Key Normal state Edit mode
STOP
Stop process and peripheral
instruments
x
The <STOP> key terminates a
method.
x
Any peripheral instruments that are
connected (e.g. 709 IC Pump) are
not automatically stopped. In
'>manual stop options'
, a sub-
menu of the Parameter menu, you
can specify what signal or data is to
be transmitted via the interface
involved (remote or RS232) during
manual activation of the <STOP>
key. The connected instrument can
be halted or if necessary, initialized
(see
section 4.3.2
).
x
During a manual halt of a sample
series with <STOP>, the end
sequence of the method will not be
executed.
x
In the normal state the <STOP>
key also stops the pump. The
'>manual stop options'
for con-
nected peripheral instruments are
also effective in the normal state.
Stop editing
x
<STOP> causes the editing to
abort and the instrument to return
to the normal state. (exception:
Process sequences).
HOLD
LEARN
Interrupt Process
x
The <HOLD> key interrupts the
processing of a method. However
connected peripheral instruments
(e.g. 709 IC Pump) are not halted.
Only method processing is inter-
rupted. In the "HOLD" state a
method can be completely halted
with <STOP> or continued with the
next command in line by pressing
<START>.
x
After quitting an error message
during method processing the IC
Filtration Sample Processor auto-
matically goes into the "HOLD"
state.
Switch on LEARN mode
x
The <LEARN> key serves to start
the LEARN mode. This mode is
provided for easier editing of proc-
ess sequences. It allows direct
acceptance of a parameter value
that has been set by manual con-
trol. The LEARN mode is available
for the following commands:
LIFT, PUMP, SCN, WAIT
x
Details concerning the LEARN
mode see
section 4.3.4
