Configuration from ToF (Time of Flight) tool
In order to access NMT 538 parameters directly through ToF (Time of Fight) tool, least below listed
items are required.
1. NMT 538 DD (Device Description) for ToF tool.
2. E+H HART modem with 232C connector
3. ToF installed computer (Do not use conventional Lap Top computer at hazardous are. Be sure
to use intrinsically safe computer if on site configuration is required.)
7.1 NMT 538 DD installation in ToF tool environment
1. Within the NMT 538 DD CD package, copy entire "NMT538_V010200_HART" folder into ToF Tool
; Dev DB folder.
2. Open "NMT538_V010200_HART" folder and select "enu".
3. Within "enu" folder, Right click on "NMT538_dd.enu.dll", and click on "Resister COM Server".
4. Installation of NMT 538 DD will automatically start, then click "Yes" to finish installation.
7.2 NMT 538 Configuration on ToF tool
Note!
Hook up the E+H HART modem in the NMT 538 connected HART loop prior to ToF tool activation
on your computer.
In case the host gauge to be the NRF 590 Tank Side Monitor, set "HART SCANNER" menu to
"DISABLE" on NRF 590. Due to the characteristic of multi drop HART loop, presence of two HART
master devices may cause configuration problem.
7.2.1
ToF tool activation
Start up the ToF tool and select "SCAN-BUS" to seek available HART device on the loop. Since
NMT 538 has no own operational power supply, it has to be connected NMS 53x Proservo or NRF
590 Tank Side Monitor to provide proper operation DC voltage.
Once the NMT 538 is recognized on the HART loop, device list on the bottom of the screen should
indicate the presence of NMT 538. Then double click on the NMT 538.
7.2.2
NMT 538 DD structure
NMT 538 DD is structured in 4 separate groups.
Temperature: data display only
All of parameters are display only. Reading of various temperature related data form the NMT 538.
NMT Set Data: data display & parameter configuration
Most of these parameters are named and positioned based on the Proservo NMS"s matrix
numbers. Please refer to the section 5.6.1 "Setting Parameter on the Matrix and section 5.6.1
"Additional Parameter Setting".
NMT Device Data: device data display
Most of parameters are display of NMT’s own device information except "tag no." and "assembly
number". These two are the only parameters you can configure in this group.
Position: data display & parameter configuration
Display of element position from element 1 to 10. If "Even Interval" is chosen and "Bottom Element
Position" is configured in NMT Set Data group, no parameter set would be necessary. If "Uneven
Interval" is chosen, this is the group to set element position (only element 1 to 10).
Note!
You have to go back to NMT Set Data and select "Calibration Select" to choose element number
and "Position X" to enter element position for element 11 to 16 (1 to 10 can be configured same
way in this method).
7.3 NMT 538 default value
NMT 538 is configured in most common parameters at factory set up. Normally you do not have
to set all of parameters. Please refer to the ToF tool instruction within the screen. Common
parameters are,
Bottom Element Position: 500mm
Element Interval: equal
Number of Element: 16 elements
Please refer to the section 5.1.7 "Additional Parameter Setting" to confirm rest of default value.
