2. Speed limit
Config (Key 1) Open configuration menu 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 Choose below options (4 on fig 01) Min Speed m/s Max Speed m/s Select by rotatory switch the maximum and minimum speed of the contact wire. Come back menu line (remember in the case of internal speed the interval between maximum and minimum speed is the tolerance against unexpected variations on the contact wire speed). This adjustment must be done always, even there is encoder o no If there is a big range of speed (maximum speed >> minimum speed) it will generate a big electric noise in the equipment. The user must find the balance between both things: electrical noise and speed tolerance. 3. Frequency adjustment Config (Key 1) Open configuration menu By rotary switch (4 on fig 01) Choose option channel defectomat and push; then appears a menu as above picture By rotary switch Select Frequency kHz , push and it will appear a list with all frequency possible: between 1 and 1000 kHz. Consider that the coils we are using only (4 on fig 01) accept maximum of 100 kHz The frequency to be selected will depend of the deepness and detail to analyze; in the Trolley 1 kHz of frequency is a maximum deepness of 6 mm . In general the formula to recognize the maximum deepness of insight is: 25f50 mm ; where f is the frequency of the Defectomat in Hz . This action is only done in the defectomat channels; In the cas of ferromat in the 2o channel there is not possible this option. 4. Filters adjustment
Config (Key 1) Open configuration menu By rotary switch Choose option channel defectomat and push; then appears a menu (4 on fig 01) as below picture By rotary switch Select Filter Corr, and push; then will be open a window named Change Filter Corr -4..4 . It means that the parameter range is between -4 to 4 (4 on fig 01) through 0, so 9 values in total. in normal operation the values of this parameter should be between [-1 0 1]. This parameter open or close the electronic filter of the equipment; if the value is near 4 the filter is practically close and the equipment couldn’t detect defect. If the value is near -4 will be electromagnetic noise and maybe will obtain wrongly defects The values can be adjusted by rotary switch in both sides as the arrows shows This action must be done in the case we use a second channel
5. Gain adjustment Config (Key 1) Open configuration menu By rotary switch Choose option channel defectomat and push; then appears a menu (4 on fig 01) as below picture By rotary switch Select Gain dB , push above ; then will be open the windows with title Change Gain =…71.9 . (4 on fig 01)
By rotary switch you can adjust the gain value with a resolution of 0,1 db that means gain or lost 1% of the signal. This action must be done in the case we use a second channel
6. Threshold adjustment Config (Key 1) Open configuration menu By rotary switch Choose option Analyse defectomat and push; then appears a menu (4 on fig 01) as below picture By rotary switch Choose below options (4 on fig 01) F1.Threshold% (slight defect) F2.Threshold% (sever defect) Each time each option has been select will be open a window that let adjust the threshold with a resolution of 5% (the levels can be adjusted from 5% to 5%) . This action must be done in the case we use a second channel 7. Mark assignment Config (Key 1) Open configuration menu By rotary switch Choose option Mark assignment and push; then appears a menu as (4 on fig 01) below picture By rotary switch First, ensure the option Marking output is on; if not the output signals (4 on fig 01) will not be open in any case. To change the status of this option you should select by the rotary switch, push and select on of the menu that presents. Then select Marking Equipment Push and will open a list, select M1..M4 (it means all the output signals are potentially open) select: Mark Assignment CH1 Mark Assignment CH2 Will be open a table as you can see in the picture (left below side of the screen), select each output of the equipment: M1 a M4; a defect slight or sever in each one of the two channels, it is possible assign logical operations as F1&F2. The option no will be used to not assign any signal in the correspondent output.
