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
5 = Fast Rinse Cycle
8 = Regenerant Refill Cycle

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.
