Operating instructions
Movements for distribution valves (3-way with U11 config;
and 6-way)
The commands below apply to two distribution valves:
• The 3-way distribution valve when configured with the U11 command
• The 6-way distribution valve
For these valves, the distribution ports are numbered from the left or right,
depending on whether the Z or Y initialization preceded the positioning
commands.
• After Z initialization: ports are numbered from left to right (clockwise).
• After Y initialization: ports are numbered from right to left (counter clock-
wise).
Ports are numbered 1 through 3 for the 3-way distribution valve, and 1
through 6 for the 6-way distribution valve.
Refer to Figure 5-14 and Figure 5-15 to view valve positions vs. commands.
Move valve clockwise to specific distribution port (I<n>)
The [I]<n> command moves the distribution valve to port <n> in a clockwise
motion.
Example: I<2> moves valve to distribution port 2.
Movement is the same regardless of Z or Y initialization.
Move valve counterclockwise to specific distribution port (O<n>)
The [O]<n> command moves the distribution valve to the port <n> in a
counterclockwise motion.
Example: [O3] moves valve to distribution port 3.
Movement is the same regardless of Z or Y initialization.
CAUTION:
Due to the smaller internal port diameters of the 6-way
distribution valve, it is recommended that fluid velocity does not exceed 1500
µ
L/sec when using this valve. Use caution when setting velocity with 2.5 mL and
larger syringe sizes, to avoid cavitation and excessive syringe back pressure.
Refer also to "Calculating flow rates" (page 127).
<n> 1…X assigned port, where X = number of distribution ports on valve,
and therefore the highest-numbered port. The syringe port is
excluded from the count. For a 3-way valve X=3, and for a 6-
way valve X=6.
0 Sets valve to port 1.
