Operating instructions
Movements for distribution valve (3-way with U4 config)
The following commands apply to the 3-way distribution valve as it behaves
when set with the U4 EEPROM configuration command (see "Valve selec-
tion information" on page 46.)
In this configuration, the three distribution ports are referred to as left, right,
and top. See Figure 5-13 for valve positions vs. commands.
Set syringe to left/right port (I)
The [I] command sets the syringe to either the left port or the right port,
depending on Z or Y initialization. The positioning is opposite that of the [O]
command.
• After Z initialization: connects syringe to left port.
• After Y initialization: connects syringe to right port.
Set syringe to right/left port (O)
The [O] command sets the syringe to either the right port or the left port,
depending on Z or Y initialization. The positioning is opposite that of the I
command.
• After Z initialization: connects syringe to right port.
• After Y initialization: connects syringe to left port.
Set syringe to top port (E or B)
The [E] and [B] commands both connect the syringe to the top port. Their
use is interchangeable.
Movement is the same regardless of Z or Y initialization.
