General information

With multipulse resp. multilog you have acquired

one of the most up-to-date and modern electron-

ic pulse counter modules currently available on

the market.

Expressive symbols in the display and easy

menu navigation make readout simple. It can be

operated with one single button. The change of

pulse values and the setting of the data loggers

with multilog is being done via the software GMM.

The pulse counter module is equipped with a long-

life battery made for operation during a period of 5

years including a reserve of at least another year.

With a second battery you will reach 11 years.

Electro-magnetic interference

multipulse resp. multilog fulls the national and

international requirements for interference resis-

tance. To avoid malfunctions due to other inter-

ferences, do not install uorescent lamps, switch

cabinets or electric devices such as motors or

pumps in the immediate vicinity of the meter

(minimum distance 1 m). Cables leaving the

meter should not be laid parallel to live cables

(230V, minimum distance 0.2 m).

Cables leaving the meter should not be laid paral-

lel to live cables (230V, minimum distance 0.2 m).

The device complies with Directive 89/336/EEC

(electromagnetic compatibility).

Care instructions

Clean plastic surfaces with a damp cloth only.

Do not use any scouring or aggressive cleaning

agents! The device is maintenance-free during

the service life. Repairs can only be made by the

manufacturer. The most up-to-date information

about this product and of our installation notice

can be found at www.zenner.com.

If water meters with a potential free reed contact

are connected to the inputs the connection can

be made in any direction.

The connectors are given twice for the incoming

and outgoing of the M-bus wires.

Depending on the pulse counter module’s model

the version of the connection board can differ.

Communication

The pulse values can be programmed via

the software GMM. The pulse value can

be called up in the display (see the display

overview, Level 1).

The display resolution should be chosen in

such way that the display can not overow

within one years time.

M-Bus (optional)

The optional M-Bus interface complies

with the norm EN 1434-3 and operates

with 2400 baud xed. It can be set to

300/9600 baud if necessary.

Subject to modications and errors excepted. Any liability for misprints excluded. SAP124288_121010_EN

Installation instructions

Safety instructions

The installation has to be done by qualied per-

sonnel. Read the instructions carefully right up to

the end before starting to mount the device.

The current laws and regulations regarding the

installation have to be observed

At devices with communication interfaces or

mains supply the general technical rules and the

correspondent regulations have to be followed.

General Information

Take care of:

■the display of the module must readable at all

times,

■to avoid malfunctions due to other interfer-

ences do not install uorescent lamps, switch

cabinets or electric devices such as motors or

pumps in the immediate vicinity of the module

(minimum distance 1 m),

■the ambient temperature must not exceed

55°C,

■the pulse value of the meter must correspond

with the one from the module.

The module has 7 cable glands for wires with a

diameter between 4,2 and 10 mm. Keep unused

glands closed. multipulse resp. multilog is deliv-

ered ready for operation. It does not need any set-

tings or adjusting.

ZE12B28_MA_Multipulse_EN_V2_D 7 10.10.12 17:24

Installation pulse counting module

ZENNER recommends to mount the module on

the wall.

Do not mount the device at the pipe or attach it

directly on the meter. The mounting adapter at

the backside of the module can be used for rail

mounting or for wall mounting.

For wall mounting detach the adapter and turn it

180°, attach the adapter with at least two screws

to the wall and clip the module on it.

For rail mounting lift the adapter a little bit, place

the module on the rail and push the adapter

back until it locks.

Connection meter

With mechanical meters the connection order is

optional. Mind the polarity at electronic meters.

External power supply

A small vertical line appears in the display when

the optional external power supply is on service.

In case of a failure of the external power sup-

ply the devices switches automatically to battery

supply.

The battery lifetime can be checked in the dis-

play (level 3). After having reached the date the

battery has to be replaced if needed.

Operation test

Check the pulse counter module for any error

codes in the display after installation (see table

for error codes).

Most of the errors can be deleted by pressing

the button. If the error appears permanently, it

will be detected at the next measuring cycle and

displayed again.

When attaching the top cover on the housing

pulses on the inputs can possibly be generated.

Check readings of the inputs and correct if nec-

essary.

Sealing

We recommend sealing the device with the in-

cluded seals to prevent unauthorized opening.

Maintenance

Repairs or overhaul are only allowed by the

manufacturer or companies authorized by the

manufacturer.

Status display / Error codes

The symbols in the table below show the pulse counting module’s operational status. The status

mes

sages only appear in the main display! The temporary display of the warning triangle can be caused

by special operating states and does not always mean that the device is malfunctioning. However,

should the symbol be displayed over a longer period of time you should contact the service company.

Error codes show faults detected by multipulse resp. multilog. If more than one error appears, the sum of

the error codes is displayed: Error 1100 = error 1000 and error 100.
