QT10 Mazatrol T-Plus
Started with "10 overheat" but machine had not even been running. In fact shop is cold.
Replaced QX539 - No joy.
Fiddled around (fans, reset NC boards, remove plugs from QX587 and QX521 one at a time) and now have error code "350 operating switch fault"
Have a QX141 waiting to install but we are hesitent at this point to tear into the QX141.
Have 24v at NC power board. Drives show general E stop condition.
