[. . . ] CME256, 506, 656, 806: AutoIQTM Cubers Introduction: This product manual contains the information needed for the setup, installation, initial start up, sanitation and maintenance of this ice machine. All series of these 4 models are covered in this manual: Be certain that the information applies to the model in question. If no model is listed, the information applies to all models, including A through F series. This manual is organized in the same way as the expected use of the machine, it begins with specifications, goes thru unpacking and setup, shows where everything is; continues with initial start up, then describes how it works. [. . . ] If the water level does not fall, the machine Shuts Down on a Water Error. January 2002 Page 16 CME256, 506, 656, 806: AutoIQTM Cubers Technicians Only: Harvest Cycle Operational Sequence Harvest The (air cooled model) fan is off. Stacked Units: If the bottom unit is in harvest and receives a The water valve opens and fills the reservoir to the signal from the top unit that it is also in Harvest, the bottom unit will stay in harvest for its Maximum Full level. The water pump shuts off, it will restart in less than Diagnostic Lights and Manual Resets a minute. The controller will shut the machine off if a Note: Machines built after August 1996: malfunction is sensed. Controllers up to 17-1 will · If the machine remains in the harvest cycle shut the machine off after the first malfunction. Controllers marked 17-1 and up will restart the for longer than between 6 to 9 minutes machine 2 times, with a 50 minute interval (depending upon the regular harvest cycle's between restarts. length) the water pump will be switched off If a malfunction is still present after the second until the next freeze cycle. restart, the machine will then shut off and must be · When the bin is full and the unit is in a harvest cycle, the pump will be switched off. During the restart interval, the machine will be off and a diagnostic code The Controller checks how long it takes to fill the indicated. reservoir and if it was too much time, the machine An exception to this is lack of water. switched off because of lack of water, the machine Note: The machine will automatically attempt to will always try to re-fill the reservoir every 20 restart after shutting down because of a lack of minutes. The time between restarts is about 20 Another exception is a harvest error. there must be two consecutive harvest errors to The inlet water valve will stay on and open for a trigger a machine shut-down. With this change, the predetermined fraction of the time it took to fill the controller will still shut down and restart the reservoir. This overflows and rinses the reservoir machine after two consecutive harvest errors. However, if the errors repeat two more consecutive times, the controller will shut down During the Harvest Cycle, ice will be falling from and restart the machine again. If the machine the evaporators and between the bin control's registers two more consecutive harvest errors, the electric eyes. The Controller monitors the ice machine will again shut down and must be falling and stays in the Harvest Cycle until ice quits manually reset. Production of units with Controllers 17-1 began The maximum harvest time is 10 minutes. Higher numbers may Harvest after a restart will be a long one to establish a base line, then the actual time it took to be expected after that date. release the ice is used to determine the length of the next harvest cycle. If no cubes fall (or are sensed) by the end of Maximum Harvest Time, the machine senses a refrigeration error. [. . . ] Trace the sensor wires back to the controller, they are plugged into #5 with the water temperature sensor, and must be replaced with it. Discharge Temperature Sensor Transformer and Compressor Starting Components Single phase compressors use a start relay, start capacitor and run capacitor. All are located in a sheet metal box to the right of the system controller. Remove 2 screws at the front edge of the metal box, and pull the cover forward and out. [. . . ]
