Extended usage information

8.1

Temperature control

The mobile dryer is equipped with an automatic temperature
control. This enables optimum drying/curing results within
the shortest possible time.
The properties when the temperature control is on are:
a. minutes
b. temperature increase/minute
c. max allowed temperature
The temperature control (pyrometer) measures the average
temperature over a surface. The diameter of this surface
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 dif-
fer. This may lead to unsatisfactory results and if the process
alarm is activated it will stop the drying/curing.
Consequently, for surfaces smaller than ∅30 cm which the
temperature control cannot read, we recommend deactivat-
ing the temperature control. To permanently deactivate the
temp. control see chapter 9.4.9.
With the temp control deactivated
the program properties are:
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 temperature is
more than 30 ºC, the message "Warning! Process error" ap-
pears 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 measur-
ing 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.

Log In
To enter the settings mode you first have to "log in". Press
both arrow keys as you turn the main switch on. The
display will ask you for a PIN code.
PIN code
Use the arrow keys to fill in the correct digit. Press enter 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.
Navigation
To adjust a setting, press edit. To go back from edit mode to
settings mode without saving, press cancel.
Note! If you press exit from settings mode you will be
redirected to "program mode". You will then need to repeat
from step "9.1 Log In" to enter "9.4 Settings" again.
Navigation example:
Use the arrow keys to
