ELECTROSTATIC DISCHARGE
CAUTION
The electronic parts of the Analyzer Module can be irreparably damaged if
exposed to electrostatic discharge (ESD).
The instrument is ESD protected when the covers have been secured and safety
precautions observed. When the housing is open, the internal components are
not ESD protected anymore.
Although the electronic parts are reasonable safe to handle, you should be aware of the following considerations:
Best ESD example is when you walked across a carpet and then touched an electrical grounded metal
doorknob. The tiny spark which has jumped is the result of electrostatic discharge (ESD).
You prevent ESD by doing the following:
Remove the charge from your body before opening the housing and maintain during work with opened
housing, that no electrostatic charge can be built up.
Ideally you are opening the housing and working at an ESD - protecting workstation. Here you can wear a
wrist trap.
However, if you do not have such a workstation, be sure to do the following procedure exactly:
Discharge the electric charge from your body. Do this by touching a device that is grounded electrically
(any device that has a three - prong plug is grounded electrically when it is plugged into a power receptacle).
This should be done several times during the operation with opened housing (especially after leaving the
service site because the movement on a low conducting floors or in the air might cause additional ESDs).

Used by Permission
1. Never drop cylinders or permit them to strike each other violently.
2. Cylinders may be stored in the open, but in such cases, should be protected against extremes of weather
and, to prevent rusting, from the dampness of the ground. Cylinders should be stored in the shade when
located in areas where extreme temperatures are prevalent.
3. The valve protection cap should be left on each cylinder until it has been secured against a wall or bench,
or placed in a cylinder stand, and is ready to be used.
4. Avoid dragging, rolling, or sliding cylinders, even for a short distance; they should be moved by using a
suitable hand-truck.
5. Never tamper with safety devices in valves or cylinders.
6. Do not store full and empty cylinders together. Serious suckback can occur when an empty cylinder is
attached to a pressurized system.
7. No part of cylinder should be subjected to a temperature higher than 52 °C (125 °F). A flame should never
be permitted to come in contact with any part of a compressed gas cylinder.
8. Do not place cylinders where they may become part of an electric circuit. When electric arc welding,
precautions must be taken to prevent striking an arc against the cylinder.

ANALYZER SYSTEM ARCHITECTURE
The NGA 2000 CLD is available as a "stand-alone analyzer" or as a "blind" Analyzer Module (AM). The CLD
analyzer module can be part of the stand-alone analyzer
or a component of an analyzers system (Fig. A-1).
The NGA 2000 system made it possible, to configure
the CLD as a flexible "stand-alone analyzer" consisting
of a CLD "Analyzer Module", a Platform (complete with
front panel display/operator interface), and input/output
(I/O) modules.
The “analyzer module” is a “blind” analysis unit but retains all the advanced design features. The AM variant
is designed for integration as part of a NGA 2000 analysis system or special customer developed networks.
The platform/MLT´s front panel can act as operator interface for a stand-alone analyzer or as the a central
interface for multiple Analyzer Modules. In multi analyzer systems, this feature eliminates duplication of the
display/operator interface. In addition to the obvious operational benefits there are significant cost and system
packaging advantages not possible with conventional
analyser configurations.
This flexible network communication architecture is
shown in the schematic of Fig. A-2.
