3. Manual operation
Engagement lever locked in motor
operation position: the manual
operation cannot be engaged, and
this excludes unwanted local operations.
To engage manual operation, depress (by 20°-30°) the lever in the direction shown on the
photo. Then let the lever automatically return to its rest position. If no engagement is
obtained, slowly rotate the handwheel and repeat the operation.
Rotate the handwheel to obtain the desired operation (normally clockwise rotation to close
the valve).
A label is foreseen on the handweel with an arrow showing the closing direction (clokwise by
default). In case the closing direction is counterclockwise, the label must be removed and
re-mounted upside down.
Warning: Do not manually operate the actuator with devices other than
the handwheel and the declutch lever. Using cheater bars,
wheel wrenches, pipe wrenches, or other such devices on the
actuator handwheel or declutch lever may cause serious
personal injury and/or damage to the actuator or valve
