2.7.1 Cycle Counter
At the end of each cycle the LCD screen will briefly display the TOTAL cycle count
for the machine and also the SERVICE count which is the number of cycles since
the machine was last serviced.
The TOTAL cycle display counts every machine cycle and is not resettable (unless
the machine is reprogramed).
The SERVICE count is reset by the engineer when the machine is serviced. The
service count will also trigger a "Service" message on the LCD display once 20,000
cycles have been completed since the last service visit.
