2 Installation
750 Autosampler
12
• Connect one end of the 6.2115.070 cable (option) to the
connections "EXTERNAL INJECT INPUT" and "GND" on the
connector plug inserted in the contact closure strip 10 10.
• Connect the other end of the 6.2115.070 cable to the con-
nections "Pos. Fill" on the terminal block 38 38 (valve A) or 46 46
(valve B) of the 733 IC Separation Center so that COM and
GND are connected.
2 Electrical connection 750 – 709 (optional)
• Connect jumper P12 to the control interface of the 709 IC
Pump in such a way that the contacts at outputs 3 and 4 will
be closed when the pump has stopped (see chap. 5.2 of the
709 Instructions for Use).
• Use 6.2134.070 cable (option) to connect outputs 3 and 4 of
the control interface on the 709 IC Pump with connection
"REMOTE STOP INPUT" and "GND" on contact closure strip
10 10 of the 750 Autosampler.
Settings with 732 IC Detector as "Master"
The following settings are recommended for operating the IC system
with 732 IC Detector as "Master":
• 750 Autosampler: " Run Time " = 0.0 min
• 732 IC Detector: operation with cycle program with
command " valve A/B = fill " at time
"
0.0 min
".
2.2.3 Connection to 762 with «IC Net»
When a modular IC system consisting of 732 IC Detector, 733 IC
Separation Center, 709 IC Pump, and 762 IC Interface is operated with
the PC software «IC Net» as "Master" the 750 Autosampler sample
change procedure will be started by a signal from the 733 IC Separa-
tion Center. The Autosampler must be connected to the 762 IC Inter-
face using the 6.2134.000 cable and to the 733 IC Separation Center
using the 6.2128.100 as shown in Fig. 7.
1 Electrical connection 750 – 762
• Connect RS232 interface 11 11 at the 750 Autosampler to one of
the RS232 interfaces 14 14 or 18 18 at the 762 IC Interface using
the 6.2134.000 cable.
2 Electrical connection 750 – 733
• Connect 6.2140.020 connector plug to contact closure strip 99
of the 750 Autosampler.
• Connect one end of the 6.2128.100 cable to the connections
"LOAD NO", "LOAD COM", "INJECT NO" and "INJECT COM"
on the connector plug inserted in the contact closure strip 99.
