750 Autosampler as "Master"
When an IC system consisting of 732 IC Detector, 733 IC Separation
Center, and 709 IC Pump is operated with the 750 Autosampler as
"Master" the command to start the next injection after the analysis time
"
Run Time
" has elapsed will be given by the Autosampler itself. In this
case the 750 Autosampler is connected to the 733 IC Separation Cen-
ter with the 6.2128.100 cable as shown in Fig. 6. In addition the 709 IC
Pump can be connected to the 750 Autosampler in such a way that
when the pump stops the Autosampler will also be automatically
stopped (important for unattended continuous operation).
1 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.
The four cable ends are appropriately inscribed with "LOAD
NO" (green), "LOAD COM" (yellow), "INJECT NO" (brown) and
"INJECT COM" (white).
•
Connect the other end of the 6.2128.100 cable to the con-
nections "Ground", "Fill" and "Inject" on the terminal block 38
38
(valve A) or 46
46 (valve B) of the 733 IC Separation Center. The
three cable ends are appropriately inscribed with "GND"
(white), "FILL" (green) and "INJECT" (brown).
2 Electrical connection 750 – 709 (optional)
•
Connect 6.2140.010 connector plug to contact closure strip
10
10 of the 750 Autosampler.
•
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.
