2.4.3 Settings in the «IC Net 2.1» program
During configuration of the 793 IC Sample Prep Module, the IC Net
assistant “New system wizard” requires the definition of an “Event line”
for the SP Module A. Although this is not installed you must enter any
unused “Event line” to enable the program to proceed. Actually, the SP
Module A is controlled by the 766 sample processor (see Fig. 8).
The signal for switching the internal IC Suppressor Module is not
provided by the 766 program. For this purpose, in the IC Net program
the 733 IC Separation Center parameter “Auto Step” must be set to
“fill”.
The peristaltic pumps of the 752 IC Pump Unit and 793 IC Sample Prep
Module are started when the IC system is activated (measuring
baseline). For this , the option ’Start pump with startup hardware Start pump with startup hardware Start pump with startup hardware Start pump with startup hardware’ has
to be selected for both devices.

Program for the 766 IC Sample Processor:
001 Ctrl INIT 732
002 Move sample
003 Lift work
004 Ctrl ZERO 1
005 Ctrl FILL A 1
006 Pump 120 s
007 Ctrl INJECT A1
008 Ctrl STEP MSM 753
Initialize remote interface
Move needle to sample position
Place lift with needle to working position
Trigger autozero at 732 IC Detector
Switch injection valve A at 733 to "Fill"
Pump sample to sample loop via SP Module A (*)
Switch injection valve A at 733 to "Inject"
Switch SP Module A to next position
(*) The time for pumping the sample to the SP Module A should be as small as
possible to minimize the loading of the cation exchange material.
