Page 5: Installation Instructions
NSTALLATION INSTRUCTIONS • Install the level meter in the vertical position into the upper lid of the tank or reservoir using a welding fl ange, a fastening nut or a fl ange so that the level meter axis can be perpendicular to the surface level of the measured liquid (Fig. - Page 6 • During fi lling, mixing and other processes, foam can arise on the surface level of the measured liquid. The thick foam considerably absorbs the ultrasonic signal which might cause malfunction of the level meter (Fig. 5). For such cases, it is necessary to set up "SENSITIVITY"...
- Page 7 • The level meter must not be installed in places with direct solar radiation and must be protected against weather effects. • If the installation in places with direct solar ra- diation is inevitable, it is necessary to mount a shielding cover above the level meter. •...

PERATION Set the level meter using 3 buttons placed on the display module (see Chapter Set-up elements). After 5 min. of inactivity, the level meter automatically returns back to the measurement mode. If the password is active, the level meter will be also locked. The values that have not been confi... - Page 11 1. Fill up the tank up to the required level. 2. Press the button [ OK ] to access the basic menu. Use the same button to select the item "BASIC ADJUSTMENT" and then use [↑ ↓] and [ OK ] to select the item “AUTO MAX”. 3.

The function can be used to suppress devia- tions of the displayed values in case of quick or step changes of the level (e.g. stirred surface). The response time of the subsequent measurement will be longer and the level meter will react to quick changes with a defi...

Page 13: Advanced Settings
DVANCED SETTINGS In the supplemented confi guration, you can set parameters of sensitivity, mapping of false refl ections, temperature difference compensation, behaviour in case of fault conditions or HART communication. Here, you can set the sensor into the initial state or reset it as well. - Page 14 Mapping of false refl ections lasts 5...30 sec. according to the level meter type. In case of installed mixers, it is necessary to position the mixers under the level me- obstacles ter (direct the mixer blade to the ultrasonic signal beam). Note: If there are signifi...
