8. Extended usage information
8.1 Temperature control (OPTION)
The 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 laser pointer
indicates where the distance check is made. This pointer
is close to being in the centre of the temperature mea-
surement 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, other
optics are available). Make sure to have the measur-
ing 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.
With the temperature 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 alarms (OPTION)
To notice temperature deviations, the dryer is equipped
with a process alarm. If the difference between the
current temperature and the requested temperature is
more than 30ºC (adjustable, see 9.4.28), 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 pro-
gram 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 dryer is delivered.
Please see chapter 9.4.3 for activating.
8.3 External start and stop
There is an input in this SingleHeater Control Unit to
enable a remote start and stop of the drying process.
This function can be integrated in the overhead process.
When the remote start contact is closed, the drying
process will automatically start according to the pre-set
program (1-15). It will then stop when the remote start
contact is open. See electrical drawings chapter 12.
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 9.4.6.
Advanced PIN code
5780
Used for program adjustments and advanced settings. To
change this code, read chapter 9.4.14.
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 editing 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 re-
directed to program mode. You will then need to repeat
from step 9.1 Log In to enter 9.4 Settings again.

arrow keys
to
change language and
select
to confirm.
Use the
arrow keys
to scroll through the
settings, see table in
