Proline Prowirl 73 Description of device functions
Endress+Hauser 169
ERROR VAL. PRESS Prerequisite
The function is only available if PRESSURE or PRESSURE 72 was selected in the HART
INPUT function (ä 167).
Description
Use this function to enter a defined error value for the pressure 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.
Enter an absolute pressure in this function. If GAUGE was selected in the PRESSURE
TYPE function, the gauge pressure is calculated with the value in the AMBIENT
PRESSURE function.
The appropriate unit is taken from the UNIT PRESSURE function (ä 106).
User input
5-digit floating-point number
Factory setting
10 bar a
ERROR VALUE DENS Prerequisite
The function is only available if DENSITY or DENSITY 72 was selected in the HART
INPUT function (ä 167).
Description
Use this function to enter a defined error value for the density 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 DENSITY function (ä 104).
User input
5-digit floating-point number
Factory setting
1 kg/l
TIMEOUT HART
COMMUNICATION
Prerequisite
The function is not available if OFF was selected in the HART INPUT function
(ä 167).
Description
Use this function to enter the number of seconds that have to elapse before the external
sensor outputs the error message "#523 TIMEOUT HART COM" (ä 66) if
communication via HART fails or does not take place.
User input
0 to 100 s
Factory setting
60 seconds
