[d] CONTROLS AND ADJUSTMENTS The Dip Switch is factory-adjusted to the following positions: FOR MODELS WITH MECHANICAL BIN CONTROL: DIP SWITCH NO. KM-630MAH KM-630MWH KM-630MRH 1 2 3 OFF OFF OFF 4 OFF 5 ON 6 ON 7 ON 8 OFF 9 ON 10 OFF OFF OFF OFF OFF OFF OFF OFF OFF ON ON ON ON ON ON OFF OFF OFF ON OFF OFF 5 ON ON ON 6 ON ON ON 7 OFF OFF OFF 8 OFF OFF OFF 9 ON OFF ON 10 OFF OFF OFF FOR MODELS WITH THERMOSTAT : DIP SWITCH NO.
Switch Nos. 9 and 10: Used for adjustment of Freeze Timer. The Freeze Timer determines maximum freeze cycle time. Upon termination of Freeze Timer, machine initiates the harvest cycle. After 2 consecutive timer terminations, machine will shut down, possibly indicating a problem. 1) Defrost Control A thermistor (Semiconductor) is used for a defrost control sensor. The resistance varies depending on the Suction Line temperatures.
2) Defrost Timer No adjustment is required under normal use, as the Defrost Timer is adjusted to the suitable position. However, if necessary when all the ice formed on the Evaporator does not fall into the bin in the harvest cycle, adjust the Defrost Timer to longer setting by adjusting the Dip Switch (No. 1 & 2) on the Controller Board. SETTING Dip Switch Dip Switch No. 1 No.
SETTING Dip Switch Dip Switch No. 5 No. 6 OFF ON OFF ON FREQUENCY OFF OFF ON ON every cycle every 2 cycles every 5 cycles every 10 cycles 5) Freeze Timer CAUTION Adjust to proper specification, or the unit may not operate correctly. Two new dip switches numbered 9 and 10 have been added to the improved “E” board to better prevent possible freeze ups. These settings come factory set to the default setting of 60 min. (OFF, OFF). Check the adjustment chart published in the Tech Specs for proper settings.
MODELS WITH MECHANICAL 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. No adjustment is required. The Bin Control is factory-adjusted. [e] CHECKING THE CONTROLLER BOARD 1) Visually check the sequence with the icemaker operating. 2) Visually check the Controller Board by using the following procedures. (i) Adjust the Defrost Timer to minimum position.
3) Check the Controller Board by using test program of the Controller Board. 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, and 4, normal sequence every 5 seconds. S3 should remain in the “OFF” position for normal operation. 3.
[c] TROUBLESHOOTING (MECHANICAL BIN CONTROL ONLY) 1) Machine will not start (i) Move dip switch No. 7 to the “OFF” position. If the machine starts up within a few seconds, the bin control is the likely problem. If the machine does not start up, refer to Section “IV. Service Diagnosis” to verify that non-bin control related issues are resolved. (ii) Check to make sure shipping tape has been removed and the wires are connected properly.
