Function / mechanical design When the actuator is driven by DC 0…10 V control voltage or by a 3-position signal, it produces a stroke which is transmitted to the valve stem. The description of operation in this document applies to the valve versions which are fully closed when de-energized (NC valves). 3-position control signal SSB31../SSB81.. • Voltage at Y1: • Voltage at Y2: • No voltage at Y1 and Y2: DC 0...10 V control signal SSB61..

Notes The actuators must be electrically connected in accordance with local regulations (refer to «Connection diagrams»), page 8. Engineering Caution Regulations and requirements to ensure the safety of people and property must be observed at all times! The permissible temperatures (refer to «Technical data», page 6) must be observed. The connecting cable of the actuator may come into contact with the hot valve body, provided the temperature of the valve body does not exceed 80 °C. SSB 31.1.. and SSB81.

Manual override A 3 mm hexagonal socket wrench can be used to move the actuator to any position between 0 and 1. If a control signal from the controller is present, then this takes priority in determining the position. Note To retain the manually set position, unplug the connecting cable or switch off power and the control signal.
