When the AC / DC 24 V supply is applied for the first time, the actuators calibrate
themselves independent of the control signal. In this process, the actuator drives the
valve to the mechanical end stops and stores the associated positions permanently in the
form of electronic values. The positioning signal is only active on completion of this
calibration process. Calibration takes about 60 seconds.
The SSC61.5 only performs self-calibration when the charging process is completed.
If the calibrated actuator is used with
some other valve (e.g. a replacement
valve), it must be recalibrated.
1. Unscrew screws
2. Remove cover
3. Connect the 2 contacts behind the
slot for about 1 second.
The calibration can only be made correctly if the actuator is fitted to a valve (refer to
«Equipment combinations», page 2).

Notes
The actuators must be electrically connected in accordance with local regulations (refer
to «Connection diagrams», page 7).
Regulations and requirements to ensure the safety of people and property must
be observed at all times!
The permissible temperatures must be observed (refer to «Technical data», page 5).
Mounting Instructions 74 319 0260 0 are enclosed with each pack.
Assembly is made with the coupling nut; no tools or adjustments are required. The
actuators should be installed so that they are initially in position 0 (also refer to «Manual
override», page 4).
