Inductance:100uH ~ 300uH(recommended) Dimension:78x40x108 mm (L x W x H)
Loop Installation
The loop(heat-resisting Teflon wire)is normally buried in a parallelogram form gap. After the test, seal the gap with liquid pitch. 1 to 2 circles of loops should be added as compensation when there are metal things under the ground. And the inductance should be kept at 150-300uH.The lead time must be twisted together closely, so as to prevent the disturbance caused by shock.
Relay Outputs
| Relay 1 output | DIP8=ON | Forever exist: the relay 1 will keep closed/connected when the car stay above the loop until the car leaves the loop. |
| DIP8=OFF | 10 mins exist: the relay 1 will keep closed/ connected for 10 mins when the car stay above the loop.After 10 mins, the detector turns back to the previous state. | |
| Relay 2 output | DIP7= ON | Leave impulse: when the car leaves the loop, the output relay2 will close/connect for 0.5S and then open/disconnect. |
| DIP7= OFF | Enter impulse: when the car enters the loop, the output relay2 will close/connect for 0.5S and then open/disconnect. |
