2.2.2 732 IC Detector as "Master"
When an IC system consisting of 732 IC Detector, 733 IC Separation
Center, and 709 IC Pump is operated with the 732 IC Detector as
"Master" the 750 Autosampler sample change procedure will be started
by a signal from the 733 IC Separation Center. The Autosampler must
be connected to the 733 IC Separation Center with two cables 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 Auto-
sampler 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
and 6.2140.010 connector plug to contact closure strip 10 10of
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).
