The test will check the valve in the open position rst, and then in the closed 3.
position. If the valve fails the test, contact CEM Service for troubleshooting help.
Test Rotary 2
Select Test Rotary Valves and then double-click on Test Rotary Valve 2 in the 1.
Test window.
A warning box will pop up stating that a centrifuge tube should be connected to 2.
position 1 on the product manifold. Ensure a tube is connected and properly
sealed and then click OK to continue the test.
The test will check the valve in the open position rst, and then in the closed 3.
position. If the valve fails the test, contact CEM Service for troubleshooting help.
Test Rotary 3
Select Test Rotary Valves and then double-click on Test Rotary Valve 3 in the 1.
Test window.
The test will check the valve in the open position rst, and then in the closed 2.
position. If the valve fails the test, contact CEM Service for troubleshooting help.
Internal, Nitrogen, and Liquid Delivery Tests
There are three types of delivery tests available in Test System: Internal Delivery, Nitrogen
Delivery, and Liquid Delivery. Each category corresponds to a specic ow path within the
Liberty, and each contains individual tests of each valve in that path. The delivery tests are
intended to test the function of each valve on the system.
There are three categories of Internal Delivery tests: the RV valves, the M valves, and the EN/EX
Valves. There are three categories of Nitrogen Delivery tests: the P valves, the PE valves, and
the R valves. There are two categories of Liquid Delivery test: the L valves and the LE valves.
Setting Up the Liberty for a Delivery Test
Before beginning a delivery test, certain precautions need to be taken to ensure accurate test
results:
Remove all reagents (amino acids, external amino acids, activator, activator 1.
base, cleavage, deprotection, capping, Main Wash/DMF, Secondary Wash/DCM)
from the system.
Remove the dip tube lters from all dip tubes.2.
Perform a backpurge on all positions to ensure the lines are free of liquid. 3.
Loosen or remove any bottles connected to the reagent positions (amino acids, 4.
external amino acids, activator, activator base, cleavage, deprotection, capping,
Main Wash/DMF, Secondary Wash/DCM).
