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 electronic 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 longlife 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 fulfils the national and international requirements for interference resistance. To avoid malfunctions due to other interferences, do not install fluorescent 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 parallel 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.
