Machine Errors
70444901 36
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 Back ( ) 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 Back ( ) 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.
Moisture Sensor Error
When in Idle Mode, the control will begin to monitor
the moisture sensor 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 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 “is dryer empty” (display “  ”,
“  ”, “  ” each for two seconds) prompting
the user to answer whether the machine is currently
empty, pressing the Up ( ) or Down ( ) keypads will
toggle between yes and no. If the operator selects “no”
(display “  ”), the control returns to the Idle Mode
display. If the operator selects “yes” (display “  ”)
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 Moisture Sensor
Error (display “  ”), pressing the Back ( )
keypad will clear the error. The “is dryer empty”
prompt will only appear once a day unless machine
power is cycled.
