Park Arm (Park Gripper)
CAUTION Before transporting or shipping the autosampler, always secure the arm in the
park position.
In order to prevent mechanical damage to the transport mechanism during
transport, the gripper arm should be moved into the park position. The park
arm function moves the gripper and transport slider to the home position
behind the sampling unit, and lowers the gripper arm into the park position
where the transport assembly is secured against a mechanical stop. The
autosampler can be switched off after parking the arm.
NOTE Before parking the gripper arm, ensure there is no vial in the gripper. Use the
“Release Gripper” function to remove the vial.
