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.
