This menu enables the user to test and to adjust the Sample Valve ball alignment with the Sample Valve
ports.
1. Test First Failure. When Test First Failure function is activated, BioTector rotates the sample valve from
sensor position 1 (SEN1) to sensor position 2 (SEN2) and to sensor position 3 (SEN3) automatically to
identify the adjustment points, where the position of the valve is no longer detected at each sensor (i.e.
when the first failure of the detection of the valve position occurs). The adjustment points are small time
increments, implemented by the software, which delays the stopping of the ball valve and thus the
physical stop position of the ball valve.
Loop Count:
Currently Testing:
First Failure Point:
When the test is completed, a "COMPLETE" message is displayed at the bottom of the screen.
3. Adjust Sample Valve. Adjust Sample Valve function allows the user to manually adjust the sample valve
stop position to align the ball valve with the valve ports. When the adjustment values are entered in this
menu, system displays the CURRENT VALVE POSITION (e.g. SEN1, SEN2 etc.). Follow the procedures
and on screen instructions. If the adjustment values entered are too high, system displays an "INVALID
ADJUSTMENT VALUE, VALUES HAVE TO BE 5 POINT BELOW FIRST FAILURE" warning with the
latest first failure values for all sensor positions if it is available in the system. If the first failure values
displayed below this warning is 0, 0, 0, run the TEST FIRST FAILURE above and when the test is
complete, enter the adjustment values accordingly.
The procedures described in information sheet "M046. Sample Valve Adjustment and Sample Tube
Positioning Guidelines" should be followed when the sample valve is replaced. This document is available
inside MMC/SD card shipped with the BioTector.
In the event of a 17_SMPL VALVE NOT SYNC fault in the system, refer to information sheets "T018.
BioTector Sample Valve Not Synchronized Fault Troubleshooting after Valve Replacement" and "TT002.
BioTector Sample Valve Not Sync Fault_Quick Troubleshooting", which are available inside MMC/SD
card shipped with the BioTector.

Loop Count displays the number of loops (2 by default) the valve is rotated
for each adjustment point for each sensor position during the test.
Currently Testing displays the adjustment points (the time delay implemented
by the software) for each sensor during the test. The adjustment points are
from 0 (minimum) to 15 (maximum) with 1 point increments.
First Failure Point displays the adjustment point at which the system fails to
detect the position of the valve.
