Mechanical Stroke Setting

6 Mechanical Stroke
Setting
The stroke of the electrical
actuator (maximum stroke 15 mm)
must be adjusted after having
mounted the valve stroke.
This avoids an „empty“ stroke of
the actuator and a possibly unsta-
ble control.
Prior to mounting, please observe:
DANGER: High voltage !
Danger to life or injury in case of
unqualified handling. Actuator
can be damaged.
It is absolutely necessary to
disconnect power supply prior
to setting the stroke.
