8.5.2 Warning/Error Output Function
The status messages used to trigger the collective message can be defined for the warning output and
the error output respectively. The status messages are OR-linked so that the output is activated when one
of the defined status messages is activated.
Function Possible Settings Default
Warning output See table “Status Messages” Signal warning, optics dirty, am-
bient light, temperature too
high, temperature too low, un-
dervoltage, interference in the
working range
Error output See table “Status Messages” Object too close, object too far,
no signal, device error, over-
temperature, short circuit
Status Messages
Warnings
Warning signal The object reflects too little light.
Optics dirty The sensor detects when the optic cover is dirty, and the signal dete-
riorates as a result.
Ambient light Object detection is impeded by too much ambient light.
Interference in the working range When using the interference filter, the sensor detects whether a brief
interfering event has occurred in the measuring range. This could be
chips, water droplets, etc., for instance.
Temperature too high The sensor’s internal temperature is too high.
Temperature too low The sensor’s internal temperature is too low.
Undervoltage The supply voltage is too low.
Device warning An internal device error has occurred.
Emitted light off The sensor’s emitted light is switched off.
Error
No signal The sensor is not receiving a signal.
Object too close The object is below the setting range or the set measuring range.
Object too far The object is above the setting range or the set measuring range.
Short circuit A short circuit has occurred on at least one pin.
Over-temperature The over-temperature has been exceeded. To protect the emitting
unit, the laser is switched off.
Device error A hardware error has occurred. For safety reasons, the laser is
switched off.
Speed measurement
Overspeed detected The sensor has detected a speed above the set threshold via the in-
ternal speed measurement.
