Instrument cooling fans are
operating at maximum rate.
1. Verify that air intake on side is not blocked by other
equipment. Leave at least 3-4 inches (76-102mm) space by
intake fins for proper airflow.
2. Verify that air filter is clean. If not, clean or replace filter.
If fan speeds dropped shortly after opening fan filter door,
this is a sign of a blocked filter.
3. Verify that the fan exhaust area is not blocked, restricting
the fan outflow. Leave at least 3-4 inches (76-102mm)
space in by fan exhaust for proper airflow.
4. Check ambient temperature in area where instrument is
used. If temperature is near the maximum, fan flow will be
high.

Limit Switch Error reported
in Vision
1. Remove sample cell from carriage and re-position
carefully.
2. Verify that nothing has caused the sample transport
mechanism to become stopped, jammed, or manually re-
positioned.
To reset:
Click “OK” in the dialog box containing the Limit Switch
Error message. Disconnect from the instrument, cycle
instrument power, then re-connect. This will clear the limit
switch error.
IMPORTANT NOTE: The operator should never attempt to
manually position, push, or otherwise force the mechanism
to any position. This can cause the assembly to “forget its
position.” A reset is required if this occurs.

Sample Carrier does not
move when using large
sample cell
Set “Cell” in Data Collection Method (DCM) to “Moving”.

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.

Software “freezes” or
“lockups” during use
Usually caused by use of two network cards in PC. Data
collisions are causing lost communication “packets”.
Remove one NIC card, and use the connection method on
page 4.
