Does anyone have information on what is needed to convert a GEA Micro III from a potentiometer for slide valve position to an LPI. Customer replaced a Howden with a pot with a new Howden with LPI. I've seen Micro III with LPIs tied into them before but now that the panel is obsolete it may be difficult to do the conversion.Any help would be appreciated.

Thank you

Check your email with information I have.
GEA should be able to advise you if you buy their LPI (you would think).
If you have 4 -20 Ma should be fine.

You can get converter from Potentiometer/resistive to 4-20mA

Thank you for the replies. The information you sent me was very helpful. Changed two jumper positions.Wired it up and now the compressor is running great with the new LPI.

Thanks for your help

Forgot to mention I had to calibrate due to a Vi adjustment.
