Restoring Force Adjustment
The force exerted by the restoring spring can be adjusted to cater for a wide range of head and rotor
configurations.
The factors affecting the setting are:
Rotor weight and diameter
If the unit is damped or un-damped. .
General friction within the installation
User preference
The minimum force is always that required to rotate the unit to the next home position after the rotor
has moved half way through the cycle following a release signal. The length of the spring should be
adjusted to achieve this. (Spring length is shortened to increase the force and lengthened to reduce
it).
Carry out checks at various positions in the cycle by ensuring that the unit, when starting from a static
position, will always be fully restored to the home position.
The restoring force may be increased as required to suit user preference.
