incl. alarm "silo full"
- Buzzer with reset button (supplied loose,
for outdoor mounting)
- One unit for all connected silos
- Alarm happens, if one of the silos gets full
- Reset of the alarm
- Provided for mounting directly on the silo
Modbus converter

Electrical installation
Handling In case of improper handling or handling malpractice, the electric safety of the device cannot be
guaranteed.
Installation regulations The local regulations or VDE 0100 (Regulations of German Electrotechnical Engineers) must be
observed.
Fuse Use a fuse as stated in the connection diagrams.
RCCB protection In case of a fault, the supply voltage must be automatically switched off by a RCCB protection switch
to protect against indirect contact with dangerous voltages.
Power supply switch A voltage disconnection switch must be provided near the device.
Wiring diagram The electrical connections are made in accordance with the wiring diagram.
Supply voltage Compare the supply voltage applied with the specications given on the name plate before switching
the device on.
Cable gland Make sure that the screwed cable gland safely seals the cable and that it is tight (danger of water
intrusion).
Cable glands that are not used have to be sealed with a blanking element.
Field wiring cables All eld wirings must have insulation suitable for at least 250 V AC. The temperature rating must be at
least 80°C (176°F).
Installation in Hazardous
Locations
The NT 4500 and the Mobus converter are not permitted for installation in Hazardous Areas. Observe
the valid regulations for wiring in Hazardous Areas, if the NB 3000/ NB 4000 is installed in Hazardous
Areas.

Commissioning
2. Check the wiring
Make sure that the Modbus network is wired, set the Modbus Termination Resistor (and for NB 3000 the Biasing), check that the
Ethernet connection is available (see "Electrical installation" from page 5 onwards).
3. Perform the basic settings for the visualisation
• Basic Settings - User (see page 13).
To do further settings, the userlevel must be set to Level 2.
• Basic Settings - System (see page 14).
4. Perform the settings of the silo data and of the connected sensors
With the following settings, the connected sensors are addressed via the visualisation and give a real measurement result. For this
settings the above mentioned synoptical table is helpful:
• Silo Settings (see page 16).
• Sensor Settings (see page 17 - 18).
Note: All units are presetted to 19200 Baud. Thus no setting is required.
1. Generation of a synoptical table
Commissioning is facilitated if an overview of the connected sensors is made in advance.
The table shows an example of a project with 10 silos and mixed conguration of Nivobob NB 3000 and NR 3000 radar
as well as implementation of full detectors:

screen are started as well.
While the measurement is running, a green arrow appears in each silo.
In the top line the date and time of the last measurement is displayed.
Measurement start is not possible due to one of the following reasons:
Under "Sensor-settings" the selection"Sensor Nivobob" is not present (see page17).
The "Modbus for silo" is set to "inactiv" (see page 17).
Display "Blocked Start": The Nivobob Measurement Start is set to "no" (see page 17).
Display "Blocked 24 - 26": The bridge between terminal 24 - 26 at the Nivobob ist open. See Nivobob user manual.
Horn reset
Reset of the full signal (horn). The button appears only, if the horn is activated.
Possible other messages:
"Ofine": The "Modbus for silo" is set to "inactiv", thus the respective silo has no valid measurement (see page 17).
"Modbus": The Modbus network is not working. See items under commissioning (page 10).
Further diagnostic messages may appear. If so, the messages implement comments for reason and possible measures.

Setting to "Nivobob".
Input Signal
Modbus for silo:
It is possible to switch off single silos from the Modbus network (e.g. for revision) by setting the related Modbus ID inactive. If so, the
other silos stay active. Inside the related silo it will be stated "Ofine".
Modbus ID:
Input of the Modbus ID (Modbus adress) of the Nivobob.
The Modbus address of the Nivobob is setted in the Nivobob communication menu (see user manual of Nivobob). It is reasonable to use
the address 1 for the rst device, then ascending to 2, 3, etc. With mixed use of Modbus converters the rst addresses of the Modbus
converters are already preset (see next page), the Nivobob addresses must then be allocated above these. Optional (with selection code
33) the Nivobob devices are delivered with already preset address.
Full detector
If a full detector is connected, it is read with setting to "Modbus" (see electrical installation page 7 for connection to NB 3000/ NB 4000).
If "value" is selected, the message for full detection is activated, if the entered value (in percent) is exceeded by the material level.
Nivobob
Enable start:
Measurement start can be blocked by setting to "no", for example while a silo is beeing lled. Inside the related silo it will be stated
"Blocked Start".
Max. move distance:
Setting of the max. move distance of the sensor weight.
By pressing "read" the value is readout from the Nivobob and displayed.
By setting a value and pressing "write" the setted value is written into the Nivobob.
Note: The setting of the max. move distance can also be done directly at the Nivobob.
Note: Further settings inside the Nivobob menue are not relevant, since the visualisation requires only the measured distance from the
Nivobob and calculates to a volume based display.

It is possible to switch off single silos from the Modbus network (e.g. for revision) by setting the related Modbus ID inactive. If so, the
other silos stay active. Inside the related silo it will be stated "Ofine".
Modbus ID:
Input of the Modbus ID (Modbus adress) of the Modbus converter.
The Modbus converters are factory presetted to address 1 for the rst Modbus converter, then ascending to 2, 3, etc. The settings can
not be changed. A label with the Modbus address is present inside the Modbus converters on the implemented module M-7002.

Channel 3 is allocated to the terminal Vin3+ and DI3
Full detector
If a full detector is connected, it is read with setting to "Modbus" (see electrical installation page 9 for connection to Modbus converter).
If "value" is selected, the message for full detection is activated, if the entered value (in percent) is exceeded by the material level.
b) With use of 4-20 mA sensor (connected via Modbus converter)
Programming of the 4-20 mA sensor:
The connected sensor must be set as follows:
- 4 mA must correspond to the level value 0% (see "Silo settings", page 16).
- 20 mA must correspond to the level value 100%.
Note to NR 3000: H and L are related to the xing ange.
- The sensors needs to have a linear level signal (relation between the signal output and level in the silo). The volume-based calculation is
performed in the visualisation only.
