Not too sure it would be a personality issue. Do the doors open at each floor in your scenario? Does this installation have an IP8300 landing system or vanes? Does it sometimes run normal? The 5 volt out put has to be at least 5.15 volts. And Gator is spot on with the PCD tool...gotta have it. With the tool (and instructions on which "display" to look at for inputs/outputs) you can verify the personality jumpers and whether or not the CPU recognizes them for the job configuration.
