Safety notes

• This device has been designed for use in stationary heating, ventilation and air

conditioning systems and must not be used outside the specified field of application,

especially in aircraft or in any other airborne means of transport.

• Outdoor application: only possible in case that no (sea)water, snow, ice, insolation

or aggressive gases interfere directly with the actuator and that is ensured that the

ambient conditions remain at any time within the thresholds according to the data

sheet.

• Only authorised specialists may carry out installation. All applicable legal or

institutional installation regulations must be complied during installation.

• The switch for changing the direction of motion and so the closing point may be

adjusted only by authorised specialists. The direction of motion is critical, particularly

in connection with frost protection circuits.

• The device may only be opened at the manufacturer’s site. It does not contain any

parts that can be replaced or repaired by the user.

• Cables must not be removed from the device.

• The device contains electrical and electronic components and must not be disposed

of as household refuse. All locally valid regulations and requirements must be

observed.

Product features

Mode of operation The actuator moves the valve to the desired operating position at the same time as

the integrated capacitors are loaded. Interrupting the supply voltage causes the valve

to be moved to the selected emergency setting position (POP) by means of stored

electrical energy.

Pre-charging time (start up) The capacitor actuators require a pre-charging time. This time is used for charging the

capacitors up to a usable voltage level. This ensures that, in the event of an electricity

interruption, the actuator can move at any time from its current position into the preset

emergency setting position (POP). The duration of the pre-charging time depends

mainly on how long the power was interrupted.

[s] = Pre-charging time in seconds

Delivery condition (capacitors) The actuator is completely discharged after delivery from the factory, which is why the

actuator requires approximately 20 s pre-charging time before initial commissioning in

order to bring the capacitors up to the required voltage level.

Simple direct mounting Simple direct mounting on the globe valve by means of form-fit hollow clamping jaws.

The actuator can be rotated by 360° on the valve neck.

Manual override Manual control with push-button possible - temporary. The gear is disengaged and the

actuator decoupled for as long as the button is pressed.

The stroke can be adjusted by using a hexagon socket screw key (5 mm), which

is inserted into the top of the actuator. The stroke spindle extends when the key is

rotated clockwise.

High functional reliability The actuator is overload protected, requires no limit switches and automatically stops

when the end stop is reached.

Combination valve/actuator Refer to the valve documentation for suitable valves, their permitted medium

temperatures and closing pressures.

Position indication The stroke is indicated mechanically on the bracket with tabs. The stroke range

adjusts itself automatically during operation.

Home position Factory setting: Actuator spindle is retracted.

When valve-actuator combinations are shipped, the direction of motion is set in

accordance with the closing point of the valve.

Direction of stroke switch When actuated, the direction of stroke switch changes the running direction in normal

operation. The direction of stroke switch has no influence on the emergency setting

position (POP) which has been set.

Emergency setting position (POP)

rotary knob

The rotary knob «Emergency setting position» can be used to adjust the desired

emergency setting position (POP). The POP range allways refers to the maximum

height of stroke of the actuator.

In the event of an electricity interruption, the actuator will move into the selected

emergency setting position (POP), taking into account the bridging time (PF) of 2 s

which was set ex-works.
