Prothermo NMT532 Operation
Hauser 53
8.3.6 Advanced temperature: VH50-VH59
Code Display Details
VH53 Element Point
(Element point) Item type Selection
Default 0
Selection 0-15 (Element No.1 = 0, Element No. 16 = 15)
Selects the number of elements for "Advanced" average temperature
calculations in VH26. The positions of the selected elements are
displayed in VH54 "Element Position," and additional volume factors
can be modified in VH55 "Element Volume."
VH54 Element Position
(Element position) Item type Read only
Range 0 to 99 999 mm
Displays the position of the element that was selected in VH53.
VH55 Element Volume
(Element volume) Item type Read only
Range 1 to 99 999.9
Sets the additional volume factor for the element that was selected in
VH53.
Additional volume can be added to individual elements for advanced
average temperature calculations (for details, see "VH26: Selec. Ave
Method").
8.3.7 Operation power adjustment: VH60 to VH69
Code Display Details
VH67 Common Voltage
(Common voltage) Item type Read only
Range 0 to 255 (0 to 3 V)
Displays the operating voltage of the temperature measurement line
(signal and common). Voltage across the common line (between 0 and
3 V) is converted into a range from 0 to 255.
VH68 Output Current
(Output current) Item type Read only
Range 0 to 65 535
Set as the output current according to specifications.
L
CAUTION
Changing the parameters:
The default value is adjusted at the time of shipping, and is determined
based on the device's specifications.
‣
Do not change the parameters as it will cause the device to
malfunction.
VH69 Ref Voltage
(Reference voltage) Item type Read / Write
Default 200
Range 0 to 255
Triggers a power supply failure alarm. In normal operating conditions,
this is activated via a HART communication loop at a supply voltage of
15 V
DC
or higher. If the consumed voltage decreases to 15 V
DC
or lower,
an error message is sent.
