1, when ignition key is off, 5VSB is off to prevent the motherboard discharge the battery, it consumes
about more than 50 MA current from battery. It can exhaust your battery at few days.
The whole power module consumes only 100UA at this idle mode(FT-PR120-ITPS,
TONO II except )
2, When ignition key is on for the first time, the MCU is wake up, and drive the 5VCB to output.
3, After a Delay time of Auto-Start signal, (ifthe Auto-Start signal out is set (default), andthe jumper
is on at J2-3&J2-4, and J2-7&J2-8 is connectedto motherboard’s power button). a
pulse signal is sent to motherboard, it will signalthe motherboard to power up. The
default time is 10s.
If you do not connected the On/Off signalto motherboard,the signal still been sent.
The PSU is also readyfor power by waitingthe PS_ON signal in ATX connector.
4, When motherboard pull down the PS_ON signal in ATX, the PSU is power up.
5, After power up,the MCU is now monitoring the power low status, and ACC status. If a lower
power set point is reached and lastfor a setting delay time (default 10s), it will send the
On/Off signalto inform motherboard to shutdown. Also, If a ACCOFF is detected,
MCU will counts a setting delay time (default 30s), MCU sendthe On/Off signal to
inform motherboard to shutdown.
(If the ACC OFF and Lower Power occurs but not continues,the count is cleared.)
In both case, ifthe motherboard is not shutdown in time (40second after On/Off signal
is sent), MCU send the signal again, and counts for 50 second, within thistime ,if the
motherboard shutdown the power, the PSU returnto idle state. If not, atthe end ofthis
Forced Shut Down period, aforced shut down signal of longtime OFF signal is sent,
and then PSU is shut off entirely.
6, If a Auto Start signal is sent to motherboard, and then the PSU power up, worked and shutdown, it
will not auto start again unless the ignition key is off for morethan 50 seconds, it isto
avoid the system is power up so frequently.
7, If any false occurs in power up, work or shutdown period, such as short circuit, over voltage and
so on, the power is shut down and latched off. Recovery from latched shutdown is
accomplished by turn the ignitions key off for at least 5 second.
Timing Setting Guide:
By connecting the PSU to a PC with RS232, with software like HyperTerminal, with the
1200, 8, N, 1
Thetiming of PSU can be set as thefollowing command sets:
(All in Hexadecimal value)
E000H:Getthe all setting value:
b0: Set: Auto Start Signal enabled, clear: disable.
Byte 2: A flag byte always be 0x68,
Byte 3: Delaytime of Auto Start signal after ACC ON.
Byte 4: Delaytime of Shut Down signal after ACCOFF.
Byte 5: Delaytime of Auto Start enable again after ACCOFF.
Byte 6: Power Low Detected level, from 0to 40, represent 10Vto 13V.
Byte 7: Delaytime Shut Down signal after Power low level reached.
Byte 8: Reserved.
E001H:Getthe PSU status value.
E002H: Send a PowerON signalto motherboard.
E003H: Send a PowerON signalto motherboard.
E00FH: Recall all setting.
E1xxH: Set the setting byte 1 value.
E2xxH: Set the Delay time of Auto Start signal out after ACC ON.
E3xxH: Set the Delay time of Shut Down signal out after ACC OFF.
E4xxH: Set the Delay time of Auto Start signal out enable again after ACC OFF
E5xxH: Set Power Low Detected level, from 0 to 40, represent 10V to 13V, 0.075V per step.
E6xxH: Set Delay time of Shut Down signal out after Power low level reached.
