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.
