Definition in compliance with EN 15714-2/EN ISO 5210:
A multi-turn actuator is an actuator which transmits torque to a valve for at least one
full revolution.

driven by an electric motor. A handwheel is available for setting and emergency
operation.
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.
In combination with output drive type A, the actuator is capable of withstanding thrust.
Please note: Actuators in multiport valve product variant are multi-turn and can
approach different valve connection. Consequently, no end stops are available. The
designations "End position OPEN" and "End position CLOSED" used in the following
chapters signify the MPV positions, or "Position reached" for this product variant.
Direction OPEN corresponds to an operation in CW direction and direction CLOSE
to an operation in CCW direction.
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).
