11.3.2. Motor protection (thermal monitoring)
In order to protect against overheating and impermissibly high surface temperatures
at the actuator, PTC thermistors or thermoswitches are embedded in the motor
winding. Motor protection trips as soon as the max. permissible winding temperature
has been reached.
The actuator is switched off and the following signals are given:
●
LED 3 (motor protection trippped) on the local controls is illuminated.
●
The status indication S0007 or S0011 Failuredisplays a fault..
The fault Details is displayed when selecting Thermal fault.
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.
