General dangers of non-compliance with safety regulations
PSF-Ex actuators are built at state-of the art technology and are safe to operate. Despite of this, the actuators may
be hazardous if operated by personnel that has not been sufficiently trained or minimum instructed, and if the
actuators are handled improperly, or not used as per specification.
This may
•cause danger to life and limb of the user or a third party,
•damage the actuator and other property belonging to the owner,
•reduce safety and function of the actuator.
To prevent such problems, please ensure that these operating instructions and this chapter in particular have been
read and understood by all personnel involved in the installation, commissioning, operation, maintenance and repair
of the actuators.
Basic safety notes
•The actuators may only be operated by skilled and authorized operating personnel.
•Make sure to follow all security advices mentioned in this manual, any national rules for accident prevention, as
well as the owner´s instructions for work, operation and safety.
•The isolating procedures specified in these operating instructions must be followed for all work pertaining to the
installation, commissioning, operation, change of operating conditions and modes, maintenance, inspection,
repair and installation of accessories.
•Areas that can be under voltage have to be isolated before working on them.
•When installing the actuators, observe IEC/EN60079-14.
•Ensure that the actuators are always operated in faultless condition. Any damage or faults, and changes in the
operational characteristics that may affect safety, must be reported at once.
Danger signs
The following danger signs are used in this operating manual:
Caution! There is a general risk of damage related to health and/or properties.

Danger! Electrical voltages are present that may lead to death. Life threatening risks may occur
due to electrical voltages!
Danger! This sign warns of hazards posing a risk to health. Ignoring these instructions can lead
to injuries.
Attention! Observe precautions for handling. Electrostatic sensitive devices.
Other notes
•The motor surface temperature may rise when maintaining, inspecting and repairing the actuator immediately
after operation. There is a danger of burning the skin!
•Dust deposits > 5 mm must be removed!
•The cover may only be opened in an explosion-free environment! When working in hazardous areas, the
European standards EN 60079-14 "Erection of electrical installations in potentially explosive atmospheres" and
EN 60079-17 "Testing and maintenance of electrical installations in potentially explosive atmospheres" must be
observed.
•Always consult the relevant operating instructions when mounting PS-S accessories or operating the actuator
with PS accessories.
•Connections for signal in- and output are double isolated from circuits that can be under dangerous voltage.
2. Usage as per specification
•The actuator PSF-M-EX is a stationary installed device for use in Ex zone 1, 2, 21 or 22. The actuator PSF-M-EX is
not suitable for use in zone 0 and zone 20.
•The electrical data shown on the type plate as well as the unit category for the place of use must be observed.
•The operator of an electrical system in a potentially explosive atmosphere must keep the equipment in proper
condition, operate it properly, monitor it and carry out maintenance and repair work. See also IEC/EN 60079-17 /
IEC/EN 60079-19.
•The units must be installed in such a way that the risk of electrostatic charging is minimised. The risk of
electrostatic charging depends on the installation location, if necessary the risk can be minimised e.g. by
protecting against direct air flow or monitoring the ambient humidity, for cleaning use a damp cloth.
•The actuators PSF-EX are built exclusively for use as electric valve actuators. They are intended for assembly with
valves and their motorised actuation.
•Any other use is considered to be non-compliant and the manufacturer cannot be held liable for any damage
resulting from it.
•The actuators can only be used within the limits laid out in the data sheets, catalogues and other documents.
Otherwise, the manufacturer cannot be held liable for any resulting damage.

5. Function
The actuator PSF-M-EX is designed for use as an electric valve actuator with emergency handwheel. The actuator
columns are used for mounting on the valve. Depending on the valve design, a rod lantern or a special valve
mounting plate is required.
The torque generated by a brushless DC motor (BLDC) is transmitted to a spindle nut via a multi-stage spur gear. The
spindle nut converts the delivered torque into an axial force via a spindle. The resulting linear stroke movement is
transmitted to the valve spindle via a coupling piece.
The actuator stroke is detected and controlled by a linear 12-bit HALL sensor.
Emergency actuation of the actuators in the event of a power failure is possible via the handwheel.
The electrical connection is made via terminal strips in the drive.
6. Manual operation and setting of the DIP switches
6.1 Setting the actuators during commissioning (cover open)
When commissioning the actuators, the cover must be opened. The cover may only be opened in non-hazardous
areas and in a dry environment (see chapter 8).
For actuation of the actuator during adjustment work (valve assembly and end position adjustment), an electrical
manual override by means of a pushbutton is provided (for operation, see section 10.3).
Programming of the controls (DIP switch) is possible in the de-energised state (see chapter 10.1). To do this, first
loosen 4 fastening screws of the upper cover of the Ex d control housing, then the upper cover can be removed from
the Ex d control housing. The upper cover of the Ex d control housing must not be damaged in the area of the joint
gap when removing it.
The upper cover of the Ex d control housing must be installed taking into account the position of the push button
and the light guide (see figure 3). The tightening torque for the Ex d cover screws is 6 Nm, minimum quality of the
screws 8.8.
The operating status (status display LED in the Ex d control housing) is indicated by a light guide in the Ex housing
(see chapter 10.4).

The electrical connection of the drives is made via the terminal strip. For this, the wiring diagram must be observed
(see chap. 9.2).
Figure 1: Manual operation and setting of the DIP switches
6.2 Setting the actuators during commissioning (cover closed)
For actuation of the actuator during adjustment work in potentially explosive atmospheres (end position
adjustment), an electrical manual override by means of a push-button is provided in the cover (for conditions see
chapter 10.3). To reach the manual override, the screw plugs must be opened. The operating status (status display
LED in the Ex d control housing) is indicated by a sight glass in the cover (see figure 4) (see chapter 10.4).

The cover may only be opened in non-hazardous areas and only in a dry environment.
Attention! Observe precautions for handling.
•Ground the actuator.
•Before opening the cover, touch grounded housing parts.
9. Electric supply
9.1 Safety instructions
Before connecting to the mains, ensure that the mains supply is isolated and secured
against an accidental switching-on.
Remove the cover of the actuator in order to connect the electric supply (see 8.).
The mains connecting cables must be suitably dimensioned to accept the max. current requirement of the actuator.
The yellow-green coloured cables may only be used for connecting to earth.
When you insert the cable through the drive cable connector, ensure that the max. bending radius for the cable is
observed.
PSF-M-EX electric actuators do not have an internal electrical power switch. A switch or power mains switch must be
provided in the building installation. It should be positioned closely to the device and be easily accessible for the user
and shall be labelled as the mains isolator switch for the actuator.
The building installation must also provide power surge trips or fuses corresponding to standard IEC 60364-4-41 with
protection class I resp. protection class III (24 VAC / 24 VDC) for the actuator connections.
Please protect all of the power supply and control cables in front of
the terminals mechanically by using suitable measures against
unintentional loosening. Never install the power supply and the
control cables together in one line but instead please always use
two different lines.
Open:
Loosen the screws by using a screwdriver and unscrew
them entirely out of the gear casing. The screws are
protected against loss. Remove the cover carefully so as
not to damage the seal.
Close:
Put the cover on the gear casing and press down slightly.
Tighten the screws gently and then crosswise. It must be
ensured that all screws are tightened firmly to guarantee
protection against ingress of water and dust in
accordance with EN 60529 to IP65. The tightening torque
for the Ex e/t cover is 3 Nm.

10.4 Automatic commissioning (s. chapter 10.2)
•Ensure secure connection between valve and actuator.
•To start the automatic commissioning push button B2 minimum 7 seconds.
-Option 1: If adjusted “open with force –close with force”, the actuator will drive to the final open valve
position via force, and back to the final closed valve position.
-Option 2: If adjusted “open with calibrated stroke” (20/30/40 mm), the actuator will store the lower position
and the stroke is calculated according to the settings. If the possible travel is smaller than the preset stroke,
the operating stroke will be automatically reduced to the max. possible resulting value.
•After successful commissioning, the green LED is flashing 7 times.
•Push button B1 to return to normal operation.
•After successful commissioning, check the found or adjusted stroke by comparing the set value and the valve
position.
•In case of unsuccessful commissioning the green LED is flashing quickly. Please check valve mounting.
•For commissioning a stroke of at least 1 mm in direction “close with force” is required before the actuator has
reached its mechanical stop. Furthermore, the actuator must be able to perform a stroke of at least 5 mm.

•Press the handwheel towards the housing: the motor is deactivated.
•Keep the handwheel pressed and turn it:
oto the left: the valve spindle moves downwards.
oto the right: the valve spindle moves upwards.
•Release the handwheel: the handwheel is inoperative, after 5 seconds the motor is reactivated.
11. Operation
The operator of an electrical system in a potentially explosive atmosphere must keep the equipment in proper
condition, operate it properly, monitor it and carry out maintenance and repair work. See also IEC/EN 60079-17 /
IEC/EN 60079-19.
During operation, all internal parameters, such as the required motor torque and the current position, as well as the
operating states of the drive are permanently monitored. This ensures that the actuator is positioned with optimum
accuracy and that the valve is always closed correctly.
Cut-off in end positions
Depending on the setting of the DIP switch S2.1, the end position switch-off takes place in operation in one end
position at the position found/selected, in the other end position by force. (s. chapter 10.2).
12. Commissioning
•Before the first commissioning, the equipment must be checked for its suitability in the
corresponding zone on the basis of its marking. The values indicated on the type plate and in
the applicable documents must not be exceeded. Open the cover (s. chapter 8.), put the
actuator on the valve (see chapter 7.), connect the electric supply (s. chapter 9.).
•Open the cover (see chap. 8), place the actuator on the valve (see chap. 7), make the electrical
connection (see chap. 9). (see chap. 9).Perform automatic (s. chapter 10.5) or manual
