j) Harvest Completion Detection Control (S2 dip switch 4)
Do not adjust. This must be left in the factory default position or the unit will not operate
properly.
It is deactivated on the KM-40B, KM-55B, and KM-80B.
When activated, this control determines whether ice remains on the evaporator at the
end of a harvest cycle and at the beginning of a freeze cycle. If ice drops and activates
the bin control switch in the last 10 seconds of a harvest cycle, the control determines
that ice still remains on the evaporator and extends the harvest cycle for 30 seconds.
If the bin control switch is activated at the beginning of a freeze cycle, the control
determines that ice still remains on the evaporator and starts a harvest cycle after the
minimum freeze cycle time has passed.
