The port is set to 10001 at the factory. You must use the same numbers
in the device configuration of the chromatography software as in the device,
otherwise the connection fails.

Ground
Electronic defect
Electronic hazard when using an identically constructed power adapter from
another manufacturer.
Contact the Technical Support of KNAUER.
Never connect the device to the power connection.
The ground connection for the pump has a designated hole with a thread M3
on the back of the device.
If the supplied power adapter is used, then the ground connection remains
unused.
Please contact the technical support of KNAUER, if the pump along with
other devices should be connected to the power supply with a 6-prong
power adapter; a pump needs to be grounded exclusively.

Switching on the Pump
Prerequisite:
In analog control mode, close the contact between GROUND and
START IN before starting the pump.
Component defect
Damage to the pump head in case it runs dry.
Ensure that liquid runs through pump head and piston backflushing.

1. Connect the power adapter
to the power supply.
