Overtempering
possible
1. Check if a leukapheresis product is lying within the scanning
area of the infrared sensor. If this is not the case, switch o
and on again the SAHARA-TSC. Place a cryo-preserved
leukapheresis product under the infrared sensor and start a
new tempering process.
2. Check whether the infrared sensor is lying completely
on the leukapheresis product and does not partly cover
the adaptation compress. The scanned surface of the
leukapheresis product must not show any protruding objects
(no additional packaging, detached labels etc.). Remove those
objects and start a new tempering process.

12 SAHARA-TSC service and maintenance
12.1 System test
By means of the integrated system test the device functions including the electromechanical components and temperature
sensors are checked in 10 steps.
The user performs the rst two testing steps. During these steps, the functionality of the LEDs and agitator mechanism must
be ensured via a visual inspection. The further test steps are performed automatically. The conclusion of each test step is
indicated by a short audible signal and the illumination of an LED of the degree of tempering display. The system test takes
about 30 – 40 minutes.
If a malfunction is observed by the user during the rst and second test step then SAHARA-III should be suspended from
usage and the after-sales service must be contacted. If a system error is detected during the following test steps, then
the system test will be automatically aborted and an error code is displayed in the FREE OF ICE LED or in the LEDs of the
degree of tempering display, as well as in the printout of the protocol printer if the corresponding module is connected.
An explanation of the dierent error codes as well as the appropriate measures are given in chapter 11.
