Varyscan 3 Special 250MSD
5. Troubleshooting
5.1 Change thermal fuse
WARNING: Contact qualified service personnel!
Warning: Disconnect fixture from mains, and allow
hot lamp to cool down for at least 30 minutes!
Remove the 8 screws holding the top cover of the Varyscan and remove it.
Clean the unit (see chapter 4.1).
Loosen the nut which holds the ignitor and place the ignitor outside the case without
removing the cables. The thermal fuse it located in the cable which runs from ballast
to the fuse.
Unsolder the cable from fuse and remove cable by pulling it backwards. Remove the
silicone fabric hose from the thermal fuse and unsolder it from the cable. Install the
new thermal fuse, but make sure not to overheat it during the process of soldering.
Use a continuity tester to check the continuity and coat the cable and the thermal fuse
again with the fabric hose. The fabric hose is most important, because the thermal
fuse is live.
Reassemble the Varyscan.
Test the fan to ensure it is working. A defective fan is the most common reason for
a defective thermal fuse.
5.2 Change eprom (software)
Warning: Disconnect fixture from mains, and allow
hot lamp to cool down for at least 30 minutes!
Remove the circuit board cover which is located behind the mirror holder, by loosening
the screws. Compare the circuit board with the diagram on page 26 to locate the eprom.
Remove the eprom very carefully from the socket and insert the new eprom. The small
mark on the eprom and the eprom socket indicates the right position of the eprom. Make
sure both marks match. Check the pins contact.
Reassemble the cover of the circuit board and test the Varyscans functions.
