Lock the catch hooks with the rail. Press gently on grommet one more
time.
4.3 Fiber Optic / RJ45 Ethernet Converter
The Fiber Optic / RJ45 Ethernet Converter assures high reliability and stability in harsh environments, making it a
robust bridge between enterprise fiber-optic backbones and Ethernet devices like the linescanner. Using fiber
optics, you prevent electrical interference from corrupting the CS400 system. The Fiber Optic / RJ45 Ethernet
Converter supports fast speed and high distance transmissions. Copper based Ethernet communication is very
limited in length without using a repeater.
The Fiber Optic / RJ45 Ethernet Converter in the system connection box is converting up to 4 Ethernet channels
to support one or two scanners and the CS400 accessories. The Fiber Optic / RJ45 Ethernet Converter in the
control room is converting the glass fiber signals back to TCP/IP Ethernet again. For further technical details see
appendix 9.3
Fiber Optic / RJ45 Ethernet Converter , page 62.
4.4 Position Indicator
The position indicator is a temperature resistant inductive proximity switch used to synchronize the scanning
system with the kiln rotation.
Figure 4-6: Position Indicator
The position indicator consists of two parts, a high temperature sensor head, and a junction box. Since the
maximum ambient temperature allowed is 230°C (446°F), the sensor may be mounted near the kiln’s surface. For
the junction box a maximum ambient temperature of 70°C (158°F) is allowed. For further technical details see
appendix 9.5
Position Indicator , page 65.
Both components, sensor and junction box, are connected via a high temperature cable (length: 5 m / 15 ft).
Protecting the cable against mechanical stress is recommended. Since the position indicator is necessary to
generate a trigger pulse for the CS400 system, a trigger bar must be welded onto the colder end of the kiln and if
possible close to the drive ring (see the figure below).
The distance between the trigger bar and the position indicator is a very important parameter for correct operation.
If the distance is too small, the trigger bar can destroy the sensor head. On the other hand, if the distance is too
big, the position indicator will be unable to detect the trigger bar. Thus, it will not be able to generate the trigger
pulse for the system.
Note
In the case of a non-existing trigger signal, the system switches to the non-synchronized mode. The non-
synchronized mode is indicated in the software, thermograms are not recorded!
Note
In multi-scanner systems, the trigger signal may be associated with any scanner!
