. The Dimension Icon stage controller will produce a high-pitched noise if it is tilted more than 45 degrees. There are mechanical pumps that need to be kept level in order to properly work.
The Dimension Icon stage controller alarm will also sound if the internal temperature exceeds 40°C. The illuminator inside the controller can cause the inside temperature to rise beyond this point if the ventilation to the controller is restricted. The air inlet screen on the front of the controller may become clogged in a dusty environment.
Illuminator port timed out: The serial port connected to the Dimension Icon stage controller is not connected or is not communicating properly.
Stage not initialized: The serial port connected to the stage is not connected or is not communicating properly.
Stage controller error: The serial port connected to the stage is not communicating properly.
Illuminator Error, Manual override is on: The manual control on the front of the stage controller is being used. Turn the illuminator manual control knob counter-clockwise until a click sound is heard, indicating that it is switched off.
Bad data read from illuminator was 0,S.B. 80: The stage controller power is off or the power supply inside the stage controller is not working.
Warning focus position not updated: You tried to move X-Y stage with no AFM SUM signal.
Safety check failed SUM too low: There are 2 explanations for this message:
The focus axis is at its limit: The focusing objective is either fully extended or fully retracted. This message will appear during the locate tip routine.
Warning: Sample clearance reduced! Unable to move past limit: The focusing objective reached the extended limit when moving to the locate tip position. This can happen during STM use due to the lower tip location. The end of the STM probe should protrude no more than 1 mm below the end of the probe holder tube. This message can also occur if the sample clearance is set to a very large value. The standard sample clearance distance is 1000 µm.
Motor axis is at limit: The SPM (Z stage) is fully retracted. This can happen after the stage is initialized. Ignore the message and lower the Z stage by using the Focus Surface controls.
The tip location has been changed to an unsafe distance. If you proceed with this change you will need to re-teach the tip replacement position: This warning appears during the Locate Tip routine if the focusing objective has moved more than 300 µm from the previous tip focus position. This is common when switching between silicon and silicon nitride cantilevers due the thickness difference of their substrates. The message will also appear when switching between AFM and STM probes. The intent of this message is a safety check to warn you that you have moved the objective unusually long distance. Select OK if you’ve changed to a different style of probe.
