Bimetal - Sanyo PDG-DXT10L Service Manual

PDG-DXT10L

7-3 Bimetal

There are two bimetal inside of the projector to detect the lamp temperature rising abnormally.
When the lamp1 temperature reaches near 110˚C or lamp2 temperature reaches near 130˚C,
the bimetal opens to stop the operation of the power supply circuit.
The bimetal will automatically return to normal condition, when the lamp temperature becomes
normal (about lamp1=85˚C, lamp2=105˚C).
