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 configuration of Nivobob NB 3000 and NR 3000 radar
as well as implementation of full detectors:
