Application and Setting Notes
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.

Trip-Circuit Supervision
Overview of Functions
The Trip-circuit supervision function recognizes disruptions in the trip circuit. When 2 binary inputs are used,
the function recognizes all disruptions in the trip circuit. If only 1 binary input is available, it will not recognize
disruptions at the circuit breaker.
The control voltage for the circuit breaker must be greater than the sum of the minimum voltage drops at the
binary inputs V
Ctrl
> 2 V
BImin
. At least 19 V are required for each binary input. This makes the supervision usable
only with a system-side control voltage of > 38 V.
Structure of the Function
The trip-circuit supervision is integrated into the Circuit-breaker function group. Depending on the number of
available binary inputs, it works with 1 or 2 binary inputs.
