9.3 Process error messages
!
Note!
• The listed error message types below correspond to the factory setting.
• See also the information on → ä 31.
MODBUS No. Device status message
(local display)
Cause Remedy / spare part
Register:
6859
Data type:
Integer
Register:
6821
Data type:
String (18 byte)
Response to a fault message:
The value "NaN" (not a number) is
transmitted to the MODBUS master
instead of the current measured
value.
Depicted on the local display:
S = System error
$ = Fault message (with an effect on the outputs)
! = Notice message (without any effect on the outputs)
1SYSTEM OK–
There is no error present in the device
No. # 7xx → Other process errors
111 EMPTY PIPE 700 P: EMPTY PIPE
!: # 700
The process fluid density is
outside the upper or lower
limit values set in the "EPD"
function.
Causes:
– Air in the measuring tube
– Partly filled measuring
tube
1. Ensure that there is no gas content in the process
liquid.
2. Adapt the values in the "EPD RESPONSE TIME"
function to the current process conditions.
112 EXC. CURR. LIM 701 P: EXC. CURR. LIM
!: # 701
The maximum current value
for the measuring tube
exciter coils has been
reached, since certain process
fluid characteristics are
extreme, e.g. high gas or solid
content.
The device continues to work
correctly.
In particular with outgassing fluids and/or increased
gas content, the following measures are recommended
to increase system pressure:
1. Install the device at the outlet side of a pump.
2. Install the device at the lowest point of an
ascending pipeline.
3. Install a flow restriction, e.g. reducer or orifice
plate, downstream from the device.
113 FLUID INHOM. 702 P: FLUID INHOM.
!: # 702
Frequency control is not
stable, due to
inhomogeneous process fluid,
e.g. gas or solid content.
114 NOISE LIM. CH0 703 P: NOISE LIM. CH0
!: # 703
Overdriving of the internal
analog to digital converter.
Causes:
– Cavitation
– Extreme pressure pulses
– High gas flow velocity
A continuation of the
measurement is still possible!
Change or improve process conditions, e.g. by
reducing the flow velocity.
115 NOISE LIM. CH1 704 P: NOISE LIM. CH1
!: # 704
116 FLOW LIMIT 705 P: FLOW LIMIT
$: # 705
The mass flow is too high.
The electronics' measuring
range will be exceeded.
Reduce flow.
124 ADJ. ZERO FAIL. 731 P: ADJ. ZERO FAIL
!: # 731
The zero point adjustment is
not possible or has been
canceled.
Make sure that zero point adjustment is carried out at
"zero flow" only (v = 0 m/s).
