Key Normal state Edit mode
STOP
Stop process and peripheral
instruments
x The 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
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 , the end
sequence of the method will not be
executed.
x In the normal state the
key also stops the pump. The
'>manual stop options' for con-
nected peripheral instruments are
also effective in the normal state.
Stop editing
x causes the editing to
abort and the instrument to return
to the normal state. (exception:
Process sequences).
HOLD
LEARN Interrupt Process
x The 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 or continued with the
next command in line by pressing
.
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 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.
