[D] Drain Cycle; [E] Normal Harvest Cycle - Hoshizaki KM-61BAH Service Manual

[d] DRAIN CYCLE

LEDs 4, 5, and 6 are on. Comp continues to run, HGV opens, and FMS de-energizes.
PM stops. DV opens for 20 seconds to drain out the water tank. Drain cycle always
occurs on the 2nd harvest after startup. Then, depending on the control board setting,
drain cycle occurs every cycle, or every 2nd, 5th, or 10th cycle (S1 dip switch 5 & 6).

[e] NORMAL HARVEST CYCLE

LEDs 5, 6, and 8 are on. Comp continues to run, HGV remains open and WV opens.
As the evaporator warms, the thermistor reaches 48°F (9°C). The control board then
receives the thermistor's 3.9 kΩ signal and starts the harvest timer. WV is open during
harvest for a maximum of 6 minutes or the length of harvest minus 0, 10, 30, or 50
seconds (adjustable by S1 dip switch 7 & 8), whichever is shorter. LED 8 goes off when
WV closes. PM energizes and runs for the last 0, 10, 30, or 50 seconds of harvest
depending on S1 dip switch 7 & 8 setting. LED 7 comes on when PM energizes. At the
end of harvest, the control board checks the position of F/S and proceeds to the freeze
cycle if it is closed or calls for a 1-minute fi ll if it is open.
The unit continues to cycle through [c], [d], and [e] sequence until the bin control is
activated and shuts the unit down. When the bin control is activated, the "POWER OK"
LED fl ashes.
