Hey everyone, I have an older Motoman s3 robot with MRC controller. I have installed my input power to it. I get the source power light on the CPS-18 power supply but no power on light? I have checked all Emergency stops and even replaced the power supply when i could find no other issue. I bought this for an industrial maintenance program i teach in a high school. Any other things i should look for? Does the CPU have an input somewhere that it is looking for to switch on the output DC voltage? thanks kevin
