S149.021
Coil resistor
out of limits
Check wiring
Contact
ABB Service
Coil resistance too high: Coil or fuse
for coil circuit is defective, or M1/M2
wired incorrectly, or wire break, or fluid
is too hot.
Coil resistance too low: Coil is
defective or short circuit in M1/M2
wiring. Check wiring, check fuse for coil
circuit, contact ABB Service.
S148.025
Operation
Empty Pipe
Check Pipe The pipeline in the system is empty. Fill pipeline.
S146.043
Operation
Gas Bubble Alarm Gas bubbles were detected in the fluid.
The measured value is above the set
switching threshold. Check the process.
S144.033
Operation
Partially
filled pipe(TFE)
Check Pipe
Or adjust
Detector
Alarm tripped by Partial Filling
Detector. Check process, fill pipeline.
S143.042
Operation
Electrode
Coating Alarm
Insulating or conductive deposits
detected on measuring electrodes. The
deposit value is above the set
switching threshold. Check process, flush pipeline, clean
measuring electrodes.
S142.041
Operation
Conductivity Alarm The fluid conductivity is outside the
configured limit values. Check process, adjust alarm limits if
required.
S141.046
Operation
Sensor and or Housing
Temperature to high
The flowmeter sensor temperature is
outside the configured limit values. Check process, adjust alarm limits if
required.
S140.007
Operation
Flowrate >103%
Check Flowrate
Check Range
Setting
The flowrate in the system exceeds the
configured flow range end value by
more than 3 %. Increase the flow range end value in
the "Easy Set-up - Qmax" menu.
S136.006
Operation
Max Alarm
Flowrate
The current flowrate in the pipeline is
greater than the max. alarm
configured. Reduce the flowrate or increase the
value for the max. alarm.
S132.005
Operation
Min Alarm
Flowrate
The current flowrate in the pipeline is
lower than the min. alarm configured. Reduce the flowrate or increase the
value for the min. alarm.
