13.2.1. Fuses within the actuator controls
The primary fuse F1 is located on the power board (device protection fuse). It
becomes visible when removing the cover to the controls. The fuse cannot be
replaced. Only by replacing the entire power board can the fuse be exchanged.
Electric shock due to presence of hazardous voltage!
Failure to observe this warning results in death or serious injury.

13.2.2. Motor protection (thermal monitoring)
In order to protect against overheating and impermissible high surface temperatures
at the actuator, a PTC thermistor is embedded in the motor winding. Motor protection
trips as soon as the max. permissible winding temperature has been reached.
The actuator is stopped and controls signals a fault. The left indication light of the
local controls is blinking in red.
The motor has to cool down before operation can be resumed. Depending on the
parameter setting, the fault signal is either automatically reset or the fault signal has
to be acknowledged.
The acknowledgement is made:
●
via push button [2] in operation mode LOCAL (press and hold down push button
more than 1 second)
●
or with the reset command via fieldbus.
