MANUAL 2/4
1.4 Input keys
NEXT
When this key is actuated we
move on to the next pro-
gramming step.
BACK
Similar function to the NEXT
key to move back one step in
the programming tree structure.
OK
This key is used to confirm an
input, to access a main group
of the programming tree struc-
ture or certain program steps to
start a procedure.
END
Actuation of the END key exits from the current step. The program
indicator moves one main group higher.
ALT
This key is used to display the old value again if a wrong input has
been made and the OK key has not been actuated. It also has various
functions in connexion with the definition of the waiters' keys and
clearing the counter tables.
.
The dot key is used to input numerical values with decimal places,
when product names are to be selected from a table (program para-
meters) and when the counter readout are to be printed out on a
report printer.
Input of digit
Enter a digit by means of the key board including the decimal point.
If the input is correct, confirm with the OK key.
If the input is incorrect, the BACK key can be used to move back one
place or the ALT key to recall the previous display content.
An input must therefore be terminated either by OK or by ALT before
we can move on further in the tree.
