Warning signalling via yellow indication light
Signification (default) Signal Indication
For reasons of accuracy, we recommend selection
of the stroke higher than 60 % of the maximum turn
range.
→ Abort warning: Set again Low limit Uspan para-
meter via AUMA CDT software within the Position
transmitter potentiometer sub-menu.
→ Remedy warning: Reduce maximum turn range
by replacing the reduction gearing through the
AUMA service.

12.2. Fuses
12.2.1. 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.
Hazardous voltage!
Risk of electric shock.

Disconnect device from the mains before opening.

12.2.2. 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.
