Section 4

Troubleshooting

4 - 1

This section is designed to guide the service technician through basic procedures
to be used in determining the cause of various machine errors.  Diagnostic
techniques do not take the technician beyond board-level analysis.  If an error
exists on a particular circuit board, replace the entire board.

4.1
Error Messages

A number of error messages are generated by the spectrophotometer to indicate
improper operations.  These are displayed for the operator (and explained in the

GENESYS 20 Operator's Manual

) and can normally be resolved without further

troubleshooting.  They are  included here for the convenience of the Service
Technician.

The instrument generates two types of errors.  With the first type, a warning
signal is generated and the error message displays briefly, but the instrument is
still functional.  With the second type of error, the error message remains and the
instrument is not functional until the condition is resolved.

Flashing Data Display

Indicates the sample has an absorbance or
transmittance value below or above the photometric
range of the instrument. The display flashes until the
condition is resolved.

Lamp Failure

Indicates the lamp has failed.  The message remains
on the display until the lamp is replaced.

Sample too dark

Indicates the instrument has been asked to zero a
sample with a high absorbance at a low energy point.
The instrument beeps three times to announce the
message, the message remains on the display for two
seconds, then the normal display returns.

Sample too bright

Indicates the instrument has been asked to zero a
sample while the door of the sample compartment is
open.  The instrument beeps three times to announce
the message, the message remains on the display for
two seconds, then the normal display returns.
