The Hall sensor did not signal the zero position over more than 5 revolutions

Occurs if the Hall sensor fails to signal the zero position of the CAM of the pump motor for more than five revolutions. The zero position is the home position of the pump (i.e., the reference point as it rotates around a fixed axis).

The Hall sensor reported an impossible zero position

Occurs if the Hall sensor reports a mismatch between the pump motor rotational counts and the CAM rotations. The zero position is the home position of the pump (i.e., the reference point as it rotates around a fixed axis).

This may indicate a calibration error in the CAM position or physical damage to the encoder on the pump mechanism.

If the injection valve fails to switch position within 1 second of being toggled, the instrument control firmware reports an error to Chromeleon CDS and this error message appears.

The inject valve is disconnected

Occurs when the injection valve cannot be detected.

The leak sensor is wet

The leak sensor is installed in the drip tray located near the bottom of the component panel. This error occurs when liquid accumulates in the drip tray.

The low pressure valve 1 is disconnected

The low pressure valve 2 is disconnected

Occurs when the low-pressure valve cannot be detected.

Motor power failure detected

This error occurs when the pump motor fails.

This typically occurs when the system power is turned off while the pump is running. You may also notice a significant pressure transducer offset.
