Mains connectionChrono-X3 4warning!Turn off the main switch before any work is carried out on the electrical circuit.NOTECondensation can form on the weft feeder when it is moved from the cold environment of the warehouseto the warmer environment of the loom room. Make sure that the feeder is dry before switching it on.Take the Voltage Supply Box out of the packing. Openthe cover and connect the three-phase power cord.(4-wires cable). Make sure that the earthconnection is properly made The section of each wirecannot be less than 1,5 mm 2 .Min 4x1,5 mm 2The power supply to the feeder must not bedisrupted when the weaving machine stops.Mains supplyMain switchEmergency stopVariations in main voltage.Ref.

Manual threadingChrono-X3 15WITHOUT CAT• Switch off the feeder.• Align the winding disc eyelet (1).• Open the brush holder (see page 17).• Thread the needle all the way through thefeeder and output eyelet.• Pull the yarn through.• Restart the feeder.1WITH CAT• Switch off the feeder.• Align the winding disc eyelet.• Thread the needle through the feeder andballoon control brush.• Start the feeder and fill the yarn store.• Insert the threading needle into the CAT (2) as faras possible.• Pulling the yarn (3) will cause it to wrap around thethreading needle.• When the threading needle is pulled out (4) the yarnwill follow.32WARNINGWhen using a threading needle, care must be takento avoid damaging the Flex Brake. Ensure thatthe flex holder is in the forward position beforethreading.4Ref. No. 24-893J-2001-02/1232

TEC TensionerChrono-X3 16THREADING THE TEC• Open the cover (1)• Insert a threading needle (2)• Pull on the yarn (3).

Sensor adjustmentChrono-X3 20Opto sensorCertain yarn types may stick to, or leavedeposits on, the sensor mirror.In such cases the clearance between theyarn and the mirror can be increased.Adjust the clearance by rotating the mirror180 degrees.Normal PositionIncreased clearanceCertain yarns may cause excessive vibrationof the sensors. This can be remediedby increasing the damper pressure.Mech. sensorYarn break sensorYarn store sensors+ –+ –Ref. No. 24-893J-2001-02/1232

MaintenanceChrono-X3 21CleaningIt is recommended to carry out a periodicalcleaning of any lint or dust accumulation onthe feeder or the control box.min 20 cmlubricationThe unit requires no extra lubrication.ConnectionsMain switchWarningAlways turn off the main switch or isolate thepower supply and disconnect the air supply beforeconnecting or disconnecting the feeder, the controlboard or any of the circuit boards.IRO/ ROJ Tool kitIt is recommended to use IRO tool kit, with specialisedtools, to ensure easy and correct disassembly/ assemblyof IRO feeders during maintenance work.Please contact your local IRO service station for furtherinformation.Ref.
