Replacing the Master Board

5-4 | FlarePro Process Mass Spectrometer
The Master board is found behind the front panel of the electronics unit
to the left of the heat sink (see Figure 5-1). The entire front panel is part of
the Master board and is returned to the factory when a replacement
board is ordered.
Be sure to record the RS-485 and RS-232/RS-485 dipswitch
settings before shipping the board to the factory to facilitate setting
up the new replacement board later. Also, record the outlets to
which your cables are connected on the panel. See Figure 5-2.
To remove the Master board:
1. Remove the I/O board for easier access.
2. Remove the 1/4" screws from the top and bottom of the unit and the
3/16" screw from the left side of the unit (see Figure 5-1). These three
screws secure the board in place.
3. Loosen or remove the screws at the top and bottom of the option plate
to allow easier access to the removal of the Master board.
4. Pull out the front panel and Master board.
To replace the Master board:

place.
3. Secure the board and front panel in place using the 1/4" screws for the

RS-485 and RS-232/RS-485 dipswitch settings. Plug in the cables as
required.
