Identification Of Cables - Siemens LDS 6 Operating Instructions Manual

Preparations for installation
3.3 The hybrid and sensor connection cables
The bending radius of the cable may never be smaller than 100 mm (4"). If clamps are used there
must be a minimum of 0.5 mm (0.02") clearance between cable and clamp or use rubber coated
clamps. Take extra care of hybrid cables for HCl systems since the cables are very sensitive due
to the wavelength used in these systems. The figure below shows the pre-requisites for
installation of the cables.

Identification of cables

All cables are marked with identification tags, as follows:
HXXXA or HXXXB, where H means Hybrid cable, is used for all types of systems. XXX is the serial
number for the cable and A/B depends on the direction in which the cable is oriented. Before
cables are shipped from Siemens they are tested in both directions A to B and B to A. It does not
matter which way the cable is installed. Hybrid cables are installed between the LDS 6 and the
transmitter optics housing.
LXXX are sensor connection cables and are the same for all systems. Sensor connection cables
are installed between the transmitter optics housing and the receiver optics housing.
Make sure the operating and installation temperatures for the hybrid and sensor connection
cables are not exceeded.
