We just finished the wiring on our robot and the PCM status randomly turns from green to red without us touching the robot or the controllers. We are using 3 M5 solenoids.
We have tried 3 different PCM, we tested the power from the PDP and the wasn’t the problem, we tried it with one solenoid at a time and it seemed to work and then it randomly started to do it again, we tried programming and even copied our last years program to see if that was the problem and it wasn’t that.
Any Ideas on what it could be? would be greatly appreciated. Thanks!
I think it says it right there: “Most likely the compressor output was shorted”.
But it’s a sticky fault which means it happened before but not right now (as the now column is 0).
That could be the reason for the red status.
Does the PCM red light occur only while the robot is enabled or the compressor is running?
