CYCLE COUNT “C”
NOTE: If collections are done on the dryer while the machines are in a cycle, the cycle count may not yet be
recorded, this count will appear on the next collection report. This happens if the collection occurs before
the end of the cycle on the dryer. Also, it must be noted that the method used for the cycle count is similar to
today's electro-mechanical counter and variances may occur due to the windows that exist. If the dryer is
unplugged during the last five minutes of the cycle, an extra count will appear. Also, if switch “C” is out of
adjustment, improper cycle counts may appear.

MEASURING CONTINUITY FROM:
WASHER: RED/YELLOW WIRE
