Depending on the parameter setting (motor protection behaviour), the fault signal is
either automatically reset or the fault signal has to be acknowledged.
The acknowledgement is made:
●
in selector switch position Local control (LOCAL) via push button RESET.
●
In selector switch position Remote control (REMOTE) with Reset command
via fieldbus.
Proof-test motor protection
The functionality of the motor protection must be verified at the latest when performing
the maintenance (refer to chapter <Servicing and maintenance>).
The test is performed by simulating the motor protection signal via actuator controls
local controls:
Required user level:
Specialist (4)
or higher.
