-Connect the cable of the power supply to the NFB inside the control box, and make sure cables of eachphase are connected tight and parallel.

(3)(3)(3)(3) ElectricalElectricalElectricalElectrical cablecablecablecable sizesizesizesize

-Thickness of cables connected from the power supply to the loom should be regularly thicker than AWG10(Equivalent to 5.5mm2) for AC220 V, and thicker than AWG12 (Equivalent to 3.5mm2) for AC380 V. Choose theright electrical cable size considering following items:a) Power voltageb) Distance from the power supply to the loomc) Never drop the power voltage of the loom more than 10% at the start of the main motor. Since at AC 200 V,about 200 A inrush current instantly flows into the crank machine and 300 A into the cam dobby machine in therush start, selecting excessively thin electrical cables may lead to larger voltage descent, which lessensstarting power, compromises a grade of cloth, and results in malfunctions in electric parts.

CAUTION(4)Leakage(4)Leakage(4)Leakage(4)Leakage breakerbreakerbreakerbreaker installationinstallationinstallationinstallation-In order to prevent accidents such as fire or electric shock, install a leakage breaker in thefront of the NFB (provide the power source to the NFB through a leakage breaker).

CAUTIONCAUTIONCAUTIONCAUTION-Make sure the interception capacity of the NFB on the factory side is larger than the current rating of the loommentioned above.-when short-circuit accidents occur on the loom side, estimated short-circuit current flowing into the NFB willbe less than the interception capacity.

(7)(7)(7)(7) VibrationVibrationVibrationVibration (cautions(cautions(cautions(cautions forforforfor installiinstalliinstalliinstallinnnngggg thethethethe loomloomloomloom machine)machine)machine)machine)-Perform sound fundamental construction before setting up the loom machine to avoid excessive vibration.Vibration may result in connection faults in cable-connected parts and it may lead to machine malfunctions orbreakages.[[[[HumidityHumidityHumidityHumidity ManagementManagementManagementManagement]]]]-The controller is constituted of precision electric components. Take much care of humidity. Do not use thecontroller when condensation is forming on it. Using the controller in such a state may result in accidents suchas electric shock and breakages of electric components. Generally, desiccants are put into the control box toprevent high humidity.-If the loom will not be operated for a long time, which often happens in long holidays, condensation may formon electric components. Remove condensation before you operate the loom.

Prevention procedure:-When you do not use the loom for a long time, turn off the main switch of the NFB and run an air conditionerto ventilate air inside a factory for a few hours. At that time, keep doors of the control box open.-When you want to restart the machine, open doors of the control box and ventilate a few hours before restart.After that, turn the NFB main switch on around 30 minutes before restart and close the doors.

NOTENOTENOTENOTE-It is safer to take the control unit out of the loom and keep it in a drying place when you do not operate theloom for more than a month.-When you store the PCBs, wrap them with electricity-conductive sheets (such as aluminum foils) and putthem in a drying room or put them in a sealed box in which desiccants are packed.

4.14.14.14.1 PrinciplesPrinciplesPrinciplesPrinciplesA loom machine is consisted of the following parts:

1- Beam: winding up the warp yarns (longitudinal threads).2- Held frame: raising the warp yarns up and down.3- Reed: battening (or pressing) the weft yarns (transverse threads).4-Take-up roller: rolling up the woven cloth.

Plus, some systems or devices are used for inserting weft yarns.

A group of warp yarns is wound on to a held which rises up and down.

These helds are attached to the held frame.

Held frames are sometimes required more than three. How many held frames you need depend on the way tointersect warp and weft yarns.

A reed has lattices and the number of lattices a reed has depends on the number of warp yarns used.

Weft yarns are inserted into the shed created by vertical movement of held frames and a reed battens the yarnsas Fig. 4.1 shown below.

A beam and a take-up roller are put together with a gear and the roller takes up the woven cloth at presetrevolution frequency.

6. Brake Circuit

- 22 -

6.16.16.16.1 OutlineOutlineOutlineOutlineThe brake circuit stops the loom at the normal position by having the electromagnetic brake work when thecircuit receives a stop signal. There are two types of circuits: High-voltage brake circuit and Low-voltage brakecircuit. Those circuits are controlled by the control unit.

(1) High voltage brake circuit (B0-B and B0-B1)-This circuit works instantaneously to stop the loom quickly.-This circuit is constituted of full-wave rectified 80V AC power and switching circuit.

(2) Low voltage brake circuit (B0-B1)-This brake is used to keep the loom staying at the same position while the loom stops.-By switching a brake switch off, you can stop braking.-This circuit is constituted of full-wave-rectified 18 V AC power and the switching circuit.

6.26.26.26.2 FeaturesFeaturesFeaturesFeaturesBy loading the overcurrent-detecting circuit, this brake circuit became more safe and reliable.When overcurrent is detected in low voltage brake, LED27 (BR.ALML) lights up, and when overcurrect isdetected in high voltage brake, LED28 (BR.ALMH) lights up.

CAUTIONCAUTIONCAUTIONCAUTION-When LED27 or LED28 lights up, turn off the power and solve problems as soon as possible.-Brake unit charges high voltage inside itself even after power shutdown. To avoid electric shock, wait for 20seconds after power shutdown when you want to take out the break unit.

6.3.2 Adjustment by the Reverse ControlThe reverse control is the function to gain braking power at the right moment when the loom stops by rotatingthe main motor reverse. Using the electromagnetic brake at the same time, you can stop the loom quicker. Usethis function when the loom can not stop at the position adjusted in 6.3.1 Adjustment with the braking delay timefrom F-TMG emission.

Adjust the reverse control time-Adjust with SW8-5, SW8-6(R-BRK)-You can select 0,100,150, or 200msec for the time setting

NOTENOTENOTENOTEThe longer the reverse control time, the quicker the loom stops. Avoid setting excessively long time toprevent the loom from rotating reverse.

[[[[ProcedureProcedureProcedureProcedure 3333]]]]Adjust the weft yarn signal input timing with TP1 (F-TMG), TP5, and TP3.

The feeler does not judge the original F-TMG input but the F-TMG signal adjusted by VR5 and VR6 (when acontact type is N.C).The adjusted signal is judgment F-TMG signal, and the feeler judges if weft signals are being inserted in thejudgment F-TMG signal.
