Installation and
operating manual
Electronic pulse counter module
with 3 inputs for connection
of meters
with pulse outputs
All that counts.
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 fulls 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).
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.
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).

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.
