6.1.1 Handwheel
In case of a power failure the actuator can be adjusted using a handwheel.
WARNING
Danger of injury from the handwheel rotating with the actuator!
If the handwheel is moved while the drive motor is running, there is a risk
of injury such as the upper limbs being drawn in or caught by the rotating
handwheel.
–
Do not operate the handwheel unless the voltage supply has been
switched off.
NOTE
Risk of property damage caused by overrunning the limit switches or
cancelling the adjustment of the potentiometer!
–
In manual operation, take care not to move the valve beyond the end
positions set by the limit switches within the actuator.
–
Mechanically limit the valve end position before moving the actuator in
manual operation.
