concentration of liquid media.
The CUM 223/253 is particularly suitable for
use in the following areas of application:
•Chemical industry
•Pharmaceutical industry
•Drinking water treatment
•Condensate processing
•Municipal sewage treatment plants
•Water conditioning
2.2 General safety instructions
This device has been manufactured for safe
operation according to the state of the art in
engineering and conforms to the applicable
regulations and European standards (see
Technical data). It has been designed
according to EN 61010-1 and has left the
manufacturer’s works in perfect condition.
However, if used improperly or for purposes
other than the intended purpose, it may be
dangerous, e.g. due to incorrect connection.
Warning:
•Operating this instrument in any
way other than as described in
these instructions may compro-
mise the safety and function of the
measuring system and is therefore
impermissible.
•The notes and warnings in these
installation and operating
instructions must be strictly
adhered to!
2.3 Installation, start-up, operation
Warning:
•This device may only be installed,
connected electrically,
commissioned, operated and
serviced by properly trained
personnel authorized by the
system operator.
•The personnel must be familiar
with these operating instructions
and must adhere to the
instructions described therein.
•Make sure that the power supply
ratings match the data specified
on the nameplate before you
connect the instrument to a power
source.
•A clearly identified mains
disconnecting device must be
installed close to the instrument.
•Live components can be touched
through the vent slots in the
housing and the openings on the
rear of the housing. Do not insert
tools, wires, etc., in these slots
(CUM 223 only).
•Check that all connections have
been properly made before
powering up the system!
•Damaged equipment that may be
dangerous must not be operated
and should be clearly identified as
being defective.
•Any troubleshooting of the
measuring system is to be
performed exclusively by
authorized, trained personnel.
•If faults cannot be remedied, the
instrument must be removed from
service and secured to prevent
accidental start-up.
•Repairs not described in these
operating instructions may only be
performed at the manufacturer’s
works or by the Endress+Hauser
Service Organization.

3.5 Sensor installation and measuring cable connection
Measuring cable connection
The sensor is connected via a special
screened, multi-core cable which is
completely terminated and permanently
connected to the sensor.
Use junction box, e.g. VBM (see chpt. 9) to
extend the measuring cable.
Termination instructions are supplied with the
measuring cables.
Note:
•Connectors, cable ends and termi-
nals are to be protected against
moisture to prevent inaccurate
measurement!
•The instrument is approved for
protection class II and is generally
connected without protective earth.

4.3 Key functions
CAL key
When the CAL key is pressed, the instrument
prompts for the calibration access code (fixed
setting: 22 for calibration or any other number
to view the calibration data). Acknowledge
with the CAL key to proceed. Use the CAL
key to continue through the calibration
process.
Hinweis:
The calibration data set in function
group C are used for calibration.
ENTER key
The ENTER key has several functions:
- It calls up the setup menus from the
measuring mode
- It is used to store (acknowledge) data
entered in setup mode
- It is used to start calibration (same
function as CAL key)
PLUS key
MINUS key
The PLUS and MINUS keys have the following
functions:
- They are used to select function groups;
to set parameters and numeric values
(the setting speed increases when the
key is held down); and
- to operate the relays in manual mode
(see chapter 4.2).
- In the measuring mode, the PLUS key
switches to °F and disables the
temperature display (see chapter 4.7),
- while
the MINUS key selects the error display
(see chapter 4.7)
REL key
The REL key is used in manual mode to
switch between the relays and the manual
start cleaning function.
AUTO key
This key is used to toggle between the
automatic and manual modes of operation.
Escape function
Press the PLUS and MINUS keys
simultaneously to return to the main menu,
in calibration mode: at the end of calibration.
Press the PLUS and MINUS keys again to
return to the measuring mode.
Locking the hardware
Access to field operation can be locked for
communication via HART or PROFIBUS.
Press the PLUS key and the ENTER key at the
same time to lock the instrument. The code
prompt displays the code 9999.
Unlocking the hardware
To unlock, press the CAL and MINUS keys at
the same time. The code prompt displays the
code 0.

4.4 Auto / manual mode of operation
Auto mode
In this mode of operation, the relays
are controlled by the transmitter.
REL key
The REL key is used to select one of
the relays present in the instrument.
Switching to manual mode
The instrument is switched to the
manual mode pressing the following
keys:
Press AUTO key.
Enter code 22.
Select relay or function. Press the
REL key to toggle between the
relays. The display shows the
selected relay in the second line.
Set the relays. Switch on with PLUS,
switch off with MINUS. The relay
state remains in effect until it is
actively reset.
Press AUTO key for returning to the
measuring mode.
Note:
•Enable the manual mode by
entering access code “22”.
•The operating mode remains in
effect even after a power failure.
•The manual mode takes
precedence over any other
automatic function (hold).
•Hardware locking in the manual
mode is not possible.
•The manual settings remain in
effect until they are actively reset.
•Error code 22 is signalled in the
manual mode.
