Key Normal state Editing
HOLD
LEARN Interrupt Process
• The <HOLD> key interrupts
the processing of a method.
However connected periph-
eral instruments (Titrinos, etc)
are not halted. Only method
processing is interrupted.
• In the “HOLD" state a method
can be completely halted with
<STOP> or continued with
the next command in line by
pressing <START>.
• After quitting an error mes-
sage during method process-
ing the changer automatically
goes into the <HOLD> state.
Switch on LEARN mode
• The <LEARN> key serves to
start the Learn mode. This
mode is provided for easier
editing of process sequences.
It allows direct acceptance of a
parameter value that has been
set by manual control. LEARN
mode is available for the fol-
lowing commands:
LIFT, DOS, SCN, WAIT
• See page 34 also.
QUIT
Quitting error message
• With the <QUIT> key error
messages can be acknowl-
edged. Before acknowledg-
ing error messages, the cause
should be remedied.
• The command during which
the error message occurs will
nevertheless be carried out
(during manual operation).
• If an error occurs during
method processing the error
message is acknowledged by
pressing the <QUIT> key
and the method is interrupted
(HOLD state). Afterwards
<START> can be used to
continue with the following
command line or <STOP>
will halt processing.
lnterrupt processing of current
command line
• During the processing of a
method <QUIT> stops a run-
ning command and continues
with the next command. This
is useful when a programmed
waiting time is to be shortened
or when the expected signal
cannot be received during a
SCAN command.
Interrupt, select next highest
menu level
• With the <Quit> key the active
(sub)menu or a menu or com-
mand line is exited. The next
highest menu level or the basic
state is selected.
• Any data from a menu or
command line which has been
changed will not be taken over
in this case. This will be sig-
naled by an acoustic signal.
