Disk Scrub Rotation Sensor

      A method for sensing the rotation of disks during the scrub
process is being disclosed.  This system is completely passive, and
will send an alarm in the event of a non-rotation condition.

      The disk cleaners have a disk rotating sensing system that
continuously monitor that the disks 1 are rotating in the tanks.  The
four rollers 2 in the scrub carrier are tied together via timing
pulleys and a timing belt 3.  One of the timing pulleys has a flag 4
that passes in front of a sensor 5 as the disks rotate during the
scrub cycle.  The four rollers are driven, by the rotating disks,
which are driven by the rotating scrub assembly (not shown).

      In the event of a disk rotating failure, the machine will sound
an alarm.  A control panel light labeled "disks not rotating in
tanks" will light, and the cleaner will go into an "Auto Stop" mode.
The machine will then be checked as to the reason for the failure.
Since the machine will go to Auto Stop, the process may be restarted
by pressing "Auto Start".
