Operating Instructions
1. Connect the power, ground, loop & output (See Terminal & Loop Connections).
2. Sensitivity of Loop 1 is set by switches `1` & `2` (See Function Settings).
3. Sensitivity of Loop 2 is set by switches `3` & `4` (See Function Settings).

Relay Function
As standard, both of the relays are Normally Open (N/O). To change Relay 2 to Normally Closed (N/C),
carefully open the detector housing and place the jumper (JP2) to the following position...
:Normally Open :Normally Closed
Note:- For additional information, please see side of loop detector
Function Settings
DIP Switches 1 & 2 :- Loop 1 sensitivity (4 steps)
DIP Switches 3 & 4 :- Loop 2 sensitivity (4 steps)
DIP Switch 5:- Frequency (High / Low)
DIP Switch 6:- Holding time (5 mins - Infinity)
Note:- Loop will recalibrate after 5 minutes constant detection
DIP Switch 7:- Direction detection
Note:- Directional operation is used for Traffic Management ONLY
DIP Switch 8:- Presence / Impulse selection
Note:- If Impulse operation is selected, the 1st loop to be activated will give a Presence signal when the
2nd loop is clear, a Pulse signal will then be given.

Installing a Loop
Rubberised insulated wire of 0.75-1.50mm²(awg 20 - awg 16), preferably multi-stranded.
Note:- High bed vehicles require larger loops.
Recommended depth to top of loop cable 25-50mm. (Maximum depth 65mm)
Loop slot MUST be sealed after cable has been installed and tested.
Use a flexible, weather proof sealant (i.e. Hot bitumen, Rubberised bitumen sealant).
Caution! Never use cement/concrete, etc...
The feeder cable MUST be twisted a minimum 10 times per meter & can be up to 100m long.
The loop must be placed at least 5m away from high tension cables and at least 1m away
from low tension cables. If the loop is placed in an area with reinforcing iron (typically a
concrete floor), the loop must be placed at least 50mm above the reinforcement.
If the detector is used for detecting high vehicles (lorries etc.) use only one loop for each
detector, otherwise it is possible to connect two loops to a single detector. Series coupling
the loops will give the largest sensitivity, parallel coupling gives the fastest reaction.
