Camshaft Cycle Positions; Valve Disc Location/Function - Pentair Pro Elite Professional Series Operation Manual

Camshaft Cycle Positions

The front end of the camshaft has an indicator cup. The
cup has slots in the outer edge and cycle numbers on the
inside face (Figure 18).
Remove the cover and look over the top of the Demand
control to view the cycle numbers. The number at the top
indicates the current cycle position of the control valve.
The corresponding slot for the number is positioned at
the optical sensor, which is rotated approximately 90
degrees out of phase.
Note: If electrical power is not available, the camshaft
can be rotated counterclockwise by hand if the motor
is removed.
