Attention
By default, every AS-i master sends "1111" for the parameter bits. This
means that the motor is automatically in secure monitoring mode:
thermoclick, trip, no auto reset.
If you want to use these settings, you do not need to assign any para-
meters.
Attention
If you set the "Behavior in the event of overload - temperature sensor" para-
meter to "Warn", the motor starter automatically sets the "Auto reset" para-
meter to "YES". As a result, the "General warning" signal is
automatically cleared after the cause of the fault is eliminated.
Self-test function with trip reset
Attention
If trip reset (output DO-0.3) is applied for longer than 2 seconds and there is
no general fault / general warning present, the self-test function is triggered.
This results in overload tripping with "Warn/Trip", depending on the
"Behavior in the event of overload - temperature sensor" parameter (PO-0.2)
