8. Removing the Cover
Please Observe the Label on the Cover of the Actuator.
9. Setting of the Limit Switches
Only for deliveries without valves!
Two adjustable limit switches are installed to limit the stroke of the actuator, and cut-off the motor current in the
relative direction. (see 9.1 ff) Additional limit switches are free of voltage and serve to indicate the valve position.
Most motors have a thermal switch, depending on the actuator type, to cut off the current in both directions when a
maximum temperature is reached. The cover must be removed in order to set the limit switches.
