1.2 Designated use
The transmitter Mycom S CPM 153 is a measuring instrument for measurement pH
value or redox potential. The transmitter is designed for measuring or control tasks in
applications in the following industries:
•Chemical process systems
•Pharmaceuticals
•Foodstuffs
•Water conditioning and monitoring
•Wastewater treatment
•Sewage treatment plants
•Drinking water
The Ex version of the Mycom S CPM 153 allows operation even in hazardous areas
(refer to "Approvals" in the product structure on page 7).
The manufacturer is not liable for damage caused by improper use or use other than
that for which it is intended.
1.3 Installation, commissioning and operation
Note the following points:
•If the transmitter is used improperly or other than for its designated use, it may pose
a hazard, e.g. due to improper connection.
•Installation, electrical connection, start-up, operation and maintenance of
the measuring system must therefore be carried out exclusively by trained specialists
authorised by the system operator.
•Technical personnel must have read and understood these operating instructions and
must adhere to them.
•Always follow the regulations in your country pertaining to the opening
and repairing of electrical instruments.

1.4 Operational safety
#
Warning!
If the device is used for any application other than those described in these Operating
Instructions, it may lead to unsafe and improper functioning of the measuring system
and is therefore not permitted.
The instrument has been designed and tested according to the state of the art and left
the factory in perfect functioning order. The instrument meets all the prevailing
regulations and EC directives - see "Technical data".
However, always pay attention to the following points:
•Measuring systems used in Ex areas have a separate document (XA 236C/07/en)
which forms a component part of these Operating Instructions. Always follow the
installation regulations and the - partly deviating - connection data of the Ex documen-
tation as well. You can find the following symbols on the front page of the additional
Ex documentation (according to approval and test centre
(
0 Europe, 2 USA, 1 Canada).
•The measuring device complies with the general safety requirements in accordance
with EN 61010, the EMC requirements of EN 61326, and NAMUR Recommendation
NE 21, 1998.
•The manufacturer reserves the right to change the technical data in line with technical
progress at any time. You can obtain information on the current version of these
Operating Instructions and possible additions from your E+H sales centre.
1.4.1 Fail-safety
This instrument has been checked for protection against electromagnetic interference
in industrial use according to applicable European standards. It is protected against
electromagnetic interference by the following design measures:
•cable screening
•interference suppression filter
•interference suppression capacitors
#
Warning!
Protection against interference as specified above is valid only for an instrument
connected according to the instructions in these Operating Instructions.
1.5 Return
If the transmitter has to be repaired, please return it cleaned to the E+H sales centre
responsible. You can find the address on the last page of these instructions. For returns
please use the original packaging.
With the instrument, please enclose a completed copy of the "Declaration of
Contamination" form. You can find this at the end of these Operating Instructions.

4.1.3 Contact assignment
In the basic version, the Mycom S CPM 153 possesses 1 alarm and 2 additional
contacts. The instrument can be upgraded with the following additional equipment:
•3 contacts
•2 contacts and 1 current or resistance input (only for non-Ex)
•1 contact, 1 current input and 1 current or resistance input (only for non-Ex)
The available contacts can be assigned via the software (see the "PARAM" menu ➞ "Set
up 1" ➞ "Contacts" from page 36)
!
Note!
•If you use NAMUR contacts (acc. to recommendations of process control engineering
of the chemical and pharmaceutical industry), the contacts are set to the relays as
follows:
–Failure to "ALARM"
–Maintenance required to "RELAY 1" and
–Function check to "RELAY 2".
•You can assign up to three relays to the controller.

4.2.2 Changing the pH input from glass electrode to IsFET
sensor
With this device you can run the electrode types glass electrode / redox electrode or
IsFET sensors.
For adapt the electrical connection from glass electrodes to IsFET sensor CPS 401,
please proceed as follows:
1. Open housing cover of the CPM 153.
2. Pull off both ends of the red line to the pH input (s. Fig. 29, p. 105; line to
position 130).
3. Pin up the jumper on the back sides of the included terminals "DRN" and "SRC".
4. Remove the "pH" terminal out of the transmitter and replace it by the terminals
"DRN" and "SRC".
5. Change the setting "electrode type" in the Quick Setup menu (p. 27) to "IsFET".
!
Note!
Please switch from IsFET sensor to glass electrode correspondingly.
4.2.3 Outer screen connection
"
Caution!
Danger of inaccuracy.
Always protect plugs and terminals against humidity.

4.2.4 Cable extension
If a cable extension is necessary, use
•junction box VBM
and the following types of non-terminated measuring cables:
•for CPK 1, CPK 9: Cable CYK 71
•for CPK 6: Cable DMK
•for CPK 12: Cable CYK 12
4.2.5 Symmetrical or unsymmetrical electrode connection
!
Note!
The instrument is preset for symmetrical measurement (= with PML, potential matching
line). For unsymmetrical measurement, the setting must be changed accordingly (s.
page 32, Field A6, "Select connection type")..
Fig. 14: Left: symmetrical electrode connection
Right: unsymmetrical electrode connection
! Note!
With all cable types, the inner coaxial
cable has a black, plastic, semi-
conductor layer (arrow), which you
must remove.

Symmetrical (with PML) Unsymmetrical (without PML)
" Caution!
With a symmetrical connection, the line
to the potential matching pin (PML) must
be connected to the potential matching
terminal of the instrument. The PML must
always be in contact with the medium,
i.e. immersed in the buffer solution
during calibration.
If the instrument input is unsymmetrical,
pH measuring chains connected to
assemblies can be connected without
an additional potential matching pin.
If necessary, connect the available
potential matching pin to terminal PE.
Benefit of symmetrical connection
Measurement is easier under difficult
ambient conditions (e.g. strongly flowing
or high-impedance media or partially
soiled diaphragm).
Disadvantage of unsymmetrical
connection
The measuring chain reference system
has a heavier load, meaning that measu-
ring errors in limiting operating conditi-
ons are possible (see symmetrically
high-resistance instrument input).
Monitoring of the reference electrode by
the SC system (s. page 52) is not pos-
sible with unsymmetrical measurement.
" Note!
Do not connect the PML, otherwise there
can be shunt excitations.

4.3 Post connection check
After wiring up the electrical connection of the measuring instrument, carry out the
following checks:
Instrument status and specifications Note
Is the measuring instrument or the cable damaged externally? Visual inspection
Electrical connection Notes
Does the supply voltage match the specifications on the
nameplate?
100 V ... 230 V AC long-range
24 V AC / DC
Do the cables used fulfil the required specifications? Use an original E+H cable for
electrode and sensor connec-
tion, see "Accessories".
Are the installed cables strain-relieved?
Is the cable type route completely isolated? Along the whole cable length,
run the power supply and signal
line cables separately to avoid
any mutual influence. Cable
channels are best.
No loops and cross-overs in the cable run?
Are the power supply and signal cable correctly connected
according to the wiring diagram?
Are all the screw terminals tightened?
For connection with potential matching (PML):
Is the PML connected to the measuring medium?
! Note!
During calibration, insert the
PML into the buffer solution.
Are all the cable entries installed, tightened and sealed?
Cable run with "water sag"?
"Water sag": cable circuit han-
ging down so that water can drip
off.
Are all the housing covers installed and tightened? Check seals for damage.
