Siemens 6MD85, Manual

Page: 226 / 1256

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, this can be ensured 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
(_:101) Action time
=
300 ms
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 internal indication
CB
open-circuited
for the set time. If the input signal
>Input
becomes active after external delayed manual
closure, the indication
(_:300) Detected
is output as long as the dropout delay is active.
