Every closure of the circuit breaker is recorded in the process. Therefore, detection is suppressed automatically
in the event of a close command by the internal AREC function of the device.
If external close commands are possible (actuation of the circuit breaker by other devices), which are not
intended to prompt detection of a manual closure (for example, with an external reclosing device), this can be
assured in 2 ways:
•
The input signal is connected in such a way that it is not activated in the event of external close
commands.
•
The external close command is connected to the blocking input >Block manual close for manual
closure detection.
Parameter: Action time
•
Recommended setting value (_:6541:101) Action time = 0.30 s
In order to ensure independence from manual activation of the input signal, the detection function is
extended for a defined length of time using the parameter Action time.
Siemens recommends an action time of 300 ms.
Parameter: CB open dropout delay
•
Default setting (_:102) CB open dropout delay = 0 ms
With the CB open dropout delay parameter, you can maintain the effectiveness of the internal indication
CB open for the set time. If the input signal >Input becomes active with a delay after an external close
command, the indication
