The monitor and the controller are the main components of the electronic control system. The monitor and the controller have a self-diagnostic function. The first components of the electrical system that should be checked are listed: monitor, controller and communication lines.The action alarm indicators, that are on the monitor panel, alert an operator to a problem in the electronic system. The service program of the controller "Service Mode" can also be used to identify the problems. See Testing And Adjusting, "Using Service Mode". The monitoring system will monitor the system for problems. The monitor will display the problems on the character display, if the "Service Mode" is activated during the machine operation. Existing problems and problems that have not been corrected are shown on the character display, if the "Service Mode" is activated during the stopping of the machine. In order to activate the "Service Mode" of the controller, refer to Testing And Adjusting, "Using Service Mode". According to the number of diagnostic codes, machine operation and machine control may not be possible, if the "Service Mode" is being serviced.
