1 Overview of Errors  Current Errors Open the Controller Error Tab Page on the NS-series PT’s Troubleshooter to check the current error’s event name, event code, level, source, source details, time, details, and attached information 1 to 4. However, for some NX Units, you cannot check the event names, event codes, details, and attached information for current errors.
Page 41 1 Overview of Errors Always confirm safety at the connected equipment before you reset Controller errors for a CJ- series Special Unit. When the Controller error is reset, the Unit where the Controller error with an event level of observation or higher will be restarted. Before you reset all errors, confirm that no Controller errors with an event level of observation or higher have occurred for the CJ-series Special Unit.
