System and Checksum Tests
The information from the System and Checksum Tests is important if
you need to contact Bio-Tek.
The
System Self Test and Checksum Test are performed automatically whenever
the washer is powered on. They can also be run manually via the washer’s keypad.
System Self Test
The System Self Test checks the vacuum (when run manually), manifold, and
manifold-to-carrier positioning.
For the Magna , a magnetic carrier test is also performed. This test moves the
magnet holder to the extreme left and most vertical position and then back to
home where a “position verify” command is executed. If the magnet holder loses
steps when making these moves, the “position verify” will generate an error code,
failing the test.
To run the System Self Test:
At the Main Menu, select
UTIL TESTS SELFCHK
.
The following screen will appear while the test is running:
SYSTEM TEST RUNNING. . .
PLEASE WAIT. . . .
If the test passes , the Main Menu will be displayed.
If the test fails , the washer will beep repeatedly and the display will show an
error code. If this happens, write down the error code and then press the Stop key
on the keypad to stop the beeping. Look up the error code in Appendix B, Error
Codes
, to determine its cause. If the problem is something you can fix, turn off the
washer, fix the problem, and then turn the washer back on. If the cause is not
something you can fix, contact Bio-Tek’s Technical Assistance Center.
