Operation

8.3 

Manual mode

The actuator stem can be moved mechanically or electrically. Travel and direction of action 
can be read off the scale of the travel indicator.

8.3.1 

Mechanical override

Handwheel

Travel indicator

Direction

Actuator stem

Extends

Retracts

Fig. 8-2: 

Mechanical override

Direction of rotation

−  Turn clockwise: the actuator stem extends (see Fig. 8-2).
−  Turn counterclockwise: the actuator stem retracts (see Fig. 8-2).

The positioning of the valve is affected when the handwheel (version with positioner) is oper-
ated while the process is running. As a result, zero point and the position feedback do not 
match the calibrated values. Zero calibration, initialization or a transit time measurement 
must be performed again.
