Checking The Instrument Log - PerkinElmer 200 UV/VIS Series User Manual

Configuring the Detector

Checking the Instrument Log

The Detector's Log screen shows you the lamp hours and display hours. The display hours
tell you how long the detector has been running. The lamp hours tell you how long the lamp
has been running. The number of hours are important for servicing the detector. The display
hours are reset when you clear the Battery Backed RAM. You should reset the lamp hours
when you install a new lamp. For more information on detector diagnostics, contact your
PerkinElmer service representative.
From the Log Screen you can access the Error Log screen. The Error Log screen displays the
date and time that errors occur during detector operation. The Error Log screen displays
errors for the following operations:
• LAMP FAILURE
The system has detected that the lamp has failed to light or has gone out during opera-
tion. The system will become NOT READY and the detector cannot be used. The solution
may be as simple as replacing the lamp. However the problem may be caused by other
electronic failure. If replacing the lamp does not clear the problem please contact your
local PerkinElmer service representative.
• FAN FAILURE
The system has detected that the fan is not turning, the lamp will be turned off (to pre-
vent overheating) and the system will go NOT READY. This problem cannot be customer
corrected and you should power down the instrument (again to prevent any over heating)
and contact your local PerkinElmer service representative.
• WL DRIVE FAILURE
The system has detected an error in one of the sensors used to determine the position of
the monochrometer. This error will render the detector unusable. It cannot be customer
corrected and you should contact your local PerkinElmer service representative.
• A/Z OUT OF RANGE
The system autozeros the output signal by attempting to balance the reference and sam-
ple signals. If the difference between these two signals is too great an autozero cannot be
achieved. The only customer correctable cause of this problem is if the sample flow cell
has been removed for some reason. Check that the sample flow cell is installed correctly.
If the cell is in place then the error is probably caused by a detector board problem and
you should contact your local PerkinElmer service representative.
