on the lower display. If the machine is running, the lower line is used to display temperatures and
time left to finish cycle.
Before starting the machine, the overview screen may look like:
1 : Program name
Ready to start
The screen indicates that program number 1 is selected and that the machine is ready to start. If
the S
TART key is pressed, the software will check if all inputs are in the right state. If all inputs are
ok, the cycle is started and the message R EADY TO S TART will be replaced by the current status of
the drying program. The machine will start a drying cycle. If a cycle is running, the lower line can
display 2 different lines:
24 / 75 o C Drying
or
30m + 40m
Which line is displayed depends on the setting in machine parameter 7 (see Section 4.5.3 on page
26). This parameter is used to adjust whether the status line should only indicate the temperature,
only the times, or if the status line should toggle between temperature and time.
3.2.1 Status Line with Temperature
As explained above, the status line with temperature may look like:
24 / 75 o C Drying
The symbol means that heating is active. The machine is warming up to reach or maintain the
programmed temperature. If the software temperature controller decides that heating should be
off, the + symbol will disappear and the symbol will be replaced by a symbol, indicating that
the heater output is off. If the heater output is on, the yellow LED at the upper left of the control
will also be on (see Section 3.2.5 on page 15).
The 24 / 75 o C string indicates the current temperature and goal temperature. In this example, the
current temperature is 24 o C and the goal temperature is 75 o C. In this example the temperature
is displayed in degrees Celsius. It is also possible to use Fahrenheit units. This is adjustable with
machine parameter 1 (see Section 4.5.3 on page 26).
The last text in the line indicates which step in the drying cycle is active. In this example, the
drying step is active. When the drying step is completed the dryer will switch to cool-down mode,
and the text D
RYING will be replaced by C OOLING DOWN .
If the machine is operating with automatic drying with a double temperature sensor, an infra-red
