Hi folks,
Just wanted to share a little diy project as I couldn't find any info on it yet.
I wanted to put an one optical level sensor and 3 float switches on my profilux 4 for ato and awc but I didn't wanted to buy all new sensors while I all had them laying around here..
So after I couldn't find any info on diy connecting an optical level sensor to a p4 i have meshured all the ports on the p4 and this is wath I came up with (see photo)
This only works with an optical sensor that is suited for 12v DC.
Float switch is just a hard on/off contact.
You must measure the ps/2 cable your selve as the wiring colors are not universal the same.
With the cable i used the wire colors are:
Level 1: gl 12v+ gr com - or switch contact
Level 2: rd 12v+ br com - zw switch
IMPORTANT!
It is ofcouse your own risk when you do this and be sure not to short whire any wires when connected to the p4.
WHEN YOU DAMAGE THE P4 WARANTY IS GONE!
