2.6_CA-EN_03
After the machine is switched on, the system initiates a series of hardware self-tests. For these tests, no
disposable material (solution bags, lines) must be installed on the machine.
Numeric Test
This test displays the numeric strings (0 1 2 3 4 5 6 7 8 9) in the three different fonts which the machine has
available. The user has to check whether the sequence is correct.
If one of the self-tests fails, a relevant warning is displayed. In this case, ensure that the machine is in the
initial state. Then another self-test can be performed after correction of the cause of the error by selecting the
<
Retest
> menu item in the menu bar and pressing the
key.
When the hardware tests and the numeric test have been successfully completed, the Start screen is displayed
by selecting the <
End
> menu item in the menu bar and confirming with the
key.
LED Test
During the execution of self-tests, the hardware performs self-tests of the LEDs by switching them on
intermittently:

key.
The user must make sure that all LEDs operate correctly.
T0 tests
The T0 tests are performed continuously and periodically over the complete operating period of the machine.
Static T1 tests
The static T1 tests are performed after the machine is switched on. The therapy can be started only when all T1
tests were performed without error.
Dynamic T1 tests
Dynamic T1 tests are performed during the priming and rinsing phase to ensure the correct installation of the
lines.
The system performs various dynamic self-tests during the priming and rinsing phase to ensure the
functionality of the following units:
Load cell
Blood leak detector (BLD)
Dialysate air detector (DAD)
Venous air detector (SAD)
Arterial pressure (PA)
Plasma prefilter pressure (PBE) and venous pressure sensors (PV)
Pumps
Heating
The temperatures of the dialysate measured by the controller and the supervisor, respectively, are
compared.
