question Low Air Pressure - Zetor 6211

[nevin]

Today without warning, the low air pressure warning light came on. I have checked the cables to the pressure sensor, they are fine, signal cable not damaged or broken. It's getting an earth via wire [2 wire version]

Note : If I disconnect the signal wire from the pin on the pressure sensor, light goes off.
Does this point to sensor itself or any ideas for me.

Thanks

Hello and welcome here Nevin!

First - based on your posts at zetor -forum.de do you have checked the gauge? Simply make a wire betwen signal and ground (-) and look if the gauge goes with ground to maximum and without to null. If so - the gauge is OK.

After that, as I wrote - make a test wire from signal at gauge to the sensor signal pin and look what happens.
