Overview

Level monitoring and visualisation via touch panel

- Standardized system up to 15 silos

- Visualisation and operation via 7" touch panel (coloured, 800 x 480 pixel)

- Software language german or english

- Password protected

- Data in percentage, height, volume or weight

- Trend display, data storage

- Evaluation of the analogue 4-20 mA signals of any sensors, as well as Modbus RTU of the UWT-systems

- Different input signals within the same system is possible

- Implementation of full detectors

- Fill control via full alarm signal (Buzzer)

NT 4600 Basis unit

The heart of the NT 4600 is a touch panel, which runs

the visualisation software. All ll level control and display

functions can be operated via the touch panel. Access is

password protected. The electromechanical lead system can

be started by the visualisation software.

Integration of full detector

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

- For connection of 4-20 mA/ 2-wire sensors and full detectors

- On each converter up to 4 sensors and 4 full detectors can

be connected

- Provided for mounting directly on the silo

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:
