Message Description Solution
Monthly
maintenance has
failed! Chlorine carryover from
colorimeter disinfection
process.
1. Do monthly maintenance again.
2. During the disinfection step, pour 200 mL of RO water through
the funnel instead of the bleach solution.
3. Enter the reagent lot codes, but do not replace the reagents.
4. Refill the zero standard bottle with RO water and pour it through
the funnel as instructed by the instrument.
To prevent future carryover failures:
1. Pour the bleach solution into the funnel slowly. Only fill the
funnel halfway then allow it to drain before pouring in the
remainder of the bleach solution. Take care not to splash
bleach on the walls of the funnel.
2. When rinsing the funnel with 200 mL RO water, fill the funnel to
a higher level than with the bleach solution.
3. When pouring in the 100 mL of zero standard water, only allow
it to fill the funnel halfway. Allow it to drain before pouring the
remainder of the water in.
Other problems can occur if light is shined into the colorimeter
during the reagent evaluation process.
If the problem continues, increase the volume of RO water added to
the funnel and examine the sample water for excessive bubbles.
Periodic
maintenance
required! The colorimeter has
been installed for more
than the allowable use
life or there is a
problem with the
colorimeter. Do periodic maintenance. Refer to Periodic maintenance
on page 59.
The colorimeter cable
is not fully connected. With the analyzer power off, disconnect and the connect the
colorimeter connector again to make sure that the colorimeter cable
is fully connected.
Reagent blank
out of range There is too much color
in the reagents. Complete the steps for "Monthly maintenance has failed".
If the problem continues, the reagents may be contaminated. Do
monthly maintenance. Refer to
Monthly maintenance on page 58.
Reagent delivery
error! The reagent level is
0%. If one or two reagent bottles are almost empty, do monthly
maintenance. Refer to
Monthly maintenance on page 58.
There is a problem with
the reagent delivery
module or the
colorimeter tubing.
1. Make sure that the colorimeter and the reagent delivery board
are installed correctly. Make sure that the reagent delivery
connector is installed in the reagent delivery board. Refer to the
instructions for use supplied with the colorimeter.
2. Push menu , then select Maintenance > Prime reagents.
3. If the problem continues, remove power from the analyzer.
Refer to
Remove power on page 61. Refer to the clinic
operating procedures.
4. Do periodic maintenance to replace the pump tubing and the
colorimeter. Refer to
Periodic maintenance on page 59.
5. If the problem continues, replace the reagent delivery module.
Refer to the instructions for use supplied with the new reagent
delivery module.
The reagent delivery
connector is not fully
installed in the reagent
delivery board. Remove power from the analyzer. Disconnect and reconnect the
reagent delivery connector. Refer to the instructions for use
supplied with the colorimeter. Make sure that there is no strain on
the reagent delivery cable.
