12.1 Error indications in the display
Display
Possible cause
Solution
Profile X
Sensor running in standard mode. There is no
failure.
No need for action.
Object out of range
Object is outside the operating range (too far /
too close).
No height profile and matching value can be
determined.
Enlarge the distance to the object. The
detected profile must be in the operating range
150...300 mm.
Short circuit at OU1
Short circuit at switching output 1.
Check the wiring.
Short circuit at OU2
Short circuit at switching output 2.
Check the wiring.
Laser off
Laser was switched off by user.
Switch on the laser.
(Pin 5 / IO-Link / iVA)
No active profile
A free memory location was activated via IO-
Link.
Activate an occupied memory location.
---
No active profile selected
Activate a reference profile. Parameter level
basic functions (
If [Profile source select] = [PDout]:
Activate a reference profile via IO-Link or the
ifm parameter setting software. This is
indicated by [Remote] in the display.
12.2 Error indications in the “Vision Assistant” software
Display
Possible cause
Solution
Low amplitude
The data points of the detected laser line have a
very low intensity.
All data points (352) are concerned:
• Object is outside the operating range or is
extremely dark.
u
Check the distance to the object.
If only a few data points are concerned:
• Object features large differences in
luminosity.
• Due to the characteristics of the object, some
of the reflected laser beams do not reach the
receiver.
u
Change the position of the sensor or the
object.
High amplitude
The data points of the detected laser line have a
very high intensity.
In case of a fixed integration time:
u
Reduce the time or change the setting to
[Auto].
In case of large differences in luminosity:
u
Change the position of the sensor or the
object.
Multiple lines
Laser line is too thick due to:
• translucent surfaces such as skin or rubber
• multipath propagation on shiny surfaces
u
Enlarge the distance to the object.
u
Change the position of the sensor or the
object.
Sensor receives several reflections due to:
• semi-transparent objects, laser line is
reflected at two planes
• shiny surfaces on sharp profiles
u
Change the angle of incidence. If possible,
darken the background.
u
Change the position of the sensor or the
object.
Too near / far
Data points outside the operating range in Z
direction (< 150 mm, > 300 mm)
u
Place the object within the operating range
(150...300 mm).
