Replacing The Fid Cable Assembly - ABB PGC2000 Operation And Service Manual

10. For temperature programmed units, install and secure the temperature programmed oven covers.
11. Close and secure the isothermal oven door.

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 Control Housing
and the Oven.
1. Disconnect the Microdot connector located on top of the detector (see Figure 8-8).
2. Cut the cable just below where it passes through the Oven into the Control Housing and remove
the cable from the Oven.
3. Disconnect the other end of the cable from the FID Amplifier Assembly and remove the cable
from the Control Housing.
4. Remove the grommets from the grommet holes (located in the bottom of the Control Housing and
the top of the Oven) that will accommodate the routing of the new cable.
5. The new FID Cable Assembly has a Microdot connector on one and and a BNC connector on the
other end (see Figure 8-9). Screw the Microdot connector end of the new cable assembly into
the Insertion Tool.

6. Pass the Insertion Tool through the grommet holes from the Control Housing to the Oven.
7. Remove the Insertion Tool from the cable connector.
8. 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.)
9. Position the cable in the grommets in the Control Housing and the Oven.
10. Push the grommets into the grommet holes.
11. Connect the cable connectors to their respective locations (BNC connector to the FID Amplifier
Assembly and Microdot connector to the top of the detector).
