Error Information
Detector Error Messages
Encoder Index Not Found
Error ID: EX 6707, EM 6708
During initialization of the detector, the excitation- and emission
monochromator are activated and the encoder should generate an index.
Motor Friction Too High
Error ID: EX 6709, EM 6710
During initialization of the detector, the excitation and emission grating
resistance test provides the resistance history of the excitation and the
emission grating drives. The number of revolutions after switching off the
drives is a measure of friction. The history may show an increasing friction of
the drive(s) over a length of time.
Probable cause Suggested actions
1
Encoder defective.
Replace monochromator assembly.
2
Encoder electric defective.
Replace FLM board.
3
Monochromator defective or missing.
Check for connection to FLF (Ex) and FLM (Em)
or replace monochromator assembly.
4
One phase monochromator motor power
driver defective.
Defective FLF board (Ex) or FLM board (Em).
Probable cause Suggested actions
1
Friction too high.
Replace monochromator assembly.
2
Defective monochromator assembly.
Replace monochromator assembly.
