Local operation

For purposes of setting and commissioning, in case of motor failure or power failure,
the actuator may be operated manually. Manual operation is engaged by an internal
change-over mechanism.
Damage at the motor coupling due to faulty operation!
Engage manual operation only during motor standstill.
1. Press push button.
2. Turn handwheel in desired direction.
To close the valve, turn handwheel clockwise:
Drive shaft (valve) turns clockwise in direction CLOSE.
To protect the valve, an overload protection is available as option for manual opera-
tion. If the torque applied at the handwheel exceeds a certain value (refer to order-
related technical data sheet), the shear pins will rupture and the handwheel can no
longer transmit the torque (= handwheel is spinning). Motor operation is still possible.
Manual operation is automatically disengaged when motor is started again. The
handwheel does not rotate during motor operation.
The local operation of the actuator is performed using the push buttons of the local
controls.
