Cause
The temperature sensor on the
measuring tube is likely defective.
The temperature sensor on the
carrier tube is likely defective.
One of the measuring tube sensor
coils (inlet) is likely defective.
One of the measuring tube sensor
coils (outlet) is likely defective.
One of the measuring tube sensor
coils is probably faulty.
Amplifier error
New amplifier or communication (I/
O module) software version is
loaded. Currently no other functions
are possible.
Up- or downloading the device data
via configuration program. Currently
no other functions are possible.
The fluid properties do not allow a
continuation of the measurement.
Causes:
– Extremely high viscosity
– Process fluid is very
inhomogeneous (gas or solid
content)
Extreme process conditions exist.
The measuring system can therefore
not be started.
Overdriving of the internal analog to
digital converter.
Possible causes are cavitation,
extreme pressure shock and high
flow velocity for gases
A continuation of the measurement
is no longer possible!
Remedy / spare part
Check the following electrical connections before
you contact your Endress+Hauser service
organization:
– Verify that the sensor signal cable connector is
correctly plugged into the amplifier board.
– Remote version:
Check sensor and transmitter terminal
connections No. 9 and 10.
Check the following electrical connections before
you contact your Endress+Hauser service
organization:
– Verify that the sensor signal cable connector is
correctly plugged into the amplifier board.
– Remote version:
Check sensor and transmitter terminal
connections No. 11 and 12.
Check the following electrical connections before
you contact your Endress+Hauser service
organization:
– Verify that the sensor signal cable connector is
correctly plugged into the amplifier board.
– Remote version:
Check sensor and transmitter terminal
connections No. 4, 5, 6 and 7.
Contact your Endress+Hauser service organization.
Wait until process is finished.
The device will restart automatically.
Wait until process is finished.
Change or improve process conditions.
Change or improve process conditions.
Change or improve process conditions, e.g. by
reducing the flow velocity.
