Motor Errors

Monochromator motor errors may show up during the initialization or during operation
NOTE
of the detector.
There are individual messages for either the excitation or the emission side.
If an error occurs, do a lamp ignition. This will clear the error and a re-initialization of
the motors is performed.

Description
During initialization of the
detector, the excitation and
emission monochromator
are activated.
During initialization of the
detector, the excitation-
and emission
monochromator are
activated and the encoder
should generate an index.
Description
Probable Causes
encoder cables mixed on
FLM board
monochromator
assembly not connected
monochromator or
encoder defective
monochromator motor
power driver defective
encoder defective
encoder electric defective
monochromator defective
or missing one phase
monochromator motor
power driver defective
Probable Causes
Suggested Actions
check encoder connections
to FLM
check motor connections
to FLF (Ex) and FLM (Em)
and encoders to FLM
replace monochromator
assembly
defective FLF board (Ex) or
FLM board (Em)
replace monochromator
assembly replace FLM
board check for connection
to FLF (Ex) and FLM (Em) or
replace monochromator
assembly
defective FLF board (Ex) or
FLM board (Em)
