)Note:
The actuators are not suitable for use
•in potentially explosive environments,
Specific standards such as IEC/EN 61508, IEC/EN 61511, EN ISO13849 and the like have not been
tak-en into account.
Local requirements regarding installation, usage, access, access rights, accident prevention, safety, dis-
mantling and disposal must be taken into account.
The housing must not be opened.
Outdoor installation
In case of installation outside buildings, the devices must also be protected from the weather.

Connection as 2-point valve actuator (24 V)
The OPEN/CLOSE activation is via two wires.
The actuator is connected to a permanent voltage via terminal MM and terminal 01.
When voltage (24 V) is applied to terminal 02, the actuator spindle extends into the end position.
After the voltage is switched off at terminal 02, the actuator automatically retracts into the base posi-
tion.
Terminal 03 may not be connected or touch other contacts. We recommend that you insulate these.
Connection as 3-point valve actuator (24 V)
If voltage is applied to terminals MM and 01 (or 02), the valve can be moved to any position.
If voltage is applied to terminals MM and 01, the actuator spindle retracts.
If the electrical circuit is closed on terminal MM and 02, the actuator spindle extends.
If there is no voltage on terminals 01 and 02, the actuator remains in the respective position until volt-
age is applied.
Terminal 03 may not be connected or touch other contacts. We recommend that you insulate these.
Connection to a control voltage (0...10 V or 4...20 mA)
The built-in positioner controls the actuator depending on controller’s output signal y. A voltage signal
(0...10 V) at terminal 03 serves as the control signal. Coding switch S4 can be used to switch to a
current input (4...20 mA). If there is voltage on terminals MM/01 and a rising positioning signal, the
actuator spindle extends. The direction of operation can be reversed with coding switch S2.
The starting point and control span are fixed. For setting partial ranges (only for voltage input), a split-
range unit is available as an accessory (see split-range unit function).
After the connection of the power supply and the initialisation, the actuator moves to every valve
stroke between 0% and 100%, depending on the control signal. Thanks to the electronics and the ab-
solute distance measurement system, no stroke is lost, and the actuator does not require periodic re-
initialisation.
If the control signal 0...10 V is interrupted in the direction of operation 1, the actuator spindle retracts
completely.
If the control signal 0...10 V is interrupted in the direction of operation 2, the actuator spindle extends
completely. This is true if the forced operation is switched off. (Coding switch S5 OFF)
