The counter UVLampOperationTime (value: x hours) has
exceeded its limit (x hours). Module should no longer be
used. Replace the UV lamp.
The counter VISLampOperationTime (value: x hours) has
exceeded its limit (x hours). Module should no longer be
used. Replace the VIS lamp.
This error occurs if the number of hours the deuterium or tungsten lamp has
been in use exceeds the value set by the UVLampOperationTime.Limit or
VISLampOperationTime.Limit parameter.
To troubleshoot:
1. If your application is not overly sensitive to noise, increase the value of
the lamp operation time limit (UVLampOperationTime.Limit or
VISLampOperationTime.Limit command) in the Chromeleon 7
Command window or Chromeleon 6.8 Commands dialog box.
The default limit is 2500 hours. However, some applications are more
sensitive to noise and the default limit should not be changed.
2. Replace the deuterium lamp (P/N 066347) (see
tungsten lamp (P/N 066348) (see
Critical module failure.
To troubleshoot:
1. Turn the Dionex VWD power off and back on again.
2. If the message occurs again, contact Thermo Fisher Scientific for
assistance.
