PROBLEM / CONDITION
SOLUTION
Temperature
Internal temperature of the
analyzer is approaching maximum
recommended operating
temperature.
It may be necessary to relocate the analyzer to a cooler
location or if it is outside it could require shading from the
sun.
UVT Warning
UVT value is approaching the
operator setpoint.
Flow cell is dirty and needs to be cleaned OR a grab sample
should be obtained and compared to the sample water to
confirm measurement.
UVT Alarm
UVT value is below the operator
setpoint.
Flow cell is dirty and needs to be cleaned OR a grab sample
should be obtained and compared to the sample water to
confirm measurement.
UVA Warning
UVA value is approaching the
operator setpoint.
Flow cell is dirty and needs to be cleaned OR a grab sample
should be obtained and compared to the sample water to
confirm measurement.
UVA Alarm
UVA value is above the operator
setpoint.
Flow cell is dirty and needs to be cleaned OR a grab sample
should be obtained and compared to the sample water to
confirm measurement.

Rotation position 1 means the lamp is oriented to measure flow cell at the 2 cm path length. Rotation position 2
means the lamp assembly has rotated 90 degrees to measure the path length of 1 cm. In positions 1 and 2, the
lamp’s values should be identical as the distance between the lamp and sensor is constant.
If all six numbers display 0, this indicates the system did not start up correctly (refer to the diagnostic LED’s). If
Lamp and Water numbers are 0 but humidity and temperature data appears to be correct then this indicates a
communication problem with the sensor board located on the rotating assembly.
