[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
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 flashes.
[f] SHUTDOWN
When BC is activated (BC open), the “POWER OK” LED flashes. There is a delay before the shutdown sequence begins. The delay varies depending on the cycle the icemaker is in at the time of activation. For details, see the table below.
Cycle at Bin Control Activation Delay Before Shutdown Sequence Begins
Fill Cycle | 15 seconds |
Harvest Cycle | 15 seconds after the next freeze cycle starts |
Freeze Cycle | 15 seconds if BC is activated between the beginning of |
| freeze and termination of the |
| timer (timer starts when the thermistor temperature drops to |
| 36°F (2°C) (5.5 kΩ or more)). After this time, the unit will not |
