2.2. Short description
Part-turn actuator Definition in compliance with 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 are driven by an electric motor. For control in motor
operation and for processing the actuator signals, controls are integrated within the
housing.The actuator can be operated easily on site via the local controls.A
handwheel or crank is provided for manual operation.Manual operation is possible
without change-over.
The swing angle is limited by internal end stops. Switching off in end positions may
be either by limit or torque seating.
AUMA CDT The AUMA CDT software (accessories) can be used to establish a connection to a
computer (PC, laptop or PDA). Among others, the software can be used to read in
and out data and to save and modify settings.
The connection between computer and the integral actuator controls is made using
a service cable.

4. Assembly
4.1. Mounting position
The product described in this document can be operated without restriction in any
mounting position.
4.2. Actuator: mount to valve
4.2.1. Actuator for assembly: prepare
Prior to mounting, both valve and actuator must be in the same end position!
●For butterfly valves, the recommended mounting position is end position
CLOSED.
●For ball valves, the recommended mounting position is end position OPEN.
In compliance with the order, the actuator is supplied either in position CLOSED or
position OPEN.The mechanical position indicator supplies information on the set
position.
If the actuator position was not modified and agrees with the valve position, the
actuator can be mounted in the supplied position.
In case the actuator is in an incorrect position:
1. Operate the actuator into the same position as the valve via push buttons OPEN,
STOP, CLOSE while in motor operation.For motor operation, please refer to
<Actuator operation at the local controls> chapter.
2. Should the electrical connection not be available at the time of assembly, the
actuator can be operated into the required end position using the handwheel.
2.1 Turn the handwheel or the crank handle until reaching the internal end
stop of part-turn actuator (same end position OPEN or CLOSED as valve).
2.2 Turn handwheel by approximately two turns (overrun) in the opposite dir-
ection.
After this procedure, the actuator can be mounted to the valve.
4.2.2. Output drive for coupling
Application ●For valves with connections according to EN ISO 5211
●For rotating, non-rising valve stem
Assembly ●The actuator is mounted to the valve using a coupling placed onto the valve
shaft.
●Unbored couplings must be adapted and machined to match the valve shaft
prior to mounting (e.g. with bore and keyway, two-flat or square bore)
