DEFECTOMAT CI 2.812 操作规程 硬件 Defectomat CI 2.812用于在线检测接触线拉丝机生产的接触线产品, it doesn’t include ferromat that is the reason why it is important to have 2 channels DF to analysis the surface and the inside contact wire Equipment CI 2.812 with 2 channels DF Connection cable from the equipment CI 2.812 to the coil (the distance of the cable should be not bigger than 50 m, and it is important to avoid avoid sharp bends in the cable route) Coil (even work with 2 channels DF one coil is enough) ; it is necessary 3 shapes of coil: one on service ,1 spare part and the last one in case of damage. Coil support to sustain and positioning in the right place 电源220 VAC 300 VA . The diameter of the coil must be adjusted to the Contact Wire to the sections from 85 to 150 mm2: 17 mm for 150 mm2 15 mm for 120 and 110 mm2 12 mm for 85 mm2. The diameter of the coil is important to ensure the sensibility of the signal. Necessaries adjustments 1- Contact wire speed adjustment through the coil It is very important to ensure that the equipment detect the defects or report attenuated despite the equipment is working properly The equipment can receive speed information through one encoder that constantly recognize the speed of the Contact Wire o adjusting internally the equipment setting up the theoretically the speed of the contact wire will be through the coil 2-Speed limit 2 limits, upper and lower that must be defined to the equipment CI 2.812. With encoder CI 2.812 only detects defects if the speed is inside of the limits. In the case of internal speed adjustment the CI 2.812 can detect and register defects even there are fluctuations in the speed of the contact wire that are not know for the equipment. 3- Frequency adjustment Need to be consider two points Speed of the contact wire Deepness of the defects we wanted to detect Faster is the speed of the contact wire greater will be the minimum frequency of work. The equipment CI 2.812 doesn’t allow inser
