Open/close position detection adjustment
The limit switches or detectors are factory adjusted.
It is not necessary to re--adjust before valve mounting on site.
Nevertheless, if you wish to re--adjust after a maintenance operation, proceed as follows:
-- Remove the cover of the box.
-- Put the disc in extreme position (opening or closing).
-- Unscrew the two metal screws one turn.
-- Adjust triggering of the required detector by turning the coloured screw corresponding to the colour of the cam to adjust.
-- Proceed in the same manner with the opposite switch.
-- Each cam is adjusted independently and the adjustment does not affect in any way the adjustment of the other cam.
-- When adjustments are completed, slightly tighten the two metal screws to prevent adjustments being changed.
-- Replace the cover of the box.
