I run a Multicam 3000, not even two years old, and recently I got a MODBUS TIMEOUT error, adjusted the wires connecting to the RIO board, working for the moment. since then I've had to replace two of the solenoid at the top of the spindle area to stop a air leak, followed by continuing errors saying there is Low Air Pressure, I have adjusted the air pressure sensor but to no avail.
I currently have a little red light on the top of the #2 solenoid. I've removed the solenoids to be sure there is not debris visible in or on the air manifold.
Fiddled with more wire connections to be sure they were connected well.
...I'm running out of ideas. Got any?
Thank,
JOE
