REX615 Operation Manual

Indication messages and tripping data are shown in a dialog box. Only one dialog box can be shown at a time, therefore the relay has internal priority for indication messages and tripping data. Internal fault and warning messages have always higher priority than start or trip information. Trip information has always higher priority than start information.

  1. Read the indication message in the dialog box.
    The message can indicate the starting or tripping of protection functions or an internal fault in the device.
  2. Press to close the indication message without clearing it or press to activate the Clear view and to clear messages.
