READ CAREFULLY BEFORE USE. KEEP IN A SAFE PLACE FOR LATER REFERENCE. This instruction manual is for the NivuLink Radar radar sensor and serves its intended use. This instruction manual is oriented exclusively to qualified expert personnel. Read this instruction manual carefully and completely prior to installation or connection since it contains relevant information on this product.
The radar sensor is designed to operate with up to eight batteries (Fig. 2-1 Pos. 1). The batteries can be purchased from specialised electrical retailers. However, only batteries approved by NIVUS are permitted (see Chap. "17 Specifications" and "37.1 Battery Replace- ment").
The NivuLink Radar is activated by holding the enclosed ring magnet ZUB0 NFM MAGNET (Fig. 2-2) on the side of the enclosure in the area of the status LED. Beyond that, the NivuLink Radar has no other control elements. The entire operation and pa- rameterisation is carried out via the NIVUS WebPortal.

Functional Description 19 Functional Principle of Data Acquisition/Transmission The NivuLink Radar is a compact radar sensor for determining and transmitting fill level data. The measurement data is transmitted wirelessly (LTE-M / NB-IoT or LoRaWAN) to the NIVUS WebPortal at a selectable interval.
The distance to the medium surface is determined from the signal transit time between the transmitted and received signal and the level is calculated from this. Fig. 20-1 Measurement via PCR (perpendicular, 90°) Page 24 NivuLink Radar – BA – Rev. 00 / 13.03.2024...
Instructions and the instructions for fastening sensors. Disregarding may result in interference with the measurements. NIVUS GmbH expressly point out that all permits and work regulations must be obtained or observed. The radar sensors used must be fixed permanently and reliably.
Photos/videos (smartphone quality is sufficient) of the planned measurement place • 22.2 Selecting the appropriate Sensor Type The NivuLink Radar sensor is available with two different antennas. Once the installation lo- cation has been determined, it is necessary to check which of the two antennas is best suited.
90° to the medium surface. Compliance with this angle is ensured when using the original NIVUS mounting accessories (see Chap. "24 Mounting and Fastening of the Radar Sensor"). If other brackets/mounting options are used, it is essential to ensure that this angle is set un- changeably.
Equipment damage due to water If you open the enclosure/battery compartment cover in the rain or in a location with poten- tial water ingress from above, be sure to protect the NivuLink Radar in a suitable manner against the ingress of moisture.
• Variant 4: For all NivuLink Radar sensors. Fastening on ceilings, holders etc. (G1″ thread). Without NIVUS mounting material. Basic condition: the NivuLink Radar sensor is mounted perpendicular / 90° to the me- dium surface (not shown). See also Chap. "24.1 Mounting Variants" and "38 Accessories".
Ensure that the LED status display is always visible when the radar sensor is in- stalled The current status of the radar sensor can be recognised by the flashing code on the sta- tus display. Page 30 NivuLink Radar – BA – Rev. 00 / 13.03.2024...

Open the gap between the upper (Pos. 2) and lower (Pos. 3) nut (G1″) so that the sensor can be pushed into the fastening angle (Pos. 1). Tighten both nuts to clamp the sensor (Pos. 4). NivuLink Radar – BA – Rev. 00 / 13.03.2024 Page 31...

This mounting variant can also be used with the channel bracket (with cross holder) if necessary (see also Chap. "38 Accessories"). Info: If the manhole is extremely deep, a special version with a long pipe can also be re- quested from NIVUS. Page 32 NivuLink Radar – BA – Rev. 00 / 13.03.2024...
Ex area. Procedure: 1. Open the NivuLink Radar enclosure according to Chap. "23 Opening / closing the en- closure / battery compartment cover of the radar sensor". The SIM card slot (Fig. 25-1 Pos. 1) is accessible.
Tools required to unscrew/screw the antenna (antenna version "A"): 2x open-end spanner SW29 for loosening/tightening the cable gland • • Special NIVUS SW8 spanner for loosening/tightening the antenna socket (Fig. 26-1) Fig. 26-1 Special NIVUS spanner SW8 Do not damage the antenna cable The antenna cable (Fig.

3. Slide the cable gland on the antenna cable (Fig. 26-2 Pos. 1) out of the way in the direction of the magnetic base antenna. 4. Position the special NIVUS spanner SW8 (Fig. 26-1 or Fig. 26-2 Pos. 4) on the thread of the SMA antenna connector (Fig. 26-2 Pos. 5), tilt it slightly backwards for better accessibility and unscrew the antenna connector.
Commissioning 27 Notes to the User Before connecting and operating the NivuLink Radar the instructions below shall be followed. This instruction manual contains all information required for parameterisation and use of the radar sensor. The instruction manual is intended for qualified expert personnel. The instruc- tion manual is intended for qualified expert personnel.
28.1 Status display/lighting system of the radar sensor The status LED (Fig. 28-1 Pos. 1) on the Top side of the NivuLink Radar lights up during op- eration according to a predefined system that allows conclusions to be drawn about the cur- rent status of the device.
LED light sequence. A firmware update can also be installed. Initial Start-Up/Activation Before the NivuLink Radar sensor can measure and transmit for the first time, it must be acti- vated once with the enclosed ring magnet (Fig. 2-2). To do this, hold the ring magnet near the status LED on the side of the upper flange of the sensor (Fig.
Page 39
Commissioning Shutdown/Deactivation If the NivuLink Radar sensor is not to be used for a longer period of time (transport, storage, etc.), it can also be deactivated/switched off using the magnet. This is done as described in Tab. 6 line 2.
Setting Parameters in NIVUS WebPortal 29 General Information on Parameterisation The entire operation and parameterisation of the NivuLink Radar is carried out via the NIVUS WebPortal. The basic requirement for working with the NivuLink radar sensor is access to the NIVUS WebPortal and basic knowledge of working with it.
In addition, there are various diagnostic process variables (Diag_xx), which are used exclusively for NIVUS customer service. In the event of problems, the customer service will refer back to it for troubleshooting/solving. These are displayed via the "Measurement Place Configuration"...

• In event mode, the measurements are taken according to the defined measurement interval and are transmitted immediately to the NIVUS WebPortal (regardless of the Heartbeat in normal mode). If the sensor falls below the threshold for event mode after 10 measurements in a row, it switches from event mode back to normal mode.
32 Adding/removing process variables or changing the name of the measurement place Adding/removing and changes in the NIVUS WebPortal Changes in the NIVUS WebPortal are made in accordance with the NIVUS WebPortal manual. Download pdf under "Help" in the NIVUS WebPortal.
4. Prepare the NivuLink Radar sensor for the firmware update using the ring magnet: - Hold the ring magnet to the NivuLink Radar sensor (on the rim in the area of the NivuLink Radar – BA – Rev. 00 / 13.03.2024...
