Troubleshooting and Test Functions
Motor Temperature
Motor Temperature
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 “Transport Assembly” on page 210 for motor identification.
Motor 0 temperature : X-axis motor.
Motor 1 temperature : Z-axis motor.
Motor 2 temperature : Theta (gripper rotation) motor.
Motor 3 temperature : Gripper motor (motor for gripper fingers).
The processor monitors the current drawn by each motor and the time the
motor is drawing current. The current drawn by the motors is dependent on
the load on each motor (friction, mass of components etc.). If the current
drawn is too high, or the time the motor draws current is too long, the error
message is generated.
Probable Causes
• Mechanical obstruction.
• High friction in the transport assembly.
• Motor belt tension too high.
• Defective motor.
• Defective transport assembly flex board.
Suggested Actions
❏
Switch off the autosampler at the power switch. Wait at least 10 minutes
before switching on again.
❏
Ensure unobstructed movement of the transport assembly.
❏
Exchange the transport assembly.
