LED Description
LED L = green Left pump head selected
LED R = green Right pump head selected
Before performing a DOCK or PURGE function from the keypad, select
the pump head for which you want to perform the action.
Isocratic pump and quaternary pump
The button is disabled.
DOCK
Pressing the button moves the pistons of the selected pump head to the
appropriate position for maintenance procedures, such as pump head or
piston replacement, and undocks the pistons.
When undocking is complete, the LED next to the FLOW button starts
flashing green for the selected pump head. The LED continues flashing
while no pistons are docked. Pressing the button again docks the
pistons. Docking is complete when the LED stops flashing green.
Note the following:
• To avoid damage to the pump, remove or install the pump heads
only while the pistons are undocked (LED is flashing).
• Before you press the button to undock the pistons, open the purge
valve by turning the valve knob counterclockwise.
• When docking is complete, close the purge valve.
