Warnings
Warning signal The object reflects too little light.
Optics dirty
The sensor detects when the optic cover is dirty, and the signal deteriorates 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 drop-
lets, 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.
Errors
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.
Acceleration Sensor (P1PY111, P1PY113)
Acceleration detected
The sensor has detected acceleration above the set threshold via the internal
acceleration sensor.
