| Turn on the lamp once more. Check if a UV lamp is installed. Check the lamp connector. Check that the lamp cover is installed properly. If the message appears again, replace the UV lamp (see Replacing the UV Lamp (Deuterium Lamp)). |
| Turn on the lamp once more. Check if a VIS lamp is installed. Check the lamp connector. Check that the lamp cover is installed properly. If the message appears again, replace the VIS lamp (see Replacing the VIS Lamp (Tungsten Lamp)). |
| Check the USB connection. Use only the USB cables provided by Thermo Fisher Scientific for the detector. Avoid CPU-intensive and time-consuming operations on the PC during high-speed data acquisition. |
| Make sure that either the UV and/or VIS lamp are on. Operation can be performed only if any of the lamps or both lamps are on. |
| Check the lamp installation. |
| Check if the environmental conditions (ambient humidity and ambient temperature) are within the specified operating range (see Physical Specifications). Check the flow cell (see Checking the Flow Cell). Run the detector over night (at least 12 hours, recommended 24 hours) with an installed diagnostic cell and with the UV lamp (and VIS lamp, if available) turned on. If the message still appears, install a different flow cell or a diagnostic cell. Turn on any lamp (UV or VIS) and perform an auto-zero. |
| With xx = system or lamp house, yy = the number of seconds before emergency standby or shutdown is entered An over-temperature condition was detected. Turn off the detector and let the detector cool down. Check that the detector is operated within the specified environmental conditions (ambient temperature), see Physical Specifications. Check the cooling air intake and the ventilation holes on the rear side of the detector for dust. If dust is present, aspirate the dust and loose particles with a vacuum cleaner. |
| Check the flow cell (see Checking the Flow Cell). If the message still appears, proceed as follows: Check the lamps: If a lamp was newly installed, ensure that it is installed properly. If a lamp is old (counting, for example, more than 2000 operating hours), replace the lamp (see Lamps). |
| The flow cell is not correctly positioned inside the flow cell opening. Check the flow cell installation (see Checking the Flow Cell). Check the flow cell contact pins for proper alignment inside the flow cell opening. |
| Repeat the validation (see Performing a Wavelength Validation and Calibration). If the message still appears, proceed as follows: Perform a calibration and repeat the validation again. Remove and install the flow cell. Flush the flow cell with pure HPLC-grade water with a flow rate of > 1 mL/min for several minutes (Nano flow cells: Flush with pure HPLC-grade water with the maximum possible flow rate for the respective range for several minutes). Install a different flow cell or a diagnostic cell (see Installing a Flow Cell or Installing a Diagnostic Cell). Perform a validation. Perform a calibration and repeat the validation again. If the message disappears with a different cell, the flow cell that was previously installed may be clogged. If the error message persists, contact Technical Support. |
