Type 2298 80 GHz Radar Level Sensor
4.3.5
Commissioning and setting up
When the device is connected correctly, the radar starts up with a current consumption of 3.5 mA after switching on the power sup-
ply. After 3...5 s, the ECHO and the COM LED light up together. After another 5...10 s, the transmitted current corresponding to the
operating mode appears on the current output. In this case, the device measures with factory settings. The factory default settings
are suitable for checking functionality and using the device for simple measurement tasks, but the device's full potential can only be
used with the correct programming tailored to the requirements of the measured process. Therefore, to get to know the operational
characteristics thoroughly and solve complex measuring tasks, it is necessary to study the chapters about programming.

ON, if the device receives a suitable echo.
BLINKS when the device is searching for an echo.
FLASHES UP ONCE if there has been a HART message exchange,
ON, if the device is in remote programming mode.
BLINKS for 4 seconds after the device is switched on: service
communication connection can be established during this time. If it
continues to blink, it indicates a firmware error.
ON, when CC-C2 is energized.
OFF, when CC-C1 is energized.
All parameters of the device have a factory default value, which
can be restored later if necessary.
The factory settings of the type 2298 level measuring device are
as follows.
Measurement mode: level (LEV).
•
Zero level is assigned to the maximum measuring distance.
•
The current loop output is directly proportional to the level.
•
4 mA and 0% are assigned to zero level.
•
20 mA and 100% are assigned to the maximum level (mini-
•
mum measuring distance).
The current loop output holds the last value in case of an
•
error.
Level-following time constant: 10 s.
