SIGNAL>LOW PASS
# 396
The device finds the signal outside the set filter range.
Possible causes:
• The flow is outside the measuring range.
• The signal is caused by a strong vibration which is
intentionally not measured and is outside the
measuring range.
• Check whether the device was installed in the flow direction.
• Check whether the right option was selected in the SELECT
FLUID function (ä 143).
• Check whether the operating conditions are within the
specifications of the measuring device.
Example:
flow is above measuring range which means that the flow may
have to be reduced.
If the checks do not solve the problem, please contact your
Endress+Hauser service organization.

HART-IN: NO VAL
# 520
The HART input functionality is enabled but the desired
value (e.g. pressure value) is not found in the HART
telegram.
• 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

HART-IN: DOUBLE
# 521
Two values of the same kind have been found in the
burst telegram. Prowirl cannot decide which of these
two values is to be used.
Make sure that only one pressure, temperature or density value is
in the burst telegram (BURST-OPTION = 1).

HART-IN: CHKSUM
# 522
The checksum of the burst telegram is not correct. Check if the wiring has been carried out according to the
