Freeze Timer (S4 Dip Switch 9 & 10); Float Switch Control Selector (S5 Dip Switch 1) - Hoshizaki KM-1301SAJ-E Service Manual

8. Freeze Timer (S4 dip switch 9 & 10)
Adjust to proper specification, or the icemaker 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 or pump-out cycle. After 2 consecutive freeze timer terminations, the control
board shuts down the icemaker. In this case, see "II.H.3. Low Ice Production" for possible
solutions. The freeze timer is factory set and no adjustment is required. Before changing
this setting, contact Hoshizaki Technical Support at 1-800-233-1940 for recommendations.

9. Float Switch Control Selector (S5 dip switch 1)

Do not adjust. This must be left in the factory default position or the icemaker will
not operate correctly. The KM-1301SAJ-E uses a single float switch with no refills.
Float switch selector used in applications where refill is required in the freeze cycle. Refills
set by S5 dip switch 2 and 3. Note: In single float switch with upper float operation only
1 refill allowed.
• Single float switch application:
• With S5 dip switch 1 in the "OFF" position, control board monitors the lower float switch
for refill operation.
• With S5 dip switch 1 in the "ON" position, the control board monitors the upper float
switch for refill operation. In this case no upper float switch exists, therefore the control
board reads an open upper float switch immediately when the freeze cycle starts and
initiates a refill. Since there is no upper float switch to close and terminate the refill, the
refill lasts for a maximum of 1-min. During the 1-min. refill, LED 4 is on.
• Double float switch application: Float switch control selector determines which float switch
(upper or lower) the control board monitors for refill control during the freeze cycle.
