Table D.4. Faults, failures, alarm situations and troubleshooting
Event type
Probable cause
Troubleshooting method
1. Display failure
1. Faulty power supply
2. Faulty prevented.
1. Replace power supply.
2. Replace prevented.
2.
No signal
1. Incorrect adjustment of the
flowmeter.
2. Pipeline is not filled with liquid, or
there's too much gas in the liquid.
3. Faulty electric connections be-
tween PEA and CS.
4. Faulty mounting of the clamp-on
PEAs on the pipeline.
5. Sediments on the inner surface of
the pipeline.
6. Faulty PEA.
7. CS failure.
1. Make sure that the parameters are set
correctly.
2. Make sure that the pipeline is filled with
liquid, and that there're not considerable
air bags present.
3. Check integrity and reliability of electric
connections between PEA and CS.
4. Check mounting correctness and quali-
ty of fastening of PEAs to the pipeline,
and that there is lubricant present under
the radiating surface of the clamp-on PEA.
5. Install PEA on another section if the
signal level is insufficient.
6. Check functionality of the channel with
other PEAs.
7. Contact the Service Center.
3.
Q
Qmax
Measured flowrate value has ex-
ceeded the allowed value.
Make sure that the parameters are set
correctly.
4.
Q
Qut
Flowrate exceeds the frequency out-
put upper limit
Make sure that the parameters are set
correctly.
5.
Q
Qlt
Flowrate is less than the frequency
output upper limit
Make sure that the parameters are set
correctly.
6.
Q
Qlt1
;
Q
Qlt2
Flowrate is less than the current out-
put lower limit
Make sure that the parameters are set
correctly.
7.
Q
Qut1
;
Q
Qlt2
Flowrate exceeds the current output
upper limit
Make sure that the parameters are set
correctly.
8.
F > Fmax
Frequency corresponding to the cur-
rent flowrate exceeds the maximum
allowed value.
Make sure that the parameters are set
correctly.
9.
Q
Qut
Flowrate exceeds the high setpoint
Make sure that the parameters are set
correctly.
10.
Q
Qlw
Flowrate is less than the low setpoint Make sure that the parameters are set
correctly.
11.
Oper.er.
Wrong PS parameter values
Check correctness of set PS parameters
