Operation Turb PLUS 2000
100193 Rev 0 ba77254e01 11/2020 53
Certain routine maintenance items, such as calibration and desiccant change,
are triggered by internal diagnostic alerts. The time to take other routine
maintenance tasks, such as removal of flow through to manually clean
cuvette, will vary based on system usage and water quality conditions.
Cleaning the Flow-Through Cuvette
Measurement cuvettes used for both the grab sample and the flow through should be clean and
free of marks or scratches. It is recommended to check, and if required clean, the cuvette every
three months when performing the primary calibration. The flow-through assembly must be
removed to perform the calibration procedure.
Cleaning is accomplished by cleaning the interior and exterior with a detergent solution and then
rinsing several times with distilled or de-ionized water.
The cuvette can be replaced by first shutting off the flow using the provided shutoff clamp;
unscrewing the old cuvette and replacing with a fresh clean one.
Replacing the Source Lamp
The source lamps in the Turb PLUS 2000 instruments are designed for long life. The IR lamp and
white light version have long lives. These lamps, however, are not covered by the warranty. If the
lamp should need replacement, we recommend calling Xylem Analytics Germany for assistance.
Optional Factory Installed 24V Option
This factory installed option allows for the operation of the Turb PLUS 2000 from 24 volts DC. For
this instrument, the changes are in the junction box only.
The range of correct operation is from 18-36VDC. Caution must be used to not exceed this
voltage.
Connections are not polarity sensitive and are made to the same place as mentioned in section
3.4.1.
