During the tIntermediate time the position indication is allowed to be in an
intermediate (00) state. When the time has expired, the switch function is reset. The
indication of the mid-position at SCSWI is suppressed during this time period when the
position changes from open to close or vice-versa.
If the parameter AdaptivePulse is set to Adaptive the command output pulse resets
when a new correct end position is reached. If the parameter is set to Not adaptive the
command output pulse remains active until the timer tOpenPulsetClosePulse has elapsed.
tOpenPulse is the output pulse length for an open command. The default length is set
to 200 ms for a circuit breaker (SXCBR) and 500 ms for a disconnector (SXSWI).
tClosePulse is the output pulse length for a close command. The default length is set to
200 ms for a circuit breaker (SXCBR) and 500 ms for a disconnector (SXSWI).
SuppressMidPos when Enabled will suppress the mid-position during the time
tIntermediate.
Bay Reserve (QCRSV)
The timer tCancelRes defines the supervision time for canceling the reservation, when
this cannot be done by requesting bay due to for example communication failure.
When the parameter ParamRequestx (x=1-8) is set to Only own bay res. individually
for each apparatus (x) in the bay, only the own bay is reserved, that is, the output for
reservation request of other bays (RES_BAYS) will not be activated at selection of
apparatus x.
Reservation input (RESIN)
With the FutureUse parameter set to Bay future use the function can handle bays not
yet installed in the SA system.
