Carousel Position error (service)

E18 is the error code for Carousel position error. Starrsed was not able to position the carousel. There was a difference found in the pipette memory position table and the actual measured position of the position sensor.

A position error can occur if the Starrsed is switched OFF while the carousel is moving to the next position or when the Rinse nozzle sticks up.

Warning: It is highly recommended to wash all samples after a position error due the fact the linked pipette number (patient data) is not the same as before the position error!
