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

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
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).

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.

6. Manual operation
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.
Figure 4: Manual operation
Do not exceed the adjusted electrical stroke
limits by using the hand wheel
The mechanical stop must be set
accordingly to protect the valve.
If you don’t observe this warning, the
electrical feedback setting will change!
The actuators are supplied with loose enclosed
crank. Mount the crank according to figure 3.

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.
8. Setting of the mechanical stop
There are two adjustable screws installed for setting the mechanical limit of the angular travel.
When setting the mechanical end positions, only the handwheel may be used. Do not
operate the actuator electrically.
Remove the protection cap (, item 3) from either stop screw.
Unscrew both stop screws anti-clockwise by approximately 5 turns.
Move the actuator to the closed position by turning the handwheel clockwise.
Turn the stop screw for closed position (, item 1) to the stop.
Move the actuator to the open position by turning the handwheel anti-clockwise.
Turn the stop screw for open position (, item 2) finger tight.
Screw on the protection cap onto the stop screw.

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 conform 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.
With protective low voltage 24 VAC the open motor phase can produce voltages
between 30-35 V due to motor generated induction voltage.
