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
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 18: Manual Commissioning (See Also Chapter 12.3)
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 60079-17/IEC 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 20: Valve Curve

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. -
Page 22: Decommissioning And Disposal
16. Decommissioning and disposal Disconnect the mains connection and secure it against accidental reactivation. Open the hood. Remove external connections. Remove the actuator from the valve. Disposal The actuator is considered waste from electrical and electronic equipment and shall not be disposed of as household waste. - Page 23 Our representatives: Italy India PS Automazione S.r.l.
