2. CONTROLLER BOARD
[a] SOLID-STATE CONTROL
1)A HOSHIZAKI exclusive solid-state control is employed in KM-1300SAF,
KM-1300SWF, KM-1300SRF, KM-1300SAF3, KM-1300SWF3 and KM-1300SRF3 Stackable Crescent Cubers.
2)A Printed Circuit Board (hereafter called “Controller Board”) includes a stable and high quality control system.
3)All models are pretested and factory-adjusted.
[b] CONTROLLER BOARD
CAUTION
1.Fragile, handle very carefully.
2.A controller board contains integrated circuits, which are susceptible to failure due to static discharge. It is especially important to touch the metal part of the unit when handling or replacing the board.
3.Do not touch the electronic devices on the board or the back of the board to prevent damage to the board.
4.Do not change wiring and connections. Especially, never misconnect
K3, K4 and K5, because the same connector is used for the Thermistor and Float Switch. K4 is not connected.
5.Do not fix the electronic devices or parts on the board in the field. Always replace the whole board assembly when it goes bad.
6.Do not short out power supply to test for voltage.

Features of All Three Controller Boards
(1)Maximum Water Supply Period - 6 minutes
Water Solenoid Valve opening, in the Defrost (Harvest) Cycle, is limited by maximum period of the defrost timer. The Water Valve cannot remain open longer than the maximum period. The Water Valve can close in less than the maximum period if the defrost cycle is completed.
(2)Defrost Timer
The defrost cycle starts when the Float Switch opens and completes the freeze cycle. But the Defrost Timer does not start counting until the Thermistor senses 48°F at the Evaporator outlet. The period from the end of the freeze cycle up to the point of the Thermistor's sensing varies depending on the ambient and water temperatures.
(3)High Temperature Safety - 127 ± 7°F
The temperature of the suction line in the refrigerant circuit is limited by the
High Temperature Safety.
During the defrost cycle the Evaporator temperature rises. The Thermistor senses 48°F and starts the Defrost Timer. After the Defrost Timer counts down to zero, the normal freeze cycle begins. If the Evaporator temperature continues to rise, the Thermistor will sense the rise in temperature and at 127
± 7°F the Thermistor operates the High Temperature Safety.
17
This High Temperature Safety shuts down the circuit and the icemaker automatically stops. To reset the safety, turn the power off and back on again.
This High Temperature Safety protects the unit from excessive temperature.
(4)Low Water Safety
If the Pump Motor is operated without water, the mechanical seal can fail. To prevent this type of failure, the Controller Board checks the position of the Float Switch at the end of the initial one minute water fill cycle and at the end of each defrost cycle.
If the Float Switch is in the up position (electrical circuit closed), the Controller Board changes to the ice making cycle. If the Float Switch is in the down position
(electrical circuit open), the Controller Board changes to a one minute water fill cycle before starting the ice making cycle. This method allows for a Low Water
Safety shut down to protect the Water Pump from mechanical seal failure.
For water-cooled model, if the water is shut off, the unit is protected by the High
Pressure Switch.
(5)High Voltage Cut-out
The maximum allowable supply voltage of this icemaker is limited by the High Voltage Cut-out.
If miswiring causes excessive voltage on the Controller Board, the High Voltage
Cut-out shuts down the circuit in 3 seconds and the icemaker automatically stops.
When the proper supply voltage is resumed, the icemaker automatically starts running again.

Features of Control Products “E” Controller Board
The “E” board includes LED lights and audible alarm safeties. The red LED indicates proper control voltage and will remain on unless a control voltage problem occurs. At startup a 5 second delay occurs while the board conducts an internal timer check. A short beep occurs when the power switch is turned ON or OFF.
The green LED’s 1-4 represent the corresponding relays and energize and sequence 5 seconds from initial startup as follows:

The built in safeties shut down the unit and have alarms as follows:
1 beep every 3 sec. = High Evaporator Temperature >127 ° F.
Check for defrost problem (stuck HGV or relay), hot water entering unit, stuck headmaster, or shorted thermistor.
2 beeps every 3 sec. = Defrost Back Up Timer. Defrost >20 minutes. Orange LED marked 20 MIN energizes.
Check for open thermistor, HGV not opening, TXV leaking by, low charge, or inefficient compressor.
3 beeps every 3 sec. = Freeze Back Up Timer. Freeze > 60 minutes. Yellow LED marked 60 MIN energizes.
Check for F/S stuck closed (up), WV leaking by, HGV leaking by, TXV not feeding properly, low charge, or inefficient compressor.
To manually reset the above safeties, depress white alarm reset button with the power supply ON.
6 beeps every 3 sec. = Low Voltage. Voltage is 92 Vac or less.
7 beeps every 3 sec. = High Voltage. Control voltage > 147Vac ±5%. The red LED will de-energize if voltage protection operates.
The voltage safety automatically resets when voltage is corrected.
The Output Test switch “S3” provides a relay sequence test. With power OFF, place S3 on and switch power to ICE. The correct lighting sequence should be none, 2, 3, 4, 1, & 4, normal sequence every 5 seconds. S3 should remain in the “OFF” position for normal operation.
The application switch located between relay X3 & X4 must be set to match the original board application. Place this switch in the ALP position if there is no white wire supplied to the K1 connector. If there is a white wire, place the switch in the C position. If this switch is placed in the wrong position either the compressor contactor will remain energized with the control switch OFF or the unit will not start.
The dip switches should be adjusted per the adjustment chart published in the Tech Specs book. 7 & 8 must remain in the OFF position.
