Led CH1 and CH2 STATE
1 Flash Short-circuit in loop
2 Flashes Disconnected loop or frequency too low.
3 Flashes Frequency too high
Led on Vehicle detection
Sensibility (SENS)
Each channel has 4 configurable sensibility levels. This sensibility is specified as
δ
L/L [%]: the
minimum change (
δ
L), the loop’s inductance must suffer, divided the loop’s inductance (with no
vehicle present). A cars typical sensibility is
δ
L/L=3% approximately.

Outputs
8.1 Pulsed
The output signal activates when the vehicle enters the loop and remains on for 120 ms
approximately.
