OPERATING AND PROGRAMMING INSTRUCTIONS
8-18
In this screen, a pre-defined program can be selected with the numeric buttons 0 to 9 or with
the ARROW UP and the ARROW DOWN buttons. The currently selected program number,
together with the program name is displayed in the lower line of the display. If the arrow buttons
are used in combination with the SHIFT button, the selected program will be increased or decreased
by 10.
When the correct program has been selected, this has to be confirmed by pressing the
ENTER button. When this button is pushed, the selected program will be activated and the
overview screen is displayed again. When this has been done the cycle can be started (go to chapter
5.2).
It is also possible to use the START button. If this button is used, the current selected drying
program will be chosen, the drying program will be started immediately and the main screen is
activated again. This means that cycle start as described in chapter 5.2 is executed immediately. If
no alarms are active, go to chapter 5.3.
5.1.2 Entering a single cycle program
As explained in chapter 5.1, it is also possible to enter a single cycle program. This is used
in special circumstances like partially dried batches and special materials. If the SELECT
PROGRAM button is used in combination with the SHIFT button, the screen for entering a single
cycle is displayed. In the single cycle screen, a self chosen drying time and temperature can be
entered. By default, the values are as defined in program 50 and these values can then be adjusted
by the user.
The screen will start up with the edit-field on the drying time. If necessary change the drying
time value with the PLUS or MINUS buttons or with the NUMERIC buttons and confirm with the
ENTER button. When the ENTER button is pushed, the cursor will move to the drying temperature.
Change the value if necessary in the same way and confirm with the ENTER button. When the
ENTER button is pushed while the cursor is on the drying temperature, the overview screen is
activated again, and the cycle is ready to be activated (see chapter 5.2).
In the screen for entering a single cycle drying time and temperature, the cursor can be
moved to the next or previous edit-field with the ARROW UP and ARROW DOWN buttons.
When a single cycle program is finished, the controller will automatically switch back to the
pre-defined program which was last used before the single cycle was started.
5.2 Starting the cycle
After the correct program has been selected, a program cycle can be started with the START
button. If this button is pushed, the software will check if all inputs are in the correct state. If so, the
cycle is started and step 3 is activated (see chapter 5.3). If one of the inputs is not in the correct
state, the lower line in the display will show an alarm text and the numeric display above the
graphical display will start blinking with the alarm number. A full explanation of the available
alarms and their cause can be found in the chapter 7.
5.3 Program running
In this step the program cycle is running. A program cycle can be a drying step, a cool-down
step or both. When running, the 2
nd
line in the overview screen will show the current status (see
chapter 4).
In case an alarm occurs, the machine will be stopped by the controller and the program cycle
will be paused. The same will happen if the STOP button is pushed.
