 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
PSR-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
 PSR-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.
 Electrical wiring is done to a terminal block under the actuator cover.
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.
 Standard actuators may be operated at ambient temperatures from -25°C to +70°C.
 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, enclosure rating is IP65 (optionally IP67) according to EN
60529. To ensure this enclosure, the cover must be fitted correctly and the screws tightened cross wise
after opening. The hand wheel must be fitted to the hand wheel shaft. The cable glands must be
suitable for the wiring and correctly fitted to the actuator. To maintain the degree of protection IP65
(resp. IP67), cable glands M20x1,5 must be used which are suitable for the cable diameter.
 Space needed to remove the cover: 100 mm above the actuator

5
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.
4.1 Installation position
The actuator can be installed vertically or
horizontally or any position in between. The
actuator must not be installed with the cover
pointing downwards.

The electric quarter-turn actuators Series PSR-E are designed to operate valves with 90° angular motion
using the ON/ OFF mode. The PSR-E actuators are provided with a mechanical interface according to ISO
5211 for valve mounting. The motor torque is transmitted via spur gear, indirectly transmitted onto a
double square drive bush. This drive bush is used as a connecting piece between actuator and valve shaft.
The 90° rotation is adjustable mechanically +/- 5° in one end position. Two adjustable switches limit the
rotation in both directions, interrupting the motor current when reaching the adjusted end position.
The hand wheel allows manual operation in case of power failure and during adjustment (See pt. 6).
5. Manual operation
The hand wheel allows manual operation in case of power failure or during adjustments (Mounting or
positioning the valve). For manual operation, the hand wheel has to be pushed down against a spring.
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!
6. Valve mounting
The PSR-E actuators are designed with a mechanical interface according to ISO 5211 for valve mounting.
The gear contains an exchangeable drive bush to connect the actuator to the valve shaft.
 Check if the actuator flange suits the valve flange
 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

9. Electric supply
Switch mains off before starting to work!
Connect acc. to wiring diagram on the main frame.
Mains connection cables must be dimensioned suitably to accept the maximum current requirement of the
actuator and correspond to IEC 227 and IEC 245.
The yellow-green coloured cables may be used only for connecting to earth.
When you insert cables through the cable connector, ensure that the maximum bending radius for the
cables is observed.
PSR-E electric actuators do not have an internal electrical power switch. A switch or power mains switch
has to be provided therefore in plant installation. This should be positioned close to the device and easily
accessible to the user; it shall be labelled as the mains isolator switch for the actuator.
Plant installation must also provide power surge trips or fuses corresponding to standard IEC 364-4-41/ DIN
VDE 0100-410 with protection class 1 for the actuator connections.
9.1 Wiring diagram
Figure 9 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.
