HART-IN: T.-OUT
# 523
The HART input is activated but Prowirl has not found a
burst telegram for some time.
!
Note!
The time limit for the occurrence of this error message is
specified in the TIMEOUT HART COM function.
• Check if the pressure, temperature or density sensor is HART-
enabled and is in the BURST mode.
• Check if the wiring has been carried out according to the
diagrams on ä 30.
S
$
SIGN DELTA HEAT
# 524
The algebraic sign of the temperature differential is
different to what Prowirl 73 expected.
• If the error message occurs when commissioning the
measurement, check the setting in the INSTALLATION POINT
function (ä 157).
• If the error message occurs during operation, check whether
the algebraic sign for the temperature differential has changed.
!
Note!
Prowirl 73 cannot take a change in the algebraic sign for
temperature measurement into account!
