Configuring NMT81 with NMS5/NMS7/NRF590
Before connecting the NMT81 device physically to NMS5/NMS7/NRF590, make sure
that the compatibility mode is switched on. This ensures that the HART master will
recognize the device. Operation of NMT81 in compatibility mode is limited.
• NRF590: Connect the loop-powered local HART communication cable from NRF590
(intrinsically safe side compartment) to NMT81. NRF590 has been designed to
recognize NMT81 as a specific EHauser local HART device.
• NMS5/NMS7: HART master of the NMS5 and NMS7 is designed to recognize NMT81 as
HART device. Terminals 24 and 25 of NMS5/NMS7 and NMT81 are connected with a
local HART cable.
7.6.1
HART scanner of NRF590
Once NMT81 and NRF590 have been wired together, all HART devices will be scanned
automatically when NRF590 is turned on, however not all NRF590 are fully compatible for
recognizing NMT81. Contact your EHauser Sales Center for information on
NRF590 software and hardware version compatibility.
7.6.2
Parameters of NMS5/NMS7/NRF590
The configuration of NMT81 parameters displayed on devices depends on the installed
software and hardware versions of their devices. For further assistance, contact your
EHauser Sales Center.

Configuring NMT81 with NMS8x/NMR8x/NRF81
HART master of the NMS8x, NMR8x and NRF81 is designed to recognize NMT81 as HART
device. Terminals E1 and E2 of NMR8x, NRF81 and NMS8x are connected to NMT81 with
a local HART cable.

Preparation for configuring NMS8x/NMR8x/NRF81
Setting procedure
This procedure is only available for the DTM corresponding to FW 1.05 or later.
1. From the Expert menu, choose
Input/Output → HART device → HART device(s) →
NMT device configuration
.
2. Select
"Yes"
for
Config. device?
3. Enter the distance between the end of water bottom probe and the 0 mm level point
(reference datum plate) in the tank.
This completes the setting procedure.
