8. Extended usage information

8.1 Temperature control (Only valid for IR)
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 Ø 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 drying/curing.
Consequently, for surfaces smaller than Ø 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 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 (Only valid for IR)
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" 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 measuring 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 both
arrow keys as you turn the main switch on. The display will ask you for
a PIN code.
9.2 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 5780
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 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.
