Once complete, seal the loop slots with epoxy compound or bitumen filler. (It is recommended this is only done

after the detector has been connected and tested).

Please note: The MD2010 must be reset (Dip 9 below) every time a setting change is made to the

Dip-switch 1 – Freq. (Frequency):-

This setting is used in cases where two or more loop detectors and sensing loops have been installed. (The

sensing loops and detectors should be positioned at least 2m apart). Set one detector to HI frequency and the

other set to LO frequency to minimize the effects of crosstalk between the two systems.

OFF = Low frequency

ON = High frequency

Dip-switch 2 and 3 – Sensitivity:-

This setting determines the necessary change to the loop frequency to trigger the detector, as

metal passes across the sensing loop area.

Dip-switch 4 - Boost mode:-

If boost mode is ON the detector will immediately switch to high sensitivity once activated.

As soon as the vehicle is no longer being detected the sensitivity reverts back to what has been set on

dipswitch 2 and 3.

This mode is used when the height of the undercarriage of a vehicle increases as it passes over the sensing

loop.

OFF =

No boost active

ON =

Boost mode active

Dip-switch 5 – Permanent presence or limited presence mode:- (When presence mode selected.
