LVPS COOLING AIR
In Sleep Mode, M/C turns off the +5V LVPS and +24V LVPS Enable
signal to cut off the +5V DC and +24V DC output.
In Sleep Mode, through +3.3V LVPS remains on, +3.3V DC supplied to
either of the PWBs is cut off to part of ESS PWB and all the parts of
MCU PWB (See CH 1.3.)
LVPS Fan starts low-speed rotation at power on and keeps it with M/C
on standby.
LVPS Fan starts high speed rotation at Main Motor On and transits to
low-speed rotation 15sec (adjustable in NVM) after Main Motor Off.
In Sleep Mode, LVPS Fan stops rotating because +24V DC is cut off.
