Metrohm NIRS XDS MultiVial Analyzer - Manual (Page 38)

The sample transport mechanism is quite rugged, and requires no service by the user. Please
observe these cautions:
• Never attempt to move the mechanism manually. This will cause a “Limit Switch Error” in
Vision. The user must then disconnect, cycle power, and re-connect to the instrument to
reset the mechanism.
• DO NOT operate with the lid open. This can induce X-Y Positioning Errors.
• Do not attempt to clean or lubricate the mechanism. The traversing nut is self-lubricating
and self-cleaning, and requires no service of any kind. The lead screw is stainless steel, and
needs no service.
There are no user-serviceable parts in the mechanism. It has been aligned and set for quiet, stable
operation. Please be gentle, and do not attempt to make any adjustments.
5.5.1 Use of the Iris Adapter:
When using the Iris Adapter, select the “Use Iris”
setting in the Select Tray dialog Box. This
positions the sample carrier to a central position,
and permits the user to install the Iris Adapter.
(The Iris Adapter is shown in the next photo.)
NOTE: Failure to set the “Use Iris” setting may
result in damage to the instrument, which is not
covered by instrument warranty.
When set to “Use Iris” Vision ignores the tray
sizes shown on the left side of this dialog box,
and proceeds only for use of the Iris Adapter.
Gently position the Iris Adapter over the locating
pins and press downward.
This photo shows the Iris Adapter in the correct
position for use. Note the silver positioning lever
at the left side of the iris – move this lever right
to close the iris to centering vials or other cells.
DO NOT OPERATE OR TROUBLESHOOT WITH THE LID OPEN. SUNLIGHT MAY CONFUSE
THE OPTICAL INTERRUPTERS USED TO POSITION THE SAMPLE CARRIAGE. THIS MAY
CAUSE AN “X-Y POSITIONING ERROR” TO BE REPORTED.
