Replacing The Als Interface Board - Agilent Technologies 6890 Series Service Manual

Replacing the ALS Interface Board

The G2612A ALS Interface board is required to operate the 7683 Automatic
Liquid Sampler. It can only be installed in a 6890 Plus Gas Chromatograph
with a serial number >20,000. While an ALS Interface Board is installed in
the GC, the GC can use only the 7683 ALS.
WARNING Before proceeding, turn off the main power switch and unplug the power cord.
Caution Make sure you are properly grounded with an ESD strap before continuing.
Follow the procedure below to replace the G2612A ALS Interface board.
1. Remove the GC rear panels and the right side cover.
2. If an MIO card (LAN card) is installed, loosen its two mounting screws
and slide the card out of the instrument as shown below.
