ASI in BOPP film production line applications and troubleshooting


. The investigation data repeater function that ASI: ASI communication when more than a certain length of cable, the cable carrying the signal information or noise due to attenuation affect the integrity of the data, the reception point to receive and recognize the right. And require repeaters, on the line in the plastic packet signal amplification, re-copy and copy the newly generated signal transmitted, the newly generated signal has a good waveform. Combination of symptoms,[link widoczny dla zalogowanych], suspected to relay the signal transmission problems caused by failure, resulting in transition temperature measurement. In the absence of spare parts for the case of repeaters, do the following experiment: Using ASIC302 the repeaters and the relatively unimportant ASIC103 normal area of the repeater to swap test, the 2-day trial ASIC302 working properly, and ASIC103 system 2 times the fault appears, you can see swap fault zone also occurred. Reversed by the multi-regional repeated experiments have proved that the repeater by ASIC302 unreliable due to the failure. To this end, the normal repeater installed in ASIC302, excluding auxiliary extruder 3 and 4 stop jumping the chain of failures. To ensure normal operation of production lines,[link widoczny dla zalogowanych], waiting for the new parts to make the following adjustment of the Q test: the normal priority repeaters can cause the temperature interlock installed in the parking ASIC302 bus, select the ASI cable length is shorter, and the length of about 120m only a temperature alarm without causing downtime ASIC103 interlock bus, temporarily install the repeaters,[link widoczny dla zalogowanych], and repeaters installed on the original side of the ASI cable docking 2. Note first stop when docking power ASI, ASI cable connected to the positive terminal positive and negative to the negative terminal. After boot found that removing its repeater hang on the ASI bus, temperature measurement module is installed in the terminal (1oom later) of the individual modules occasional flash of red, measuring temperature along with the occasional jump, and soon will automatically return to normal, Although the state of instability, but has not affected the normal operation of production lines. 2 months after the arrival of new models of repeaters, installed the symptoms disappear. 2.2ASI troubleshooting field failures from the station phenomenon: RUN lamp module from the station, FAUIJT lights, brought from the station's on-site device is not working, but does not affect the other from the station. Analysis: Due to a variety of interference signals the scene more, there are many variable frequency motor, high voltage generator, inverter, and ASIC103 selected unshielded bus cable, although the anti-jamming technology advanced, but it can also be transient interference. Coupled with continuous high temperature up to 50cc over the scene, could easily lead to failure from the station. Approach: (1) first manually dial the RESET switch to reset, if reset after the RUN light, FAULT lights out, after waiting for 2s if maintained properly, from the station to normal operation, cause of the malfunction signal from the station interference by other devices produced a transient fault. Shielding measures taken as soon as possible. f2) If the above in about 2s from the operator station module is displayed again FAULT, slave module must be replaced as soon as possible. Online replacement, If you are installing has not been defined address of the new module, the system will automatically recognize and give the new module address, address number and the same as before. If the new module has been defined number or address two or more need to also replace the new module will have to manually enter the address number. Completion of the work can make from the station into operation. 2.3 Power Failure Detection Module Fault phenomenon: the power detection module FAULT lights, the ASI brought FAULT lights from the station, the system can not run. Analysis and processing: the power detection module is the role of this test is normal and stable ASI system power. Manually dial the reset switch reset, continuous detection of power supply voltage with a multimeter lh, normal and stable voltage 30V, of asking the fault occurs again, replace the power detection module in accordance with the experience after the start, the failure also occur. Analysis is due to interference by other signals, while the meter is not detected. Surrounded by dozens of drive at the same time work, and its cable and ASI cables are placed in the same cable trench isolation may not cause interference, check the cable channel found that a serious mix,[link widoczny dla zalogowanych], sub-put and can not be separated again shielding the individual sections, complete boot failure disappears. 3 Conclusion Although the ASI bus, suitable for film production line applications,[link widoczny dla zalogowanych], but ASI bus to work, the quality of its hardware and application environment and the installation details are critical. ASI bus maintenance personnel should have the newer wide range of knowledge, which requires maintenance personnel to continue learning.
