1. Average Temperature Prothermo NMT539 Installation on Tank Top

• The actual installation may require an installer to work in a hazardous area. Safety must be taken into account in order to avoid any

harmful conditions.

• The installation method depends on the type of NMT539. Refer to BA01025G/08/EN "Installation Instructions."

2. Wiring to Host Instruments (Tank Side Monitor NRF590 or Proservo NMS5/NMS7)

• Wiring material and conditions must be in accordance with intrinsically safe standards.

• One end (normally on the host instrument side) of the shield twisted pair of cables must be grounded at the terminal connection.

• Refer to BA01025G/08/EN "Installation Instructions."

3. NMT539 Initial Setup

• Both NMT539’s own device setting and local HART setting to the host instrument must be performed.

4. Data Flow from NMT539 to Host Instruments

• Individual element temperature data: Individual raw element temperature can be accessed regardless of liquid level information on

the NMT539’s data matrix.

• Average temperature data: The host instrument sends liquid level data on the local HART line to NMT539. NMT539 calculates both

Gas and Liquid phase average temperature based on this given liquid level.

• WB (Water Bottom) data: WB data and information are continuously scanned and transmitted by host instruments as long as the local

HART connection is active.

2 Initial Set Up

2.1 Local HART Connection

2.1.1 Endress+Hauser Tank Gauging Instrument

NMT539 is developed and designated primarily to work with Endress+Hauser tank gauging host

instruments Tank Side Monitor NRF590 or Proservo NMS5/NMS7.

Both temperature and / or water bottom information are transmitted on a two wire i.s local HART loop

to the host instrument. Since both NRF590 and NMS5/NMS7 have a pre-configured menu for NMT

series functionality as default, simple wiring to NMT539 will complete the initial setup for NMT539.

• Refer to the Installation manual BA01025G/08/EN for NMT539 physical installation procedure

prior to start up.

• The availability of each of the four parameters can vary depending on the selected NMT539 mea-

surement function on the product code.

2.2 Device Setup: NRF590

Connect the loop powered local HART communication cable from the NRF590 (intrinsically safe side

compartment) to NMT539 according to BA01025G "Installation Instructions."

Since NRF590 has been designed to recognize NMT539 as a specific Endress+Hauser local HART

instrument, set up is easy.

2.2.1 HART Scanner

After the physical cabling between NMT539 and NRF590 is complete, scan all connected loop powered

local HART devices by activating "HART SCAN" on NRF590.

Not all NRF590 have fully accessible compatibility to recognize the NMT539. Consult with

Endress+Hauser representatives to cross check the software and hardware version of NRF590.

2.2.2 NMT539 Specific Parameter Setup on NRF590

• Configuration of NMT539 parameters on the display of NRF590 is dependent on the installed soft-

ware and hardware version of NRF590. Refer to the operating manual of NRF590 to determine

accessible parameters.

• All required initial setup and configuration can be performed by FieldCare. Detailed information will

be described in the following operation related chapters.

2.3 Device Setup: NMS5/NMS7

NMS5/7 is also specifically designed to recognize NMT539.

Terminals 24 and 25 of NMT539 and NMS5/NMS7 are connected by using local HART.

The connection between NMS5/NMS7 and NMT539 is specified by Ex approval.

Refer to the separate BA01025G "4.4 Terminal Connection" for wiring.

2.3.1 Preparation of NMS5/NMS7

MS5/NMS7 must be pre-configured to accept the NMT539 connection via the multi drop local HART

loop.

GVH362: NMT Connection

"Average Temp." must be selected in order to configure NMT539.

To change this parameter, an access code is required. Refer to BA00401G "NMS5 Operation Instruc-

tions" for further information.

2.3.2 NMT539 Configuration on NMS5/NMS7

Most required NMT539 parameters can be configured on G4 "Temperature" matrix as it is on the dis-

play of NMS5/NMS7.

WB (Water Bottom) sensor information is not available on NMS5/NMS7 before ROM version 4.24.

Consult with Endress+Hauser representatives to update the installed NMS5/NMS7 function.

Typical NMT539 parameters are displayed on the matrix of NMS5/NMS7

3 Operation and Description of Instrument

Function

This section is described for description for FieldCare.

NMT539 has segmented local HART device code depending on measurement function. Following 4

local HART device codes are normally pre-set at the factory by jumper setting.

Do not change jumper setting by disassembling NMT539’s internal module. It may cause major mal-

function due to distorted precise factory calibration.

3.1 Local HART Device Designation

Local HART device code "184":

This code is the device code for temperature measurement function only. This 184 is specifically

designed for NMT539 converter only version and converter + temperature version. No WB sensor is

available with code 184.

Local HART device code "185":

This code is the device code for equipped NMT539 water I/F measurement function. FieldCare does

not recognize code 185.

Local HART device code "186":

This code is the device code for fully equipped NMT539. NMT539 with converter + temperature +

water bottom uses code 186.

3.2 Device Data

Tag Number: read and write

Default: local HART

This number is for A customer specific device identification and control number (or name). Tank name,

site number, or any other ID can be entered.

Assembly Number: read and write
