Machine Errors

The control displays and logs errors as they occur. When the control senses the error condition, the audit counter for that error increases by one. The control saves the time and date of the last eight (8) errors that have occurred. Following is a list of possible errors:

PDA Communications Error

These errors may occur during communications. When an error occurs, the display indicates the error message on the control for a few seconds. When a PDA communication error occurs, the audit counter Total Bad IR Communications is incremented, the hour, date, and year of the event are saved, and the error code is saved. An active machine cycle is not affected when there is an error during PDA communications and this error information is not stored in the Last Eight Alarms Menu.

Network Communications Error

Network errors may occur during communication with a network. When a network communication error occurs, the audit counter Total Bad Network Communications is incremented, the hour, date, month, and year of the event are saved, and the error code is saved. This error is not saved in the Last Eight Alarms Menu and has no affect on an active machine cycle.

Open Thermistor Error

Any time the control senses a temperature less than 0 °F after the first three minutes of an active cycle, the control will go to Cool Down, display this error message, and then turn on the audio signal. The control will continue to display the error message until any of the keypads are pressed, the Cool Down portion of the cycle has ended, and the temperature reading is greater than 0°F. Press any keypad to stop audio signal. Once all three occur, the control will return to the Idle Mode. This error will cause the corresponding Open Thermistor Audit Counter to be incremented and is saved in the Last Eight Alarms Menu.

Shorted Thermistor Error

Any time the control senses a temperature greater than 210 + 4 °F during an active cycle, the control will enter the Cool Down portion of the cycle, display this error message, and turn on the audio signal. The control will continue to display the error message until any of the keypads are pressed, the Cool Down portion of the cycle has ended, and the temperature reading is less than 210 °F. Press any keypad to stop audio signal. Once all three occur, the control will return to the Idle Mode. This error will cause the corresponding Shorted Thermistor Error Audit Counter to be incremented and is saved in the Last Eight Alarms Menu.

Stove and Cabinet Limit Errors

There are up to two Stove Limit thermostats and one Cabinet Limit thermostat on the machine. While the heat relay is on, if the stove temperature or cabinet temperature reaches the high temperature for the particular limit thermostat, the heater will turn off automatically and the control will continue the cycle with no heat until the limit thermostat resets. Once the control reaches the End of Cycle the control will display the appropriate error message, if programmed to do so, and sound the audio signal. The control will continue displaying the error message until the control returns to Idle mode.

The control will increment the appropriate stove or cabinet error counter and record the error in the Last Eight Alarms Menu.

NOTE: On some models the stove and cabinet limit thermostats need to be manually reset. The remainder of the cycle will be run with no heat. On these models, the thermostat(s) must be reset prior to cycling power or the control will return back to Error Mode.
