Replacing the Interconnect Board in the Sievers
1. Purpose:
To replace the interconnect board in a Sievers 500 RL TOC Analyzer.
2. Scope:
This procedure applies to all current Sievers 500 RL Analyzer configurations.
3. Safety:
This procedure requires access to electrical components of the Analyzer. Be sure to follow
ESD safety precautions, as instructed. This procedure should be performed by personnel
skilled in the maintenance of electromechanical instruments.
4. Materials:
•
Interconnect board replacement kit
•
Phillips screwdriver
5. Procedure:
5.1 If the Analyzer is taking measurements, press the Stop Analysis button.
5.2 Insert a USB flash memory drive into the port labeled USB on the side of the Analyzer and back up the
current Analyzer settings (Maintenance → Advanced → USB I/O → Save System). For more
information, see the section called "Saving System Settings" in the Analyzer's
Maintenance Manual
5.3 Remove the USB flash memory drive from the USB port and store it in a safe place.
5.4 Turn off power to the Analyzer. Also shut off the circuit breaker for the Analyzer.
5.5 Disable the flow of water to the Analyzer.
5.6 Open the Analyzer door.
5.7 Put on the ESD strap and attach the alligator clip to a metal component of the Analyzer.
5.8 Remove the system board.
5.8.1 Press down on the silver buttons on each side of the system board to release the locking pins
(see Figure 1).
5.8.2 Immediately in front of the pins are the board ejectors. Using your thumbs, simultaneously push
the ejectors out, toward the board guides. This will cause the board to begin to come forward.
5.8.3 Slide the board out of the guides and then out of the Analyzer.
