Pump-Out/Drain Selector; Harvest Promotion Control; Refill Counter; Harvest Completion Detection Control - Hoshizaki KM-230BAJ Service Manual

7. Pump-Out/Drain Selector (S2 dip switch 1)
The pump-out/drain selector setting determines whether the pump motor energizes
(pump-out) or stays off (drain) after a 2-second delay at the beginning of the pump-out
cycle or at shutdown. Regardless of the pump-out/drain selector setting, the drain valve
energizes after a 2-second delay at the beginning of the pump-out cycle or at shutdown.
When the pump-out/drain selector is set to pump-out, the pump motor takes water from
the tank and forces it through the drain valve and down the drain. When the pump-out/
drain selector is set to drain, water drains by gravity through the drain valve.

10. 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-230BAJ and KM-300BAJ/BWJ.
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.
