Page 6: Intended Use
Notice of hazards The following hazard symbols are used in these instructions: Attention! There are general hazards that can lead to property and/or personal injury. Caution! Life threatening electrical voltages may be present! Danger! This symbol warns of an imminent danger to the health of persons. Failure to follow these notices may result in injury. -
Page 7: Special Conditions
• Mounting and adjustment of the actuator as well as its maintenance are not considered as intended use. Enhanced safety precautions must be implemented in such situations! • Assembly/disassembly, operating and maintenance work may only be carried out by suitable skilled personnel familiar with the work. - Page 8 Installation • The conductor must be connected carefully at the terminal points so that the individual wires are not damaged. The maximum connection data on the type plate and the applicable documents must be taken into consideration. • The device must be integrated into a suitable earthing or equipotential bonding system before commissioning, a connection part (4 mm²) is available for this purpose on the underside of the actuator.

Page 9: Manual Override And Setting Of The Dip Switches
8. Manual override and setting of the DIP switches 8.1 Setting the actuators during commissioning (cover open) When commissioning the actuators, the cover must be opened. The cover may only be opened in non-hazardous areas and only in a dry environment (see chapter 11 for instructions). To actuate the actuator during setting work (valve assembly and end position setting), an electrical manual override by means of a push button is available (for operation, see chapter 14.3). -
Page 10: Setting The Actuators During Operation (Cover Closed)
8.2 Setting the actuators during operation (cover closed) To actuate the actuator during setting work in potentially explosive atmospheres (end position setting), an electrical manual override by means of a push button is provided in the cover (for conditions see chapter 14.3). To reach the manual override, the screw plugs must be opened. -
Page 11: Valve Mounting
9. Valve mounting The PSF-Q-M-EX 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. •... -

Page 20: Operation
15. Operation The operator of an electrical system in a potentially explosive environment must keep the equipment in proper condition, operate it properly, monitor it and carry out maintenance and repair work. See also IEC/EN 60079- 17/IEC/EN 60079-19. During operation, all internal parameters, such as the required motor torque and the current position, as well as the operating states of the actuator are continuously monitored. -
Page 21: Valve Curve
15.2 Valve curve Switch position S2-10 can be used to select the relationship between the set value and the actuator position. Two curves are available. With the linear valve curve, the actuator position in % corresponds to the set value in %. The "Quick Opening Curve"... -
Page 22: Maintenance
17. Maintenance The actuators are maintenance-free if used under the operating conditions as designated 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. Personnel carrying out work and maintenance and servicing must be skilled and familiar with the work. -
Page 23: Decommissioning And Disposal
18. Decommissioning and disposal • Disconnect the mains supply and ensure that it is secured against an accidental switching-on. • Open the cover. • Remove external electrical connections. • Take off the actuator from the valve. Disposal For its disposal, the product should be treated as waste containing electrical and electronic equipment and should not be disposed of as household waste. - Page 24 Our representatives: Italy India PS Automazione S.r.l.
