Installation; Pressure Equipment Directive, 97/23/Ec - Siemens SITRANS LG200 Series Instruction Manual

Installation

WARNINGS:
• Installation shall only be performed by qualified personnel and in
accordance with local governing regulations.
• SITRANS LG200 is to be used only in the manner outlined in this
manual, otherwise protection provided by the device may be impaired.
• Never attempt to loosen, remove, or disassemble process connection
or instrument housing while vessel contents are under pressure.
• The Model 7ML1301-2, 7ML1301-4 or 7ML1301-6 overfill probes should
be used for Shutdown/Overfill applications. All other Guided Wave
Radar probes should be installed so the maximum overfill level is a
minimum of 150 mm (6") below the process connection. This may
include using a nozzle or spool piece to raise the probe. Consult factory
to ensure proper installation.
• Materials of construction are chosen based on their chemical
compatibility (or inertness) for general purposes. For exposure to
specific environments, check with chemical compatibility charts
before installing.
• The user is responsible for the selection of bolting and gasket materials
which will fall within the limits of the flange and its intended use and
which are suitable for the service conditions.
• Improper installation may result in loss of process pressure.
Notes:
• For European Union and member countries, installation must be according to ETSI
EN 302372.
• Refer to the device nameplate for approval information.

Pressure Equipment Directive, 97/23/EC

Siemens Milltronics level transmitters with flanged, threaded, or sanitary
clamp type process mounts have no pressure-bearing housing of their
own and, therefore, do not come under the Pressure Equipment Directive
as pressure accessories, (see EU Commission Guideline 1/8).
