3. Infrared Sensor Shutdown Delay
This is the delay between the infrared sensor detecting ice and the start of the shutdown
sequence. The infrared sensor shutdown delay is factory-adjusted to 100 seconds and
no adjustment is required for most dispenser unit/ice storage bin applications.
a) Ice Storage Bin
When installed on an ice storage bin, any shutdown delay setting is acceptable.
b) Dispenser Unit
For typical dispenser unit applications, a 100-second shutdown delay is recommended.
However, on some dispenser unit applications, the ice level at shutoff may need to be
adjusted depending on the dispenser agitation or dispense method. Should a different
shutdown delay be desired, adjust S1 dip switch 1, 2, 3 to obtain the shutdown delay
needed. See the table below. For further details, contact Hoshizaki Technical Support at
1-800-233-1940.
WARNING
Increasing the shutdown delay allows a higher level of ice in the dispenser unit/
ice storage bin before shutdown. This could lead to icemaker movement or ice
overow.
