  • Page 6: Product Overview

    Flow control screw for soft-start function Proximity switch S1 Function The product changes from the normal position to the switching position when both coils are energised simultaneously. The normal position is achieved by switching off both coils. Festo — MS6-SV-...-D-10V24 — 2022-06c...
  • Page 7 In the normal position (completely exhausted product), the pilot valves V1 and V2 are not actuated. If both pilot valves are actuated, the product switches first to the switching position 1 and then, when the switch-through pressure is reached, automatically into switching position 2 è Fig. 2.
