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.

Remove the cover and look over the top of the 764 control

to view the cycle numbers. The number in the opening,

(Figure 20) 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.

Cycle Indicators:

0 = Treated Water

1 = Backwash Cycle

2 = Regenerant Draw Cycle

3 = Slow Rinse Cycle

Cycle

The 764 control features battery-free Time of Day and Day

of Week retention during loss of power. A super capacitor

is designed to keep time for 8 to 24 hours depending on

the installation. If the super capacitor is exhausted the

Logix control will display four dashes

(- - :- -) immediately upon power up. The Time of Day and

Day of Week must be reset.

All other programmed parameters are stored in the static

memory and are retained.
