When OP shows "#? ### PLC ERROR", and displays the value of the box "#####" rather than value, this kind of failure is often between the PLC and OP communication caused by the no a. 1. Check the adapter and its connection interface (dual OP inspection DP connector); adapter side has two lights are flashing when normal; 2, check the PLC's power supply is normal: Look 24V DC on the cabinet is normal, Please handle the power module failure is not normal according to the circuit diagram. Common reasons are: 1) AC220V power supply is not normal; 2) DC24V line is grounded. 3, check whether the PLC red and yellow light, if there is, please contact with Randy. Glass deformed mainly from two aspects, the first issue is the precision roller, the second is the problem of uneven stress. 1.1 Roller presence flatness problems caused by bad tempered 1.1.1 heating roller deformation generally horizontal roller furnace steel roller is made of fused quartz or ceramic material, has good thermal shock resistance and thermal stability, but because of unevenness sometimes its internal structure, at the time of heating may cause thermal deformation particularly at high temperatures. Hot roller deformation caused by the bending roller inevitable, but also inevitably lead to deformation on the surface of the glass movement. 1.1.2 when the roller is worn roller after prolonged use and repeated cleaning, will inevitably lead to wear roller, especially in the clean-up rollers bonding more solid impurities, usually using grinding methods to clean up, long-term use and multiple roller mill clean-up will lead to loss of unevenness. On the one hand appear in the same rollers or appear eccentric uneven thickness between the roller and the roller on the other hand sometimes, but at the same time because they do not also replace the use of uneven thickness of the old roller or different degree of wear roller simultaneously also It will lead to uneven thickness roller. These results appear will result in uneven running surface of the roller, the glass in this uneven rollers eventually heated to the softening temperature, and conduct drive uneven rollers, softened glass there will be deformed, this deformation reservations glass After the glass to be reinforced, toughened glass will after deformation. 1.1.3 grilles roller deformation of the glass in the heating furnace was quickly transferred to the wind gate rollers, when the glass is still in a softened state, if the deformation roller grille inevitably affect the flatness of the glass, and the most likely to make the wind gate The main roller deformation there are two reasons: First, the drive roller bend, and second insulating material roller surface defects.
