4.1.10 Module Laser-Diode Operating Hours
The module uses one input word which is consistently transferred via the bus.
Here, the operation hours of the
activated laser diode are output.

5 Causes of Faults and Remedies
The error causes are determined in "Module Error Display", page 21. Depending on
setting the error must be possibly acknowledged for resetting the malfunction code in
the input byte (see "Module Control Bits With Acknowledgement", page 25). If the
switching input was adjusted via the OMSConfiguration Tool-software for error
resetting, the error can be acknowledged also about the external switching input.
Malfunction
Code
Cause Remedy
Bit 0
Intensity error
The device checks
the intensity of the
received laser signal
continuously, it was
detected a below-
minimum intensity.
1. Clean measuring system optics
2. Clean reflecting foil
3. Rule out an interruption of the laser beam
If the possibility of soiling or interruption of the laser signal
can be ruled out, the device must be replaced.
Bit 1
Device temperature
The temperature has
exceeded or fallen
short of the range of
0 - 50°C at the
housing of the device
Appropriate measures must be taken to prevent the device
from overheating or undercooling.
Bit 2
Hardware error
The device has
detected an internal
hardware error.
If the error occurs repeated, the device must be replaced.
Bit 3
Laser diode
switched off
The bit is set, if the
laser diode was
switched off over the
bus, or the switching
input.
Serves only for information purposes.
Bit 4
Intensity warning
The device deter-
mined an intensity of
< 12%.
This message is only a warning and means that the
measuring system optics, or the reflecting foil is to be
cleaned. However, the device operates error-freely
furthermore.
