 Symptoms                                              Solution

1. If the detector is nor working--------Press reset
2. If red led indicator is not fully it -----Check for powedr supply
3. If green led indicator :
  a) Blinks slowly--------------------It maybe because the loop is short circuit or the no: of turns
is not enough.                
  b) blinks faster---------------------It maybe because the loop is open or the no: of turns is too many.
4. If no: of turns is not enough---------Lower the frequency (if the frequency is still too high, you must add more turns).
5. If no: of turns is too many----------Higher the frequency (if the frequency is still too low, you must remove some turns).

4. Description:

(1) Loop detectors in recent years have become a popular tool having innumerable applications in policing,

right from surveillance operations to traffic control. Automation of gates and doors

has become a popular usage of the loop detector.

(2) The loop consists of several loops of wire and consideration ,should be giving to the loop

sensitivity when installing on different surfaces. Setting the correct sensitivity allows the loop

to operate with maximum detection (8 levels via a trimpot). When detection occurs,

the detector energises 2 relays for the output (each can be configured individually).

This energising of the relay can be configured into different modes, by selecting the respective dip switch.

(3) Fault Output:   Blinks slowly: It maybe because the loop is short circuit or the no:of turns is not enough.
Blinks faster: It maybe because the loop is open or the no: of turns is too many.

(4) Modes of operation:

The LD-200 series detector may be configured for any one of the following modes:

    Presence Mode

    Pulse Mode

 AB Logic Presence Mode(Barrier Operation)

 AB Logic Pulse Mode(Counting Logic)

5. Connections:

loop detector CE,RoHS certification
