SENSOR OPERATION

GENERAL OPERATION

ATM220-UHD must be connected to a console computer via an interface to set up the device before use. Once the setting is complete, it works automatically in regular operation and requires no additional operator intervention.

General sensing data, measuring ranges, and video data can be shown as a graphical view by specific user interface software for ATM220-UHD. The software is also used for setting the sensor.

Please note that the user interface software cannot display every origin measured value data on a dashboard. It is primarily designed for monitoring purposes for the conditions of data sensing inflows and to check up on the settings.

POWER SWITCHING ON/OFF

ATM220-UHD does not have a specific power switch on the device, and it is turned on when an acceptable range of input power sources is permitted.

It is recommended to have an external power switch on the power distribution side in case the sensor is turned on and off occasionally.

Disconnect the device from the voltage supply to switch it off:
✔ The device switches off. The device configuration remains unchanged; sensing values are lost.
Connect the device to the voltage supply:
✔ The device starts with the last saved configuration data.

MOUNTING CONDITIONS

Mounting of ATM220-UHD sensor must be considered field conditions to escape the wrong measurement.

The best field condition of sensor mounting is when the sensor can be mounted in the Center of the detecting area without any obstacles.
Using each separated sensor for several different types (directions) of roads in the Center of each road is recommended.
Mounting the lean side of the road and sensing the road from the warped position is not recommended.
Sensing roads with obstacles such as traffic lights, traffic signs, and street trees is not recommended.
Sensing several different types (directions) of roads using only one sensor is not recommended.
