X-Y Sampling Mechanism
crashes into Iris Adapter,
causing Limit Switch Error
Remove Iris Adapter. Click “Use Iris” in Vial Dialog box.

mechanism, and will be ready to operate. Re-install the Iris
Adapter.

Sampling Mechanism does not
move when using large
sample cell
Click “Use Boat” in Vial Dialog box.
14 Instrument Cooling Fans do
not operate
1. Instrument may not be warmed up. Fans do not
operate until the instrument is near operating
temperature.
2. Ambient temperature may not require fan cooling.
This is common in cool environments.
To check fan operation, cycle the Power Switch.
Note if the fans come on for a short burst,
approximately 25 seconds after power, the fans
are operating properly.

Vision reports “Saturation”
This indicates that the energy reaching the detector(s) is
out of range, either too much or too little. This may be
caused by one of these situations:
1. In tablet transmission, the reference is not in the
correct position on the X-Y mechanism, and the
energy reaching the detector is too high. Verify
that “Use Tray” is selected under Configure, Tray.
2. Also in tablet transmission, the reference position
may be completely blocked, resulting in no energy
reaching the detector.
3. Verify that a sample is in the tray. In transmission,
an empty sample position (if selected for scanning)
may create a saturation error.
4. Lamp may not be installed correctly. (This is rare.)
