closed for at least 5 seconds (it is flagged as an airflow switch
bounce). If there are 5 airflow switch bounces within 5 minutes
the control will go to the Cool Down portion of the cycle, display
an error message and sound the audio signal. When the Cool
Down portion of the cycle ends, the control will continue display-
ing the error message until power is cycled or a user presses the
Back keypad.
Rotation Sensor Error
If the machine is equipped with a rotation sensor, the control will
constantly monitor the input and calculate the cylinder’s rpm. If
the rpm drops to zero while the cylinder is supposed to be spin-
ning, the control will go to the Cool Down portion of the cycle.
The control will display an error message and sound the audio
signal. Once the Cool Down portion ends, the control will contin-
ue to display the error message until power is cycled to the ma-
chine.
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 por-
tion of the cycle ends, the control will continue displaying the er-
ror message until power is cycled or the Back keypad is pressed.
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.
DIP Switch/Harness Index Mismatch Er-
ror
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 inva-
lid setup the control will not enter Idle mode and instead enter Er-
ror Mode. The control will ignore all user inputs and display an
error message. The machine must be powered down and the cor-
rect 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 mois-
ture 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 consis-
tent load sensed, the control queues the “is dryer empty” (display
iS
,
drYEr
,
EnPtY
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
no
), the control returns to the Idle Mode
display. If the operator selects “yes” (display
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
Moisture Sensor Error (display
EnoiSt
), pressing the Back key-
pad will clear the error. The “is dryer empty” prompt will only
appear once a day unless machine power is cycled.
