Description of operation
Depending on the type of connection (see connection diagram), the actuator can be used as a contin-
uous (0...10 V or 4...20 mA), 2-point (OPEN/CLOSE) or a 3-point actuator (OPEN/STOP/CLOSE).
The positioning time of the actuator can be set with the S1 switches according to the respective re-
quirements. Using switch S2, the direction of operation can be changed.
In the end positions (valve limit stop or when the maximum stroke is reached) or upon overload, the
electronic motor cut-off (no limit switch) responds and turns off the motor.
The external crank handle enables manual positional setting. After the crank handle is folded back,
the actuator moves to the target position again (without initialisation). When the crank handle is folded
out, the actuator remains in this position.
Intended use
This product is only suitable for the purpose intended by the manufacturer, as described in the “De-
scription of operation” section.
All related product regulations must also be adhered to. Changing or converting the product is not ad-
missible.
Engineering and fitting notes
The concept of a brushless DC motor/electronics ensures electrical parallel operation of up to five ac-
tuators of the same type.
The valve is mounted directly on the actuator and fixed with screws (no further adjustments are re-
quired). The actuator is connected with the valve spindle automatically. As delivered ex works, the ac-
tuator spindle is in the middle position.
As delivered ex works, the actuator spindle is in the middle position.
Condensate, dripping water, etc. must be prevented from entering the actuator along the valve spin-
dle.
The housing contains two break-out cable inlets for two metric plastic cable glands M20×1.5, which
are broken out automatically when the cable inlet is screwed in.
If the cable resistance is > 1.5 Ω, the ground should be separated from the power supply and the sig-
nal if possible.
The cross-section of the power cable must be selected based on the cable length and the number of
actuators. With five parallel actuators and a cable length of 50 m, a cable cross-section of 1.5 mm
2
and a line resistance of > 1.5 Ω must be used (power consumption of the actuator × 5).
According to building installation regulations, the lines must be protected from overload or short cir-
cuit.
)
Note for UL and CSA applications:
In the United States, the installed lines and cross-sections which are to be connected by the customer
must comply with the requirements of NFPA70 (NEC), and in Canada they must comply with the require-
ments of the standard C22.1-12 (CE Code).
The coding switches and the SLC interface for CASE Drives are accessible via an opening in the con-
nection area of the actuator. Conversion and operation is possible while the actuator is energised.

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)

With coding switch S3, the characteristic of the valve/actuator combination can be adjusted. An
equal-percentage characteristic can only be generated when the actuator is used as a continuous ac-
tuator.
Initialisation and feedback signal
The actuator initialises itself automatically when it is connected as a continuous actuator (not in 2-/3-
point mode).
When a voltage is applied to the actuator for the first time, the actuator first moves to the first and
then to the second valve limit stop, or to the internal actuator stop. The two values are recorded and
stored by the absolute distance measurement system. The control signal and the feedback are adap-
ted to this effective stroke.
After initialisation, the actuator goes to every valve stroke between 0% and 100%, depending on the
control voltage.
In case of a power failure or the removal of the power supply, no re-initialisation needs to be carried
out. The values remain saved.
If the initialisation is interrupted, the initialisation is started again when the voltage is re-applied.
You trigger a re-initialisation by switching coding switch S8 from OFF to ON or vice versa.
When the process is triggered, the LED flashes green.
During initialisation, the feedback signal is inactive or equal to the value “0”. The initialisation is car-
ried out with the shortest positioning time. The re-initialisation is only valid when the whole process is
complete.
If a stroke change is carried out, a re-initialisation must be triggered so that the new stroke can be
adapted.
If the valve actuator detects jamming, it reports this by setting the feedback signal to 0 V after approx.
90 s. During this time, the actuator continues to try to overcome the jamming. If the jamming can be
overcome, the normal control function is activated again and the feedback signal is restored.
With 2-point or 3-point control without a feedback signal, no initialisation is performed.
Continuous control can also be implemented with a 230 V power supply with the external accessory
0500570003 “230 V module”. You must ensure that the neutral wire of the controller is connected to
the control voltage. The neutral wire of the power supply may only be used for the 230 V module.

Forced operation (in continuous mode)
Forced operation is activated via coding switch S5.
To use this function, an external on/off controller must be attached to terminal 6. The on/off controller
functions as normally-closed contacts.
If the on/off controller opens the electrical circuit, the actuator spindle moves to the end position de-
fined by coding switch S6.
Forced operation can be used only in continuous mode.
2-/3-point operation using the reset signal
If terminal 6 is continuously connected to the power and coding switch S5 is set to OFF, the feedback
signal 0...10V can be used.
When this function is used, the actuator automatically performs an initialisation during commissioning.
Split-range module, accessory 0500420002
Starting point U0 and control span U can be set with the potentiometer. In this way, several control
units can be operated in sequence or cascade by the control signal of the controller. The input signal
(partial range) is amplified into an output signal of 0...10V.
CASE Drives PC tool, accessory 0510220001
CASE Drives allows you to set and read the actuator parameters on site. The connection is via a seri-
al port on the PC (laptop) and a socket on the actuator. The set consists of: The software including
installation and operating instructions, fitting instructions, connection plug, cable (1.2 m long) and in-
