Machine Errors
70444801 38
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.
