How to order an additional function
Device-specific TAN (transaction number)
Additional functions expand the device capabilities.
The additional functions are device-specific. When ordering an additional
function, you therefore have to specify the serial number and hardware
version of your FRONT module in addition to the respective order number.
The manufacturer then supplies a TAN (transaction number) to release the
additional function.

Intended use
The M 700(X) modular process analysis system is preferably used to measure
and process electrochemical quantities in liquids. It has a modular design and
consists of the BASE power supply unit, the FRONT door and different measuring and communication modules.
The M 700X is intended for operation in locations subject to explosion hazards which require equipment of Group II, device category 2(1), gas/dust.
The M 700(X) is a flexible measuring system for continuous measurements in
the field of liquid analysis. Thanks to its modular design, the M 700(X) can
easily be adapted to your measuring task. Flexible use of plug-in modules
allows combined measurements as well as later expansions or modifications.
The measured variables depend on the measuring modules installed.
Communication modules are available for further processing of the output
signals. The rugged enclosure (IP 65) can be wall or pipe mounted or fixed
into a control panel. The M 700 version with hygienic, polished stainless steel
enclosure allows application in the field of biotechnology, food processing,
and in the pharmaceutical industry. The M 700 version with coated steel
enclosure – extremely corrosion resistant – has been developed for application in the chemical industry, environmental engineering, water and wastewater treatment, and for application in power plants .
Caution!
Never expose the display to direct sun light! Only operate the display within
the temperature range of 0 °C up to 50 °C max.

Safety information
Application in hazardous locations
M 700X modular process analysis system
The M 700X modular process analysis system is intended for operation in
specific environments and specific fields of application. These are listed in the
instruction manual as specifications for environment, installation and commissioning, intended use (= application), assembly and dismantling, and
maintenance.
Observe the influences of humidity, ambient temperature, chemicals and corrosion. If the specifications in the instruction manual are not sufficient for
assessing the safety of operation, e.g. because your specific applications are
not described, please contact the manufacturer to make sure that the application is possible and safe.
Prerequisite to safe use of the equipment is the observance of the specified
ambient conditions and temperature ranges.
When using the M 700X modular process analysis system, the stipulations
for electrical installations in hazardous areas (EN 60079-14) must be
observed. When installing the device outside the range of applicability of the
94/9/EC directive, the appropriate standards and regulations in the country
of use must be observed.
The module has been developed and manufactured in compliance with the
applicable European guidelines and standards. Compliance with the
European Harmonized Standards for use in hazardous locations is confirmed
by the EC-Type-Examination Certificate. Compliance with the European
guidelines and standards is confirmed by the EC Declaration of Conformity.
The EC Declaration of Conformity and the EC-Type-Examination Certificate
are included in the instruction manual.
There is no particular direct hazard caused by the operation of the device in
the specified environment.
13
Safety information
During operation, the M 700(X)
modular process analysis system
may be opened briefly to replace
the SmartMedia card. The mains terminal cover must be opened only
when the unit is de-energized.
Installation:
The power supply must be disconnectable using a 2-pole disconnect
switch installed near the M700(X).
This switch must meet the requirements of EN 60947-1 and EN 60947-3,
be marked as disconnecting device for M 700(X) and be easily accessible by
the user.
Information on commissioning/start-up
Caution!
• Before commissioning it must be proved that the device may be
connected with other equipment.
• Commissioning must only be performed by authorized and trained personnel!
• The combination of hazardous-area and safe-area modules
(mixed configuration) is not permitted.
Whenever it is likely that protection has been impaired, the device shall be
made inoperative and secured against unintended operation. The protection is
likely to be impaired if, for example:
• the device shows visible damage
• the device fails to perform the intended measurements
• after prolonged storage at temperatures above 70 °C
• after severe transport stresses
Before recommissioning the device, a professional routine test in accordance
with EN 61010-1 must be performed. This test should be carried out by the
manufacturer.

M 700(X)
Conformity with FDA 21 CFR Part 11
In their directive “Title 21 Code of Federal Regulations, 21 CFR Part 11,
Electronic Records; Electronic Signatures” the US American health agency
FDA (Food and Drug Administration) regulates the production and processing
of electronic documents for pharmaceutical development and production.
This results in requirements for measuring devices used for corresponding
applications. The following features ensure that the M 700(X) modular
process analysis system meets the demands of FDA 21 CFR Part 11:
Electronic Signature
Access to the device functions is regulated and limited by individually
adjustable codes – “Passcodes”. This prevents unauthorized modification of
device settings or manipulation of the measurement results. Appropriate use
of these passcodes makes them suitable as electronic signature.
Audit Trail Log
Every change of device settings can be automatically recorded and documented in the Audit Trail Log on the SmartMedia card. The recording can be
encoded.

• Exchange of parameter sets
5 parameter sets can be stored
on the SmartMedia card, 2 of them
can be loaded to the M 700
and switched by remote control.
Configurations can be transferred
from one M 700 to the other.
• Function expansions
are possible with additional software
modules which are released using
transaction numbers (TAN).
• Software updates
Terminal plates
of “hidden” modules
Each module comes with an adhesive
label containing the contact assignments.
This label should be sticked to the inner
side of the front (as shown).
Then, the terminal assignments remain
visible even if further modules are
inserted.
Replacing the front module
Pull off power cord and ground wire.
To separate the M 700 FRONT from
the M 700 BASE, turn the retaining screws
of the pivot hinge by 90°.
The circumferential sealing
guarantees IP 65 protection and allows spray
cleaning / disinfection.
