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
1. Equipment CI 2.812 with 2 channels DF
2. 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)
3. 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.
4. Coil support to sustain and positioning in the right place 5. 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 It is very important to ensure that the equipment detect speed adjustment the defects or report attenuated despite the equipment through the coil 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 Need to be consider two points adjustment ? 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 insert frequencies that are not aligned with the contact wire speed. 探测频率越大，可探测深度就越小 (lower are the defects that we can analyze) The frequencies in the equipment are from 1 to 100 kHz. ? With 1 kHz we can analyze well until 3.5 mm in CuOF and 4 mm for CuMg ? With 10 Khz we can analyze well until 1 mm for CuOF and 1.2 mm the CuMg ? With value of 100 kHz (bigger frequency) we can analyze 0,35 mm in the CuOF and 0.4 mm in the CuMg . 4-Filters It is very critical adjustment because in case of wrong set-up the equipment will not detect defects. Originally the value is 0 and must be keep this value 5-Gain adjustment The value can be adjusted by the experience It is a logarithmic scale (No lineal scale) from 0 to 70 db, it means the signal can be multiplied maximum by 3.162 times. To double the value of the signal it is enough increase the gain on 6 db ; each db of variation the signal increase o decrease 12% 6-极限 adjustment 7-Mark assignment 8-Encoder adjustment
It can be adjusted in tenths of Db. The recommended values are bigger than > 50 db in order to be sure the sensibility of the equipment is good This parameter is to define when the defect is not important (it means it will not be register as a defect), slight or severe. The adjustment is % from 0 to 100 %. The CI 2.812 has 2 output of defects by channel; slight or sever defect (DLL, DG) , so there are 2 channels with a total of 4 defect output. We can defined every defect in which output can be register In this adjustment we can define the progress represented by each pulse of the equipment Adjustment: process

In the case that there is not encoder the Contact wire speed adjustment through the coil must be adjusted manually. Config (Key 1) 切换到参数调整界面 By rotary switch Choose option line and push (4 on fig 01) The process to push by the rotary switch is universal to activate of the menus in each option By rotary switch Select below options (4 on fig 01) Speed clock ref Speed clock set Speed clock test Push and select by rotary switch, the internal on the 3 cases. After select these options come back to the menu line by rotary switch. With this option the CI 2.812 consider that the speed of the contact wire will be manually set-up by the user in m/s By rotary switch Choose option Internal Speed in m/s (4 on fig 01) Set-up the speed of the contact wire and come back to the menu line
