| Single Channel Loop Detector Traffic Barrier Gate 11-Pin Submagnal  Model Number:NBLD100 Single channel vehicle loop detector A)Single channel vehicle loop detector Description:
 Loop detectors in recent years have become a popular tool having innumerable applications in policing, right from surveillance operations to traffic control.  The loop consists of several loops of wire and consideration should be giving to the loop sensitivity when installing on different surfaces. Setting the correct sensitivity allows the loop to operate with maximum detection (16 levels via a trimpot). When detection occurs, the detector energises 2 relays for the output (each can be configured individually). This energising of the relay can be configured into different modes, by selecting the respective dip switch. Sensitivity Selection: Sensitivity of the loop can be adjusted by the trimpot labeled “Sensitivity”. User

F)Troubleshooting:
| Symptoms | Solution | |
| If the detector is not working | Press reset | |
| If red led indicator is not fully lit | Check for power supply | |
| 
 | Blinks slowly | It maybe because the loop is short circuit or the no: of turns is not enough. | 
| Blinks faster | It maybe because the loop is open or the no: of turns is too many. | |
| If no: of turns is not enough | Lower the frequency (if the frequency is still too high, you must add more turns). | |
| If no: of turns is too many | Higher the frequency (if the frequency is still too low, you must remove some turns). | |
