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 12).

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

Cycle Indicators:

0 = Treated Water

1 = Backwash Cycle

2 = Regenerant Draw Cycle

3 = Slow Rinse Cycle

4 = System Pause

5 = Fast Rinse Cycle 1

6= 2nd Backwash

7= 2nd Fast Rinse

8= Regenerant Refill

764 Control Operation

Power Loss Memory Retention

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.
