UTOSAMPLER
CE 6–45
Error Messages
Parameter Error
Zero-Power RAM
Problem: The confidence test has detected that
one or more of the calibration values
has been altered.
Solution: When the confidence tests finish, test
all of the Autosampler CEs calibration
positions (see Checking Your Cali-
bration in Chapter 4), and recalibrate
the position(s) that have been erased.
R step error
+xxxxx steps
(or xxxxx steps)
Problem: The r-axis motor executed the wrong
number of steps to complete a move-
ment. The number is positive when the
motor is retracting, and negative when
the motor is extending. Small numbers
of lost steps (<25) indicate a loose or
worn gear, whereas frequent errors
involving larger numbers indicate that
the motor is binding.
Solution: The Autosampler CE immediately
corrects for motor step errors, so this
error condition usually does not require
any operator action. If your Autosam-
pler CE starts showing step errors
with increasing frequency, however,
you should have the unit serviced.
