Visible lamp error while attempting to turn on.
Visible lamp failed to turn on for the required operation.
To troubleshoot:
1. Check that the lamp referred to in the error message is turned on. When a
lamp is on, the corresponding LED (DEUTERIUM – UV or TUNGSTEN –
VIS) is lighted. If necessary, turn on the lamp from Chromeleon or the
TTL input.
2. If you recently installed a new deuterium lamp, check that the UV lamp
connector wires are routed through the wire guide in the optical bench
(see Figure 5-3) and are not pinched under the lamp cover.
3. Check the number of hours the lamp has been in service:
Open the Chromeleon 7 Command window (see page 31) or the
Chromeleon 6.8 Commands dialog box (see page 32), and then select UV.
If the error message relates to the deuterium lamp, execute the
UVLampAge command.
