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.

X-Y Position Error reported in
Vision
DO NOT OPERATE OR
TROUBLESHOOT WITH THE
LID OPEN. SUNLIGHT MAY
CONFUSE THE OPTICAL
INTERRUPTERS USED TO
POSITION THE SAMPLE
CARRIAGE
1. Remove tray or sample cell from carriage and re-
position carefully.
2. Verify that nothing has caused the 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 X-Y Positioning error.
IMPORTANT NOTE: The operator should never
attempt to manually position, push, or force the
mechanism to any position. This can cause the X-Y
positioning assembly to “forget its position.” A
reset is required if this occurs.

X-Y Sampling Mechanism does
not move when using vial (or
tablet) tray
1. Click “Use Tray” in Select Tray Dialog box.
2. The X-Y mechanism may have shifted during
shipment, and has lost its “home position”.
Remove the Iris Adapter, if present, to prevent a
crash.
Enter Configure, then Select Tray Dialog box. Click
on “Use Iris”. Wait 60 seconds. (You may hear the
mechanism in operation during this time.) Next,
click on “Use Tray”. Vision will re-acquire the home
position of the X-Y mechanism, and will be ready
to operate.
