Valve to Mainpass Failed

Error ID: 4015
The injection valve failed to switch to the mainpass position.
The switching of the injection valve is monitored by two microswitches on the
valve assembly. The switches detect the successful completion of the valve
movement. If the valve fails to reach the mainpass position, or if the
microswitch does not close, the error message is generated.

Vial in Gripper

Error ID: 4033
The gripper arm attempted to move with a vial still in the gripper.
During specific stages of the sampling sequence, no vial should be held by the
gripper. The autosampler checks if a sample vial is stuck in the gripper by
closing and opening the gripper fingers while monitoring the motor encoder. If
the gripper fingers are unable to close, the error message is generated.
