2 Safety
2.1 Intended application
The Mycom CLM 152 measuring transmitter is
a microprocessor-controlled measuring and
control instrument used to determine and
evaluate specific conductivity. Since it has
been designed to permit extensive
programming
and the addition of optional plug-in modules,
it can be adapted to different process
applications. If the version of the Mycom
CLM 152 with explosion protection is chosen,
it can be operated in explosive atmospheres
as well.
2.2 General safety instructions
Warning:
Operating this instrument in any way
other than described in these
instructions may compromise the
safety and function of the measuring
system and is therefore not allowed.
Installation, start-up, operation
The Mycom CLM 152 instrument has been
designed and manufactured for safe
operation according to the latest state of the
art and conforms to the prevailing regulations
and EC directives, see “Technical data”.
However, if used improperly or other than for
the intended purpose, it may be hazardous,
e.g. due to improper connection.
Installation, electrical connection, start-up,
operation and maintenance of the measuring
system must therefore be performed
exclusively by trained specialist personnel
properly authorised by the system operator
for such work. The specialist personnel must
be familiar with these operating instructions
and must adhere to the instructions
contained in this document.
2.3 Safety functions
Access authorisation:
Unauthorised access to the calibration and
configuration data of the transmitter is
effectively prevented by access codes.
Alarm functions:
The fault contact is activated in case of
system faults, temperature sensor failure and
serious defects.
The alarm contact is designed as a fail-safe
circuit, i.e. the alarm is activated
immediately in case of power failure.
Data integrity:
The set configuration is maintained even in
the event of a power failure.
Electromagnetic compatibility:
The instrument is protected against
interference, such as pulse-shaped
transients, high frequency and electrostatic
discharges in accordance with the prevailing
European standards.
This is, however, only the case for instruments
connected as described in these installation
and operating instructions.

3 Instrument description
3.1 Applications
The Mycom CLM 152 measuring transmitter is
specially designed for carrying out measuring
and control tasks in the following applications:
•Foodstuffs industry
•Pharmaceuticals
•Chemical process engineering
•Water treatment
•Drinking water
•Monitoring ultra-pure water
3.2 Operating principle
Inductance principle
In inductive conductivity measurement, a
transmitter coil generates a continuous
alternating magnetic field that induces an
electric voltage in a liquid.
A current flows due to the ions present in the
liquid. The current increases as the ion
concentration rises. The ion concentration
acts as a measure of conductivity. The
current in the liquid generates an alternating
magnetic field in the receiving coil.
The resulting current induced in the receiving
coil is processed in the measuring instrument
and is output as a conductivity value.
The advantage of this set-up is the fault-free
measurement in liquids that have a tendency
to sediment; there is no electrically
conductive connection between the sensor
and the liquid and there is no polarisation
since there are no electrodes.
Conductance principle
When ions are subjected to an electrical field,
and depending on their electrolytic excess
carrier, they either become cations and
migrate to a positively charged electrode, or
they become anions and migrate to a
negatively charged electrode. The migration
speed of the ions is directly proportional to
the current strength recorded in the
measuring instrument as a conductivity value.
Polarisation compensation (conductive)
Polarisation effects in the boundary layer
between the electrode and the measuring
solution limit the measuring range of
conductive sensors. The Mycom
CLM 152 measuring transmitter can detect
and compensate for polarisation effects using
an innovative, intelligent signal evaluation
process. This results in a significant
expansion of the useful measuring range of a
sensor (cf. Overview of Conductivity Sensors).
3.3 Measuring functions
Concentration measurement
In this operating mode, the instrument stores
the data for NaOH, HNO3,H
2SO4and H3PO4.
The operator can enter and store the
individual data for four other substances
within the permitted ranges, and, if required,
can activate them as a concentration
measuring range. See Chapter 7.1.1
“Measured variable”.
Differential measurement
(if equipped with two measuring channels)
Two sensors are used at different points in a
process, e.g. to monitor heat exchangers
(upstream and downstream of the exchanger)
in media separation or mixture control
applications. The difference between the two
measuring results is used to control the
process.
Measuring range switch-over
The instrument can store the following
settings for four measuring ranges:
•Measuring range allocation for current
output (0/4 and 20 mA)
•Setpoint and hysteresis for existing
limit contacts.
•Temperature coefficients
•Type of temperature compensation
Switch-over takes place by internal
configuring the internal trigger thresholds or
alternative external by wiring the binary inputs
(add-on module FCXI required).

•Do not start the instrument without
a protective earth connection!
•Before plugging the instrument to
the mains, make sure that the
mains voltage is the same as the
voltage rating on the nameplate!
Warning:
All signal-carrying lines must be
screened in compliance with
VDE 0165 and routed separately
other control lines.
Note:
•Immunity to interference can only
be ensured if the screen earth is
kept as short as possible.
Do not solder an extension to the
screen!
•If the instrument is mounted on a
post, we recommend earthing the
post as well.
Instrument connections
•Remove the four screws in the bottom third
of the housing front panel.
•Remove the terminal compartment cover.
•You will find a wiring diagram and
information on the instrument-specific
module configuration folded up in the
cover.
•Replace the dummy plugs in the housing
base with the correct size and number of
Pg cable glands.
•Feed the cable through the Pg cable
glands into the terminal compartment .
•Connect the wires as specified in the
wiring diagrams depicted on the following
pages.
•Tighten the Pg cable glands to ensure the
proper strain relief.
Warning:
In the non-hazardous area, the
contact outputs can also be
connected to the instrument’s power
supply.
First break out the section in the
partition wall of the terminal
