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!

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.

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.

SmartMedia card: Application

Use as memory card in combination with additional functions.
Additional functions must be ordered separately (release via TAN).

Types of SmartMedia cards

The SmartMedia cards are delivered from the manufacturer as

• Softwar

e update (SW 700-106, see Pg 52)

• Memory card (additional function SW 700-1xx, see Pg 56)

Using commercially available SmartMedia cards

Commercially available SmartMedia cards can be used as memor
(Softwar

e updates are supplied by the manufacturer and are device-specific).

y card

The following types of cards are supported: 8 MB, 16 MB, 32 MB, 64 MB
and 128 MB storage capacity. Externally produced files, such as from a
digital camera, are tolerated. Long file names can be read. The M 700
generates file names in the 8.3 format (8 characters file name, 3 characters
program-specific file name extension).

Formatting a commercial SmartMedia card

Some devices (e.g. digital cameras, scanners) cause a formatting of the
SmartMedia card which does not correspond to the SSFDC specification or
the SmartMedia Interface Library (SMIL). The manufacturer therefore recom­mends to format a commercial SmartMedia card as M 700 memory card
prior to first use.

Additional function SW 700-106: Software update

For a software update (additional function SW 700-106), the manufacturer
supplies a specially formatted SmartMedia card. The M 700 replaces its own
firmware (operating program) by the new version (“Update”).

Caution!

During a software update the analyzer is not operable!
After a software update you should check the configuration.

This icon indicates that a SmartMedia card is inserted in the slot.

Time constant.

Time constant of output filter

To smoothen the current output, a low-pass filter with adjustable time
constant can be switched on. When there is a jump at the input (100 %),
the output level is at 63 % after the time constant has been reached.
The time constant can be set from 0 to 120 sec. If the time constant is set
to 0 s, the current output follows the input.

Note:

The filter only acts on the current output and the current value of the
secondary display, not on the measurement display, the limit values, or the
controller!

Relay contacts: Protective wiring

Protective wiring of relay contacts

Relay contacts are subjected to electrical erosion. Especially with inductive
and capacitive loads, the service life of the contacts will be reduced.
For suppression of sparks and arcing, components such as RC combinations,
nonlinear resistors, series resistors and diodes should be used.

Warning!
Make sure that the maximum ratings of the relay contacts are
not exceeded even during switching!

Information concerning relay contacts

As delivered, the relay contacts are suitable for low signal currents (down to
approx. 1mA). If currents above approx. 100 mA are switched, the gold
plating is destroyed during the switching process. After that, the contacts
will not reliably switch low currents.

Calculation of new variables from measured variables

Calculation Blocks

Two measuring modules with all their measured values serve as input for the cal­culation block. In addition, the general device status (NAMUR signals) is taken into
account. The following variables are calculated from the existing values:

• Ratio

• Pass (passage)

• Reject (rejection)

• Measured-value difference

• Deviation

• pH value calculation by means of dual conductivity measurement
These output variables are then available in the system and can be assigned
to the outputs (current, limit values, display ...)

process variables to be displayed can be selected using the softkeys under­neath.

Sensor coding

Here, internal settings for electrodeless sensors are encoded
(Cond Ind module).

Slope

The slope of an electrode is the voltage change per pH unit.
For an ideal pH electrode, it lies at -59.2 mV/pH (25 °C).

Viewing level

Menu level of the Parameter Setting menu. Display of all device settings,
however no editing possible.

Zero point

The zero point is the voltage value delivered by an electrode at 25 °C and
pH = 7.00. For an ideal pH electrode, it lies at 0 mV.
In practice, the real zero point is slightly different.
