About this document

The present user manual applies to communication units E65C CU-P40,

CU-P41 and CU-P42 –designated CU-P4x below.

This user manual supplements the operating instructions of the meter and

of the CU-adapter E65C CU-ADP2 and is incomplete without the data

contained therein. Together with these operating instructions, the user

manual contains all the information necessary for the operation of the

CU-P4x communication unit for the intended purpose. This includes:

Provision of knowledge concerning characteristics, construction and

function of the communication unit CU-P4x

Information about possible dangers, their consequences and meas-

ures to prevent any danger

Details concerning the performance of all work throughout the service

life of the communication unit CU-P4x (installation, commissioning,

operation, maintenance, shutting down and disposal)

The contents of this user manual are intended for technically qualified per-

sonnel of energy supply companies responsible for the system planning,

installation and commissioning, operation, maintenance, decommissioning

and disposal of the meters.

The technical data and the functional description of the communication unit

CU-P4x can be found in the following documents:

D000043185 "Technical Data E65C CU-P40, P41, P42"

D000011460 "Functional Description E65C CU A, B, M, G, D, P, E, Q"

1 Device description

1.1 Scope of application

The communication unit CU-P4x can be fitted in and removed from the fol-

lowing Landis+Gyr meters without opening the calibration seal:

Landis+Gyr E650 ZxD300/400xTindustrial and commercial meters

Landis+Gyr E850 ZxQ high-precision meters

Inserted in a CU-adapter CU-ADP2, the communication unit CU-P41 or

CU-P42 can also be used with other meters (e.g. Landis+Gyr E650

ZxD300/400xR, ZMD100AR, ZxB or meters from other manufacturers).

Connection to the meter is made in this case via an interface in the

communication unit (CS, RS232 or RS485).

1.2 Characteristics

The communication unit CU-P4x contains a built-in GSM/GPRS modem

(mobile telephone modem with GPRS service for data transmission in

packet form in GSM networks) and, depending on the version, an RS232-

and a CS interface (CU-P41) or an RS485- and a CS interface (CU-P42).

It is used to supplement the meters listed above.

The GSM/GPRS modem serves to read out or re-parameterise the meters

from a central station via the mobile telephone network with GPRS via the

Internet. It can also be used as a normal GSM modem.

The RS485 and CS interfaces can be used for connecting meter points

over a relatively long distance compared to RS232. The CS interface can

be parameterised as an active or passive interface and thus can be used

as master or slave as required with multiple connections.

If a communication unit CU-P41 or CU-P42 is used externally in a CU-adapter,

one of the existing interfaces of the communication unit is required for connec-

tion to the meter.

1.3 Type designation

The type designation of the communication unit CU-P4x is added to that of

the meter (see meter user manual), but is not shown on the main faceplate

of the meter. It is specified directly on the case of the communication unit

and can be seen through the front door of the meter through an opening on

the tariff faceplate.

The communication unit CU-P4x is available in the following versions:

1.4 Functions

A functional description of the communication unit CU-P4x is provided

separately. The following main functions are briefly summarised below.

1.4.1 GSM/GPRS modem

The mode of operation can either be parameterised as GSM modem or as

GPRS modem.

The GSM modem (GSM = Global System for Mobile Communication) is

approved according to various standards such as 3GPP release 4. It is a

wireless modem (Modulator-Demodulator) for the modulated remote

transmission of data via the mobile telephone network. The GSM modem

uses the 850 MHz, 900 MHz, 1800 MHz and 1900 MHz GSM frequency

bands.

The GPRS modem (GPRS = General Packet Radio Service) uses the

GSM network for data transmission, but sends and receives the data in

packets. The packet-oriented data transmission permits network usage

billing based on data volumes transmitted instead of connection time.

GPRS permits a wireless connection to the Internet by means of transmis-

sion protocol TCP/IP (Transmission Control Protocol/Internet Protocol).

1.4.2 CS interface

The serial bi-directional CS interface is standardised to IEC 62056-21 or

DIN 66258. It supports both the communication protocol to IEC 62056-21

as well as communication according to dlms and can be operated both

actively and passively.

1.4.3 RS232 interface

The RS232 interface is an asymmetrical, serial, asynchronous, bi-direc-

tional interface to DIN 66259. This interface can be used for the (tempo-

rary) connection of a PC or laptop, in order to communicate with the meter

independent of normal data acquisition. The RS232 interface of the com-

munication unit CU-P41 has no control lines (3-wire version).

1.4.4 RS485 interface

The serial bi-directional RS485 interface is standardised to ISO-8482. It is

basically intended for the connection of several meters (up to 31) using the

CU-P42 as the master.

8/40 Safety

2 Safety

2.1 Safety information

The following symbols are used to draw your attention to the relevant

danger level, i.e. the severity and probability of any danger, in the individual

sections of this document.

Danger

Identifies an extraordinarily great and immediate danger that could lead to

serious physical injury or death.

Warning

Indicates a potentially hazardous situation that may result in minor physical

injury or material damage.



Note

Indicates general details and other useful information to help you with your

work.

In addition to the danger level, safety information also describes the type

and source of the danger, its possible consequences and measures for

avoiding the danger.

2.2 Responsibilities

The owner of the communication units –usually the utility company –is

responsible for assuring that all persons engaged in working with meters:

Have read and understood the relevant sections of the user manual.

Are appropriately qualified for the work to be performed in accordance

with national regulations (see ISSA "Guideline for Assessing the Com-

petence of Electrically Skilled Persons").

Strictly observe the safety regulations (laid down in section 2.3) and

the operating instructions as specified in the individual sections.

In particular, the owner of the communication units bears responsibility for

the protection of persons, prevention of material damage and the training of

personnel.

For this purpose, Landis+Gyr provides training on a variety of products and

solutions. Please contact your local Landis+Gyr representative if interested.

2.3 Safety regulations

The following safety regulations must be observed at all times:

Changing of the communication unit or the 5 V supply in the terminal

cover used under special conditions or the GSM antenna must only be

made on meters not under voltage.

Only appropriate tools shall be used for the job. This means, e.g. that

the screwdriver must be of the correct size for the screws, and the

handle of the screwdriver must be insulated.

Devices which have fallen down should not be installed, even if no

damage is apparent, and should be returned for testing to an author-

ised service centre (internal damage possible).

Communication units must not be cleaned under running water or with

compressed air. Water ingress can cause short-circuits or damage

components.

Antenna installation must conform to instructions listed in this

document.

In addition, the safety instructions given in the user manuals for the meter

and the CU-adapter CU-ADP2 are also applicable.

The faceplate of the communication unit fitted in the meter is visible with

the meter front door open. When fitted in a CU-adapter, the faceplate can

be seen through the transparent front cover.

The external connections (supply voltage, antenna, CS- and RS485 or

RS232 interface) are situated underneath, while a 10-pin connecting plug

provides connection at the rear with the meter electronics or CU-adapter.

Four LEDs on the circuit board indicate transmission and reception activi-

ties as well as readiness to receive through the light guide under the face-

plate.

The communication unit has no seal of its own. It is secured when built-in

by a utility seal of the meter or CU-adapter.
