Intended use
The 8285 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 8285 is a flexible measuring system for continuous measurements in the
field of liquid analysis. Thanks to its modular design, it can be easily 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 sturdy enclosure (IP 65) can be wall or pipe mounted or fixed
into a control panel. The version with hygienic, polished stainless steel enclo-
sure allows application in the field of biotechnology, food processing, and in
the pharmaceutical industry. The Protos version with coated steel enclosure
– extremely corrosion resistant – has been developed for application in the
chemical industry, environmental engineering, water and waste-water treat-
ment, 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
During operation, the basic unit 8285
may be opened briefly to replace the
SmartMedia card. The mains terminal
cover must be opened only when the
unit is de-energized.
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!
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.

Information on commissioning/start-up
Installation:
The power supply must be disconnectable near the device by a two-poled
switch incorporated in the building installation. This switch must meet the
requirements of EN 60947-1 and EN 60947-3, be marked as disconnect
device for teh Model 8285, and be easily accessible by the user.

10 8285
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 Series 8285 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 adjust-
able 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 docu-
mented in the Audit Trail Log on the SmartMedia card. The recording can be
encoded.
Conformity with FDA 21 CFR Part 11

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 assign-
ments remain visible even if further
modules are inserted.
Slot for SmartMedia card
Data recording
The SmartMedia card expands the
measurement recorder capacity to
> 50000 records.
Exchange of parameter sets
5 parameter sets can be stored on
the SmartMedia card, 2 of them
can be loaded to the analyzer and
switched by remote control.
Parameter sets can be transmitted
from one analyzer to the other.
Function expansions are possible
with additional software modules,
which are released using transaction
numbers (TAN).
