Cause of error
Tube is not closed properly.
Sample is jammed between the cap and the
tube and damages the seal. This might cause
liquid to run trough the seal.
Tube seal is leaky.
Sleeve is worn.
Inappropriate sample material.
If the motor is blocked due to a high
resistance of the sample material, the
instrument will try three times to get started
again.
If the blockage can be resolved, the
instrument will continue the run of the
program. If the blockage cannot be resolved,
the program will automatically be aborted.
Tube is not correctly fitted into the snap-fit of
the Trough.
Tube is not closed properly.
The duration of the program exceed 3,200
rounds per run (rpr). It is not recommended
to run programs exceeding this limitation!

commands that shall be
iterated.
