  • Page 5: Safety Protections

    Safety Protections This projector provides the following safety protections to operate in safety. If the abnormality occurs inside the projec- tor, it will automatically turn off by operating one of the following protection circuits. 1. Fuse The fuse is located inside of the projector. When both of FUSE PART NO.
  • Page 6: Mechanical Switches

    Safety Protections 3. Mechanical switches There are some mechanical switches inside of the projector to detect that the covers, filters or lamps are mounted correctly. When one of following switches detects an error (open), the projector cannot turn on. This projector provides 4 mechanical switches and 4 lamp selection switches as follows; - Lamp1 cover switch (SW902) - Lamp2 cover switch (SW905) - Bottom cover switch (SW904)
  • Page 7: Temp. And Airflow Sensors

    Safety Protections 4. Temp. and airflow sensors The projector provides 2 temperature sensor ICs and an airflow sensor. The temperature sensor ICs monitor internal temperature and external temperature (around the intake duct ) respectively. The airflow sensor monitors intake air- flow through the airfilter to detect the airfilter clogged.
  • Page 8: Air Filter Replacement

    Air filter replacement Air filters prevent dust from accumulating on the surface of the optical elements inside the projector. Should the air filters become clogged with dust particles, it will reduce cooling fans’ effectiveness and may result in internal heat build up and adversely affect the life of the projector.
