There is a time difference t
opening of the POSCLOSE auxiliary contact. Similarly, there is a time gap t
between the time when the POSOPEN auxiliary contact opens and the main contact
is completely open. Therefore, in order to incorporate the time t
factor needs to be added with 10 to get the actual opening time. This factor is
added with the OpenTimeCorr (=t
the value set with the CloseTimeCorr (t
The last measured opening travel time tTravelOpen and the closing travel time
tTravelClose are available through the Monitored data view on the LHMI or
through tools via communications.
Alarm limit check
When the measured open travel time is longer than the value set with the tOpenAlm
setting, the TRVTOAL output is activated. Respectively, when the measured close
travel time is longer than the value set with the tCloseAlm setting, the , the
TRVTCAL output is activated.
It is also possible to block the TRVTCAL and TRVTOAL alarm signals by activating
the BLOCK input.

Operation counter

The operation counter subfunction calculates the number of breaker operation
cycles. Both open and close operations are included in one operation cycle. The
operation counter value is updated after each open operation.
The operation of the subfunction can be described by using a module diagram. All
the modules in the diagram are explained in the next sections.
