Table 13 Alarms (red ) (continued)
Message Description Solution
Insufficient
sample flow
The sample flow rate is
too low.
Make sure that the sample source valve and the shut-off valve for
the analyzer are open (turned counter-clockwise).
Make sure that the sample line is connected to the sample source.
Adjust the sample pressure so that it is within the instrument
requirements. Refer to Specifications on page 3.
If this alarm occurs when the sample pressure is within
specification, make sure the sample filter is correctly installed. Refer
to Items to collect on page 14 for the sample filter specifications.
If the problem continues, replace the sample conditioning module.
The sample flow rate is
too high.
Refer to the solution for the message "Excess sample flow" to
identify if the sample flow is too high.
Measurement
error!
The analyzer is not
able to do a
measurement.
Put the analyzer back in measurement mode. If the problem occurs
again, do the steps that follow:
1. Make sure that sample inlet (black) tubing is open to the
analyzer.
2. Make sure that the sample water is not turbid.
3. Make sure that the sample is within specifications. Refer to
Specifications on page 3.
4. Make sure that there is no air (bubbles) in the sample inlet
(black) tubing, including very small bubbles.
5. Make sure that the temperature and humidity in the room are
within specifications. Refer to Specifications on page 3.
6. Make sure that no intermittent light sources are shining on the
colorimeter.
7. Push menu, then select Maintenance > Flush colorimeter.
8. Push menu, then select Maintenance > Prime Reagents.
9. Make sure that water flows out the drain tubing.
10. If the problem continues, put the analyzer back in measurement
mode.
11. Examine the drain tubing for sample flow when the
measurement cycle is between 30% and 90%.
12. If flow is seen, replace the sample conditioning module.
13. If the problem continues, do periodic maintenance. Refer to
Periodic maintenance on page 59.
Monthly
maintenance
required!
The reagent level is 0%
