 Always observe the relevant operating instructions when fitting PS 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 PSQx03 quarter turn actuators are exclusively designed as electric valve actuators. They are meant to be
mounted on valves for motor operation.
 Any other use is considered to be not in accordance to standard specification, and the manufacturer cannot be
held liable for any damage resulting from it.
 The actuators may not be used outside the limits laid out in data sheets, catalogues and order documentation.
Otherwise the manufacturer cannot be held liable for any resulting damage.
 Usage as per specification includes the observance of the operating, service and maintenance conditions laid
down by the manufacturer.
 Not to be regarded as usage as per specification are mounting and adjustment of the actuator, and servicing.
Special precautions have to be taken while doing this!
 The actuators may only be used, serviced and repaired by personnel that are familiar with them and informed
about potential hazards. The specific regulations for the prevention of accidents have to be observed.
 Damages caused by unauthorized modifications carried out on the actuators are excluded from the
manufacturer's liability.
 Supply voltage may be switched on only after properly closing the main cover or terminal box.
3. Storage
The following must be observed with regards to proper storage:
 Only store the actuators in ventilated, dry rooms.
 Store the actuators on shelves, wooden boards etc. to protect them from soil moisture.
 Cover the actuators with plastic foil to protect them from dust and dirt.
 Protect the actuators against mechanical damage.
4. Operational conditions
 The standard actuators can be operated at ambient temperatures from -20°C to +80°C
 Ambient temperature range for modulating duty is from -20°C to +60°C.
 The operating modes correspond to IEC 60034-1, 8: S2 for 3-point operation, and S4 for control duty (For
protection against moisture and dust, the actuator enclosure rating is IP67 / IP68 according to EN 60529.) To
ensure the protection rating, the cover must be fitted correctly and the holding screws tightened crosswise. The
cable glands must be suitable for the cables and correctly fitted to the actuator.
 When installing the actuators, leave enough space to permit cover removal (Figure 1: Installation dimensions).
 Any installation position is allowed except "cover pointing downwards" (Figure 2: Installation position).

5. Function
The electric quarter-turn actuators series PSQx03 are designed to operate valves with 90° motion. The PSQ actuators
are provided with a mechanical interface according to ISO 5211 for valve mounting. The motor torque is transmitted
via a spur gear onto the sun wheel of a „Wolfrom“-gear. The rotating output wheel of the „Wolfrom“-gear holds a
removable drive bush to connect the actuator with the valve stem. Two adjustable position switches are limiting the
electrical motion in both directions by interrupting the motor current or control circuit when reaching the adjusted
position.
The 90° motion is mechanically adjustable by +/- 5° by means of two stop screws. Torque switches are installed for
each direction.
The handwheel does allow comfortable manual operation in case of power failure or for commissioning. The
handwheel is idle when the motor is operating the actuator, but engaged in any position without clutching or
declutching.
Electrical wiring is done to a terminal block under the actuator cover.
6. Manual operation
The actuators are supplied with a loosely enclosed handwheel. Mount the handwheel and the crank according to
Figure 3:
Figure 3: Handwheel assembly
The handwheel does provide manual operation in case of power failure or commissioning (valve mounting and
setting of end positions). It is idle when the motor is operating and always ready for operation without clutching or
declutching.
Figure 4: manual operation PSQ103-1503 Figure 5: manual operation PSQ2003/2803
Do not exceed the adjusted electrical stroke limits by handwheel.
The mechanical limits must be set accordingly.
Failure to observe this warning will change the electrical feedback setting!

7. Valve mounting
7.1. Valve mounting PSQ103-1503
The PSQx03 actuators are provided with flanges according to ISO 5211 for valve mounting. Connection to the valve
shaft is made with an exchangeable drive bush.
Starting position: drive bush is already pre-installed in the actuator
 Ensure the correct position of the actuator by position indicator
and adapt it to the position of the valve by handwheel. Ideally,
the end position of the valve should be open or closed. Drive the
actuator in the same end position by handwheel.
 If the positions of valve and actuator are adapted, put the
actuator with the drive bush on the valve.
 Adapt the accurate mounting position by handwheel to insert
the screws in the mounting flange. Tighten the screws in a
diagonal sequence.
Starting position: drive bush is delivered separately and not yet
pre-installed in the actuator
 Put the drive bush on the valve shaft first.
 Follow the instructions of the pre-installed drive bush above.
However, please note: The drive bush is not installed in the
actuator for mounting on the valve shaft. Instead, the drive bush
is already mounted on the valve shaft as a unit. Put the actuator
on this unit.
7.2 Valve mounting PSQ2003/2803
The PSQx03 actuators are provided with flange F16 according to ISO 5211 for valve mounting. Connection to the
valve shaft is made with a 55 mm double square. Delivery of the actuator includes two components: the gearbox and
the actuator itself. They are mounted on the valve one after the other.
For valve mounting please ensure that the cover of the actuator is always closed in order to avoid
that components inside the actuator are damaged.
 Ensure the correct position of the gearbox by position indicator and adapt it to the valve position using a 22
mm spanner to turn the shaft of the gearbox. In the best case, the position of the valve should be open or
closed during mounting. If possible, drive the valve to one of the end positions manually. Drive the gearbox
in the same end position using the spanner.
 If the gearbox and actuator are in the same position, mount the gearbox on the valve (if necessary, mount
the adaptation of the valve shaft on the 55 mm double square first).
 Adapt the accurate mounting position with the spanner in order to insert the screws in the mounting flange.
Tighten the screws in a diagonal sequence.
 Put either (A) the actuator with the drive bush on the gearbox or (B) at first the drive bush and then the
actuator on the gearbox (see figure 6 for reference).
 Adapt the accurate mounting position by handwheel to insert the screws in the mounting flange. Tighten
the screws in a diagonal sequence.

(4 mm blade width) clockwise until the micro switch is heard to click.
 Drive the actuator away from either end position to release the stop screws.
 Turn both stop screws counter-clockwise by one turn.
 Replace protection caps (Figure 7, item 3) onto the stop screw holes after setting the position switches.
10. Setting the torque limit
There is one torque switch installed for each direction that cuts off the motor current when operated (single phase
motors).
The quarter-turn actuator is set and checked by the manufacturer in order to limit the actuator to the nominal
torque in both directions. The reduction of the maximum output torque is possible by setting the switch brackets, to
suit the specific requirements of the valve.
 Loosen the torque setting screws (Fehler!

z11. Electric supply
Before connecting to mains, ensure that the mains supply is isolated and secured against an
accidental switching-on.
The mains connecting cables must be suitably dimensioned to accept the maximum current requirement of the
actuator, and correspond to IEC 227 and IEC 245. The yellow-green coloured cables may only be used for connecting
to earth.
When inserting the cable through the cable connector, ensure that the maximum bending radius for the cable is
observed.
The PSQx03 electric actuators do not have an internal electrical power switch. Therefore, a power mains switch has
to be provided for installation. It should be positioned close to the device and be easily accessible to the user and
shall be labelled as the mains isolator switch for the actuator.
Electric installation as well as over-current and overvoltage protection devices must be conform to the standard DIN
IEC 60364-4-41, protective class I resp. protection class 3 (24 VAC/24 VDC) and also to the standard DIN IEC 60364-
4-44 according to the applied overvoltage category of the actuator.
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.
11.1 Wiring diagram
Figure 12 indicates the wiring diagrams for standard actuators. However, the wiring diagram inside the actuator
cover is relevant for the specific actuator. See the separate wiring diagram in the corresponding service instructions
for any set of accessories.

Figure 18: Electrical connection PE
Two adjustable position switches are installed to limit the stroke of the actuator, and cut-off the motor current in
the relative direction.
Most motors have a thermal switch, depending on the actuator type, to cut off the current in both directions when a
maximum temperature is reached (only at standard single phase power supply).
12. Commissioning
The electrical connection and commissioning with mains voltage applied may only be
carried out by trained specialist personnel!
Do not touch any connection lines during commissioning!
 Close the cover.
 Turning the handwheel, drive the valve to the middle position.
 Switch the setting signal briefly to OPEN and CLOSE and check that the actuator operates in the correct
direction. If necessary, reverse the setting signal for OPEN/CLOSE.
 Drive the actuator in either direction, using the setting signal until the position switch cuts-off. Check that the
position switch setting is correct. If necessary re-adjust the position switch (see chapter 9).
13. Service/maintenance
The actuators are maintenance-free if used under the operating conditions as established in the data sheet. The
gearboxes are lubricated for life and do not require further lubrication.
Caution !
During maintenance and repair the actuator must not be operated
electrically.
13.1 Cleaning
The actuators should be cleaned with dry cloth.

13.2 Spare parts
PSQx03 actuators are very robust functional units. In case of malfunction or damage of any component, spare parts
are available as per a separate spares price list. Please contact PS Automation GmbH or the appropriate
representative.
Damaged actuators can be returned to our plant in Bad Dürkheim, Germany, or to our representatives, for
evaluation of failures and repair.
14. Disposal
According to 2012/19/EU on waste electrical and electronic equipment (WEEE), the devices described
here must not be disposed of via municipal waste disposal companies.
If you are unable or unwilling to arrange for disposal by a specialist company, you may return the
equipment to the manufacturer, who will then ensure that the equipment is disposed of properly for a
flat fee.
15. Safety on Transportation
For transportation and storage all cable glands and connection flanges have to be closed to prevent ingress of
moisture and dirt. A suitable method of packaging is required for transporting to avoid damage of coating and any
external parts of the actuator. Remove the handwheel for transportation.
