Controller-Analyzer Wiring

This section applies only to GC systems which have not been shipped "prewired." In most
cases, the purged system will already have had the Controller-Analyzer connections made. If
your system has already been wired, skip this section, and proceed to the next section.
Applicable to the digital and analog I/O lines connecting to the GC Controller, including the
Analyzer-Controller Interconnect lines: Any loop of extra cable left for service purposes inside
the GC Controller purged housing must not be placed near the conduit entry for AC power.
If the above precaution is not followed, the data and control signals to and from the GC
Controller can be adversely affected.
To make wiring connections between the GC Controller and Analyzer, follow these steps:
(1) Disconnect all electrical power to both the Analyzer and the GC Controller.
(2) Ensure that Interconnect Cable wiring connections to the Analyzer have been made as
explained earlier in Section 3.3.1, this manual.
(3) At the GC Controller site, remove the Controller enclosure's front panel.
