optoNCDT ILR 1183
9. Malfunctions, Troubleshootings
9.1 Malfunctions
Defaults Cause Action for removal
No data coming via Profibus Faulty Profibus configuration Check Profibus configuration
Device error
(Ext. diagnosis)
Hardware problems
Reship sensor for repair, contact technical
support
9.2 Troubleshootings via Profibus
Code Cause Action for removal
E15 Excessively poor reflexes Use target board, observe minimum requirement
on measuring distance (> 0.1 m)
E16 Excessively strong reflexes Use target board
do not measure against reflecting surfaces
E17 Too much steady light
(for example sun)
Mount sensor in such a position that excessive incidence of
steady light is prevented, extend glare protection tube, pro-
vide additional light-shielding, for example protective cap
E18 Only in DX mode: too much difference
between measured and pre-calculat-
ed value
Check path from distance meter to target being measured
for obstacles
E23 Temperature below –10 °C/ +14 °F Provide ambient temperature > -10 °C/ +14 °F
E24 Temperature above +60 °C/ +140 °F Provide ambient temperature < +47 °C/ +116.6 °F
E31 Faulty EEPROM checksum, hardware
error
Service required if fault occurs repeatedly
> Reship sensor for repair
E51 Failure to set avalanche voltage
1. straylight
2. hardware error
1. Check target reflectance and ambient light
(steady light), make sure that neither target not entry open-
ing of sensor is exposed to light from reflecting surfaces,
projectors or sun
2. Service required > reship for repair
