Work Status Indication Power Indicator :
It stays on during working hours. Detection Indicator: After the power is on, the detector will calibrate automatically for about 3 seconds. During calibration, the green indicator will always be on.
ចំណាំ៖ There should be no vehicles on the loop during calibration.) After the calibration is completed, the green indicator will go out. (The green indicator goes out when there is no car; stays on when there is a car; continues to flash when the vehicle detector is abnormal.

The user can change the frequency of the loop to avoid crosstalk from adjacent loops or ambient frequencies. The detector provides four frequency options, which can be set by the DIPI and DIP2 on the panel.
- ការកែតម្រូវភាពរសើប
The user can change the sensitivity by using the DIP3 and DIP4 on the panel, with 4 levels. When debugging, first set the sensitivity to a lower level. If there is no output, increase the sensitivity by one level. Repeat this process until the vehicle detector works normally and stably.

Automatic Sensitivity Boost is selected by DIP5 on the panel. OFF – Disabled, ON — Enabled. - របៀបតម្រង
When the environmental electromagnetic disturbance is large and causes a malfunction, you can pull DIP6 to ON to increase the filter coefficient to filter out the disturbance. In filter mode, the reaction time of the detector is delayed, and the sensitivity will be reduced. Usually, the filter mode is disabled by setting the DIP6 to “OFF”.
ការយកចិត្តទុកដាក់
If the detector doesn’t work normally, please check the loop, whether the embedding is correct, whether the feeder is twisted or damaged, then adjust the operating frequency and sensitivity level, and finally use the enhanced filter mode.

Loop and Feeder Specification
The loop must consist of insulated wire with a minimum copper cross-sectional area equivalent to 1.5 square millimeters. The feeder should be of the same material, but twisted, with a minimum of 20 twists per meter.
- Joints in the loop or feeder are not recommended. Where this is not possible, joints are to be soldered and terminated in a waterproof junction box. This is extremely important for reliable detector performance.
- Where long loop feeders are used, or feeders are rout together with other electrical wiring, the use of a screened cable is suggested for the feeder. The screen must be earthed at the detector end only.
Sensing Loop Geometry
Sensing loops should, unless site conditions prohibit, be rectangular in shape and should normally be installed with the longest sides at right angles to the direction of traffic movement. These sides should ideally be 3 feet apart. The length of the loop will be determined by the width of the roadway to be monitored. The loop should reach to within 1 foot of each edge of the roadway. In general, loops having a circumference measurement in excess of 30 feet should be installed using 2 turns of wire, while loops of less than 30 feet in circumference should have three or more turns. Loops with a circumference measurement of less than 18 feet should have four turns. It is good practice at the time of installation to construct adjacent loops with alternate three and four-turn windings to minimize crosstalk.
ការដំឡើងរង្វិលជុំ
All permanent loops should be installed in the roadway by cutting slots with a masonry cutting disc or similar device. A 450 crosscut should be made across the loop corners to reduce the chance of damage that can be caused to the loop cable at right-angle corners. A slot must also be cut from the loop circumference at one corner of the loop to the roadway edge to accommodate the feeder. Please refer to the loop documentation for the slot width and depth. A continuous loop and feeder is obtained by leaving a tail long enough to reach the detector before inserting the cable into the loop slot. Once the required number of turns of wire is wound into the slot arou nd the loop circumference, the wire is routed again via the feeder slot to the roadway edge. A similar length is allowed to reach the detector, a nd these two free ends are twisted together to ensure they remain in proximity to one another. (Minimum 10 turns per foot). The maximum recommended loop feeder length is 300 feet. It should be noted that the loop sensitivity decreases as the feeder length increases, so ideally, the feeder cable should be kept as short as possible. The loops are seated using a “quick-set” black epoxy compound or hot bitumen mastic to blend with the roadway surface
សំណួរគេសួរញឹកញាប់
What is the Atu Tech ACM706 Single Loop Vehicle Detector and how does it work?
The ACM706 is a vehicle detection device that uses an inductive loop installed under pavement to sense the presence of vehicles. When a vehicle passes over or stops above the loop, the metal chassis changes the loop’s electrical properties, and the detector outputs a signal indicating a vehicle is present. This basic principle is common for single‑loop vehicle detectors used in parking lots, gate controls, and access systems.
Where can I install this vehicle detector?
This type of detector is typically installed with an inductive loop buried in the ground at entry/exit points of parking gates, barrier systems, or access control installations. The loop wiring connects to the detector unit, and the detector then provides a relay output that can trigger gates, lights, or control systems when a vehicle is detected.
What kind of maintenance or settings should I know about?
After installation, you can usually adjust the sensitivity settings so the detector reliably senses different vehicle sizes. Regular checks on the loop wiring and detector power help ensure stable performance. Some detectors also offer automatic tuning and environmental compensation to maintain accuracy despite temperature or weather changes.
