    General dangers in case of non-observance of the safety instructions The PSF-Ex actuators are built according to the latest state of the art and are operationally safe. Nevertheless, hazards can arise from the actuators if they are not used by trained or at least instructed personnel and/or are used improperly or for purposes other than those for which they are intended.

  • Page 6: Intended Use

    5. Intended use  The type PSF-EX actuator is a fixed installed device for use in Ex zone 1, 2, 21 or 22. The type PSF-EX actuator is not suitable for use in Zone 0 and Zone 20.

  • Page 7: Special Conditions

     Assembly/disassembly, operating and maintenance work may only be carried out by suitable skilled personnel familiar with the work. All generally applicable legal regulations and other binding guidelines for work safety, accident prevention and environmental protection must be complied with. ...
  • 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 (hood open) When commissioning the actuators, the hood must be opened. The hood may only be opened in non-hazardous areas and only in a dry environment (see chapter 10 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 12.3).

  • Page 10: Setting The Actuators During Operation (Hood Closed)

    8.2 Setting the actuators during operation (hood 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 hood (for conditions see chapter 12.3). To reach the manual override, the screw plugs must be opened.

  • Page 13: Electric Supply

    Unused entries must be closed by suitable blanking elements. As the PSF-Ex electrical actuators do not have an internal electrical disconnect device available, a switch or circuit breaker must be provided in the building installation. This must be located in the vicinity of the device, easily accessible to the operator and must be identified as a disconnect device for the device.

    12.6 Manual commissioning (see also chapter 12.3)  Check that the gland between the valve and the actuator is secure.  To activate the individual calibration, press button B1 > at least 7 seconds.  The actuator can be moved manually with buttons B1 and B2 until the desired open-end position of the valve is reached.

  • Page 19: Operation

    13. 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: Maintenance And Servicing

    15. Maintenance and servicing The actuators are maintenance-free under the operating conditions specified in the data sheet. The gearboxes are lubricated for life and do not require relubrication. Attention! During maintenance and servicing, the actuator must not be operated electrically. Personnel carrying out work and maintenance and servicing must be skilled and familiar with the work.
