2. General safety instructions
2.1 Intended use
Thesensor measuring modulesand retrofit kitsare designed tobe
installed in the MFC control unit.
The operational safety of the sensor measuring modules and
retrofit kits can onlybe guaranteed solong as they are used strictly
as intended. They may only be used for the purpose defined in the
order and under the operating conditions indicated in the
technical specifications. Modifications to the sensor measuring
module and retrofitkits which go beyond those described in this
manual are not permitted.
Compliance with the intended use also includes reading this
instruction manual and observing all the instructions it contains.
The operator bears full and sole responsibility if this unit is put to
any use which does not comply strictly and exclusively with this
intended use.

2.2 General safety instructions
Evoqua Water Technologies GmbH places great emphasis on
safety when work is performed using the sensor measuring
modules and retrofit kits. Safety is our guiding principle right from
the design phase; the system is therefore equipped with safety
features.
Safety instructions The safety instructions in this documentation must be observed
unconditionally at all times. Additional industry-wide or in-house
safety regulations also continue to apply.
State-of-the-art technology The sensor measuring modules and retrofit kits were constructed
in accordance with the state of the art and all recognized technical
regulations relevant to safety. However, if the unit is used by
untrained personnel, potentially fatal hazards may occur for the
user or third parties during use of the unit, and damage to the
sensor measuring modules, retrofit kits and other equipment may
also result.
Worknotspecifically describedin this instructionmanualmayonly
be performed by authorized personnel.
Personnel The operator running the systemmust ensure that only authorized
and qualified specialists work with and on the system and only
within their assigned areas of responsibility. "Authorized
specialists" refers to trained technicians of the operator, Evoqua
Water Technologies GmbH and, if applicable, the service partner.
Only qualified electricians may perform work on electrical
components.
Spare parts / components Correct operation of the sensor measuring modules and retrofit
kits is only guaranteed if original spare parts and components are
used in the combinationdescribed in this Operating Manual. If this
stipulation is not observed, there is the risk of malfunction or
damage to the sensor measuring modules and retrofit kits
Extensions and conversions The system must not, without the express, prior, written consent of
the manufacturer, be modified, extended, or converted in any way
that might adversely affect its safety.
Electrical power During normal operation, the MFC must remain closed.
Switch off the complete system and secure against reactivation
prior to installation, inspection, maintenance and repair work.
Connect cables in accordance with the terminal diagrams.
Please note
For more information, including the general safety instructions,
please review the instruction manual „MFC”.

In principle, the following sensor measuring module types or
retrofit kits can be installed in module slots 1 to 4:
DES - for DEPOLOX®5 flow block assembly
DES - for DEPOLOX®4 flow block assembly with
PT100 temperature option
DES - for membrane sensors: free chlorine FCI,
chlorine dioxide (CD7), ozone (OZ7), total chlorine
TC1
pH - pH value
mV - Redox value
F-- Fluoride value
mS - Conductivity
mA/V - Input module
Depending on the selected application, the menus are initialized
according to the installed sensor modules when the device is
switched on. See Instruction Manual „MFC” Chapter 4.4
"Applications".
Sensor measuring module 1
(MOD 1) Sensor measuring module 1 is regarded as the main measurement and therefore has the most controller functions
(ratiocontrol, single feedback close-loop control or combi-control).
No controller output is available for application 1.
Sensor measuring module 2
(MOD 2) Depending on the application, sensor measuring module 2 has eitherasinglefeedbackclose-loopcontrol(application3),twotime
switch contacts (application 4) or it is used to optimize the
controller setpoint in sensor module 1 (application 5).
Module slot 5
(MOD 5) Module slot 5canonlybe equipped with amA/Vsensormeasuring module, which is used to record further process parameters such
as flow rate or external setpoint/dosing factor.

Module slot 6
(MOD 6) As an option, module slot 6 can be equipped with a four-way mA output card. Each mA output can be optionally assigned with a
measured value or also with a controller control signal
(Ym feedback / Yout).
Module slot 7
(MOD 7) Module slot 7 is equipped with an eight-way relay card. Depending on the application, controller output and selected alarm
assignment, the relays are assigned different functions.
Please note
Afterthemoduleshavebeen installed, the applicationsettingmust
be reviewed and edited if necessary (see Instruction Manual
„MFC„ Chapter 4.4 "Application".
Furthermore, the controller settings, measuring ranges and other
operating parameters must be reviewed and edited if necessary
(see Instruction Manual „MFC”).
The sensors must calibrated after installation.
