Infrared Sensor Shutdown Delay - Hoshizaki F-801MAJ Instruction Manual

2. 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) Standard Ice Storage Bin:
When installed on a standard 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, and 3 to obtain the shutdown
delay needed. See the table below. For further details, contact Hoshizaki Technical
Support at 1-800-233-1940.
Note: When the shutdown sequence begins, the compressor de-energizes immediately
and then 5 minutes later the gear motor and fan motor de-energize.
Increasing the shutdown delay allows a higher level of ice in the dispensing unit/
storage bin before shutdown. This could lead to icemaker movement or ice overflow.
