2 Safety
2.1 Intended use
The measuring transmitter Mycom CPM 152
is a microprocessor-based measuring and
control instrument used to determine and
evaluate the pH value and the redox potential.
Since it has been designed to permit
extensive programming and the addition of
optional plug-in modules, it can be adapted to
carry out complicated control assignments
and to be incorporated in automatic process
control systems.
If the version of the Mycom CPM 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 not therefore allowed.
Installation, start-up, operation
The Mycom CPM 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 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 therein.
2.3 Safety functions
•Access codes:
Unauthorised access to the calibration and
configuration data of the measuring
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 fail-safe by design,
i.e. the alarm is also actuated immediately
in case of power failure.
•Data integrity:
The set configuration is maintained
even after a power failure.
•Immunity to interference:
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.

4.4 Electrical connection of Mycom CPM 152
Warning:
•Only appropriately trained
personnel is allowed to work on
the instrument when the system
is live and is connected to the
mains.
•A mains disconnection device
must be installed near the
instrument and must be identifed
as the mains disconnecting
device for the CPM 152
(see EN 61010-1).
•Do not start up the instrument
until a protective wire has been
connected!
•Before connecting the instrument
to the mains, make sure the
mains voltage matches the
voltage rating on the nameplate!
•When an instrument with
explosion protection is being
connected, it is vital that the
appropriate regulations are
observed (see chapter 4.4.2).
Caution:
•All lines conducting signals are
to be shielded according to
VDE 0165 and run separately
from other control lines.
Note:
•Immunity against interference can
only be guaranteed if the
transmitter is earthed and the
screen ground line is kept as
short as possible (do not solder
an extension onto the screen)!
•The earthing happend with the
earth terminal or the inner
PE-terminal block
•If the instrument is being installed
on a post, grounding the post is
also recommended.
Instrument connections
•Undo the four screws in the bottom third of
the front of the housing.
•Remove the cover of the connection
compartment.
•A connection diagram and information
about the specific module connections can
be found folded up in the cover.
•Replace the plugs by additional cable
glands if required.
•Feed the cable through the cable glands
into the connection compartment.
Use metal cable gland for pH- / Redox
signal line.
•Connect the cables in accordance with the
connection diagrams on the following
pages.
•Tighten the cable glands securely to make
sure the connections are provided with the
necessary strain relief.
Warning:
In the non-Ex area, the output
contacts can also be connected to
the instrument’s power supply.
To do this, the thin section provided
in the separating wall on the
connection compartment lid must be
broken out with a pair of pliers.
Now a cable connection between
the right and left parts of the
connection compartment can be
established by attaching the cable
carefully and without forming a loop
in the cable clip provided.
For this purpose the supply
connection has a second terminal
»L«resp. »L+«.

4.4.2 Connection of Mycom CPM 152-Z in Ex areas
General instructions about installation in potentially explosive surroundings
Instruments with the letter Z (standing for
“certificate”) in their name have been
manufactured and tested in accordance
with the standardised European regulations
(CENELEC) for “Electrical equipment for
potentially explosive surroundings”. A copy
of the conformity certificates issued by the
Bergbau-Versuchsstrecke (BVS) is enclosed
with this instruction manual.
There are detailed standards covering both
production and operation, in Germany
including:
•“Decree about electrical equipment in
potentially explosive surroundings”(Elex V)
Make sure you comply with DIN VDE 0165
in the installation of your instrument!
Make sure you comply with Elex V §9 when
your are repairing or modifying
electrical equipment!
•“Decree about flammable liquids”(VbF)
•“Equipment Safety Act”(GSG)
•“Explosion guidelines issued by the work
safety association of the chemicals
industry”(EX-RL)
•“Accident prevention regulations: electrical
equipment”
The measuring transmitter Mycom CPM 152-Z
is manufactured in accordance with the
explosion protection regulations and is
allowed to be installed in Zone 1 and 2.
Electrodes (measuring chains) that are
suitable for the instrument can also be
operated in Zone 1 without a separate
approval, because their electrical data
mean that they are safe in themselves. Other
equipment may only be connected to the
Mycom measuring transmitter (with explosion
protection) - Z models - if this equipment has
an electrical input circuit that is intrinsically
safe.
Warning:
Display cover has to be closed
during operation under ex conditions.
Note:
Useful information about the
installation and operation of
electrical equipment in potentially
explosive surroundings can be
found in the Endress+Hauser
brochure GI 003/11/en “Explosion
protection of electrical equipment
and systems”. This brochure can be
ordered from the Endress+Hauser
sales offices.

4.5 Connection of pH and redox electrodes
4.5.1 Special measuring cables
The pH and redox electrodes are connected
via special ready-made multi-wire and
shielded measuring cables:
•CPK 1 for electrodes without Pt 100
•CPK 7 for electrodes with Pt 100
•CPK 9 for electrodes withESA/ESS plug-in
head (TOP 68)
•CPK 6 for:
–Sensopac with double reference electrode
–1 pH single electrode, 1 reference
electrode and 1 Pt 100
–2 pH combination electrodes and 1 Pt 100
or 1 common reference electrode, resp.
If you need to extend the measuring cables,
use the junction box VBA and
non-ready-made cables:
•CYK 71 for CPK 1, CPK 7 and CPK 9
•DMK for CPK 6
(see connection accessories).
Caution:
It is vital to protect plugs and
terminals against moisture, because
moisture leads to inaccurate
measuring results!
For stranded inner wires use wire
end sleeves.

4.5.2 Symmetrical or asymmetrical connection of electrodes?
Caution:
The instrument has been configured
for symmetrical measurement
(with potential matching, PM).
If asymmetrical measurement is
required, the configuration has to
be changed accordingly
(see chapter 7.1.1).
Symmetrical high-impedance (with PM):
Caution:
If a symmetrical, high-impedance
connection is required, the cable for
the potential matching pin has to be
connected to the terminal PA of the
instrument.
The potential matching pin must
always be in contact with the
medium, i.e. it must also be
immersed in the buffer solution
during calibration.
Advantage of symmetrical connection:
The reference system of the pH measuring
chain is connected to a high-impedance
measuring input just like the pH electrode.
This eliminates any current leakage.
Measurement is also made less of a problem
in difficult ambient conditions (e.g. high flow
rates, high-impedance media or partially
soiled diaphragm).
Asymmetrical high-impedance
(without PM):
If the instrument has an asymmetrical, high-
impedance input, pH measuring chains can
be connected in conjunction with holders
without an additional potential matching pin.
If a potential matching pin is already
available, connect it to terminal PE.
Disadvantage of asymmetrical connection:
The reference system of the measuring chain
is more affected by leakage, possibly leading
to measuring errors when operating close to
maximum limits (see symmetrical, high-
impedance instrument input).
It is not possible to monitor the reference
electrode by the SC system
(see chapter 7.4) in the case of
asymmetrical measurement.
