Troubleshooting
Code Description
Action for removal
E15
Excessively poor reflexes; Distance sensor
(Front edge) against target < 0.1m
Use target board,
increase distance between sensor and target.
E16
Excessively strong reflexes
Use target board.
E17
Too much steady light (for example sun)
Reduce ambient light at target;
reflecting objects remove or cover.
E18
Only in DX mode (50 Hz): too much differ-
ence between measured and pre-calculated
value
Check path from distance meter to target being
measured for obstacles.
E19
Only in DX mode (50 Hz):Target motion
speed > 10 m/s
Reduce motion speed of target respectively of the
sensor.
E23
Temperature below -10 °C
Provide ambient temperature > -10 °C
E24
Temperature above +60 °C
Provide ambient temperature < +60 °C
E31
Faulty EEPROM checksum,
hardware error
Service required if fault occurs repeatedly
--> reship the sensor for repair.
E51
Failure to set avalanche voltage of diode laser
1. straylight or
2. hardware error
1. Check ambient light radiation; limit ambient light
2. Service required --> reship the sensor for repair.
E52
Laser current too high / laser defective
--> Reship the sensor for repair, contact technical
support
