6 Warning and error messages
The pro CONTROL BASIC controllers provide information about the current status via status
and 7-segment display. Warnings and alarms are shown as abbreviations in the 7-segment
display. In addition, the LED band indicates the controller status in green, yellow and red. In
the standard state, the LED band lights up green. An existing warning is displayed in yellow.
Warning messages alert the plant operator to possible problems. However, production
operation is continued. A suddenly occurring alarm is displayed in red. If it occurs, the plant
operator must intervene. For critical alarms, an error acknowledgement or a device restart
may be necessary. The following subchapters contain a detailed list of all warnings and
alarms.
