5.8 Replacing the Tungsten Lamp
1. Stop the Chromeleon instrument controller or server.
2. Press the power button on the front of the Dionex PDA to turn off the power.
3. Turn off the main power switch on the Dionex PDA rear panel.
4. Grasp the detector front cover by the sides and pull straight off to remove.
5. Standard or semi-micro cell : Remove the tubing bracket from the lamp
cover (see Figure 5-1 ).
6. Remove the flow cell inlet tubing from the tubing guide in the lamp cover (see
Figure 5-1 ).
7. Remove the flow cell cover from the inside front panel (see Figure 5-1 ).
8. Move the flow cell tubing out of the way. Remove the four screws holding the
lamp cover in place, and then remove the cover and set it aside.
9. Squeeze the clip on the visible lamp connector and disconnect it from the 4-
pin bulkhead connector on the side wall (see Figure 5-3 ).
10. Use a screwdriver to loosen the tungsten lamp screws, and then pull the
mounting assembly away from the optical bench.
NOTE The screws are captive in the lamp base and do not need
to be removed.
11. Inspect the new tungsten lamp (P/N 056123T) for fingerprints and dust. If
necessary, clean the lamp with IPA (isopropyl alcohol).
The lamp housing and base may be hot to the touch, especially after
the lamp has been in operation for a long time. Wait until the lamp has
cooled down before continuing.
La lampe et la base de la lampe peuvent être chaudes au toucher,
particulièrement après que la lampe a été allumée pendant longtemps.
Attendez que la lampe ait refroidi avant de continuer.
Das Lampengehäuse und die Lampenbefestigung können sehr heiß
werden, besonders wenn die Lampe längere Zeit in Betrieb war.
Warten Sie, bis die Lampe abgekühlt ist, bevor Sie diese berühren.
