* The quantity of water supplied depends
on DIP switch setting conditions and
water pressure as it is a direct tap water
connection type. (the water supplied is
generally 60 cc to 100 cc)
* DIP switch is on the main PCB.
13-2 Function of Ice Maker
13-2-1 Initial Control Function
1. When power is initially applied or reapplied after power cut, it detects level of ice maker cube mould after completion of
MICOM initialization. The detecting lever moves up and down.
2. Theleveloficemakercubemouldisjudgedbyoutputsignal,highandlowsignal,ofHallIC.Makethecubemouldtobe
horizontalbyrotatingiceejectionmotorinnormalorreversedirection.
3. If there is no change in signals one minute after the geared motor starts to operate, it stops icemaker operation and
check the signal every hour. It resets initialization of icemaker when it becomes normal.
4. Itjudgesthattheinitialcontroliscompletedwhenitjudgestheicemakercubemouldishorizontal.
5. Iceejectionconductsfor1cycleirrespectoficeintheicebucketwhenpowerisinitiallyapplied.
13-2-2 Water Supply Control Function
<Water Supply Quantity Table>
1. Thisistosupplywaterintotheicemakercubemouldbyoperatingwatervalveinthemachineroomwheniceejection
control is completed and ice maker mould is even.
2. The quantity of water supplied is determined by DIP switch and time.
3. If water supply quantity setting is changed while power is on, water supplies for the amended time. If DIP switch is
changed during water supply, water shall be supplied for the previous setting time. But it will supply for the amended time
from the next supply.
4. When water supply signal is applied to water and ice valves at the same time during water supply, water shall be supplied
to water valve. If water supply signal is applied to ice valve during water supply, water shall be supplied to both water and
ice valves.
13-2-3 Ice Making Control Function
1. Ice making control is carried out from the completion of water supply to the completion of ice making in the cube mould.
Ice making sensor detects the temperature of cube mould and completes ice making. (ice making sensor is fixed below
ice maker cube mould)
2. Ice making control starts after completion of water supply control or initial control.
3. Atfirst,Itisjudgedthaticemakingiscompletedwhenicemakingsensortemperaturereachesat-8°Cafter70minutes
when water is supplied to ice maker cube mould.
4. Finally,Itisjudgedthaticemakingiscompletedwhenicemakersensortemperaturereachesbelow-8°Cafter10
minutes in condition 3.
