Whenever I try to set the time (using the Installation Floppy or Offline Diagnostics Floppy), I get an 0572 error code. I assume it's a hardware problem with the board that houses the internal clock. I'm ready to try a board swap--does anyone know which board has the clock? Thanks in advance. Dave Rosenblitt

Dave, The problems you encounter with setting time are more than likely caused by a faulty transformer (T1) on the AC Distribution Panel. This transformer provides 12vac to the Maintenance Panel, which in turn, converts it to a 5volt supply for powering the MP's logic circuitry. The IOP also works in conjunction with the Maintenance Panel to provide the Time-Of-Day Clock. In nine times out of ten, the transformer breaks down over a period of time, thus reducing the 12vac output enough to cause this failure mode. Replacing T1 with a new Dale IPL-2329-25 transformer should solve your problem. Good Luck, Tom
