INSTALLATION AND ADJUSTMENT PROCEDURE


1. Loosen all (2) Allen head set screws (A) on switch housing (B) and remove magnet housing (C). Do not remove magnet, spring, and spacer from magnet housing.
2. Remove end plug (D) from divider valve where proximity switch will be installed. Proximity switch can be installed on any available divider valve section.
3. Screw magnet housing (C) into end of divider valve. Torque to 15 foot pounds max. Be sure 0-ring or metal gasket (F) is in place on magnet housing (C) if required.
4. Slide switch housing (B) all the way onto magnet housing (C). Connect ohmmeter to yellow switch leads. Do not tighten set screws at this time.
5.To properly adjust switch housing (B), divider valve assembly (G) must be cycling so magnet (H) is moving back and forth. This can be achieved with lubrication system functioning or by manually pumping clean oil through divider valve assembly with a hand pump.
6. If a cycle is not detected, adjustment is made by sliding switch housing (B) out in 1/16" increments. Continuity meter connected to yellow wires will indicate a switch closure. Adjust 1/16" out until correct adjustment is confirmed.
7. Use 10 to 12 inches of flexible conduit on the switch housing for ease of adjustment or maintenance. All conduit and connections should be appropriate for area classification. CAUTION: Conduit and fittings must be supported to avoid bending magnet assembly.
