VALVE SERVICE

Rev A

Camshaft

The camshaft has several lobes that push open the valve discs as the
camshaft rotates. Rotation is controlled by a drive motor that drives a
gear at the rear of the camshaft. The front end has a cup with markings
and slots.

The outside surface of the cup has an arrow mark. When the arrow is at
top center, the camshaft is in the loading position. 90 degrees clockwise
on the cup an optical sensor is mounted to the top plate. This sensor reads
the slots as they pass through. The largest slot is “Home” and the
remaining slots are positioned to signal the regeneration cycles.
When looking at the end of the camshaft, numbers are visible in the
hollow of the cup. An arrow on the top plate points to the current marking.
The numbers represent regeneration cycles as follows:

C0 =Treated water-normal operation mode
C1 = Backwash
C2 = Regenerant draw (not used in filter mode)
C3 = Slow rinse (not used in filter mode)
C4 = System pause
C5 = Fast rinse cycle 1
C6 = Backwash cycle 2 (not used in filter mode)
C7 = Fast rinse cycle 2 (not used in filter mode)
C8 = Regenerant refill (not used in filter mode)

These numbers are offset rotationally 90 degrees from the matching slot.
The offset enables the service person to view the number at the top of the
cup and determine which slot is at the optical sensor.

WARNING:

The camshaft slots are molded to exact dimensions. Do not

attempt to modify the cam cup slots. Improper regen will occur!

NOTE:

If any part of the camshaft is broken or damaged the camshaft should

be replaced. Do not repair or modify damaged cam lobes, gears or timing cup.
