Maintenance Functions

Some maintenance procedures require the needle arm, metering device, and
needle carrier to be moved to specific positions to enable easy access to
components. The maintenance functions move these assemblies into the
appropriate maintenance position. In the ChemStation the sampler
maintenance positions can be selected from the Maintenance menu in the
Diagnosis display. In the Control Module the functions can be selected in the
Test screens of the well-plate sampler.

Maintenance functions

The maintenance functions moves the arm assembly in a specific position in
order to enables easy access for maintenance operations
Home Position
The "home position" function moves the arm to the right side for better access
and exchange of the trays
Park position
The "park position" function moves the arm to the left side of the tray. In this
position it is possible to secure the sample transport mechanism with the
protection foam.The sample transport is than ready for transporting.
Change Piston
The "change-piston" function draws the piston away from the home position,
relieving the tension on the spring. In this position, the analytical head
assembly can be removed and reinstalled easily after maintenance. This
position is also used to change the analytical head plunger and metering seal.
