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»,
page 2).
Calibrating the SSC61 or SSC61.5 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», page 3).
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. Due to the reset function, the SSC61.5 will first travel to
position 0 and can then be driven manually to the required position.

After manual override with the rotary knob the positioning signal and the stroke
synchronize autonomously, if the positioning signal is once > 9.7 V or < 0.3 V.
When servicing the actuator:
· Switch off power
· If necessary, disconnect the terminals
· The actuator must only be commissioned with a correctly mounted valve in place!
The SSC.. actuators cannot be repaired. They must be replaced as a complete unit.
