6.1.2 Gearbox decoupling
Gearbox decoupling is required to manually moving the output shaft during
the adjustment process.
NOTE
Risk of property damage when the gearbox is decoupled!
The valve must not be twisted when the gearbox is decoupled. Decoupling
cancels the holding torque of the motor, which may cause uncontrolled
movements of the valve and damage the actuator gearbox.
NOTE
Risk of property damage caused by overrunning the limit switches or
canceling the adjustment of the potentiometer!
–
In manual operation, take care not to move the valve beyond the end
positions set in the actuator.
–
Mechanically limit the valve end position before moving the actuator in
manual operation.
–
Do not actuate the actuator electrically when it is decoupled!
Important information!
The end position of the adjusting knob in
the position
= M
ANU
depends on the
stroke required to disengage the gear-
wheel.
Turn the adjusting knob ( A
UTO
/M
ANU
) only
so far until you feel a distinct resistance.
