FA306 drawframes Troubleshooting Trina hand textile machinery and equipment for your textile finishing. The process of operation of the machine suddenly stopped the touchscreen display touch screen has no trouble many failures will stop after a failure, automatically eliminate the fault recovery fault records, such as door switches, emergency stop, and jog button, a stop button action will stop, but it does not report failure. So this time you should check the parking touchscreen There are no page fault alarm, fault records if there is a blank page, indicating that the emergency stop or door switch failure, if not, should be to move the button and the stop button actions caused, of course, failure or PLC PLC input grounding place (if the proximity switch shorted to ground) will cause no alarm failure. . Reported touchscreen ** fault, but the fault is normal, even to the point of failure short (running NC input) as well as the phenomenon. The failure if it occurs after shorting input that fault should be PLC inputs damaged by program adjustments and reserve additional inputs rewiring resolved (with spare replacement spare PLC PLC). Koyo SH PLC PLC inputs were several cases of damage to the phenomenon, the quality of the internal circuit board components. A textile mill in Shandong are often damaged, replace inputs are resolved. You can also turn off the touch screen settings disabled plugging photoelectric function, will also be required to avoid the failure to find the troublesome computers. Will automatically pop up touch-screen display is not according to the actual fault message is displayed according to the model nor Shenyang Textile Machinery lazy engineers put more than a minute and making a touch-screen model program, press the touch screen in the middle of a touch screen is powered models Selection Dialog box, select the corresponding model after it. The problem is that the error was caused by a touch screen at power up. FA326 and FA306 PLC program is not the same, not the same warning message is displayed. How to adjust the brightness If the touch screen brightness does not meet the requirements, you can adjust the brightness. Since the touch screen is set at the factory, press the screen left and right corners can not enter the system screen. Turn the screen back below the battery compartment, duty bottom right four miniature toggle switch. All the switches are at the bottom of it, Shenyang FA306 fourth general switch on top, locked for the touch screen to enter the system screen. Do not mess press, otherwise it will lead to the loss of touch screen programming. Photoelectric switch problem, deal with their own, especially wiring. Too thin, easily broken or artificial pressure to cause the ground inside the machine. Old PLC input program can be used, and the newly purchased PLC program input program delivery speed is zero, the tube length does not go? A: The need to set PLC special register to enable high-speed counter I0 (original program) or external interrupt inputs (Later, I designed the program), or it may not work I0. This register is only good enough programmer or computer settings, unlike other PLC high-speed counter can be set by the program and other functions. Replace other drive needs attention? A: It should be noted redesigned drive parameters and wiring, some drive is not free parking (coasting) terminal can be set to switch to the second deceleration time. Setting data acceleration time of 6 seconds deceleration time of 1.5 seconds Terminal 1 run panel to set the corresponding frequency Multi-speed terminal 2, terminal 3 corresponding to 15HZ free parking (or the second deceleration time is set about six seconds) frequency source panel operation command terminal other terminals Function Default namely can, pay attention to the corresponding motor protection parameters. photoelectric controller inside the 12V transformer (220V variant 12V) is broken, causes and solutions burned because photovoltaic electricity 24 hours, as well as machine after photoelectric 12V power transformer short circuit overload cause burn, plastic generally brittle aging overheating can power box inside 24V 24V switching power supply, regardless of the polarity of the output directly to the original transformer transformer not removed, repaired even better than the real transformer, not of 24 volts is too high.
