Power Failure Detection System; Error Information Table - Sanyo PLC-HP7000L Service Manual

Chassis Description

Power failure detection system

detection of power failure
Projector provides a protection circuit to prevent the secondary failure when the power failure, fans failure or tem-
perature failure occurs on the projector. The power failure detection lines "PF_AV", "PF_AD", etc. are connected to
the main power supplies and fans. When the failure occurs, IC301<SCALER> receives an error information and then
outputs the signal "PFC_SW_EX" from pin 32. The signal "PFC_SW_EX" is supplied to power supply circuit as the
signal "PFC_SW" via IC1875 <Buffer> to control the power supply operation.
