4. Assembly
4.1. Mounting position
AUMA actuators can be operated without restriction in any mounting position.
4.2. Ball handle to handwheel: fit
To avoid damage during transport, the ball handle is fitted at the rear of the
handwheel.
Prior to commissioning, mount the ball handle into correct position:
1. Remove cap nut [1] and pull out ball handle [2].
2. Insert ball handle [2] in correct position and fasten with cap nut [1].
Information The end position detection can be modified by turning the handwheel while actuator
is not mounted to a valve. Therefore, we recommend not to turn the handwheel prior
to mounting to the actuator to the valve.
4.3. Actuator: mount to valve
4.3.1. 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 the respective symbol
(OPEN/CLOSED) of mechanical position indication corresponds to the
mark (same end position OPEN or CLOSED as valve).
Information: Since the actuator is not equipped with internal end stops
(mechanical limits), the symbol should not be turned ahead of the mark.
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.
