8.2 Troubleshooting
The MultiControl is a complex system. There are many correlations between all participants in the
system. In such a system, of course, errors can also arise, which can result either from the
conveying processes or from the interaction of the individual components. Not all errors can be
displayed in detail and a correlation between the location and the location of the display is not
always possible. A better fault diagnosis is possible by the PLC.
If troubleshooting is not successful, contact Interroll Support and have the following information at
hand:
• Serial number of the affected MultiControl
• Information about the configuration
• Information on the LED displays
• Information on error codes
