2.4 Rotating the display module
In order to facilitate operation and reading of the measuring value, the display module can be
rotated in the following way:
#Warning!
Danger from elctrical schock! Switch off power supply before opening the housing.
1. Using a 3 mm (7/64") Allen wrench,
losen the safety pin for the display
lid.
2. Unscrew the display lid.
Note!
If the display is difficult to
unscrew, unplug one of the
cables from the cable gland to
allow air to enter the housing.
Then, attempt once again to
unscrew the display lid.
3. Push in the two flat areas on each
side of the display module. Remove
the Module from the holder, rotate
it into the desired position and put it
back onto the holder. Snap-in
positions are located at an angle of
45° from each other.
#Warning!
The maximum angle of rotation is
180° in both directions (measured
from the initial position).
4. Replace the display lid on the Tank
Side Monitor housing.
Note!
Make sure to clean the threads
of the lid to remove any dust or
particles. Check that O-ring is in
place and reapply anti-seize
grease.
5. Adjust the safety pin so it is set over
the display lid and tighten.

2.5 Grounding
The NRF590 must be grounded to the tank potential before communication and power
connections are made. The connections (A 4mm2) from each outer ground plug of the NRF590
to the tank ground must be made before any other wiring connections are made. All grounding
must be compliant with local and company regulations and checked before the equipment is
commissioned.

EIA-485 Modbus
The NRF590 protocol uses a shielded 3-wire EIA-485 hardware interface to communicate with
the modbus master. EIA-485 is a high speed, differential communications network that allows
up to 32 instruments to operate on one network.
• Using one shielded twisted pair of 18 AWG (0.75mm2) wire, connect the EIA-485 at terminal
9 and 10.
• Termination of the EIA-485 bus at the NRF590 can be set in the operating menu (only enable
on end instrument in a loop).
• Connect the 3rd wire from the control system signal common (0V) to terminal 11 or 12.
• Max distance: 1300 m (4265 ft).
Whessomatic WM550
The WM550 protocol provides 2 wire, current loop communication and allows up to 16
instruments per loop. For redundancy (safety function) two wire pairs are used. They always
transmit the same values. The WM550-loops connect to terminals 9 - 10 and 14 - 15.
Max. distance: 7000 m (22967 ft).
BPM
The BPM protocol provides 2 wire communication allowing up to 10 instruments to operate on
a loop. BPM connects to terminals 9-10.
Max. distance: 1000 m (3281 ft).
Mark / Space
For a NRF590 using the Mark/Space field communications option, the following additional
wiring connections must be made:
• Run 2 twisted pairs (one power, one communication) of 18 AWG (0.75 mm2) wire
(Mark/Space wires) into the upper terminal compartment through one of the conduit entries
along with the 48 Vdc power wiring.
• Connect the Mark line to terminal 10 and the Space line to terminal 9.
• Connect to power supply at terminals 8 and 11.
L&J Tankway
Including power and ground, L&J is a 4-wire system, allowing 50+ instruments to be connected
on the communication bus. L&J connects to terminals 8 through 11.
GPE
The GPE protocol provides 2 wire current loop communication. GPE connects to terminal 9-10.

Tank Side Monitor NRF590 Wiring
Endress+Hauser 17
3.1.4 Grounding of the fieldbus screen
The screen of the fieldbus cable should be connected to ground at both ends. If this is not
possible due to signal disruption by potential equalisation currents, it is advisable to connect the
screen of the fieldbus cable to terminal "00 S" at the NRF590 and to ground at the other end. The
"00S" terminal provides a 500V capacitor between the cable screen and tank ground potential.
3.1.5 Connection of the auxiliary energy
The Tank Side Monitor can be AC or DC supplied, depending on the installed power supply
board. The AC supply needs to be connected to the terminals marked L/+ (Line) and N/-
(Neutral), corresponding with the phase/line and neutral wire. DC supply can be connected to
the same terminals, for which it is necessary to connect the positive (+) to the terminal marked
(L/+), and the negative to the terminal marked (N/-).
Note!
When using the public power supply, install an easy accessible power switch in the proximity
of the device. Mark the power switch as a disconnector for the device (IEC/EN 61010).
3.1.6 Connection of the non-i.s. 4 to 20 mA analogue input
Depending on the selected fieldbus communication board, a non-i.s. self-powered or loop
powered analogue transmitter can be connected. The analogue signal for the loop powered
transmitter can be connected to the terminals 14 (-) and 15 (+24 Vdc). The maximum supply
current for the analogue transmitter is limited to 24 mA. The analog signal for a self powered
transmitter should be connected to terminals 11 or 12 and 14.
L00-NRF590-04-00-08-en-019
3.1.7 Connection of the non-i.s. 4 to 20mA analogue output
For all field communication boards except the Modbus Option without analog in/output, a
non-i.s. 4 to 20mA output is available. Via Software settings, this analogue output can be
connected to any parameter in the Tank Side Monitor. The analogue output is available between
terminals 13 (+) and 12 (-). From SW 02.01.xx onwards, an additional HART signal is available
at terminal 13.

3.1.8 Connection of the secondary non-i.s. 4 to 20 mA analogue output
For the V1, WM550 and GPE field protocol, a secondary analogue output is available at the
terminals 8 (+) and 11 (0V). This output can also be used to power a FMR5xx radar.
3.1.9 Connection of the discrete in and output
The Tank Side Monitor can be equipped with up to 2 discrete I/O modules. These modules can
be used for interfacing to non-i.s. discrete in- or outputs. Input and output voltage and current
ranges depend on the type of selected module installed in the relevant I/O slot. Terminals 4 and
5 correspond to discrete I/O slot A, terminals 6 and 7 correspond to discrete I/O slot B. For
details on available I/O modules see Operating Instruction BA00256F/00/EN on CD-ROM.
L00-NRF590-04-00-08-en-004
Note! 250VAC is the maximum load that can be connected.
3.1.10 Connection of a Proservo NMS5 to the non-i.s. HART input
It is possible to connect Proservo NMS5 to the Tank Side Monitor NRF590 using the non-i.s.
HART input available in the Exd terminal compartment.
Note!
• This is only possible if the NMS5 is equipped with a HART digital output (passive).
The relevant order code must be: NMS5 - ***H********. ("H" meaning "HART passive").
•TheSoftwareVersionmust be: 04.24 or later.
• The Hardware Version must be: 4.00 or later.
• The Tank Side Monitor NRF590 software version must be V02.04 or later
The communication is "read only". This type of connection does not provide any parametrization
or commanding capability from the Tank Side Monitor NRF590 to the Proservo NMS5.
