I was changing a switch lamp for the rollers on the second printing unit tonight, now the press will not function. All buttons function properly when pressed. The delivery and feeder pile will not go up or down, the press will not inch or run. The pictogram on the console is showing the pile height limit switch flashing. The error screen has a “T” inside a circle and “F60” flashing below the electrical cabinet. Can someone provide any direction? An electrician will be on site tomorrow morning to help troubleshoot this. Could a faulty switch cause these errors?
