Three wire pressure transducer

[Aleyara]

I need to know if somebody has the diagram of the three wire evaporator pressure transducer for a YT York Chiller, is for troubles
hooting purposes.

Although I don't have the cut-sheet on the exact sensor used in a YT chiller, I have attached a document that covers the wiring of the most common transducer configurations that you would probably run into. I would assume it being a three wire transducer that it produces a voltage signal. You should be able to determine the wiring of yours from the chiller schematic, and then you would know which wire combinations to test for your signal.

Are you getting a message to the effect of "evap pressure tranducer out of range" ?

red is 5vdc supply
black is common
white is signal to panel

if you provide model number and which transducer, I can get more specific

Assuming that you want this info so that you can check the resistance through the transducer, I'll tel you that you can't do that. It's not a potentiometer.

I have seen that error than go away, chiller running fine from what I can tell other than that error. Should I be worried?

The Model is YTL6M6F1-CTF

I've seen that or a very similar message on the one line marquee type display when the machine had air in it. Check your condenser approach and purge rate. Maybe York56 will chime in here.

That particular message is displayed when the evaporator approach is > 25 degrees positive or > 2.5 degrees negative for 10 minutes continuous. Defective ELWT sensor, evap transducer, non-condensables causing a higher saturated refrigerant temp than leaving water temp when there are multiple machines in a plant holding the return water temp down are the 3 most common reasons.

that's an old one will have to go thru the hard copy books for that
which transducer, evap cond oil?
