HXXXA or HXXXB, where H means Hybrid cable. 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 Sie-
mens 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 sensor.
LXXX are loop cables and are the same for all systems. Loop
cables are installed between the transmitter sensor and the
receiver sensor.

Checklist

Go through the following points before beginning the installa-
tion of the LDS 6 laser gas analyzer to make sure all preparations
are completed.
•
The flanges shall be welded to the wall of the furnace or fun-
nel and properly aligned from both sides.
•
Make sure that the positions of the flanges are stable. The
flanges fitted for the sensors must not deviate more than ±2°.
•
Make sure that the flanges protrude at least 100 mm (4")
from the wall and 0-30 mm (0-1.2") into the furnace or fun-
nel.
•
There must be enough room for the sensors to allow easy
access for maintenance and service.
•
Make sure the path length is measured properly.
•
Make sure that the environment where the central unit is to
be installed have the right temperature conditions.
•
Make sure there is enough space to allow free airflow around
the central unit (500 mm/20" behind, 50 mm/2" above and 30
mm/1.2" below).
•
Make sure the operating and installation temperatures for the
hybrid and loop cables are not exceeded.
