Hoshizaki DKM-500BAH Pump-Out Frequency Control dip switch 5, Freeze Timer dip switch 9

e)Pump-Out Frequency Control (dip switch 5 & 6)

The pump motor drains the water tank at the frequency set by the pump-out frequency control.

The pump-out frequency control is factory-adjusted to drain the water tank every 10 cycles, and no adjustment is required. However, where water quality is bad and the icemaker needs a pump drain more often, the pump-out frequency can be adjusted as shown in the table below.

f) Freeze Timer (dip switch 9 & 10)

CAUTION

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 freeze timer, machine initiates the harvest cycle. After 2 consecutive timer terminations, machine will shut down, possibly indicating a problem.

The freeze timer is factory adjusted and no adjustment is required.

g) Bin Control

CAUTION

Dip Switch No. 7 must be set to the ON position. If No. 7 is set to the OFF position, the machine will run continuously, causing a freeze-up condition.

This machine uses a lever-actuated proximity switch (mechanical bin control) to control the ice level in the storage bin. No adjustment is required. The bin control is factory- adjusted.

(1) Explanation of Operation

A resistor wire harness connects the bin control to the K4 connector on the control board. When the bin control is calling for ice (proximity switch closed), a 7.9 KΩ reading is sent to the control board to continue operation. When the bin control is activated in the bin full position (proximity switch open), a 15.8 KΩ signal is sent to the control board to
