Electronic pulse counter module
with 3 inputs for connection
of meters with pulse outputs
All that counts.
General information Care instructions
Clean plastic surfaces with a damp cloth only.
With multipulse resp. multilog you have acquired Do not use any scouring or aggressive cleaning
one of the most up-to-date and modern electron- agents! The device is maintenance-free during

menu navigation make readout simple. It can com
be operated with one single button. The change
of pulse values and the setting of the data log-
gers 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 pe-
riod of 5 years including a reserve of at least an-
other year. With a second battery you will reach
11 years.
Electro-magnetic interference
multipulse resp. multilog fulfils the national and
international requirements for interference re-
sistance. To avoid malfunctions due to other
interferences, do not install fluorescent lamps,
switch cabinets or electric devices such as mo-
tors or pumps in the immediate vicinity of the
meter (minimum distance 1 m). Cables leaving
the meter should not be laid parallel to live ca-
bles (230V, minimum distance 0.2 m).

Status display / Error codes
The symbols in the table below show the pulse counting module’s operational status. The status
messages 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.
