LAMP CHANGING

In this chapter only the change of the UviLine Connect 810 / 910 / 930 halogen lamp are explained. Indeed, UviLine
Connect 940 and 960 spectrophotometer works with xenon lamp which time life approaches the one of the
apparatus. Any time, if it prematurely stops working, then contact SECOMAM servicing.
The tungsten halogen lamp is a wear part with a certain average service life. It has to be replaced if defective. The
spectrophotometer has a service hour counter for the lamp module.
NOTE
The replacement lamp is readily assembled as a lamp module and optically adjusted in the factory. Therefore, treat
it with utmost care. Fingerprints on the glass will shorten the service life of the lamp. Do not touch the bulb of the
new lamp module with bare fingers. If you have touched the bulb inadvertently, carefully clean it with a clean cloth
soaked in alcohol.
The halogen lamp is behind a protection cover (Aluminum sheet) at the rear part of the spectrophotometer. To
change it, proceed as follows:
1
WARNING
The lamp becomes very hot during operation. Do not touch the hot lamp because it can cause burns! The
lamp should cool down for approx. 10 minutes before it is exchanged.
9. Switch off the spectrophotometer and disconnect it from the main power.
10. Remove the two screws (1) and remove the lamp protection cover (2).
11. Disconnect the electrical plug connection (3). Disconnecting it might take a lot of effort.
12. Unscrew the two knurled-head screws (4) and remove the defective lamp module (5).
13. Fix the new lamp module with the knurled-head screws. When doing so, the metal-plated side of the PCB
must point outward, toward the knurled-head screws.
14. Reconnect the power supply cable.
15. Reinstall the protection lamp cover.
16. Reset the service hour counter for the lamp module (see
chapter 9.5 of this manual)
