Error messages
D184B111U02 CoriolisMaster FCM2000 99
Error code and clear
text Priority Description Possible Causes Corrective Measures
Incorrect wiring
(only for remote design) Check wiring between flowmeter
primary and converter Error: 7b
T instrument housing
measurement 12 Erroneous temperature -
measurement
For the temperature compensation
of the measurement variable Qm
a density of 20°C is used, i.e. for a
fluid temperature near 20 °C the
measurements will be correct
Pt 100 is defective Check the resistance of PT100 on
the primary flowmeter
Error: 8a
Iout 1 too large 15 The current value is above the
programmed range for current
output 1. Range setting is too small Increase range setting
Error: 8b
lout 1 too small 16 The current value is below the
programmed range for current
output 1 Range setting is too small Increase range setting
Error: 8c
Iout2 too large 17 The current value is above the
programmed range for current
output 2. Range setting is too small Increase range setting
Error: 8d
lout 2 too small 18 The current value is below the
programmed range for current
output 2 Range setting is too small Increase range setting
Error: 9a
Density measurement 9 The measured density of the fluid
in the flowmeter primary is outside
of the specifications This error usually occurs together
with errors 1 and 9.
See errors 1 and 9 See errors 1 and 9
Error: 9b
Density <0.5 kg/l 10 The density of the medium in the
flowmeter primary is < 0.5 kg/l, the
volume totalizers are stopped The flowmeter primary is not
completely filled with fluid. Completely fill the flowmeter
primary
Error: 11a
Sensor A 23 The signal from Sensor A is
missing Sensor A is defective, or the
amplitude control circuit is open Measure resistance of Sensor A
For remote design: Check wiring
between flowmeter primary and
converter
Error: 11b
Sensor B 24 The signal from Sensor B is
missing Sensor B is defective, or the
amplitude control circuit is open Measure resistance of Sensor B.
For remote design: Check wiring
between flowmeter primary and
converter
Error: 11d
Sensor 5 The signal from at least two
sensors is missing At least two sensors are defective,
or the amplitude control circuit is
open Measure resistance of the
sensors.
For remote design: Check wiring
between flowmeter primary and
converter
Error: 12
Concentration Concentration below 0 % or above
103,125 %. The measured density or
temperature does not fit in the
given and chosen matrix Correct the chosen matrix
Error
prot. user trans Parameters cannot be changed The operating protection switch is
active Deactivate the hardware
protection switch.
