6 Diagnosis in the event of an error
Table 4
7 Cleaning and storage
A damp cloth can be used for cleaning of the device housing.
Store in a clean, temperature-regulated and dry place!
Error Possible cause Remedial measures
POWER LED does not light up green No input voltage Check voltage supply
No edge detection possible
(
EDGE LED not illuminated)
Working distance too great
Check working distance and adapt as necessary
(section 3.2)
No calibration performed Perform calibration procedure (section 4.1)
Sensitivity not ideal Perform setting procedure (sections 4.3 or 5)
Direction of overlap flow/direction of movement
incorrect
Check settings (section 3.3)
Object to be counted not suitable Test with reference (section 3)
No laser beam ( Caution! Refer to the laser safety
notices in section 8! )
Notify the manufacturer
Edge counting faulty
Sensitivity/calibration not ideal, influence of ambient
light Readjust sensitivity (sections 4.3 or 5) /
repeat calibration procedure (section 4.1)
Error due to multiple pulses
Check pulse width adjustment and readjust /
run
DPA program (recommended) as necessary
Objects to be counted not ideal Test with reference
Sequential speed of edges outside of specification
Check period following object, perform a test at low
speed
The output pulse width can only be
adjusted in minimum range
Incorrect range mode set Switch mode over to desired range (section 4.5)
No output pulse, although EDGE LED is
detecting an edge
Contact problem Check connection cable
Notice!
Faulty results due to changes within the overlap flow with regard to color change, surface structure and edge shape of the
objects to be counted or the distance of the objects from the detector may necessitate renewed calibration and resetting of
the device to the new conditions, and do not necessarily relate directly to malfunctioning of the device.
Attention!
The optics cover (laser beam emission) on the underside of the device may only be cleaned with a non-scratch cloth specially
designed for cleaning lenses (micro-fiber cloth)!
