Safety advice
CE mark• Follow the advice in the instructions for use.
• Repairs, maintenances and tests on the device must only be conducted by authorised persons and organisations who
have the know-how and the appropriate instruments and test equipment available. Just owning this service manual
does not entitle to service works.

Medical device• For ordering of spare parts always specify the serial no. of the device. You will find the serial no. on the device and on
the cover sheet of this service manual.
• Only use original spare parts for service works. Spare parts must not be modificated.

Manufacturer• Before opening turn off the device and disconnect it from the local power supply system by unplugging the mains
cable since some device parts are under voltage even when the device has been turned off.
• After service works always inspect the device functions if the service works may have an effect on the safety orfunctioning of the device.

Country of manufacture• If necessary, exchange of single components is explained separately by an instruction for repair, which is delivered
together with the spare part.
• Calibration of inspection equipment has to be performed by the tester himself.

The agitator mechanism incl. the cable AM-CPU serves the agitation of the agitation plate installed in the device during thetempering process. The tilting of the agitator mechanism is generated by a DC servo motor, transferring its motion to theagitator mechanism via a distance bolt. The direction of rotation and the terminal positions of the DC servo motor arecontrolled via a pulse-width modulation signal of the microprocessor on the main board. The microprocessor is connectedto the agitator mechanism via the cable AM-CPU.

Please use the form „Check list for preventive controls“ as documentation of the tests (see Chap. 8)

3.4.2 Warming blower
The warming blower serves the heating and distribution of air inside the device during the tempering process; it is composedof a blower, a flat heating device and the sensor module circulating air. The air temperature inside the device is controlled
via a microprocessor on the main board which continuously measures the air temperature in the suction area of the warming
blower via the sensor module circulating air and controls the flat heating device and the blower. The microprocessor isconnected to the sensor module circulating air via the cable CPU-Air sensors.

RepairWhen ordering spare parts please do always indicate the serial number of the device concerned!
3.4.3 Infrared sensor
The infrared sensor is composed of a Thermopile module incl. an infrared sensor cable, a round frame including the infrared
filter and a screw joint PG7 and serves the contactless temperature measurement of the blood product placed below.
The microprocessor is connected to the infrared sensor via the infrared sensor cable.

5.1

3.4.4 Module Warming plate

5.1.1 Assemblies

During the tempering process the module Warming plate is actively heated. It is composed of an aluminium plate, a built-in
electrical flat heating device as well as the cable heating circuit board-AM with a coding plug at its end. The temperature of
the warming plate is controlled via a microprocessor on the main board which continuously measures the temperature of thewarming plate via a sensor pair in the warming plate and controls the flat heating device. After plugging the cable heating
circuit board-AM in the agitator mechanism, the microprocessor is connected to the sensor pair in the warming plate andthe flat heating device in the module Warming plate via the cable AM-CPU.
3.4.5 Module MAXITHERM
The module MAXITHERM is composed of a folding double plate and a coding plug that is connected with the double plate.
In contrast to the module Warming plate the module MAXITHERM is not actively heated during the tempering process.
3.4.6 Warming plate SAHARA-TSC
The warming plate SAHARA-TSC is actively heated during the tempering process. It is composed of an aluminium plate, abuilt-in electrical flat heating device, the infrared sensor TSC as well as the cable heating cicuit board-AM with a coding plugat its end. The temperature of the warming plate is controlled via a microprocessor on the main board which continuously
measures the temperature of the warming plate via a sensor pair in the warming plate and controls the flat heating device.
After plugging the cable heating circuit board-AM in the agitator mechanism, the microprocessor is connected to the infrared
sensor TSC, the sensor pair in the warming plate and to the flat heating device in the module Warming plate via the cable
AM-CPU.
