Table 13 Alarms (red )
Message Description Solution
Bubbles
detected!
There are bubbles or
turbidity in the sample.
Decrease the sample water temperature if possible.
Make sure that the sample water is not turbid.
Make sure that a light source is not pointed at the colorimeter (e.g.,
flashlight).
If the alarm continues, there may be biological growth in the
colorimeter. Do all of the steps of monthly maintenance. Refer to
Monthly maintenance on page 58.
If the problem continues after monthly maintenance, do periodic
maintenance to replace the colorimeter. Refer to Periodic
maintenance on page 59.
If the problem continues after periodic maintenance, the analyzer
may be exposed to a combination of air bubbles and chlorine below
the limit of detection.
The colorimeter cable
is not fully connected.
Remove power from the analyzer. Disconnect and reconnect the
colorimeter cable. Make sure that there is no strain on the
colorimeter cable.
Chlorine above
measurement
range!
The chorine level is
more than 0.20 mg/L
(ppm).
Refer to the clinic operating procedures.
If this alarm occurs immediately after monthly maintenance, add
200 mL (or more) of RO (reverse osmosis) water through the
sample funnel. Then flush the colorimeter three times to remove
any chlorine added during the bleach disinfection procedure. Select
Menu > Maintenance > Flush Colorimeter.
Note: Different substances (e.g., chlorine compounds and oxidants) can
interfere with chlorine measurements. Refer to Interferences on page 72. If
necessary, determine if there are interfering substances in the sample water.
Condensation
detected!
There is condensation
on the optical surfaces
of the colorimeter.
Make sure that the temperature and humidity in the water room are
within specification. Refer to Specifications on page 3.
If the problem is not continuous, put the analyzer back in
measurement mode.
If the problem is continuous, do periodic maintenance. Refer to
Periodic maintenance on page 59.
The colorimeter cable
is not fully connected.
Remove power from the analyzer. Disconnect and reconnect the
colorimeter cable. Make sure that there is no strain on the
colorimeter cable.
Electronics error! A front panel failure has
occurred.
The clock battery voltage is low or a main board failure has
occurred. Contact technical support.
Excess sample
flow
Sample flow has been
sensed at a time when
sample flow should be
stopped.
Adjust the sample pressure so that it is within the instrument
requirements. Refer to Specifications on page 3.
Look at the clear (drain) tubing during the measurement cycle. If the
sample flow does not stop after approximately 75 seconds, the
sample flow rate is too high.
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.
High chlorine! The chorine level is
more than 0.10 mg/L
(ppm).
Refer to the clinic operating procedures.
Note: Different substances (e.g., chlorine compounds and oxidants) can
interfere with chlorine measurements. Refer to Interferences on page 72. If
necessary, determine if there are interfering substances in the sample water.
