9.3 Supervision of the Secondary System
Operate delay
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 Operate delay begins. 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: Operate delay
•
Recommended setting value (_:6) Operate delay = 5.00 s
Set the Operate delay parameter so that overfunctions due to disturbing influences (such as switching
operations) are avoided. Siemens recommends using the default setting.
