Hi,
I've just started getting 'Air Pressure Low' warning when pressing Tool Unclamp or running M6 tool change on a working machine.
Manual tool change functions as expected and I can swap tools. M6 won't run through of course. Air pressure reads normal at 80psi at machine regulator. Pressure switch functions and closes at 40psi. 24v supply okay.
I've tried looping through the pressure switch (in case air pressure drops during tool change) to maintain 24v signal and traced through to X27 input - still get error message. Tool Clamped/Unclamped microswitches and signals traced through to X22, all okay.
What am I missing?
Thanks.
