6. Operation
6.1 Manual 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.
6.1.1 Manual operation: engage
Information When using brake motors, note that the motor is disengaged during manual operation.
For this reason, the brake motor cannot sustain any load during manual operation.
The load must be sustained via the handwheel.
Damage at the change-over mechanism due to faulty operation!
→
Engage manual operation only during motor standstill.
→
Only pivot change-over lever manually.
→
Do NOT use extensions as lever for operation.
1. Pivot change-over lever manually to approx. 85° while slightly turning the
handwheel back and forth until manual operation engages.
2. Release change-over lever (should snap back into initial position by spring ac-
tion, if necessary, push it back manually).
3. Turn handwheel in desired direction.
→
To close the valve, turn handwheel clockwise:
➥
Drive shaft (valve) turns clockwise in direction CLOSE.
6.1.2 Manual operation: disengage
Manual operation is automatically disengaged when motor is started again. The
handwheel does not rotate during motor operation.
