Definition in compliance with EN 15714-2/EN ISO 5211:
A part-turn actuator is an actuator which transmits a torque to the valve for less than
one full revolution. It need not be capable of withstanding thrust.

AUMA part-turn actuators SQEx 05.2
driven by an electric motor. For manual operation, a handwheel is provided. Switching
off in end positions may be either by limit or torque seating. Actuator controls are
required to operate or process the actuator signals.
For non-intrusive version (control unit: electromechanical version), limit and torque
setting is made via switches within the actuator.
For non-intrusive version (control unit: electronic version), limit and torque setting is
made via the actuator controls, neither actuator nor the actuator controls housing
have o be opened. For this purpose, the actuator is equipped with an MWG (magnetic
limit and torque transmitter), also capable of supplying analogue torque feedback
signals/torque indication and analogue position feedback signals/position indication
at the actuator controls output.
The actuator controls ACExC 01.2 may be mounted directly to the actuator or
separately on a wall bracket.
The actuator can be operated via the push buttons on the local controls of the actuator
controls or settings can be made in the actuator controls menu. The display shows
information on the actuator as well as the menu settings.
The functions of the actuator controls include standard valve control in OPEN-CLOSE
duty, positioning, process control, logging of operating data, diagnostic functions
right through control via various interfaces (e.g. fieldbus, Ethernet and HART).
App and software
Using the AUMA CDT software for Windows-based computers (notebooks or tablets)
and the AUMA Assistant App, actuator data can be uploaded and read, settings
can be modified and stored. The connection between computer and AUMA actuator
is established wireless via Bluetooth interface. With the AUMA Cloud, we provide
an interactive platform to collect and assess e.g. detailed device data of all actuators
within a plant.
