Functioning

3.4.1 Manual operation

By turning the hexagon key actuator is operated manually (without a clutch).
By turning the hand crank actuator is operated manually (without a clutch). Motors is turned by manual operation.
Do manual operation only during standstill. If positioner is used the actuators tries to move back to the setpoint
position. Therefore only do manual operation while actuator is deenergized.

Mounting

4.1

Mounting position

The installation position is arbitrary, however not overhead.
4.2

Assembly with valve

Prior to mounting, the part-turn actuator must be checked for any damage. Damaged parts must be replaced by original
spare parts. After mounting, check part-turn actuator for damage to paint finish. If damage to paint-finish has occurred
after mounting, it has to be touched up to avoid corrosion.
For butterfly valves, the recommended mounting position is end position CLOSED (Prior to mounting, bring the part-
turn actuator to the mechanical end stop CLOSED by turning the handwheel clockwise.).
For ball valves, the recommended mounting position is end position OPEN (Prior to mounting, bring the part-turn
actuator to the mechanical end stop OPEN by turning the handwheel counterclockwise.).
Thoroughly degrease mounting faces of part-turn actuator and valve. .Apply a small quantity of grease to the valve
shaft. Place coupling sleeve onto valve shaft and secure (refer to figure Figure 4.2-1), ensure that dimensions X, Y, and
Z are observed (refer to Figure 4.2-2).
Apply non-acidic grease at splines of coupling. Fit actuator so that fixing holes in actuator and valve mounting flange
are in alignment. If necessary, move actuator up or down one tooth on the coupling. If required, turn handwheel/crank a
little in direction OPEN or CLOSE until holes align to the threads. Ensure that the spigot (if provided) mates uniformly in
the recess and that the mounting faces are in complete contact. Fasten the actuator with bolts of minimum quality 8.8
using lock washers. Fasten bolts evenly crosswise to the appropriate torque according to Figure 4.2-2.

Electric connection

Make sure that, appropriate power supplies are utilised assuring that during normal operation or in case of
plant or plant parts failure no dangerous voltages can reach the appliance.
If you do not observe this warning, death, severe body injuries or essential material damages can occur.
For short-circuit protection and for disconnecting the actuator from the mains, fuses and disconnect switches have to
be provided by the customer. The current values for respective sizing can be derived from the current consumption of
the motor (refer to nameplate).
The electrical connection must be carried out exclusively by suitably qualified personnel.
 Prior to connection, observe basic information contained in this chapter.
 After connection but prior to applying the voltage, observe the <Commissioning> chapter.
Carry out mains connection only with power supply switched off! Safeguard against unintentional switching on.
