Dual channelinductive loop vehicle detector specification:  
Dual channelinductive loop vehicle detector main features: 
Automatic Frequency Selection: Automatic Frequency Selection option allows the detector to automatically select the best operating frequency that will achieve the lowest loop noise and maximum signal strength.
Flexibility: Front panel mounted DIL switch provides many user selected functions without the need to access the internal circuitry. Channel multiplex circuitry eliminates crosstalk interference between the two loops connected to this detector regardless of the proximity.
Direction Logic capability: Internal links optionally modify the outputs to indicate the direction of travel of a vehicle. Outputs are provided for direction A to B and B to A. This option is used for entry/ exit counting, free exit and similar applications.
Selectable Permanent Presence: With this feature selected the output of the presence relay will be maintained for an indefinite period, thereby eliminating premature barrier/gate/door closure and possible vehicle damage.
Fault Monitor: A fault indication is provided in the event of the loop input becoming faulty, or alternatively if the loop is out of the tuning range. This feature will help in localising the fault in the event of a maintenance call-out. 
Loop Isolation Protection: The loop isolation transformer provides protection against lightning and transient damage and allows for operation with single point to ground sensor loops.
Diagnostic Capabilities: The software of this unit allows comprehensive diagnostics capabilities in conjunction with separate DU100 hand-held diagnostics readout. Advanced diagnostics features are covered by International patents.
1.Q1: If the detector is not working?
   A1: Press reset
2.Q2: If red led indicator is not fully lit?
   A2: Check for power supply
3. Q3: If green led indicator blinks slowly?
   A3: It maybe because the loop is short circuit or the no: of turns is not enough.
4. Q4: If green led indicator blinks slowly?
   A4: It maybe because the loop is open or the no: of turns is too many.
5. Q5: If no: of turns is not enough?
    A5: Lower the frequency (if the frequency is still too high, you must add more turns).
6. Q6: If no: of turns is too many?
   A6: Higher the frequency (if the frequency is still too low, you must remove some turns).
