Page 4: Basic Description
AfeTy All operations described in this instruction manual have to be carried out only by trained personnel or an accredited person. Warranty and post warranty service must be exclusively carried out by the manufacturer. Improper use, installation or set-up of the level meter can result in crashes in the applica- tion (overfilling of the tank or damage of system components). The manufacturer is not responsible for improper use, losses of work caused by either direct or indirect damage, and for expenses incurred during installation or use of the level meter. 1. B asic description The ARLM-70 „Amanda“ radar level meter works on the FMCW (frequency modulated con- tinuous wave) principle with a frequency of 25 GHz (K-Band). The level meter is equipped with a compact covered funnel antenna. The antenna cover prevents dirt, vapors and gases from entering the antenna. The ARLM-70 is intended for measuring the level of liquid and pasty substances. The level meter is two-wire with a current output of 4 ... 20 mA with HART communication. The measuring range is within 0.3 ... 20 m. 2. r ange of applications Non-contact radar level meters with an antenna are suitable for continuous level measu- rement at medium and longer distances, liquids and pasty substances.. They can be used both in various closed tanks, containers, in semi-open sumps, and in open space. Their use is suitable where their advantages are fully applied:... -

It is necessary to install the level meter so that Fig. 2: Level meter dead zone the bin level cannot interfere with the dead zone when filled up to the maximum. If the measured level interferes with the dead zone, the level meter will not work properly. d – Distance from the tank wall c – Maximum re- ach of the level meter - 20 m Fig. 3: Installation distance from the tank wall d > 1/12 c ARLM–70–20 (min. 200 mm) ARLM–70 © Dinel, s.r.o. - Page 7 Fig. 4: Possible installation of the installation neck • If the emitted radio waves of the level meter is affected by near objects (roughness on walls of the tank, various partitions, mixers etc.), it is necessary to map false reflections by activating the mode "TEACHING". In case of installed mixers, it is necessary to put the mixers to position under the level meter (direct the mixer paddle to the radio signal beam) (Fig. 5 and 6). Fig. 6: False echo from the mixer paddle Fig. 5: False echo from obstacles in the tank • Do not install the level meter in or above the filling point (Fig. 7).

- Page 8 Fig. 10: Intensely stirred surface radio signal. surface 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 radiation is inevitable, it is necessary to mount a shielding cover above the level meter(Fig. 11). • It is suitable to run the cable under a cable bushing (obliquely down in slack) according to Fig. 12 to prevent penetration of humidity. Then the rain and condensing water can flow off freely. • The cable bushing and connector have to be sufficiently tightened to prevent penetra- tion of humidity.

If in the bottom of the display appears (when entering the values) the i nscription "OUT OF LIMITS", the value specified for the item "DISTANCE TO LEVEL" is outside the measuring range of the level meter. If the inscription "SPAN TOO SMALL" is shown, it must be specified a larger span between MIN and MAX values. For more information, see chapter "Specifications". The decimal point position of the item 'LEVEL' is firmly set (according to the selected units). 1. Press the button to enter the menu and select "BASIC SETTINGS". Then use and to select "LEVEL". 2. The item "LEVEL" will now appear. Press and to enter the distance of the level meter to the MIN level and to the MAX level. 3. Press the button to save the data. Exit the menu by pressing the button. The level meter will return to measuring mode. © Dinel, s.r.o. ARLM–70... - Page 14 F A C T O R Y D E F A U L T D O N E R U N N I N G P R E S S E S C T O E X I T 1.

The MIN and MAX values e ntered in the LEVEL item are assigned the MIN and MAX limit values i n this DISPLAY item. By default, the level meter is preset so that the displayed value of 0% (resp. 100%) is assigned to the value of the distance from the minimum (resp. maximum) level. © Dinel, s.r.o. ARLM–70...

After activating the password the data may be read, but can not be edited. If you try to edit the settings (without true pass- word) the display shows "NO PASSWORD". The password can be any 5-digit numeric combination. The combination of numbers 00000 is reserved for disabling the password. Use the buttons in the menu "PASSWORD" to select the mode "ENTER" for en- tering the password or the mode "CHANGE" for changing the password (when activated, the words are displayed inversely). Press the button once again to confirm the selec- tion. You can change the password only when the level meter is unlocked. Otherwise, the words "NO PASSWORD" will be displayed. © Dinel, s.r.o.
