G.3.1 Air Pressure Gauge

The pressure gauge measures air pressures at themain nozzles, sub nozzles, and other parts of theweaving machine.

Specifications

(1) Measuring object: Compressed air

(2) Applicable pressure range: 0 to 1000 kPa

(3) Applicable air temperature: 0 to 50 °C

(4) Applicable humidity: 85% RH max.

(without dew condensation)

(5) Power source:Lithium battery ER6VM made by Toshiba

Output: 3.6 VDCService life: 3,000 hours or more

(6) Other functions:Automatic power-OFF feature

Operation

(1) Press POWER button 1 while applying nopressure to the pressure gauge, and checkthat the least significant digit on pressure indi-cator 2 is within ± 5. If not, adjust it with zerobalancer 3.

NOTE: Polarity lamp 4 comes on only whenminus, and off when plus.

(2) Insert plug 5 into the coupler of the weavingmachine.

G.3 - 4


(3) Press POWER button 1, and the pressuregauge will start measuring.While HOLD button 6 is held down, the gaugeretains the measuring result.

(4) Press POWER button 1 again to power off.

NOTE: The automatic power-off feature willautomatically cut off power after approx. 3 min-utes from the last operation, without pressingthe POWER button.

Cautions:

• Never apply this gauge to liquid.

• Do not measure air pressures exceeding theapplicable pressure range.

Maintenance

If the "LOBAT" appears on indicator 7 telling thatthe battery output has lowered, open battery cover8 and replace the battery with a new one.

Order the battery with a parts number 65200-02000-**.

G.3 - 5


G.3.2 Stroboscope

The stroboscope allows you to measure a state ofmotions at a certain timing in fast revolution opera-tion of the weaving machine.

Specifications

(1) Synchronous revolution range:300-1200 rpm

(2) Accuracy in each revolution range:± 1 rpm at 300-900 rpm± 10 rpm at 1000-1200 rpm

(3) Pin-delay angle setting range:Turning setting knob 1 can set an arbitrary pin-delay angle (crank angle) of the weavingmachine within a continuous range from 0° to359°. The set angle will appear on indicator 2.

(1) Never use the stroboscope in a place full of inflammable gas, or in an atmosphere where there is the danger of explosion.

(2) Do not use the stroboscope anyplace where its inside may be subjected to water drops or the like. There is a possibility of electric shock or short circuit.

(3) While the stroboscope is in operation, do not look directly at the flash lamp. Your visual acuity may be damaged.

(4) Prior to checking the inside of the strobo-scope, be sure to unplug the power connec-tor. There is a possibility of electric shock.

G.3 - 6


(4) Synchronization (required for 1-6 color mea-suring drum)Pressing DIVIDE/MODE switch 3 to theDIVIDE position cycles through numerals 1 to4 on indicator 2 and accordingly switches thestrobe light emission cycle or the monitoringtiming of the posture of weft inserted from amain nozzle as listed in the table below.

After setting the monitoring timing, be sure topress DIVIDE/MODE switch 3 to the MODEposition.

(5) Shifted angle indication by the reset functionWhen the pin-delay angle preset by settingknob 1 is displayed on indicator 2, turningPOWER switch 4 to the RESET positionresets the indication of the current monitoringangle to zero. After that, turning setting knob 1displays the degrees shifted from that monitor-ing angle.

Operation

(1) Plug power cord 6 of the stroboscope into the100 VAC receptacle provided on the front sideof control box 5 at the right rear of the weavingmachine.

(2) Plug signal cord 7 of the stroboscope into thereceptacle prepared near the above 100 VACreceptacle on the rear side of control box 5.

G.3 - 7


(3) Run the weaving machine and turn POWERswitch 4 of the stroboscope to the ON position.Indicator 2 displays the actual machine speed(rpm) while showing the cursor on the rpmfield.

(4) Press DIVIDE/MODE switch 3 to the DIVIDEposition to set the desired number specifyingthe strobe light emission cycle (1 through 4).

(5) Press DIVIDE/MODE switch 3 to the MODEposition.Indicator 2 displays zero degree while showingthe cursor on the deg. field.

(6) Point the flash lamp towards the object, thenturn setting knob 1 while monitoring the crankangle on indicator 2 until you can observe theposture of weft.

(7) After completion of observation, turn off powerswitch 4.

(8) Disconnect power cord 6 and signal cord 7from the control box.

Example: Mix weaving

1) Press DIVIDE/MODE switch 3 to the DIVIDEposition to set the strobe light emission cycleto 2.

2) Press DIVIDE/MODE switch 3 to the MODEposition to display the degree.

3) Each time you press DIVIDE/MODE switch 3,you can observe wefts discriminating betweenwefts 1 and 2.

NOTE: Only when the cursor lies on the rpm field, itis possible to switch the strobe light emission cycleor the monitoring timing.

G.3 - 8


G.3.3 Circuit Tester

The circuit tester measures DC and AC voltages,and resistance applied in the weaving machine andthe related devices in order to facilitate mainte-nance of those electrical parts and troubleshootingof defective parts.

Specifications

(1) Measuring range (at 23 ±5°C, 80% RH):DC voltage 200 mV - 500VAC voltage 2V - 500VResistance 200 Ω - 20 MΩConductivity 1.5 kΩ - 15 kΩ

(2) Buzzer function:The buzzer built in the circuit tester sounds atany of the following:

a) when function switch 1 is switched,

b) when the circuit is conducting, or

c) when the measuring range is switched up.

(3) Measuring range switching:Full automatic ranging

(4) Indication frequency:2 times/sec.

(5) Batteries:Two LR-44 lithium batteriesService life: Approx. 80 hours in

continuous operation

G.3 - 9

0-200 gr for high-tension range

Adjustment

(1) Connect pick-up head 2 to meter 1.

(2) Set SELECTOR knob 3 to the CH position andcheck that pointer 4 indicates mid-scale, whichis CH position 5. If not, adjust it with ZERO-ADJ knob 6.

(3) Set SELECTOR knob 3 to the R1 (low tension)or R2 (high tension) position.

(4) Check that pointer 4 points 0 on the scale. Ifnot, adjust it with ZERO-ADJ knob 6.

Operation

(1) Apply weft 7 to be measured to pick-up head 2as shown in the left figure, then read the tension in grams while keeping the weft asstraight as possible.

NOTE: If the weft is routed in the reverse path(wrong path), it is impossible to measure it.

(2) To measure the tension of warp 8, set pick-uphead 2 at the center of the warp span betweeneasing roller 9 and dropper 11 placed at thetail of dropper box 10.

G.3.7 Tension Meter (Belt Tension Gauge)

This gauge measures the tension of the V belt ortiming belt for numerical tension control.

(1) Set the crank angle to cross timing ±180degrees.

(2) Press the Power button 1 to turn the powerON.“0000” appears on the LCD screen 2.

(3) Bring the head 3 close to the measuring part(Table 1) and flip the belt while throwing thetarget light.

Keep the distance between the belt and headwithin 2 cm, and keep the light vertical to thebelt. (Fig.2)

(4) Upon successful tension measurement, aclicking tone is heard and the belt vibrationcount appears on the LCD screen 2.Adjust the belt tension for satisfaction of thetarget tension range (Table 1).If the tension is lower than the target value,increase the belt tension. If higher, decreasethe tension.

NOTE: If the used belt is to be reused withoutreplacement with a new one, measure the tensionbefore removal and set the tension to the levelbefore removal. If the original tension is unknown,set it to the tension after use in Table 1.

Do not use it while the machine is in operation. A serious accident may occur when a hand or a meter may touch or get caught in the belt.

> When the numerical value of the measured tension is out of the range, adjust the tension with tension bolts.> Be sure to confirm that the belt will not swing and touch the cover during a trial operation. Raise the tension within the

range of the designated tension when the belt swings too much.> The timing belt of the positive cam or the positive dobby is changed by JAT810, but there is no change in frequency

(Hz) of the designated tension.

Measure in the center between pulleys.

Measure from the outer side.
