8.1

Temperature control

The mobile dryer is equipped with an automatic temper-
ature control. This enables optimum drying/curing results
within the shortest possible time.
The properties when the temperature control is on are:
a
b c
a. minutes
b. temperature increase/minute
c. max allowed temperature
The temperature control (pyrometer) measures the aver-
age temperature over a surface. The diameter of this sur-
face equals half of the distance between the IR cassette
and the object to be dried. The laser pointer indicates
where the distance check is made. This pointer is close
to being in the centre of the temperature measurement
also.
In settings mode, the short and long limit for a "correct"
distance measurement can be adjusted. Default correct
distance is between 55 and 65 cm.
Note! The temperature is measured as an average of the
measured surface (default diameter value 30 cm). Make
sure to have the measuring surface placed correctly.
Make sure that you don´t measure the temperature on
glass, tyres or outside the object. Otherwise, the result
between the programmed temperature values and actual
values may differ. This may lead to unsatisfactory results
and if the process alarm is activated it will stop the dry-
ing/curing.
Consequently, for surfaces smaller than ∅30 cm which
the temperature control cannot read, we recommend
deactivating the temperature control. To permanently
deactivate the temp. control see chapter 9.4.9.
With the temp control deactivated the program properties are:
a b
a) minutes
b) percent power of max possible
The program settings with or without the temperature
control activated are working independently of each
other.
8.2 Process alarm
To notice temperature deviations, the mobile dryer is
equipped with a process alarm. If the difference between
the current temperature and the requested tempera-
ture is more than 30ºC, the message "Warning! Process
error" appears in the display and the dryer switches off
automatically. This warning has to be acknowledged by
pressing enter. By doing this, the program is terminated.
In case of process alarm, check if the temperature mea-
suring device (pyrometer) is aligned correctly on the
surface to be dried and that it is not registering unwanted
material temperatures.
Attention: The process alarm function is not activated
when mobile dryer is delivered.
Please see chapter 9.4.3 for activating.

9. Settings Mode

9.1 Log In
To enter the settings mode you first have to "log in". Press

to confirm and edit the second, third, and fourth digit of
the code.
No code is required for basic settings, just press OK
for the default code of 0000. To change this code, read
chapter "9.4.5 Basic PIN code".
Advanced PIN code
Used for program adjustments and advanced settings.
To change this code, read chapter 9.4.13 "Advanced Pin
Code".
Attention! An entered PIN code is valid globally in the
software until the main switch is turned off, i.e if you enter
advanced settings mode and then exit to program mode.
The program settings will still be editable until the main
power is turned off.
9.3 Navigation
To adjust a setting, press edit. To go back from edit mode
