Power Supply and LED Startup Sequence Trouble
Hello all,
I have an LS6500 that I'm trying to get up and running. According to stories, the power supply failed. I had a new power supply installed, connected all the leads and here is where things go wrong. The machine has a single S+/S- connector, while my PS has two, labeled V1 and V2. The guy who installed the supply told me just find way to connect both the V1 and 2 connectors to the S+/- lead and I'll be good to go. I have created a connector to do just that, but have also tried just connecting on or the other V to it. Either way, with the connection in place, it won't start. The PS cuts out almost as soon as the switch is flipped.
I though maybe since it's just supposed to make sure the right voltage is applied to the wire, I could get away without it and here is my second issue. Without the S+/- connector on, the machine seems to start up. I don't see anything on the terminal, but the LED startup sequence begins. but it seems to sit at the front end board test, and then reset. It runs through the same sequence as before, somewhere in that sequence, the terminal beeps, and then it sits at the board test again.
Any ideas on what could be wrong and if I can get past this without paying someone to do it for me?
Many thanks in advance!
