Procedure 10. Installing a G2612A Controller Board (6890 Plus)
The G2612A ALS Interface board must be present in a 6890 Plus GC to operate
the 7683B Automatic Liquid Sampler. The GC must have a serial number
greater than 20,000.
Follow this procedure to install the G2612A ALS Interface board.
1 Remove the GC rear panels and the right side cover.
2 Hold the board upright and slightly angled as shown in Figure 30.
3 Place the board onto the mounting bracket.
4 Slide it into the bracket until the cutouts in the board are aligned with the
locking tabs in the bracket.
5 Lay the board against the chassis then slide it in until it stops. The locking
tabs should hold the board in place.
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.
CAUTION
Attempting to slide the entire board under the locking tab will damage the board’s
components.
