2 Safety instructions
2.1 Intended application
Liquisys M CUM 223 / 253 is a field-tested
and reliable transmitter to determine the
turbidity and the solids concentration of fluid
media.
The Liquisys M CUM 223 / 253 is particularly
suitable for use in the following areas:
•Chemicals
•Pharmaceuticals
•Drinking water treatment
•Condensate treatment
•Municipal sewage treatment plants
•Water conditioning
2.2 General safety notes
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

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
compromise 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

•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 powre
source.
•A clearly identified mains
disconnecting device must be
installed closed 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
any 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.

3.5 Sensor installation and measuring cable connection
Measuring cable connection
The terminal block is located in a separate
connection compartment which is accessible
by opening the plastic cover. Remove the
pre-pressed knock-outs for cable entry.
The sensor is connected via a multiple-core,
special screened cable which is completely
terminated and permanently connected. Use
a junction box, e.g. VBM to extend the
measuring cable. Termination instructions are
supplied with the measuring cables.
Note:
•Protect cable ends and terminals
against moisture to prevent
inaccurate measurement!
•For further information on cables
and junction boxes refer to chap.

4.3 Function of the operating keys
CAL key
When the CAL key is pressed, the instrument prompts for the calibration
access code (fixed setting: 22 for calibration; any setting for calibration
data checking). Acknowledge with the CAL key to proceed. Calibration
uses the calibration data set in Function Group C.
ENTER key
The ENTER key has the following functions:
Opens the Setup menu in Measurement mode
Stores (acknowledges) entered data in Setup mode.
Moving on within the function groups.
PLUS key and MINUS key
The PLUS and MINUS keys have the following functions:
Selection of function groups
Setting of parameters and numeric values
Relay operation in manual mode (see chap. 4.4).
Pressing the PLUS key allows you to switch between the current
output in % and mA.
Repeatedly pressing the PLUS key displays the following settings in
sequence as secondary measured values:
1. Temperature display in °F
2. Hiding the temperature display
3. Measured value display in FNU
4. Back to basic setting
Repeatedly pressing the MINUS key displays the errors:
1. The current errors are displayed one after the other (max. 10)
2. After all the errors are displayed, the standard display is unhidden.
In function group F, you can define an alarm for each error code
separately.
REL key
The REL key is used in manual mode to switch between the relays and
the manual start cleaning function.
AUTO key
The AUTO 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. Press the PLUS and MINUS keys again to return to measuring
mode.
Locking the keypad
