MAINTENANCE
8.1 ANALYZER
The analyzer used with the FCL needs little routine maintenance.
Clean the analyzer case and front panel by wiping with a clean soft cloth dampened with water ONLY. Do not use
solvents, like alcohol, that might cause a buildup of static charge.
Sensor circuit boards are replaceable.
To replace a board
1. Turn off power to the analyzer.
2. Loosen the four screws holding the front panel in place and let the front panel drop down.
3. Loosen the gland fitting and carefully push the sensor cable up through the fitting as you pull out the circuit
board.
4. Once you have access to the terminal strip, disconnect the sensor.
5. Unplug the sensor board from the main board. See Figure 3-2.
6. Slide the replacement board partially into the board slot. Plug the sensor board into the main board and reattach
the sensor wires.
7. Carefully pull the sensor cable through the gland fitting as you push the sensor board back into the enclosure.
Tighten the table glands.
