Any device modification requires prior written consent of the manufacturer. 1.2 Range of application AUMA part-turn actuators SQEx/SQREx are designed for the operation of industrial valves, e.g. butterfly valves and ball valves. The devices described below are approved for use in the potentially explosive atmos- pheres in compliance with the classification (class, division) as specified on the name tag.
Safety instructions Potentially hazardous situation. Failure to observe this warning could re- NOTICE sult in property damage. Is not used for personal injury. safety alert symbol warns of a potential personal injury hazard. The signal word (here: DANGER) indicates the level of hazard. 1.4 References and symbols The following references and symbols are used in this manual: The term Information preceding the text indicates important notes and infor-...
Controls are required to operate or process the actuator signals. Actuators without controls can be equipped with AUMA actuator controls at a later date. For more information, please state our order number. The order number is avail- able on the tame tag.

Operation 7 Operation 7.1 Manual operation For purposes of setting and commissioning, in case of motor failure or power failure, the actuator may be operated manually. Manual operation is engaged by an internal change-over mechanism. Manual operation is automatically disengaged when motor is started again. The hand- wheel does not rotate during motor operation.

Signals (output signals) 9 Signals (output signals) 9.1 Feedback signals from actuator The switches can be provided as single switches (1 NC and 1 NO), as tandem switches (2 NC and 2 NO) or as triple switches (3 NC and 3 NO). The precise version is indicated in the terminal plan or on the order-related technical data sheet.
Commissioning (basic settings) 10 Commissioning (basic settings) 10.1 End stops in part-turn actuator The internal end stops limit the swing angle. They protect the valve in case of limit switching failure during motor operation and serve the purpose as limitation for manual operation via handwheel.
Commissioning (basic settings) 10.1.1 Set end stop CLOSED 1. Remove screw plug [3]. 2. Move valve to end position CLOSED with handwheel. 3. If the valve end position is not reached: Slightly turn setting screw counterclock- wise until valve end position CLOSED can be correctly set. Turning the setting screw [4] clockwise decreases the swing angle.
