Hello everybody,

I've built a box with 5 Led's. Only controllights for beacon, taxi, Nav, landing and strobe lights. It works fine but I will that these lights only run when the battery is on. How can I do that?

Thank you very much!

Hi

Simply include this Condition into the Formulas.

At first create one Output Config that read the Sim Battery Status ... Mostly done with the "Master Battery Switch" . More detailed can be the Master Bus Voltage... Cause extremly the Bat Switch can be ON but the Battery is discharged and also no LED will light.
So lets expect you use Battery switch and we know that Value is 0 for OFF and 1 for ON. Lets call this Output Config now "Bat Status"


Now in each single LED Output Config you like to work with this logic you enable a "Config Reference" (Section below the Variable Entrys)
Choose for a new Line.... Enable the Checkmark ..... Choose for Config "Bat Status" from the List .... And choose for a Placehodler Symbol ..... Lets say "a"

NOW you can use the Value from "Bat Status" by type "a" within a formula.

In Transform you can now e.g. say..... if(a=0,0,$) Means IF Value of "a" (Bat Status) is Zero, THEN show 0 (LED Off) ELSE (So if Bat is 1) show $ (Value from LED in Sim).

More easy is to simply say in Transform : $*a (So we multiply the Value from the LED with the Bat Status.
If Bat is 0 then result is always 0 ...... 1*0=0 ----- 0*0=0 .
If Bat is 1 then result is the LED Status .... 1*1=1 ----- 0*1=0

****************

With same Logic you can also include a Light Test System.
Lets expect Lighttest is also in a Config.... 0 for OFF 1 for Lighttest Running.

Use it as a second Reference and name it "b"

Now we can say Transform ($+b)*a
We still multiply with Battery.... So LED and also Lighttest only work if Batery is ON ( Else always 0)
If Lighttest is ON then b is 1 .... Means we add +1 to the LED Value.
If LED is currently On in Sim then 1+1=2 .... So it still light.
If it would be OFF in Sim then 0+1=1 Means it light now in case of Test Button.

If Lighttest is OFF then we Add +0 means nothing happens.
