8.3 Supervision of the Secondary System
Delay failure indication
If it falls below the balance factor Threshold min/max and at the same time the maximum phase-to-phase
voltage exceeds the Release threshold, the delay of the failure indication begins, (parameter: Delay
failure indication). If both conditions persist during this time, the indication Failure is generated.
Blocking the Function
The following blockings reset the picked up function completely:
•
Externally or internally via the binary input signal
•
A protection pickup
The pickup signal of a protection function blocks the

Application and Setting Notes

Parameter: Threshold min/max
•
Recommended setting value (_:102) Threshold min/max = 0.75
The Threshold min/max parameter is used to set the ratio between the minimum (V
(V ) phase-to-phase voltage. Siemens recommends using the default setting.
max
Parameter: Release threshold
•
Recommended setting value (_:101) Release threshold = 50 V
With the Release threshold parameter you set the lower limit of the maximum phase-to-phase voltage
(V ). Siemens recommends using the default setting.
max
Parameter: Delay failure indication
•
Recommended setting value (_:6) Delay failure indication = 5.00 s
Set the Delay failure indication parameter so that overfunctions due to disturbing influences (such as
switching operations) are avoided. Siemens recommends using the default setting.
