Liquisys M CXM 223 / 253 HART 1 Safety instructions
Endress+Hauser 5
1.2 Designated use
These Operating Instructions were specially designed for use with transmitters from the
Liquisys M CXM 223 / 253 family. They contain specific information on instruments
equipped with the HART®interface (Highway Adressable Remote Transducer). The
HART®interface allows the device to be operated via the handheld terminal DXR 275
or, using the operating programme Commuwin II, at a PC by means of a HART®modem,
e.g. Commubox FXA 191.
Any other use than the one described here compromises the safety of persons and the
entire measuring system and is therefore not permitted.
The manufacturer is not liable for damage caused by improper or non-designated use.
1.3 Installation, Commissioning, Operation
Please note the following items:
•Installation, electrical connection, commissioning, operation and maintenance of the
measuring system must only be carried out by trained technical personnel.
The technical personnel must be authorised for the specified activities by the system
operator.
•Technical personnel must have read and understood theses Operating Instructions
and must adhere to them.
•Before commissioning the entire measuring point, check all the connections for
correctness. Ensure that electrical cables and hose connections are not damaged.
•Do not operate damaged products and secure them against unintentional
commissioning.
•Measuring point faults may only be rectified by authorised and specially trained
personnel.
•If faults can not be rectified, the products must be moved from service and secured
against unintentional commissioning.
•Repairs not described in these Operating Instructions may only be carried out at the
manufacturer’s or by the Endress+Hauser service organisation.
1.4 Operational safety
The transmitter has been designed and tested according to the state of the art and left
the factory in perfect functioning order.
Relevant regulations and European standards have been met.
As the user, you are responsible for complying with the following safety conditions:
•Installation instructions
•Local standards and regulations

3.2 Post-installation check
After installing the transmitter, carry out the following checks:
Instrument status and specifications Note
Is the transmitter damaged? Visual inspection
Installation Note
Are the measuring point number and the labelling correct? Visual inspection
Process environment/conditions Note
Is the transmitter protected against rainfall and direct
sunlight?
For outdoor installation, the weather
protection cover CYY 101 is required,
(see Accessories).

4.1 Quick connection guide
4.1.1 Wiring diagram
Users have the following connection options at their disposal:
•Direct connection to the transmitter by means of current output 1
(terminals 31 / 32)
•Connection by means of the 4...20 mA circuit.
!
Note!
•The measuring circuit’s minimum load in current output 1 must be at least 250 Ω.

4.2 Connecting the HART®handheld terminal
DXR 275
You require the HART®handheld terminal DXR 275 for operation using a handheld
terminal. The HART®handheld terminal DXR 275 is connected via the current output 1
of the transmitter.
For connecting, please refer also to the documentation issued by the HART®
Communication Foundation, and in particular the booklet HCF LIT 20: “HART®,
A Technical Overview”.

passive input, 5 = HART®handheld terminal DXR 275
4.3 Connecting a PC with operating programme
You require a HART®modem Commubox FXA 191 for connecting a personal computer
with operating programme Commuwin II. The HART®modem Commubox FXA 191 is
connected via the current output 1 of the transmitter.
For connecting please refer also to the documentation issued by the HART®
Communication Foundation, and in particular the booklet HCF LIT 20: “HART®,
A Technical Overview”.

Note!
•The Commuwin II and HART®handheld terminal DXR 275 can only be operated
simultaneously if:
–one device is set as the primary master and the other as the secondary master
–neither master is constantly communicating.
4.4 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 Note
Does the supply voltage match the specifications on the
nameplate?
100 / 115 / 230 V AC
24 V AC / DC
Do the cables used fulfil the required specifications? Use genuine E+H cables for
sensor connection, see
Accessories chapter in the
standard Operating Instructions
Are the mounted 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
hanging down so that water can
drip off.
Are all the housing covers installed and tightened? Check seals for damage.
