12V to Analog In possible?

Hi. Can I give a 12V signal to any Analog Input for Lc or AC activation? Or does it kill the Emu?
Also in Manual says to use 5V+ Out from Emu with a 2.2k resistor to Analog Activation? Or can I use 5V without resistor to Analog?

12v is ok.

It does not work :-/
I used 12V + with a switch to Analog 2,
AC Clutch is on Aux6.
I set up correct in Software but when I click the switch nothing happens. But when I klick the Invert output the AC Turns on.

is voltage varies on this analogue input?

To make this work(if 12V is not a problem), your 12V and 5V source have to have the same ground reference.
>> You could try joining power and sensor ground together.
If it doesn't work either way, you can use a relay, your 12V source switches the relay, and the relay switches 5V to the analog input.

I have seen this problem quite a lot recently, you need to check your other settings
if you DONT have sensors reading evap temp and system pressure then you need to set:
Min evap temp -1
AC pressure 0
do this and it will work
