Alarm name
Alarm description
Trigger
Consequence
Possible cause (Troubleshooting)
SP1 Low Flow
[A126]
Water flow through
measurement
chamber too low
while SP1 active.
Alarm is activated if
there is not detected
enough flow from flow-
switch while sample
point 1 is active.
Power for sample pump 1 to
be disconnected, and the
sample point ignored in the
cyclical sampling sequence.
All stored sensor values for
SP1 to be set to -1.
1. Defect pump impeller in WSU 1 pump
2. Leakage in sample point 1 pipe line
3. Blockage in sample point 1 pipe line
4. Defect solenoid valve for sample point
1
5. Too high resistance in discharge pipe
line
6. Any manual valve in sample point 1
pipe line closed
7. Shaft seal in WSU 1 pump is defect
SP2 Low Flow
[A134]
Water flow through
measurement
chamber too low
while SP2 active.
Alarm is activated if
there is not detected
enough flow from flow-
switch while sample
point 2 is active.
Power for sample pump 2 to
be disconnected, and the
sample point ignored in the
cyclical sampling sequence.
All stored sensor values for
SP2 to be set to -1.
1. Defect pump impeller in WSU 2 pump
2. Leakage in sample point 2 pipe line
3. Blockage in sample point 2 pipe line
4. Defect solenoid valve for sample point
2
5. Too high resistance in discharge pipe
line.
6. Any manual valve in sample point 2
pipe line closed
7. Shaft seal in WSU 2 is defect
SP3 Low Flow
[A142]
Water flow through
measurement
chamber too low
while SP3 active.
Alarm is activated if
there is not detected
enough flow from flow-
switch while sample
point 3 is active.
Power for sample pump 3 to
be disconnected, and the
sample point ignored in the
cyclical sampling sequence.
All stored sensor values for
SP3 to be set to -1.
1. Defect pump impeller in WSU 3 pump.
2. Leakage in sample point 3 pipe line
3. Blockage in sample point 3 pipe line
4. Defect solenoid valve for sample point
3
5. Too high resistance in discharge pipe
line
6. Any manual valve in sample point 3
pipe line closed
7. Shaft seal in WSU 3 is defect
SP4 Low Flow
[A150]
Water flow through
measurement
chamber too low
while SP4 active.
Alarm is activated if
there is not detected
enough flow from flow-
switch while sample
point 4 is active.
Power for sample pump 4 to
be disconnected, and the
sample point ignored in the
cyclical sampling sequence.
All stored sensor values for
SP4 to be set to -1.
1. Defect pump impeller in WSU 4 pump
2. Leakage in sample point 4 pipe line
3. Blockage in sample point 4 pipe line
4. Defect solenoid valve for sample point
4
5. Too high resistance in discharge pipe
line
6. Any manual valve in sample point 4
pipe line closed
7. Shaft seal in WSU 4 is defect
