3.3 Operation via 690 Ion Chromatograph
The 753 Suppressor Module cannot be remotely operated via the 690
Ion Chromatograph unless the installation has been carried out prop-
erly as described in section 2 (mains connection, connection cable
690 – 753, attaching the pump tubing, connection to the IC system).
When operating the 753 Suppressor Module together with the 690 Ion
Chromatograph the pump on the suppressor module must still be
switched on and off manually. In contrast, the suppressor position can
be automatically changed by the 690 Ion Chromatograph.
