Description
Turns off the syringe detection if the sensor fails or if a special
syringe with unknown ID is installed. Turning the syringe
identification sensor off displays a dialog box for selecting a
syringe identification.
Provides the choice of referencing all axes at the start of the system
or suppressing the referencing. Use this function to detect a
possible loss of steps.
Turns off the automatic recovery of the PAL System after
detecting a collision (loss of steps of a stepper motor).
Stop XY Error = ON: Automated recovery turned OFF
Stop XY Error = OFF: Automated recovery turned ON
If recovery is turned off, the PAL System always checks its position
before moving to the injection port for injection. This can result
in an extra move, crossing over the x-y-axes sensors, if the injection
port is at the opposite end of the x axis relative to the sample
location, (zero x-axis position in between sample location and
injection port).
For critical application fields (for example, clinical analyses), turn
off the automated recovery; Stop XY Error= ON.
Monitors the plunger travel path to ensure that the plunger tip
reaches the syringe zero point in all cases as compared to the
original plunger referencing and defining the syringe zero point. If
an error is detected, the PAL System stops. This feature is useful if:
sample solutions with particles need to be handled, the syringe
type is not adequate for the solution composition, or the syringe
plunger is blocked or bent.
Changes a syringe using the Chnge Syr menu function and moves
the plunger up to the position specified by this item. For normal
use, accept the default values.
