OMICRON 143
Off-service diagnostic methods
Main contact Threshold value of the time interval between two consecutive bounces of
the main contact. For time intervals equal or below the threshold, the
contact is considered as closed.
Setting the value to 0.0 ms deactivates the contact bounce filter.
Auxiliary contact Threshold value of the time interval between two consecutive bounces of
the auxiliary contact. For time intervals equal or below the threshold, the
contact is considered as closed.
Setting the value to 0.0 ms deactivates the contact bounce filter.
Average coil current/voltage
Begin Start of the average coil current/voltage evaluation in percent of the time
period during which the current flows through the coil
End End of the average coil current/voltage evaluation in percent of the time
period during which the current flows through the coil
Begin of contact movement
2
Trip operation/
Close operation
Deviation of the contact travel from the rest position in percent of the total
travel
Begin of contact damping
3
Contact travel deviation Deviation of the actual contact travel from the distance the contact would
travel with its maximum velocity in percent of the total travel
Start evaluation at Start contact travel for the evaluation of the contact travel deviation
End evaluation at End contact travel for the evaluation of the contact travel deviation
Sequence
See Table 17-17: "Timing test sequences" on page 144.
1. The Close breaker before test check box is only active if the test sequence begins with the open command and no output is
set to Trigger IN.
2. Only available for O and C sequences and if the CB TN3 module is connected
3. Only available for O sequence and if the CB TN3 module is connected
