I'm 2 years new to the at car wash business. Bought a 6 yr old wash (now 8yrs old) with an original Mark vii GT-300 already installed. Until now I've been able to repair everything myself. The Mark vii randomly faults during the wash cycle, every 20 to 30 washes. Sometimes at the beginning of wash, but more often at end of wash, in random locations on the track, sometimes the fault occurs during motion, other times not moving. When the fault occurs, the plc loses total power for 15 to 20 seconds and then comes back to life and sits on the track where the fault occured. There are no error codes recorded because the plc loses power. Has anyone encountered this before?
Any help is appreciated! I've been hunting this ghost for 2 months now, implementing test circuits, etc, with no progress......
