The best fault trace software on the market has been
developed with this dryer. In this test all the important
input and outputs to and from the computer can be
tested. This test will give the opportunity to a quick and
accurate function verification of the different parts of the
dryer.
This test procedure is only available in English. By
pressing the yes button you enter the first step of the self
test. To exit the self test, press the start/stop button.
Automatic testing includes the following:

seconds. Press enter or next to continue.
Test 5: Ventilator Test/cassette
The ventilator in the cassette now starts. A sound from
the ventilator confirms that it is working. If the dryer is
equipped with two or more cassettes, you will have to
repeat test no. 4 and 5 for the other cassette/s. Press
enter or next to continue.
Test 6: Laser Test
Direct the laser towards the object. Check that a red,
dotted circle is visible on the object. Press enter or next
to continue.
Test 7: Temperature Sensor Test
Direct the temperature sensor towards an object that is
at room temperature. The temperature on the display
should not deviate from room temperature by more than
±3°C or ±5°F. Press enter or next to continue.
Note! Temperature measurement is made as an average
of a surface according to chapter 8.1.
Test 8: Distance Sensor Test
Direct the distance sensor towards the object at a
distance of 0,3 -1 m. Check that the distance shown on
the display matches the manually measured distance. A
deviation of ±3 cm is acceptable. Press enter or next to
continue.
Test 9: Temperature Guards
The computer card has a temperature measuring device
that is seen to the right on the display.
The cassettes are equipped with temperature sensors
and their temperatures are shown at the left part of the
dísplay.
The temperature is shown in ºC or ºF depending on the
settings you have made.
The computer lifetime will be shortened if temperatures
are above 70ºC/158ºF (and 125ºC/257ºF inside the
cassette) during operation. If this happens during drying,
a new window will appear after the completed drying
cycle saying "warning High temp Pc" (or Cassette). This
will also take place if the cassette temperature exceeds
125ºC/257ºF.
If the cassette internal temperature reaches
140ºC/284ºF, the process will shut off giving an alarm.
