1. Symbols and safety
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. Avoid personal or
material damages by observing applicable regulations and safety standards!
Other notes
The motor surface temperature may rise when maintaining, inspecting and repairing the actuator
immediately after the operation. There is a danger of burning the skin!
Always consult the relevant operating instructions when mounting 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.
General dangers of non-compliance with safety regulations
PSQ-E 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 at least
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 the safety regulations 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
Before opening the actuator cover, ensure that mains supply is isolated and prevented from unintended
re-connection.
Areas that can be under voltage have to be isolated before working on them.
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.

2. Usage as per specification
PSQ-E quarter turn actuators are exclusively designed to be used as electric valve actuators. They
are meant to be mounted on valves in order to run their motors.
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.
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 adjusting the actuator as well as
servicing. Special precautions have to be taken while doing this!
The actuators may only be used, serviced and repaired by personnel that is 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 only be switched on after the proper closure of the main cover or terminal box.
3. Storage
For appropriate storage, the following instructions have to be met:
Only store the actuators in ventilated, dry rooms.
Store the actuators on shelves, wooden boards, etc., to protect them from floor moisture.
Cover the actuators with plastic foil to protect them from dust and dirt.
Protect the actuators against mechanical damage.
4. Operating conditions
Actuators with synchronous motors can fluctuate by up to +/-20% in the actuating force with +/-10%
voltage fluctuation.
The standard actuators can be operated at ambient temperatures from -25°C to +70°C.
Ambient temperature range for modulating duty is from -25°C to +70°C.
The operating modes correspond to IEC 60034-1, 8 S2 for short cycle 20 min. S3/S4 control operation
1200 c/h – 25% ED at 25°C.
For protection against moisture and dust, the actuator enclosure rating is IP67 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).
Any installation position is allowed except “cover pointing downwards” (figure 2).

4.1 Installation position
Figure 2: Installation position
Outdoor usage:
When using actuators in environments with high
temperature fluctuations or high humidity, we
suggest a heating resistor to be fitted to prevent
the build-up of condensation within the enclosure.
5. Function
The electric quarter-turn actuators Series PSQ 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. Optionally, torque switches can be 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.

The mechanical stop must be set accordingly to protect
the valve.
If you don’t observe this warning, the electrical
feedback setting will change!
7. Valve mounting
The PSQ-E actuators are provided with a mechanical interface according to ISO 5211 for valve mounting.
The gear does contain an internal octagon SW22 to connect the actuator to the valve shaft.
Figure 5: Actuator flange
Check if the actuator flange suits the valve flange
If required, use standard adapters to adapt to the
valve shaft
Clean the surface of the connection components,
lubricate valve shaft slightly
Position the actuator on the valve
Tighten the screws in a diagonal sequence according
to the required torque
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.

The actuators are supplied with loose enclosed crank. Mount the
crank according to figure 3.
The handwheel does provide manual operation in case of power
failure or commissioning. It is idle when the motor is operating and
always ready for operation without clutching or declutching.

9.1 Setting of the internal limit switches
Ensure that the mains supply is secured against accidental switching-on!
The limit switches are pre-adjusted in the factory. An additional adjustment of the two lower switching
cams is normally not necessary. If you wish to adjust the limit switches yourself, please follow these
instructions:
Run the actuator by using the hand wheel in direction to the closed position until the required position
is reached.
Turn the cam of the CLOSE limit switch (Figure 9, Pos. D) with a suitable screw driver (4 mm blade width)
clockwise until you hear the micro switch click.
Run the actuator by using the hand wheel in direction to the open position until the required position is
reached.
Turn the cam of the OPEN limit switch (Figure 9, Pos. C) with a suitable screw driver (4 mm blade width)
counter-clockwise until the micro switch is heard to click.
Check the switching position and repeat the adjustment if necessary.

10. Electric supply
Switch mains off before starting to work!
Connect acc. to wiring diagram on the main frame.
The mains supply cords 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 PSQ-E electric actuators do not have an internal electrical power switch. A power mains switch has
therefore to be provided in the installation. This 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 conformed to the
standard DIN IEC 60364-4-41, protective class I and also to the standard DIN IEC 60364-4-44 according to
the applied overvoltage category of the actuator.

10.1 Wiring diagram
Figure 10 shows the standard electrical connections. However, the wiring diagram inside the actuator hood
is valid for the specific actuator. For any optional extras see the individual wiring diagram in the related
service instructions.
Two adjustable limit switches are installed to limit the stroke of the actuator, and cut-off the motor current
in the relative direction.
PE Earth connection on housing plate has to be connected!
Ensure that all connecting cables are stripped to the correct length so that they are
protected against electric shock.
11. Commissioning
Drive the actuator into an intermediate stroke position using the hand wheel.
Switch the setting signal briefly between OPEN and CLOSE and ensure that the actuator operates in the
correct direction. If necessary, reverse the setting signal for OPEN / CLOSE.
Drive the actuator, in both directions, using the setting signal until the limit switch cuts-off. Ensure that
the limit switch position is correct. If necessary re-adjust the limit switches.
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!
