If the >Start signal is active and no release signal is present after elapse of the settable supervision time for
the starting signal, the pickup is blocked and an indication to this effect is output. The Health signal changes
to the state Warning. The blocking is reset with the dropout of the starting signal.
The binary input signals only take effect if the binary inputs are activated for at least 10 ms (SW filter, see
Figure 7-7).
