This setting determines how long the relay remains active when a vehicle is stopped within the sensing loop

area.

ON = Permanent presence mode. The relay will remain active for as long as a vehicle is detected within the

sensing loop area. When the vehicle clears the sensing loop area, the relay will deactivate.

OFF = Limited presence mode. With limited presence mode on the detector will only activate the relay for 30

min.

If the vehicle has not moved out of the loop area after 25 min, the buzzer will sound to alert the user that the

relay will deactivate after another 5 min. Moving the vehicle across the sensing loop area again, after the relay

has deactivated, will re-activate the detector for 30 min.

Dip-switch 6 – Relay Response (when):- (Pulse mode only. See dip-switch 8)

This setting determines when the relay will activate.

OFF = PULSE ON DETECT. Relay activates immediately the vehicle is detected in the sensing loop area.

ON = PULSE ON UNDETECT. Relay activates immediately the vehicle leaves the sensing loop area.

Dip-switch 7 – Filter:-

This setting provides a 2 sec delay between when the metal object is detected and when the relays activate.

This option is used to prevent false activations when small or fast moving objects pass through the loop area.

This option can be used where an electric fence nearby is the cause of false activations.

If the object does not remain in the area for 2 sec the detector will not activate the relays.

Dip-switch 8 – Pulse mode or Presence mode:-

This setting determines how the relay responds to a vehicle standing still within the sensing loop

area.

ON = Presence mode. Relay will remain active, as per dip-switch 5 selection, for as

long as a vehicle is within the loop sensing area.

OFF = Pulse mode. Relay will activate for 1 sec only on entry or exit of sensing loop

area as set by dip-switch 6. To re-activate the vehicle must leave the sensing area

and re-enter.

Dip-switch 9 – Reset:-

Please note: The MD2010 must be reset every time a setting change is made to the Dip-switches!

To reset, switch Dip-switch 9 on for approximately 2 seconds and then off again. The detector then completes

the loop test routine.

On power up or reset the following will occur:-

Ensure the sensing loop area has been cleared of all loose pieces of metal, tools and vehicles

before powering up or resetting the detector!
