7.1 Local HART connection
7.1.1 Hauser tank gauging instrument
NMT532 is developed and designated primarily to work with Hauser tank
gauging host instruments NRF590, NMS5, NMS8x, NMR8x, or NRF81. Temperature
information is transmitted on a two wire intrinsically safe local HART loop to the host
instrument. Since NRF590, NMS5, NMS8x, NMR8x, and NRF81 have a pre-configured
menu for NMT series functionality as default, simple wiring to NMT532 will complete the
initial setup for NMT532.
The parameters listed in this document are parameters that can be checked when the
instruments are connected to NMT532 with FieldCare. Since the parameters that can
be checked from the HMI of the connected HART Master, such as NMS8x and NMS5,
differ depending on which HART Master is being used, refer to the respective
operating instructions.
7.1.2 Measuring functions
Temperature measurement
0 Converter only
1 Tempe converter
These four types of basic data are available as standard.
• Average liquid temperature
• Average gas temperature
• Level (VH02 measured distance)
• Device status
7.2 Device configuration: NRF590
Connect the loop-powered local HART communication cable from NRF590 (intrinsically
safe side compartment) to NMT532. NRF590 has been designed to recognize NMT532 as
a specific Hauser local HART device.
7.2.1 HART scanner
Once NMT532 and NRF590 have been wired together, all HART devices will be scanned
automatically when NRF590 is turned on.
Not all NRF590 are fully compatible for recognizing NMT532. Contact your Endress
+Hauser Sales Center for information on NRF590 software and hardware version
compatibility.
7.2.2 NMT532 specific parameter setup for NRF590
The configuration of NMT532 parameters displayed on NRF590 depends on the installed
software and hardware versions of NRF590. Refer to the NRF590 operating manual to
determine accessible parameters. All default settings and parameter configurations can be
carried out using FieldCare. Detailed information will be provided in the following sections.
