Sensitivity Adjustment
Under the end of the electrical housing on the F60 is a red hexagonal dust cap. If
you remove this dust cap you gain access to an adjustment screw that allows the
paddle preload to be reduced. As supplied the sensitivity adjustment screw is
wound fully in.
In this position the paddle is at its least sensitive. In this position it takes a
substantial force from the moving water to move the paddle. If you wind the
sensitivity adjustment screw anti-clockwise (outward) the force against the paddle
that resists flow will be reduced.
The paddle will become increasingly more sensitive and will respond to
progressively lower and lower flows the further out you wind the adjusting screw.
The total adjustment range is 10 turns of the screw. If you wind the adjustment
screw out beyond 10 turns there will not be enough residual force to return the
paddle to the off position when flow stops.
The range of sensitivity adjustment will also be affected by the orientation of the
controller. In horizontal pipework with the F60 mounted vertically the useable
range of adjustment is approximately 8 turns. In vertical pipe with the F60 installed
horizontally the full 10 turn range can be utilised.
