Page 8: Modes Of Normal Operation
1.3 MODES OF NORMAL OPERATION Following are details of the operational modes on the U412 and SU412. NOTE: Preset amounts, times, and temperatures listed below describe actual settings on the IntelliTec™ control. Refer to Table 1-1 on page 6 for details on each setting. - Page 9 The “Standby Mode” maintains product quality during slow times, while minimizing reactivation time. This mode lasts for a preset time (Stb Time). Once this time has been reached without user interruption, the control moves into the “Sleep 1 Mode”. Refer to Figure 1-4 for a graphical representation of the “Standby Mode”. If a spigot is opened or the PUSH TO FREEZE button is pressed, the control will move to “Serve Mode”. Product in the front of the freezing cylinders may or may not be at consistency. The state of the product is dependent on a number of variables but will come to consistency quickly. D. SLEEP 1 MODE After the “Standby Mode” time has expired without user interruption, the control will move into the “Sleep 1 Mode”.

After the time has elapsed, an optional audible alarm will sound if this accessory has been installed. The audible alarm is a reminder for the operator to end the “Clean Mode” when cleaning is completed. If the machine is kept in “Clean Mode” for more than 20 minutes, the auger drive motor stops, and an error code (E4) is displayed on the display panel.

- Page 40 Error Code 11 - Low Temperature The Low Temperature Error (E11) occurs when the temperature of the gas refrigerant at the freezing cylinder sensor falls below -20°F. Although the machine will not shut down, the active freezing cycle will immediately end. This error usually occurs when the machine continues to run in a low mix condition or if the machine runs out of mix. The product towards the front of the freezing cylinder tends to freeze solid.
