E) Bin Control Selector (S4 Dip Switch 7); F) Factory Use (S4 Dip Switch 8); G) Freeze Timer (S4 Dip Switch 9 & 10) - Hoshizaki KM-2500SRH3 Service Manual

e) Bin Control Selector (S4 dip switch 7)

S4 dip switch 7 is the bin control selector.
Do not adjust. This dip switch must be left in the factory default position or this
unit will not operate correctly.
Factory set for proper operation. Do not adjust. When set to the on position on a unit with
a thermostatic bin control, a 5-beep alarm sounds (open circuit) and the unit does not
operate.

f) Factory Use (S4 dip switch 8)

Factory set for proper operation. Do not adjust. This must be left in the factory default
position.
g) Freeze Timer (S4 dip switch 9 & 10)
Adjust to proper specification, or the unit may not operate correctly.
The freeze timer setting determines the maximum allowed freeze time to prevent possible
freeze-up issues. Upon termination of the freeze timer, the control board initiates the
harvest cycle. After 2 consecutive timer terminations, the control board shuts down the
icemaker. In this case, see "IV.F.3. Low Ice Production" for possible solutions. The freeze
timer is factory set, and generally no adjustment is required. Before changing this setting,
contact Hoshizaki Technical Support at 1-800-233-1940 for recommendations.
