCl for instance to 1.0 s.
Priority
and time
tWaitForMaster
In single CB applications, one sets Priority = None. At sequential reclosing the function
of the first CB, for example 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 =2s.
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
STBRREC (79) waits to see if the breaker is closed when AutoCont is set to Enabled.
Normally the setting can be tAutoContWait=2 s.

11.4.2 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.
The complete apparatus control function is not included in this product,
and the information below is included for understanding of the principle
for the use of QCBAY, LOCREM, and LOCREMCTRL for the selection
of the operator place.
