HART INPUT VALUE Prerequisite
The function is not available if OFF was selected in HART INPUT (ä 167).
Description
Use this function to display the value read in via HART INPUT.
If a gauge pressure is read in, it is converted to absolute pressure with the AMBIENT
PRESSURE (ä 168).
Display
5-digit floating-point number, including unit
Unit on the display depends on:
• UNIT TEMPERATURE (ä 102)
• UNIT DENSITY (ä 104)
• UNIT PRESSURE (ä 106)
Factory setting
OFF
PRESSURE TYPE Prerequisite
The function is only available if PRESSURE or PRESSURE 72 was selected in the HART
INPUT function (ä 167).
Description
For selecting whether the pressure value is read in as an absolute or gauge unit.
Options
GAUGE
ABSOLUTE
Factory setting
ABSOLUTE
AMBIENT PRESSURE Prerequisite
The function is only available if GAUGE was selected in the PRESSURE TYPE function
(ä 168).
Description
Use this function to enter the ambient pressure.
The appropriate unit is taken from the UNIT PRESSURE function (ä 106).
User input
5-digit floating-point number
Factory setting
1.0000
ERROR VALUE
TEMPERATURE
Prerequisite
The function is only available if TEMPERATURE or TEMPERATURE 72 was selected in
the HART INPUT function (ä 167).
Description
Use this function to enter a defined error value for the temperature process variable read
in. If Prowirl does not receive a valid value from the external temperature transmitter,
the process variable is set to the "error value" defined here and one of the error messages
#520 - #523 (ä 66) is generated.
The appropriate unit is taken from the UNIT TEMPERATURE function (ä 102).
User input
5-digit floating-point number
Factory setting
75 °C
