13.3.3.3 Switch (SXCBR/SXSWI) M16675-3 v7tStartMove is the supervision time for the apparatus to start moving after a commandexecution. When the time has expired, the switch function is reset, and a cause-code is given.During thetIntermediate time the position indication is allowed to be in an intermediate (00)state. When the time has expired, the switch function is reset, and a cause-code is given. Theindication of the mid-position at SCSWI is suppressed during this time period when theposition changes from open to close or vice-versa if the parameterSuppressMidPos is set toOn in the SCSWI function.If the parameterAdaptivePulse is set toAdaptive the command output pulse resets when anew correct end position is reached. If the parameter is set toNot adaptive the commandoutput pulse remains active until the timertOpenPulsetClosePulse has elapsed.tOpenPulse is the output pulse length for an open command. IfAdaptivePulse is set toAdaptive, it is the maximum length of the output pulse for an open command. The defaultlength 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. IfAdaptivePulse is set toAdaptive, it is the maximum length of the output pulse for an open command. The defaultlength is set to 200 ms for a circuit breaker (SXCBR) and 500 ms for a disconnector (SXSWI).13.3.3.4 Bay Reserve (QCRSV) M16677-3 v3The timertCancelRes defines the supervision time for canceling the reservation, when thiscannot be done by requesting bay due to for example communication failure.When the parameterParamRequestx (x=1-8) is set toOnly own bay res. individually for eachapparatus (x) in the bay, only the own bay is reserved, that is, the output for reservationrequest of other bays (RES_BAYS) will not be activated at selection of apparatus x.13.3.3.5 Reservation input (RESIN) M16678-3 v3With theFutureUse parameter set toBay future use the function can handle bays not yetinstalled in the SA system.13.4 Interlocking IP15572-1 v2M13530-4 v3The main purpose of switchgear interlocking is:• To avoid the dangerous or damaging operation of switchgear• To enforce restrictions on the operation of the substation for other reasons for example,load configuration. Examples of the latter are to limit the number of parallel transformersto a maximum of two or to ensure that energizing is always from one side, for example,the high voltage side of a transformer.This section only deals with the first point, and only with restrictions caused by switchingdevices other than the one to be controlled. This means that switch interlock, because ofdevice alarms, is not included in this section.Disconnectors and earthing switches have a limited switching capacity. Disconnectors maytherefore only operate:Section 13 1MRK 511 358-UEN AControl266Application manual
