Interrupt Process
•
The
<HOLD>

the processing of a method.
However connected periph-
eral instruments (Titrinos, etc)
are not halted. Only method
processing is interrupted.

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

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.

command line

ning command and continues
with the next command. This

waiting time is to be shortened
or when the expected signal
cannot be received during a
SCAN command.

key the active
(sub)menu or a menu or com-
mand line is exited. The next

in this case. This will be sig-
naled by an acoustic signal.
