To enter, press the Start keypad. The display will show
dAnPEr
to indicate the damper motor is going to run.
The test must run for at least six seconds before it can be exited
and off for six seconds before the test can be run again.
NOTE: This test does not count towards the total ma-
chine run time operation.
To exit Damper Motor Test, press the Back keypad. The control
will return to the testing mode.
Reverse Motor Test
This option shows the reverse motor running.
To start test, control must be in the Testing Mode. Refer to
at the beginning of this section.
To enter, press the Start keypad. The display will show
rnotor
to indicate the reverse motor is going to run.
The test must run for at least six seconds before it can be exited
and off for six seconds before the test can be run again.
NOTE: This test does not count towards the total ma-
chine run time operation
To exit Reverse Motor Test, press the Back keypad. The control
will return to the testing mode.
Rotation Sensor Test
This option shows the RPM of the tumble dryer cylinder.
To start test, control must be in the Testing Mode. Refer to
at the beginning of this section.
To enter, press the Start keypad. The display will show
rPnHHH
.
The display is updated every ten seconds. The test must run for at
least six seconds before it can be exited and off for six seconds
before the test can be run again.
NOTE: This test does not count towards the total ma-
chine run time operation.
To exit Rotation Sensor Test, press the Back keypad. The control
will return to the testing mode.
Moisture Sensor Test (Shorted Test Jumper)
This step is skipped if the control is not configured for Moisture
Sensing. When entering this test, the control will show
rnC 1
while flashing the Start LED one second on/one second off, al-
lowing the user to short the cylinder to the baffle (orange jump-
er). When the Start key is pressed, this test step energizes the Fan
Motor Contactor and Forward Motor Contactor and the control
will show
HH
. The moisture sensor test is 30 seconds. During this
30 second period, the control is continually monitoring the mois-
ture sensor input for the expected short circuit. If an intermittent
signal or high resistance is sensed before the 30 seconds expire,
the test is terminated and the control will show
OPEn
, indicat-
ing that the test has failed. At this time the user has the option to
press the Back keypad to return and run the test again. If the con-
trol ran the whole test reading the expected moisture sensor level
and without an intermittent signal or high resistance,
PASS
will
be shown. If either the loading or lint doors are opened during the
test, the control will reset the test step and allow it to be run
again. When the test is complete and result is displayed, the con-
trol sounds a 5 second audio signal. Press a key to advance to the
next test step. If the Up or Down keypad is pressed while the test
is in progress the control will toggle between displays
HH
,
rnC
HH
and
SnrHHH
. If the display is left on
rnC HH
or
SnrHHH
for
5 seconds the control will revert to showing
rnC 1
.
Moisture Sensor Test (Resistance Test Jumper)
This step is skipped if the control is not configured for Moisture
Sensing. When entering this test, the control will show
rnC 2
while flashing the Start key LED one second on/one second off,
allowing the user to place the 510k Ohm resistor between the cyl-
inder and the baffle (black jumper) which simulates an expected
moisture sensor level. When the Start keypad is pressed, this step
energizes the Fan Motor Contactor and Forward Motor Contactor
and the control will show
HH
. The moisture sensor test is 30 sec-
onds. During this 30 second period, the control is continually
monitoring the moisture sensor input for the expected moisture
sensor level. If an intermittent signal or unexpected resistance is
sensed before the time expires, the test is terminated and the con-
trol will show
OPEn
, indicating that the test has failed. At this
time, the user has the option to press the Back keypad to return
and run the test again. If the control ran the test reading the ex-
pected moisture sensor level and without an inttermittent signal
or unexpected resistance,
PASS
will be shown. If either the load-
ing or lint doors are opened during the test, the control will reset
the test step and allow it to be run again. When the test is com-
plete and result is displayed, the control sounds a 5 second audio
signal. Press a key to advance to the next test step. If the Up or
Down keypad is pressed while the test is in progress the control
will toggle between
HH
,
rnC HH
and
SnrHHH
. If the display is
left on
rnC HH
or
SnrHHH
for 5 seconds the control will revert
to showing
rnC 2
.
Production Test Cycle
To Enter Production Test Cycle
1.
Be certain control is in Idle Mode.
2.
While pressing and holding the Down keypad with one hand,
press the Back keypad with the other hand.
3.
When the control enters the Production Test Cycle, it will first
display
S HH
with the
HH
showing the software version of
the control.
4.
The control will advance through the sequence of test steps
whenever any keypad is pressed, with the exception of the
Keypad Test. Refer to
for all tests in the Production
Test Cycle.
