The motor has to cool down before operation can be resumed.
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
Test correct functioning of the motor protection as described hereafter. Perform the
functional test at the latest within the framework of 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.
Diagnostic M0022
TMS proof test M1950
Test procedure:
1. Set selector switch to position 0 (OFF).
2.
Return to the main menu and select the simulation value: Thermal test in
parameterTMS proof test M1950.
3.
Activate motor protection simulation: Press Ok push button.
The safety function is correct if no fault signal is displayed.
4.
Reset simulation: Press Ok push button or exit the simulation menu and reset
the selector switch to its initial position.
