5. TROUBLESHOOTING

Description

All error messages from Super Elf X3 are shown on the display of Loom Dialog panel.

Note:

Details to fault analysis and fault repair are possible to find in the Dornier

Documentation "Dialog Panel Ergo Weave" in chapter 4 "Messages"

The Feeder will also give an alarm by means of the signaling LED (see page 4). The LED is
steady ON during the normal operation of the Feeder. It is fast flashing in case of Heavy
Alarms (i.e. the feeder cannot continue to work), or it is slow flashing in case of Warning
Alarms (i.e. the feeder can continue to work, but some maintenance or checking is required)

In case the loom Control panel will display “ Feeder n. … SYSTEM ERROR 4” please
refer to the Automatic photocells calibration described on page 15.
