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.

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.
