Review on Enhanced Performance with Progressive Automations Linear Actuator Stroke Power Transmission and Linear Motion Products by Bob Fasho

I connected both to a 40A dual channel relay expansion module and they worked great at first. One of the units blew a 20A fuse and tripped the circuit breaker, so I isolated the drive, ran a test and noticed that somewhere in the drive the wires were shorting out and heating up every time reverse polarity or normal voltage was applied became. It means broken. So now I'm waiting for the help of the manufacturer, call back there. In the meantime, my solar tracking system has failed. I have no food.
