I have a couple of questions about the APU off-on-start switch.

What kind of switch should it be? I have a ON-OFF-(ON) switch. Can I use this one? When looking at the XML-files for download there is 3 XML`s:

APU start OFF
APU start ON
APU start START

Does this mean that I use either the OFF or ON XML from what kind of switch I have?

Or does this have to be an ON-ON-(ON) switch?

Hope you guys understand my question here Smile

If I remember right, it's a momentary "ON" for the start portion, "ON" for the on portion and "OFF" for the off position.

That sound logical to me Smile

But why are there an XML-file for the OFF position then? Thats what I cant understand. XML-file for a position that is not interfaced.

Confused

I don't have an overhead setup at the moment. Maby somethat does and is using the xlm file will be able to help. But what you said sounds right too. If the the APU has not be started and left in the run postion then the software must assume that it is off. Sorry I can't help you more till I get to that point my self.

Ivar, you'll find an ON-OFF-(ON) switch at ELFA (brackets means momentary action). Thus, when the actual switch is OFF, the APU is ON. When you turn the switch to ON, you turn the APU OFF.

Said in other words:

To turn off the APU, set the switch to ON
To start the APU, move the switch to (ON) and release.

If no switches are ON for the APU, then it must be ON (here's where it gets hard...).

I don't know whether you'll need the XML file for the ON position with such a switch, but there is many types of switches...

Thats exactly the switch I have Vidar. From ELFA also Smile

And I understand the logic here, just a little bit hang up because there is 3 XML files. But I guess it is because there is a lot of switch-types and I need to use only two of the XML.

This is the logic as I understand it

Switch ON = APU off = XML APU start off
Switch OFF = APU on = No XML needed
SWitch (ON) = APU start = XML APU start start

Or does this function need an ON-ON-(ON) switch for the function to work properly? And use of all three XML-files?

Nobody has wired this yet?

Bingo. you got it Ivar..
Different variations of toggles require different approaches for the xmls..
three pos toggles only need two XMLs as a rule. The SYS software understand that if the toggle is not in one of the two it MUST be in the third..
