12.3.2.
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.
If the inside temperature limits are exceeded or fallen short of, the temperature
monitoring of electronics trips.
The actuator is switched off and the following fault signals are issued:
●
LED 3 (motor protection tripped) on the local controls is illuminated.
●
Status indications
S0007
or
S0011 Failure
display a fault.
The fault
Details
is displayed when selecting
Thermal fault
.
After thermal motor tripping, a thermal fault signal is issued. The reason for the fault
must be checked and remedied. Once the reason for the fault is remedied, the fault
must be acknowledged (RESET).
Information
For active operation commands, the command is directly executed following acknow-
ledgement.
Manual acknowledgement can be made:
●
By toggling the selector switch in direction ESC when selector switch is set to
LOCAL.
