14. Resetting limit-switching:
— Operate valve away from end-position to account for over-run or to the desired switch tripping
point.
— Push thrust bolt I inwards and turn (fig. 19). The bolt remains in this position.
— For CLOSED position turn spindle marked
(Z), (for OPEN position spindle marked,
O) slowly as indicated by arrow (fig. 19). Distinct "clicks" can be felt and heard. Continue
turning the spindle until the cam operates the switch. At this stage, the spindle should not
"click" any more and should not be turned any further.
If inadvertently you override the tripping point, continue turning the spindle slowly in the
same direction till the switch cam goes back to its original position. Repeat setting
instructions as above described.
— Turn thrust bolt I till it snaps back into its original position by spring action.
15. Torque switching (fig. 20)
If the actuator is switched off by torque switch over its travel before reaching an endposition, please check whether the valve stem is damaged or dirt adhering to it. If
necessary, and with the valve maker’s consent, the setting of the tripping torque may
be raised slightly.
16. Setting : Figures on the torque switch operating cam indicate the valves in Nm (1 mkp = 10
Nm. 1 lbsft. = 1.36 Nm).
Loosen screw and turn the cam till the desired torque coincides with the arrow mark, then
fasten lock-screw.
17. Immediately after start-up : Ensure sealing faces at cover and housing are clean. Check
whether O-ring is correctly in position and apply a thin film of non-acid grease. Replace the
cover and fasten with 4 screws (fig. 21).
18. Fasten control cover screws and tighten glands at conduit entries.
