Electrical Connections
The Archon uses a grounded, three-pronged receptacle. Make certain the
electrical voltage is a constant source with no severe drops or spikes in the
voltage. If the power source is not certain, install a power conditioner on the
electrical line. Verify the correct fuse value and voltage selection for the line
voltage to be used.
Attach the power cord to the power receptacle on the rear panel. Check the
power switch located next to the receptacle to be certain it is OFF, plug the power
cord into a three-prong grounded outlet.

Electronic I/O Signal Connections
2.7.1 Purge and Trap Sync Cable Connector
The Archon communicates with the purge and trap concentrator and GC via a
cable specific to each make and model purge and trap and GC. Section 8 details
the Archon to purge and trap connections. The cable plugs into the 25-pin D
connector located on the rear of the Archon, labeled Remote IO. The other ends
of the cable attach to the purge and trap and the GC. See Section 8 for
installation instructions.
I/O signals vary; some GCs and purge and traps use normally-close contact
closures of active-high TTL logic; others use normally-open contact closures or
active-low TTL logic. Refer to the operator's manual for each system for signal
information.
The Archon signal input configuration must be established to properly receive the
purge and trap's output signals for Standby, Desorb and Stop. “System Settings”
details the parameter configurations for each of the signals. The factory default
setting for each signal is CLOSED.
2.7.2 Personal Computer Connection
The Remote RS-232 port on the Archon rear panel allows connection to external
computing devices. Specific software and cables are required for these
connections. Contact your sales representative for these products.

Water and Waste Lines Setup
2.8.1 Blank / Wash Bottle Setup
The Archon is supplied with an 80 oz. bottle and lines for the blank, wash, and
dilution water. Remove the bottle from the accessory kit box. The clear line will
attach to the barbed fitting labeled “Helium” and the PEEK line will attach to the
fitting labeled “Water.” See Figure 2-2, The Archon should be supplied with the
same high purity water (free of volatile organic compounds) that is used with the
purge and trap system. Rinse the bottle with purge and trap quality water then fill
it about 2/3 full with DI water. The bottle can be placed either on the bench top or
on the floor behind the Archon.
