Automatic reset fuse as short-circuit protection for external 24 V DC supply for
customer (see wiring diagram)
Information After fuse replacement, replace and fasten cover.
10.3.2 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.The thermoswitch is tripped as soon as the max. permissible winding
temperature has been reached.
The actuator is switched off and the following signals are given:
●
LED 3 (thermal fault) on the local controls is illuminated.
●
Status indication S0: Operation mode OFF/LOCAL = FLT + NR
●
Status indication S0/S6: Operation mode REMOTE = FAULT IND.
●
Status indication S1: THERMAL FAULT
The motor has to cool down before the operation can be resumed. Depending on
the parameter setting, the fault signal is either automatically reset or the fault signal
has to be acknowledged.
