Page 3: Symbols And Safety
1. Symbols and safety General dangers of non‐compliance with safety regulations PS‐AMS PSQ 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. 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 ... -
Page 4: Usage As Per Specification
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. 2. Usage as per specification PS‐AMS PSQ 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. ... -

Page 6: Operating Principle
5. Operating Principle The quarter‐turn actuators PS‐AMS PSQ are designed for the use as electric valve actuators. Mounting to the valve is done by a mounting flange as per ISO5211, plus an exchangeable drive bushing with an inside contour as per the valve shaft. Mechanical power is created by a 24 volts DC‐motor which is controlled from the electronics via pulse width modulation (PWM). Absolute encoded feedback comes from a precision potentiometer. The motor torque is transmitted through a reducing spur gear to a planetary gear set. Output is a centre gear with a multi‐toothed inner profile to accept the drive bushing. During power failure and adjustment work the actuators can be emergency‐operated via the handwheel (see chapter 6. Manual Operation) except when using the fail‐safe unit PSCP. 6. Manual Operation A handwheel is provided to operate the actuator in case of power failure or for valve adjustment. PS‐AMS PSQ actuators are supplied with handwheel loosely added. Before operation it has to be fitted as shown below. figure 3: Mounting the handwheel ... -
Page 7: Mechanical Mounting
Caution! The handwheel should not be used in ongoing motor operation, as the actuator tries to compensate the deviation in position, depending on the operating mode selected. If a fail-safe unit type PSCP (option) is installed, the handwheel can’t be used, as the actuator drives back to the failsafe position. 7. Mechanical Mounting 7.1 Safety Note Beware of mechanical hazards due to electrically powered actuator components! With the actuator powered electrically, operating the unit holds the danger of crushing your fingers, damaging the actuator and/or the valve. -

7.3 Valve Mounting PSQ2003/2803AMS The PS‐AMS PSQ 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 (already pre‐mounted). Use the position indicator at the gearbox to ensure the correct position of the actuator. Adapt it to the valve position by handwheel. In the best case, the position of the valve should be open or closed during mounting. Drive the actuator in the same end position manually. If the gearbox and actuator are in the same position, mount the actuator on the valve (if necessary, mount the adaptation of the valve shaft on the 55 mm double square first). Adapt the accurate mounting position by handwheel to insert the screws in the mounting flange. Tighten the screws in a diagonal sequence. 8. Electrical Connection 8.1 Safety Note When performing electric work on this unit, the local accident prevention regulations must be followed. Observe EN 60204‐1 (VDE 0113 part 1) to ensure human safety, integrity of the assets as well as the proper functioning of the unit. Electric supply lines must be dimensioned for the peak current of the unit and comply with IEC 227 and IEC 245. Yellow‐and‐green coded cords may only be used for connection to protective earth. When leading wires through the cable glands on the actuator, their minimum bending radius has to be considered. The electric actuators PS‐AMS PSQ are not fitted with an internal electric isolator, hence a switching device or circuit breaker must be integrated in the facility. It should be installed close to the actuator and should be easy to access for the user. It is important to mark the circuit breaker as this actuator‘s isolator. Electric installations and over‐current protection devices must be conform to the standard IEC 364‐4‐41, protective class I resp. DIN IEC 60364‐4‐44 according to the 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 ... -

8.3.2 Input Terminals 8.3.2.1 Set‐Value Terminals 1 through 3 are used to receive a parameterisable modulating set‐value for control operation within the range of 0‐20 mA or 0‐10V. 8.3.2.2 Sensor Feedback for Process Controller (optional) Terminals 15 through 17 (main board) resp. 10 through 12 (terminal box) are used to receive a process sensor‘s feedback to the ‐ optional ‐ process controller, in the parameterisable range of 0‐20 mA or 0‐10 V. Caution! The following binary input terminals (8.3.2.3 & 8.3.2.4) have priority over the modulating set‐value. If the actuator is parameterised for modulating service, these set‐value settings are disregarded in case a binary signal is applied. Only after disconnection of the binary signal the actuator will reposition according to the set‐ value applied. 8.3.2.3 Binary Input Terminals 9 through 11 (main board) resp. 17 through 19 (terminal box) are for binary open/close signals. Standard voltage level is 24 V to 230 V; see wiring diagram. The actuator is then driven in 3‐point service. 8.3.2.4 Fail‐safe port for Binary Input (optional) The fail‐safe port of the terminals 12 and 13 (main board) resp. 25 and 26 (terminal box) allows to drive the actuator to a parameterised safety position by applying a voltage of 24 V to 230 V. 8.3.3 Output Terminals 8.3.3.1 Active Position Feedback Active position feedback is adjustable within the range of 0‐20 mA or 0‐10 V.

Page 16: Operation
10. Operation All internal parameters, like required motor torque, actual position, functional status, etc., are being permanently monitored during operation of the actuator PS‐AMS. This ensures that the actuator positions with optimum accuracy, and closes the valve always tight. Deviations can be read out via communication software PSCS or via local control PSC.2 (see respective instruction manuals), or can be displayed to the control room using the fault indication relay. This provides maximum safety of the process. Cut‐offs of the PS‐AMS actuators can be adjusted to meet the valve function in an optimum way by using the communication software PSCS (using a special interface cable, or optionally Bluetooth connection). This will result in different behaviour of the actuator. In case a position is surpassed or not reached, this can be read out via the Fault Indication Relay or via the communication software PSCS. 10.1 Cut‐off by Force / Torque The actuator delivers the programmed maximum force / torque each time when driving to this end position. If the closing point inside the valve dislocates, e.g. when a seat gasket wears, then the actuator will drive further in its possible actuation range to try to reach the programmed force / torque. 10.2 Cut‐Off by Position automatically In normal operation, the actuator will stop at the position which was found at a mechanical stop in the valve or the actuator during Automatic Commissioning. If the closing point inside the valve dislocates, the actuator will NOT follow this dislocation but it will always stop at the point initially found. 10.3 Cut‐Off by Position In normal operation, the actuator will stop at the point which was defined by Manual Commissioning. This position is not depending on any mechanical stop inside valve or actuator. 11. Commissioning The actuator is shipped in the „not commissioned“ condition with the green LED flashing slowly. There will be no response to any input (set value or open/close signal). To make the actuator operational, it has to be commissioned to a valve. Depending on the type of cut‐offs programmed (see 10.1), there are two ways to do commissioning: ‐ Automatic commissioning is done if at least one of the cut‐offs is set to be “by force/torque” or “by position automatically”. ‐ Manual commissioning has to be made in case both cut‐offs are “by position”, either via software PSCS or via control box PSC.2. Caution! Electrical operation of the actuator is allowed only after mounting to a valve! ... -
Page 17: Automatic Commissioning
11.1 Automatic Commissioning This is performed if at least one of the cut‐offs is set to be “by force/torque” or “by position automatically”. During automatic commissioning the actuator goes through the full programmed valve stroke / angle automatically. Parameters specific to the valve are being measured and calculated values are permanently stored in the actuator. At the same, set value and position feedback range are scaled. To enable Automatic Commissioning, a mechanical stop is required in at least one end position (usually the closed position) of the valve. This mechanical stop can be either given by design of the valve, or it may be adjusted by the stop screws of the actuator (only when cut‐off “by position automatically“ is programmed). 11.1.1 Adjusting the Mechanical Stops PSQ103‐1503AMS Shown is the adjustment of a mechanical stop in closing direction for a valve closing clockwise. When adjusting a mechanical stop, drive the actuator only by handwheel, not electrically! Remove the protection cap (figure 22, item 3) from either stop screw. Unscrew both hexagon sockets anti‐clockwise by approximately 5 turns. Move the actuator to the closed position by turning the handwheel clockwise. Turn stop screw for closed position (figure 22, item 1) to the stop. ... -

The actuator will now travel through the full valve angle! ... -
Page 19: Additional Information
11.1.5 Additional information Note If the actuator is stalled during the automatic commissioning run BEFORE reaching a desired position‐dependent cut‐ off, it will then store the so‐obtained stroke. Note If, as a result of automatic commissioning, no force/torque limit is found, or if a stroke below the minimum allowed stroke (10° in standard version) is found, the commissioning run will be aborted. The actuator returns to the “not commissioned” condition (i.e. green LED flashing slowly), even if the actuator had been initialized correctly before that. Note Automatic commissioning can be started via software PSCS ‐> See relevant operation manuals Caution! ... -
