The actuators must be electrically connected in accordance with local regulations (refer
to «Connection diagrams»).
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»).
Mounting Instructions 4 319 5614 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»).

When commissioning the system, check wiring and the functions of the actuator.
Before testing the functioning of the SSC.., always check to ensure that the
actuator concerned is mounted on a valve (refer to «Equipment combinations»).
Calibrating the SSC619 without a valve connected causes the actuator to lock in
position 1. To recalibrate (after mounting on a valve), disconnect power and reset the
stroke manually from position 1 to 0 (refer to «Recalibration»).
The rotary knob can be used to drive the actuator into any position between 0 and 1. If a
control signal from the controller is present, this will take priority in determining the
position.
To retain the manually set position, unplug the connecting cable or switch off the rated
voltage and the control signal.
