When the loom is stopped for some reason after the push button is pressed or the start is stopped, the loom will perform a series of tasks according to a predetermined procedure. At this moment, the red warning The light will flash rapidly to remind the operator. Until the loom stops completely, the warning light will stop blinking, then the operator can proceed to the next step.

Note: It is extremely dangerous to operate the loom during the flashing of the warning light, which may endanger the personal safety!

2.4 Loom button abnormal status prompt

When the system detects that the operation button of the loom has been pressed for a long time, it will display the message that the related button has been pressed on the main screen of the screen, and can judge whether the related button is stuck and can not be reset according to the prompt The situation, to prevent loom unexpected movements.

2.5 Loom signal status description

In order to facilitate the loom factory to check the fault or loom state according to their habits, the display state of four color lamp can be set freely, each lamp respectively have four kinds of state: Off, On, Slow flash, Fast flash. Each state of loom can be independently assigned a state of each color lamp.

The factory configuration is as follows:
 

When a mechanic input signal is tested, the red light flashes when there is a new input signal.

The status description in the above table only makes sense if the loom is in a specific single state. When two or more weaving machine states occur at the same time, for example, when the stop button is pressed and the weft cutting detection function is turned off, the green light and the yellow light will be on at the same time. For the situation that many of the semaphores are on at the same time, Refer to the relevant information on the screen to determine the cause.

3.4 Parameters Setting

Press [Param] in the status window to go to the "Parameter" screen. There are twelve items in this screen and press the corresponding item to enter the window for each function.
 

3.4.1 Prewinder Setting

Click item 1 on the main screen of parameter setting to enter the parameter setting screen of weft feeder
 

Prewinder Setting

Automatic Prewinder: It means that when a prewinder associated with an optional prewinder has no weft, the selected equivalent weft needle is replaced to complete the color selection function.

At this point loom lights will continue to flash to indicate this happens. If the 

missing prewinder state returns to normal, the corresponding prewinders will return to normal weaving.

Tip 1: Automatic weft insertion is only possible if the prewinder is equipped with a weft thread sensor. In order to make the automatic filling work properly, the weft feeder must be correctly connected to the corresponding weft selecting needle, that is, the prewinder number must match with the weft picking weft number one by one.

Tip 2: When auto-fill setting, if you want to do only partial fill-in operation, then the reserve number of the weft feeder that does not need to do fill-in operation can be set as its own number.

Tip 3: When the automatic fill-in function is enabled, you should pay attention to check the settings of the automatic fill-in parameters after modifying the color-selecting pattern to ensure the automatic fill-in function is normal.

3.4.2 Filling Detection

Click on item 2 in the parameter setting screen to enter the filling detection setting screen.

Friction between the yarn and the weir piezoceramic hole produces an electrical signal that is sent to the processor and amplified, and the sensitivity of the signal is adjusted on the display.
 

Press [Save] button to save the parameters and press [Back] button to return to the "Parameter" screen. If you return directly from this screen without saving the parameters, then the changes are invalid. The settings of other parameters are the same.
 

The system supports weft detector with anti-double weft function. When more than one weft arrives at the cloth fell, the weaving machine will stop immediately.

detection parameters adjustment:

1) End of the weft angle adjustment

Turn the weaving machine until the right sword head yarn, check the loom angle at this time, for example, 300 °, subtract 10 ° from the angle, the value is the end of the weft angle. In this example, this value is 290 °. The end of the probe should be set as late as possible so that the probing time is as long as possible. However, the weft may be released at different times as the head of the sword vibrates as it enters the guide, so the detection must be completed earlier.

2) Filling detector gain adjustment

Before normal use of the weft detector, check whether the voltage value of the 

gain control signal of the weft detector (voltage between pins 4 and 4 of the four-core connector J3 on the main control board) is between 1 and 5 volts, This value can be adjusted by the weft detector gain parameter. The larger the value, the larger the voltage value of the gain control signal, and the greater the output signal strength of the weft detector, the easier it is to detect the weft. The different weft detectors correspond to different values ​​of this parameter, generally in the range of 3 - 12, with a default value of 8.

Into the machine test input signal monitoring screen, quickly pull a weft to observe whether the system detects the weft signal, if there is no weft signal, you should gradually adjust the parameters until the weft signal is detected.

If we need to change the sensitivity of weft varieties, the recommended adjustment is to set the weft pick-up gain to a higher value (for example, 10) in order to drive, and then gradually reduce the gain until the weft looper stops And stop, and then increase the value of 2 to 3 units.

3) Filling filter value adjustment

The filling detection includes filling detection and double filling detection. The filling detection time can be set independently for each filling picking channel. The filling and double filling filter values ​​are adjusted by 0.5 ms. If there is filling stop and actually not weft, filling detection is too sensitive, then we can adjust the value of "weft and weft filter" of the signal of the road and vice versa; if there is double filling stop, Double filling detection is too sensitive, then the "double filling filter" value adjusted up, otherwise small; if this adjustment is still not satisfactory, you can properly adjust the "weft detector gain" The value of the smaller the value tends to be reported off filling stop, the greater the more tend to double filling stop.

Weft insertion filter values ​​must be set as low as possible, but depend on the weft's roughness. For smooth weft yarns, this value is 1 to 4; for rough weft yarns, such as slub yarns, this value must be increased (eg 8 to 10) because this weft yarn can not always be in contact with the porcelain holes.

Note: In order to ensure the normal operation of the weft feeler, the guide rod in front of the feeler must be adjusted so that the weft always remains in contact with the porcelain eye of the weft feeder.

3.4.3 Warp Detection

Click on item 6 in the parameter setting screen to enter the warp detection setting screen.
 

Description:

"Warp detection filter" refers to the control system to warp yarn input electrical signal control reaction. The filter value can be adjusted to ensure that the weaving machine can stop at any breakage. Filtration value of a total of 40 settings, the greater the setting value the lower the sensitivity, that is, the intensity of the electrical signal control system usually ignore, that is less prone to error stop phenomenon, but the setting value is too large may produce after menstruation Prolonged non-stop phenomenon; the other hand, the smaller the setting value, the higher the sensitivity is, the less likely to cause the phenomenon of non-stop menstruation, but the setting value is too small may cause a wrong stop phenomenon. Medium sensitivity for most fabrics, with a default of 10.

3.6.12 Double Weft and Empty Weft Programming

If you want to use this function, please ensure that this function is enabled on the "Function Option" screen.

Double Weft Weaving：Two weft yarns are insert into the same cloth fell at the same time during one weft insertion cycle. If no weft or only one weft yarn is insert into the cloth fell during double weft cycle, the loom will stop automatically. If you want to use this function, you only need to select two pick number in the same line of the color pattern. If the number of the selected pick in one line is more than two, the system will only use the first two pick numbers.

Empty Weft Weaving: This function means that the loom insert no weft yarn into the fell during normal weaving process to meet some special requirements. If there is a weft yarn inserting into the fell, the loom will stop during empty weft cycle. If you want to use this function, you only need to confirm that the specified line of the color pattern is blank.
