Missing Wash Vial

Error ID: 4035, 4542, 4707
The wash vial programmed in the method was not found.
When the gripper arm picks a vial out of the sample tray, the processor
monitors the gripper motor encoder. If a vial is present, the closing of the
gripper fingers is limited by the vial. However, if no vial is present, the gripper
fingers close too far. This is sensed by the processor (encoder position),
causing the error message to be generated.

Motor Temperature

Error ID: 4027, 4040, 4261, 4451
One of the motors of the transport assembly has drawn excessive current,
causing the motor to become too hot. The processor has switched OFF the
motor to prevent damage to the motor.
See figure
• Motor 0 temperature: X-axis motor.
