Hi All,
I want to know that how many seconds will PV750 take for starting successfully and working normally when we use it in -40C ?

Thanks ;
Peter

First Power-Up ("Cold-Boot"):
The PV750 display takes about 7 seconds to power-up to the splash screen and approximately 9-10 seconds total to be operational from the cold-boot state (not previously powered during the last 3 hours). The PV450 takes slightly less time (6 seconds) to power-up from a cold-boot state. The boot time does not significantly change over temperature.

Re-Power Ignition ("Warm-Boot"):
Once the display has been initially powered within the last 3 hours (i.e. in the "warm-boot" state), re-applying power to the ignition instantly turns-on the LCD backlight and re-activates the CAN and RS-485 ports. The display has not re-booted at all and is running in a CANbus-off state.

PowerView displays continue to operate for 3 hours at a reduced power state (~0.25A draw @ 14V) with the LCD backlight turned-off after which a full power-down occurs (i.e. back to the cold boot state).

The default 3 hour time to shut-down can be triggered earlier using the CCM->Shutdown action called from a state machine or a script.

Cheers,

Bryan

Peter,

It basically boots up in the same amount of time at -40C as it does at room temperature, but the display may take longer to be fully visible because it needs to be heated by our internal heater. I am investigating what our results were for the lcd heater to make the display visible at that temperature. When I have that additional information I will get that too you as well.

Thanks,
