Description of device functions Proline Prowirl 73
178 Endress+Hauser
MAX T ELECTRONCS Description
Highest temperature measured at the electronics board since the last reset (RESET T
ELECTR. function ä 178).
Display
5-digit floating-point number, incl. unit and sign
e.g. 65.3 °C
RESET T ELECTR. Description
Reset the values in the MIN T ELECTRONCS (ä 177) and MAX T ELECTRONCS
functions (ä 178).
Options
NO
YES
Factory setting
NO
WARN T ELECTR. LO Description
Use this function to enter the lower limit value for monitoring the temperature on the
electronics board. This limit value is used to generate a fault message which is intended
to indicate that the fluid temperature is changing in the direction of the specification
limits of the device in order to prevent device failure or to prevent the process from
overcooling.
The appropriate unit is taken from the UNIT TEMPERATURE function (ä 102).
User input
5-digit floating-point number, including sign
Factory setting
–52 °C
WARN T ELECTR. HI Description
Use this function to enter the upper limit value for monitoring the temperature on the
electronics board. This limit value is used to generate a fault message which is intended
to indicate that the fluid temperature is changing in the direction of the specification
limits of the device in order to prevent device failure or to prevent the process from
overcooling.
The appropriate unit is taken from the UNIT TEMPERATURE function (ä 102).
User input
5-digit floating-point number, including sign
Factory setting
86 °C
SENSOR DIAGN. Description
Use this function to monitor the capacitive signal of the DSC sensor. The monitoring
function checks what range the capacitive signal of the DSC sensor is in.
