Replacing the
TMS control
board
The TMS control board is mounted under a metal cover on the right side of the
TMS (see Figure 3-4).
Carry out the following procedure to replace the control board:
1. Undo the two cover retaining screws and remove the cover.
2. Undo the six screws that secure the board in position.
3. One by one, unplug the connectors and plug them onto the corresponding
connectors on the new board. Remove the old board once all the
connectors have been removed.
4. Mount the new board and secure in position using the six screws.
5. Refit the metal cover and tighten the cover retaining screws.
The procedure for replacing the TMS control board is now complete.
Replacing the
TMS gasket
The TMS gasket is designed to last the lifetime of the equipment. However,
should it become damaged, it can easily be replaced as follows:
1. Strip off the old gasket from the flange.
2. Clean all traces of adhesive from the flange using a suitable solvent.
3. Carefully fit the new gasket onto the flange.
The procedure for replacing the gasket is now complete.
