7.2 Fault Number List
Fault
Number
Description Recommended Action
1 Zero motor
jammed. Check the Zero Reflector drive mechanism. Warning -
Do not move the mechanism by hand or the precision
gearbox may be irreparably damaged.
2 Upscale motor
jammed.
Check the Upscale Filter drive mechanism.
Warning - Do not move the mechanism by hand
or the precision gearbox may be irreparably
damaged.
3 Source LED failed Check the Source LED connections. Replace the
Source LED Assembly.
4 Flood LED failed Check the Flood LED connections. Replace the
Flood LED Assembly.
5 ADC Over-range The signal arriving at the Analogue-to-Digital
Converter is too large. Check that the correct
reflector element and aperture plate are
fitted in the Retro-reflector. Replace the
Detector PCB. Warning - The Detector PCB
must be optically aligned.
6 ADC Fault
The Analogue-to-Digital Converter is not
working. Replace the Detector PCB. Warning -
The Detector PCB must be optically aligned.
13 Negative Opacity
Check that the installation pathlength is correct.
Perform a Clear Stack Calibration.
14 Checksum Error The microprocessor’s program memory is
defective. Re-program the Main PCB. Change
the Main PCB. Warning - All the instrument
settings and calibration constants are stored on
the Main PCB. Re-enter this data after changing
the PCB.
15 Lens
Contamination
Limit The zero drift correction system has reached
its limit. Clean the main lens. Perform a
Calibration Check. If the problem persists,
make sure the Zero Reflector is clean. Note
that this fault can only be cleared by a
successful Calibration Check or Clear Stack
Calibration.
16 Failure during
Calibration
Something has prevented the completion of
calibration. User actions can cause this fault.
Perform a Calibration Check. If the problem
persists, check the Zero Reflector and
Upscale Filter drive mechanisms. Warning
- Do not move either mechanism by hand or the
precision gearbox may be irreparably damaged
Note: When contacting ENVEA Service Department, please have the Instrument Type and
Serial Number available. This will ensure a more accurate and efficient response.
