Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury
may
result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.
Qualified Personnel
The product/system described in this documentation may be operated only by
personnel qualified
for the specific
task in accordance with the relevant documentation, in particular its warning notices and safety instructions.
Qualified personnel are those who, based on their training and experience, are capable of identifying risks and
avoiding potential hazards when working with these products/systems.

Purpose of this documentation
This documentation contains all the information you need to operate the device using the
local user interface (LUI).
The LUI consists of a display and keyboard with four keypads with which all analyzer
functions can be set using menus.
The analyzer can also be operated with SIMATIC PDM. Additional information on this topic is
available by referring the list of references in: Table A-2 References 2 - Operating
Manuals PDM (Page 281).

Safety instructions
WARNING
Laws and directives
The failure to observe directives and laws when connecting and installing increases the
danger of explosion and leakage due to improper handling. When connecting and installing,
observe the test certificates, stipulations and laws applicable in your country in order to
avoid danger.
These include, for example:
•IEC 60079-14 (international)
•National Electrical Code (NEC - NFPA 70) (USA)
•Canadian Electrical Code (CEC) (Canada)
•EN 60079-14 (formerly VDE 0165, T1) (EU)
•EN 61010
•Ordinance on Industrial Safety and Health (Germany)
WARNING
Device modifications
Danger to personnel, system and the environment can result from modifications and repairs
to the device, especially in hazardous areas.
•Only carry out modifications or repairs that are described in the instructions for the
device. Failure to observe this requirement cancels the manufacturer's warranty and the
product approvals.

2.3.1
Prerequisites for safe use
In terms of safety, this device left the factory in perfect condition. In order to maintain this
status and to ensure safe operation of the device, observe these instructions and all the
information relevant to safety.
2.3.2
Security messages
Siemens provides automation and drive products with industrial security functions that
support the secure operation of plants or machines. They are an important component in a
holistic industrial security concept. With this in mind, our products undergo continuous
development. We therefore recommend that you keep yourself informed with respect to our
product updates. Detailed technical information can be found at:
http://support.automation.siemens.com (https://support.industry.siemens.com).
To ensure the secure operation of a plant or machine it is also necessary to take suitable
preventive action (e.g. cell protection concept) and to integrate the automation and drive
components into a state-of-the-art holistic industrial security concept for the entire plant or
machine. Products used from other manufacturers should also be taken into account here.
You will find further information under:
http://www.siemens.com/industrialsecurity (http://www.siemens.com/industrialsecurity).

Communications
Note
Communication protocols
The devices described in this documentation are
able to communicate using Ethernet and
MODBUS
TCP. The protocols used are basically non-secure in the sense of IT security.
•
Make sure that only secure connections are used for communication.
•
Only use the device within appropriately secure networks.
Note
Illegal Ethernet connection
Illegal Ethernet connections to the analyzer device can bypass firewalls.
Make sure that the analyzer device is not connected to or can be connected to two separate
Ethernet networks.
2.3.4
Qualified personnel
Qualified personnel are individuals who are familiar with the installation, mounting,
commissioning, and operation of the product. These individuals have the following
qualifications:
●They are authorized, trained or instructed in operating and maintaining devices and
systems according to the safety regulations for electrical circuits, high pressures, and
aggressive as well as dangerous media.
●For explosion-proof devices: They are authorized, trained, or instructed in working on
electrical circuits for systems in hazardous areas.
●They are trained or instructed in maintenance and use of appropriate safety equipment
according to the safety regulations.
2.3.5
Automatic reset
All SIPROCESS GA700 devices feature internal monitoring. When this monitoring is
activated, the standard digital outputs switch after about 4 seconds for a period of approx. 60
seconds to "inactive", i.e. to a recognized safe operating mode. These times are valid for
devices manufactured as of 09/2017. You can find this information on the nameplate. It can
take up to 10 seconds for older devices to switch over, and up to 100 seconds to switch to
safe operating mode.

General information
2.3 Information on use
Operating with the Local User Interface
18 Operating Manual, 06/2017, A5E31930478-05
If you are using SIPROCESS GA700 devices in critical processes, observe the following
information:
●Monitor the limits externally via the control system.
●Read out the device status only via the digital outputs of the analyzer module.
●Use an available manual measuring range switchover instead of the autoranging.
●Only use the "Total" parameter with the "Off" setting for the measuring range switchover.
●If you use the "Correction of cross-interference" and "External pressure compensation"
functions, store suitable substitute values.
●Only access the measured value via an analog output.

Overview
Distinction
The devices of the SIPROCESS GA700 product range are of modular design, and consist of
the basic device and at least one analyzer module. Certain analyzer and option modules can
be retrofitted.
Table 3- 1 Device/enclosure variants
Basic device (rack-mounted or wall enclosure)
Rack-mounted or wall-mounted device
Metal enclosure for wall mounting/for installation
in 19" rack, in each case with:
•Local user interface
•Processing module (PM)
•Power supply unit
•Preparation to accommodate analyzer and/or
option modules
General rule: Basic device (rack-mounted or wall
enclosure) with at least one analyzer module
Measuring principles/measuring tasks
The analyzer modules are matched with specific sample gas components and measuring
ranges. Various types of measuring methods are implemented:

Note
Condensation in the analyzer module
Use a sample gas cooler that reduces the dew point of the sample gas to the extent that the
gas in the analyzer does not condense. The internal sample gas paths are not heated. The
sample chamber is warmed to 72 °C.
