2 Safety
2.1 Intended Application
The transmitter Mycom CLM 152 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 intrinsically safe design 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.
The Mycom CLM 152 instrument has been designed and manufactured for safe operation
according to the state of the art in engineering and conforms to the relevant regulations
and US and EC directives (see Technical Data). However, if used improperly or other
than 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
authorized by the system operator for such work. The specialist personnel must be
familiar with these operating instructions and must adhere to the instructions contained
therein.
2.3 Safety Functions
Access Code: Unauthorized access to the calibration and configuration
data of the transmitter is effectively prevented by access
codes.
Alarm Function: The failure contact is activated in case of system faults,
temperature sensor failure and serious defects.
The alarm contact is fail-safe by design, i.e., the alarm is
also actuated immediately in case of a power failure.
Data Integrity: The current configuration is maintained even after a power failure.
Electromagnetic compatibility: This instrument is protected against interference,
such as pulse-shaped transients, high frequency and
electrostatic discharges in accordance with the
current European standards.
This is, however, only the case for instruments
connected as outlined in these operating instructions.

8
2.4 Repairs, azardous Materials
The following procedures must be carried out before a Mycom CLM 152 is sent to
Endress+Hauser for repair:
 In every case, a note must be enclosed with the instrument, containing a description of
the fault, the application and the chemical and physical properties of the product being
measured.
 Remove all residue which may be present. Pay special attention to the gasket grooves
and crevices where fluid may be present. This is especially important if the fluid is
dangerous to health, e.g. corrosive, poisonous, carcinogenic, radioactive, etc.
 No instrument should be returned to us without all dangerous material being removed
first (e.g. in scratches or diffused through plastic).
Incomplete cleaning of the instrument may result in waste disposal or cause harm to
personnel (burns, etc.). Any costs arising from this will be charged to the owner of the
instrument.
See Return Authorization Policy on page 4.
2.5 Technical Improvements
The manufacturer reserves the right to modify technical data without prior notice.

3 Description
3.1 Application Areas
The Mycom CLM 152 transmitter is highly suitable for carrying out measuring and control
assignments in the following areas:
 Food industry
 Pharmaceutical industry
 Chemical rocess engineering
 Water treatment
 Drinking water
 Ultra ure water monitoring
3.2 Operating Principle
General Principle
The general rinci les of the instrument are the measurement of s ecific conductivity, the
measurement of s ecific resistance, concentration measurement, difference measurement
(if the instrument is equi ed with two measuring channels). The CLM 152 also rovides
remote measuring range switching.
Toroidal Conductivity
In toroidal conductivity measurement, an excitation coil generates a continuous magnetic
alternating field that induces an electric voltage in a liquid. The ions resent in the liquid
enable a current flow which increases with increasing ion concentrations. The ion
concentration serves as a measure of conductivity. The current in the liquid generates a
magnetic alternating field in the receiving coil. The resulting current induced in the
receiving coil is rocessed in the measuring instrument and out ut as a conductivity
value.
The advantages of this measuring rinci le are accurate measurement in media with a
tendency to sediment, no electrically conductive connection between measuring cell and
liquid, an no olarization since there are no electrodes.
3.3 Measuring Functions
Concentration Measurement
Data for NaOH, HNO3, H2SO4 and H3PO4 are ermanently stored in the instrument for this
mode of o eration. The user can enter the data of four other substances within the
ermissible value ranges, store them and activate them as concentration measuring
ranges whenever required. See cha ter 7 Measurement Ty e.
Difference Measurement
Two measuring cells are used at different oints of a rocess, e.g. for heat exchanger
monitoring (u stream and downstream from the exchanger) in media se aration or
mixture control. The difference between the two measured values is used to control the
rocess.
Polarization Compensation (Contacting)
Polarization effects in the boundary layer between the electrode and measuring solution
limit the measuring range of contacting measuring cells. The Mycom CLM 152 transmitter
can detect and com ensate for olarization effects using an innovative, intelligent signal
evaluation rocedure. This results in a significant ex ansion of the measuring cell
measuring range (overview of conductivity measuring cells).

10
Measuring Range Switc ing
The instrument can store the following settings for a total of four measuring ranges:
 Measured value assignment for current out ut (0/4 and 20 mA)
 Set oint and hysteresis values for the limit contacts
 Tem erature coefficients
 Alarm delay
 Ty e of tem erature com ensation
Switching is affected by configuring the internal trigger thresholds accordingly or by
controlling the binary in uts (requires ex ansion module FCXI).
3.4 Measuring System
A ty ical measuring system consists of:
 a toroidal conductivity measuring cell with an integrated tem erature sensor Pt 100
 an a ro riate conductivity measuring cable with or without junction box for cable
extension
 the Mycom CLM 152 transmitter

3.5 Major Features
 Illuminated gra hics dis lay, 128 x 64 dots
 Menu-guided lain text o eration
 Extensive and clearly structured rogramming alternatives
 Protection of configuration and calibration by user-defined access codes
 Modular design with lug-in modules, therefore, two measuring in uts, active current
in ut, two current out uts 0/4 to 20 mA and u to five contact out uts are ossible.
Note!
Ex ansion of the instrument by adding new lug-in modules or re lacement of
individual modules must, however, be carried out exclusively by the manufacturer
or the Endress+Hauser service organization (see the back cover of these o erating
instructions for a list of offices).

4.4 Electrical Connection of Mycom CLM 152
Warning!
 Only a ro riately trained ersonnel are allowed to work on the instrument when
the system is live and is connected to the ower su ly.
 A ower disconnect must be installed near the instrument.
 Do not start u the instrument until the PE conductor has been connected!
 Before connecting the instrument to the in ut ower source, make sure the voltage
matches the voltage rating on the name late!
Caution!
All lines conducting signals are to be shielded and run se arately from other
control lines.
Note!
 Immunity against interference can only be guaranteed if the shielded ground wire
is ke t as short as ossible. Do not solder an extension onto the shield!
 If the instrument is being installed on a ost, grounding the ost is recommended.
Instrument Connections
 Undo the four screws in the bottom third of the front of the front anel.
 Remove the connection com artment cover.
 A connection diagram and information about the lug-in modules installed can be
found folded u in the cover.
 Re lace the lugs in the holes on the bottom of the housing.
 Feed the cable through the conduit entries into the connection com artment.
 Connect the cables in accordance with the connection diagrams on the following
ages.
Warning!
In the non-Ex (non-hazardous) area, the out ut contacts can also be connected to
the instruments auxiliary ower su ly.
To do this, the thin section rovided in the se arating wall on the connection
com artment lid must be broken out with a air of liers.
Now a cable connection between the right and left arts of the connection
com artment can be established by attaching the cable carefully and without
forming a loo in the cable cli rovided.
