7.2.7 Replacing the fid cable assembly
This procedure requires a special tool, Insertion Tool ABB P/N TL799M013-1, to assist in passing the cable
through the insulation between the Electronic Housing and the Oven.
1. Cut the cable just below where it passes through the Oven into the Electronics Housing and remove the cable from the
Oven.
2. Disconnect the other end of the cable from the FID Amplifier Assembly and remove the cable from the Electronics
Housing.
3. Remove the grommets from the grommet holes (located in the side of the Electronics Housing and the side of the Oven)
that will accommodate the routing of the new cable.
4. The new FID Cable Assembly has a Microdot connector on one and a BNC connector on the other end (see Figure 7.2).
Screw the Microdot connector end of the new cable assembly into the Insertion Tool.

5. Pass the Insertion Tool through the grommet holes from the Electronics Housing to the Oven.
6. Remove the Insertion Tool from the cable connector.
7. Make a slit in each grommet from the outer diameter to the inner hole. (This is necessary because the cable connector will
not pass through the grommet.)
8. Position the cable in the grommets in the Electronics Housing and the Oven.
9. Push the grommets into the grommet holes.
10. Connect the cable connectors to their respective locations (BNC connector to the FID Amplifier Assembly and Microdot
connector to the top of the detector).
