9.2.6 Ethernet connection socket (MAGDOS LP-Net only)
Fig. 9-3: Ethernet connection socket
The network connection socket makes it possible to control the stroke
frequency and the number of strokes. In addition, it is possible to
transmit in the opposite direction all the disturbance and status
messages.
The dosing pump has a network input in the form of a 4-pole, D-coded
M12x1 female connector. To make the typical Ethernet RJ-45 male
connection, Lutz-Jesco GmbH offers different lengths of special twisted-
pair network cables. If you use third-party cables, choose a Category 3
cable with an impedance of 100 Ohm or above.

9.2.6.1 Installing a wired network
During installation, observe the following points:
The Ethernet is cabled in a star topology. The maximum cable length
is 100 m.
You must route separately as a bundle the different categories of
cables (e.g. power supply, data lines and sensitive lines for meas-
uring purposes). In this connection, cables should cross at an angle
of 90°.
There must either be a minimum distance between the power cable
and data lines of 10 cm or you must install a partition or route the
data line in a metal pipe. If this is not possible, use separate cable
support systems.
Only use screened cables and plug-in connectors.
Route copper wires outside cable support systems through plastic
pipes.
Temperatures that are too high or too low result in lower mechanical
and electrical loading or lead to damage.
Data lines must only be subjected to a defined tensile load; other-
wise, the electrical or attenuation values can no longer be guaran-
teed.
When pulling cables out of the cable drum, avoid looping or pulling
over sharp edges.
With copper wires, implement potential equalization; when doing
this, differentiate between hazardous and non-hazardous areas.
Electrical, magnetic and electromagnetic fields affect signal trans-
mission and under some circumstances can destroy electronic
components.
