1.4 Use of the product
Loop detector is primarily used to detect vehicles such as cars, trucks, buses and others.
A loop on the ground is required for the loop detector to detect any vehicles above the loop. The device
works on the same principle of an inductive sensor; utilizing the phenomenon of eddy current. When a
metal target/vehicle approaches on top of the loop, the magnetic field generated by the loop interacts with
the target and make the loop detector to change its status.
Loop detector can be used in carpark barriers, bollards, gates, toll gantries and many other door access
applications.

DIP-switch 1 - Selection mode: The loop detector operates on one out of four channels.
Depending on the noise sources in the vicinity (other loop detectors/frequency converters/starters
etc. i.e. crosstalk) can it be helpful to choose a channel where the loop detector is not disturbed by
the noise. The loop detector will indicate by a white flash which channel the loop detector are using
after power up.
Set DIP SWITCH 1 to OFF for automatically selection During startup will the loop detector
measure the noise levels on all channels and automatically select the channel with the least noise. This
will be done once every time the loop detector is powered up.
Set DIP SWITCH 1 to ON for manual selection Use dip switch 2 and 3 for selecting channel 1
,2 ,3 or 4.

Dip-switch 2 & 3 - Channel selection: Only used when dip switch 1 is set to “Manual”. Not
used if dip switch 1 is set to “Auto”.
Select the loop operating frequency by using the combination below:
(Switch 4) Delay: To prevent false and unintentional detections of objects moving nearby to the
loop, the loop turn on delay time can be prolonged to 2 seconds. This is to ensure a stable detection
before a valid detection signal is accepted. Default detection time is 0.1 second (100ms)
(Switch 5) ASB: In installation whereby there is high bed vehicles (i.e. trucks, lorry, tractors);
Automatic Sensing Boost (ASB) function can boost the loop sensitivity during detection. This ensures
high bed vehicles will be detected correctly. Using this switch 5, ASB can be turned on or off.
(Switch 6) Fail Mode: Selecting “Fail Safe” will ensure that during power loss to the loop detector,
the relay contacts will activate (energized) and hence resulting the barrier to open. This is preferred
in application whereby during power loss, it is preferred to open the barrier such as in public areas,
shopping malls etc.
While selecting “Fail Secure” will ensure that during power loss to the loop detector, the relay
contacts will remain deactivated (deenergized) and hence resulting the barrier to close. This is useful
in application whereby during power loss, it is preferred to close the barrier such as in private areas,
private apartments etc.
Note: The fail safe and fail secure mentioned above is only referring to the power loss to the loop
detector and not referring to the power loss of the main source or power loss to the barrier. This is
because power is still required for the barrier to open or close regardless. If the same power source
is used for loop detector and barrier, a kind of backup power is then required.
(Switch 7) (Switch 10) Out Mode: Relay output 1 and relay output 2 can be independently set
to be in pulse mode or presence mode.
In pulse mode, the relay only activates only for a short period when the vehicle enters or exits the loop.
In presence mode, the relay will remain activated as long as there is a vehicle parked on the loop.
Switch 7 is for relay 1 and switch 10 is for relay 2.
(Switch 8) (Switch 11) Time: If pulse mode is selected in switch 7 or switch 10, the pulse output
duration can be set to be 0.1 second or 0.5 second duration.
Switch 8 is for relay 1 and switch 11 is for relay 2.
(Switch 9) (Switch 12) Ent|Ext: If pulse mode is selected in switch 7 or switch 10, the pulse
output can set to be activated when vehicle enters the loop or only when the vehicle exits the loop.
Switch 9 is for relay 1 and switch 12 is for relay 2.
If presence mode is selected in switch 7 or switch 10, then switch 8/9 (relay 1) and switch 11/12
(relay 2) will change functionality.
In Presence mode, switch 8/9 (relay 1) and switch 11/12 (relay 2) are then used to set the maximum
time of an activation. If setting is different from infinite, the relay output will deactivate after the
specified time, following the table here:

7.2. Loop Installation
After determining the loop geometry, groove must be cut into the ground to install the loop. This can
be done by using a concrete cutting disc saw or similar device.
Clean the groove to make sure it is free of debris and free from moisture.
Place the wire along the groove and make sure it fitted tightly and nicely into the groove.
Measure the loop inductance using an inductance meter. Recommended value is between 80 to
300µH.
Seal the groove with any suitable epoxy or loop sealant found in the market.
Make sure when sealing the groove:
I. The temperature of the sealing compound does not exceed the temperature of the loop wire
insulation as this might melt the insulation and causes earth fault.
II. The loop wire must be totally fitted into the slot and not able to move after sealing.
III. The loop wire is placed nicely into the slot and no any section is exposed after sealing.
IV. The groove is clean and dry during sealing.

I. Mount the socket to the din rail in the cabinet.
II. Laid the feeder cable to the socket neatly and connect to the socket screw terminals according to
the wiring diagram. See section 3 of this manual.
III. Laid the power cable (24-240AC/DC) to the socket neatly and connect to the socket screw
terminals according to the wiring diagram. See section 3 of this manual. Do not turn on the power
switch yet.
IV. Connect other relevant devices to the 2 outputs of the loop detector accordingly and following the
wiring diagram. See section 3 of this manual.
V. Plug in the loop detector to the socket.
VI. Finish the other wiring of the relevant devices that are connected to the outputs of the loop detector.
7.4. Initialization Setup
I. Set the dip switch to the preferred functions required. See section 6 of this manual.
II. Make sure that there is no object/vehicle on top of the loop.
III. Turn on the power switch to the loop detector.
IV. The loop detector will automatically calibrate the loop inductance to optimal level.
V. The loop detector will also automatically tune the frequency of the loop. If manual frequency
tuning is preferred, it can be done manually via the dip switch.
VI. After loop detector has started, check that both loops indicate constant green on the loop LED
VII. Test the loop detector by activating the loop with an actual vehicle.
VIII. If the loop detector is found to be not reacting optimally, the sensitivity can be
adjusted manually using the front potentiometer for that specific loop. Look at the
loop state LED at the front of the loop detector to ascertain the loop is working fine.
It is recommended to always start with a low sensitivity i.e. sensitivity level 5.
Then test the response of the loop and slowly tuned up the sensitivity accordingly and only when
necessary.
IX. If required, adjust the dip switch for other setting such as the 2 relay outputs functions, ASB,
directional logic etc. accordingly. See section 6 of this manual.
Attention: Remember to press the reset button after changing the dip switch.
