Movements for 4-port loop valve
The following commands apply to the 4-port loop valves (see "Valve selec-
tion information" (page 46).
In this configuration the four ports are referred to as left, right, top, and
syringe. Refer also to Figure 5-16 (page 58), which shows valve positions
according to valve movement and initialization commands for the 90° 4-
port loop valve.
With [Z] initialization the valve rotates 90° CW when transitioning from [I],
to [E], to [O], and to [B]. With the [Y] initialization the valve rotates CCW in
the same valve position sequence.
Move loop to input position (I)
The [I] command moves the valve to the input position. The input position
will be different depending on whether the [Z] or [Y] initialization command
was sent first.
• After Z initialization: connects left port to syringe, and top port to right port.
• After Y initialization: connects top port to right port, and left port to syringe.
Move loop to extra port (E)
The [E] command moves the valve to the extra position. The extra position
is the same for either the [Z] or [Y] initialization command.
• Connects left port to top port, and right port to syringe.
Move loop to output position (O)
The [O] command moves the valve to the output position. The output posi-
tion can be either to the left or the right depending on the [Z] or [Y] initial-
ization commands.
• After Z initialization: connects top port to right port, and left port to syringe.
• After Y initialization: connects left port to syringe, and top port to right port.
Move loop to bypass position (B)
The [B] command moves the valve to the bypass position. The bypass posi-
tion is the same for either the [Z] or [Y] initialization command.
• Connects right port to syringe, and left port to top port.
