Machine Errors

Moisture Sensor Error

While in Idle Mode and on the Cycle Menu, the control will begin to monitor the moisture sensor input after one minute without user input. If the moisture sensor circuitry detects a load present signal read consistently (every second) for a ten minute period without user input, the control will declare, if programmed to do so, a load sensed. If at any time during this sensing period, user input is detected or the control determines that there is no load present, it resets the load detected counter. After this ten minute period with a consistent load sensed, the control queues the Load Sensed Menu to display. When user interaction is sensed, the display will wake and show the Load Sensed Menu prompting the user to answer whether the machine is currently empty. If the operator selects No, the control returns to the Cycle Menu. If the operator selects Yes, the control will increment the Moisture Sensor Error counter and record the error in the queue of the last eight machine errors and display the Service Moisture Sensor Menu, instructing the operator to service the moisture sensor soon and press

the keypad to return to the Cycle Menu. The Load Sensed prompt will only appear once a day, unless machine power is cycled. If the control is idle, with the Load Sensed Menu queued, and a Service Schedule Reminder is then queued as well, when detecting user interaction, the control will first display the appropriate Service Schedule Menu and then display the Load Sensed Menu after a key has been pressed.

Fan Motor Contactor Error

If the control attempts to turn on the heater relay and the control does not sense that the Fan Motor Contactor is closed, the control will go to the Cool Down portion of the cycle, display an error message and turn on the audio signal. Once the Cool Down portion of the cycle ends, the control will continue displaying the error message until power is cycled or

the keypad is pressed. This error will increment the Fan Motor Contactor Error counter and will be saved in the Last Eight Alarms Menu.

Fan Motor Centrifugal Switch Error

If the control attempts to turn on the fan motor and the fan motor contactor is sensed closed but the Fan Motor Centrifugal Switch fails to close, the control will go into the Cool Down portion of the cycle, display an error message and turn on the audio signal. Once the Cool Down portion of the cycle ends, the control will continue displaying the error message until power is

cycled or the keypad is pressed. This error will increment the Fan Motor Centrifugal Switch error counter and will be saved in the Last Eight Alarms Menu.

DIP Switch/Harness Index Mismatch Error

On power up the control reads the Temperature Index Harness value and compares that with the value of switch 1, switch 2 and switch 3 on the DIP switch configuration. If the result is an invalid setup the control will not enter Idle mode and instead enter Error Mode. The control will ignore all user inputs and display an error message. The machine must be powered down and the correct temperature index harness must be installed and/or the DIP switch configuration must be corrected.
