What if the sensor is not outputting a signal?

Check the green LED on the Signal Processor Unit.
If it is illuminated while the vehicle is moving, this indicates that the sensor is in standstill mode. Check the following:

Cycle power to the sensor.

Is the Sensor is mounted within the nominal working range?
If not, adjust the mounting to specification.

Are the Sensor lamps bright and providing ample illumination?
If not, replace as needed.

Are the Sensor optics obstructed?
If so, clean the protective lens and/or mount the Sensor so that no vehicle or other components obstruct the optical path between the Sensor and the test surface.

What if I have signal problems when testing on dark surfaces?

1. Check the halogen lamps for proper illumination (see above).
2. Reduce the Sensor mounting height.
3. Check to be sure the optics are not obstructed (see above).

If these solutions do not address your issue, please contact CORRSYS-DATRON for technical support.

What if I have problems on wet surfaces?

Mount the sensor on the front of the vehicle to avoid excess spray that can obstruct the optic. For aquaplaning testing and other wet-surface applications, CORRSYS-DATRON now offers the new CORREVIT® Aquaplaning Sensor.

Does it matter if the Sensor is mounted in a longitudinal direction (perpendicular to the vehicle bumper/direction of travel) or a transversal orientation (parallel to the bumper/direction of travel)?

As delivered, each CORREVIT® Optical Sensor is configured for operation in either a longitudinal direction or a transversal orientation. This configuration can be changed if required. An internal adjustment must be made by a Certified CORRSYS-DATRON Service Engineer in order to change the Sensor orientation.

Please contact your CORRSYS-DATRON Service Representative for information.

NOTE: When ordering a CORREVIT® Optical Sensor, please specify the required orientation.

How do I correct the angle if the sensor was mounted with an angle deviation?

1. Check the bubble level in both axes to assure proper Sensor mounting.
2. Be sure that the current angle offset via CeCalWin Software does not indicate an offset.
3. Make a calibration run as describedon pages 49 - 58 in the CeCalWin user manual.

Do I need to calibrate the sensor to the test surface?

Sensor factory calibration guarantees ±0.2% maximum deviation. If you require maximum deviation of ±0.1%, you can calibrate your sensor to the test surface.

1. Enter a known distance into CeCalWin.
2. Click Start to begin the test run over a known distance (as determined by measurement tape, etc.).
3. Stop the measurement as soon as the known distance has been attainted.

Complete calibration details are available in the Sensor and CeCalWin user manuals.
