7.1.2 Lid
To determine the temperature of the heated lid. If 0
°
C is selected, the heated lid remains switched off.
Permitted values 0 to 110
°
C
Entry increments 1
°
C
In addition to the entry for the temperature of the heated lid, it is also possible to determine the behavior of the
lid temperature at the start and at the end of a program:
At the start
NOWAIT
The program is started, independent of the lid temperature.
WAIT
The program is not started until the programmed lid temperature has been attained.
Note
:
To accelerate the start of the program, the lid may be preheated using the "Lid" menu.
At the end
FIX
The lid temperature does not depend on the block temperature. The lid heating is switched off at
the end of the program.
AUTO
The lid temperature depends on the block temperature. If 22
°
C is maintained for longer than
five minutes, the lid heating switches off; this is also applicable in the case of a Hold command at
temperatures < 22
°
C.
The six commands for programming can be called up directly using the allotted number.
7.1.3 T Selection also possible using 1
To enter the temperature and the cycle time as well as the accompanying specific options.
The options are entered by positioning the cursor on the program line number and pressing the key.
The options may be entered for every temperature command.
