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.
