PadPuls M1
1 Functional description
The PadPuls M1 adapts consumption measuring instruments, such as, electricity, gas or water
meters to the M-Bus system. The meters that are to be adapted must have a floating pulse
output. The user can configure the PadPuls M1 with the MBCONF program so that the counted
3
impulses are converted to units such as kWh, m
, J and so on. With its user interface the
configuration of MBCONF is very easy.
When connected to the M-Bus the PadPuls M1 is powered by the bus. A built-in battery ensures
that metering continues even if the M-Bus fails for longer than the normal calibration time of the
water meter or heat counter. The battery also ensures that the meter readings and the
configuration data is maintained in RAM. Therefore the battery jumper should be plugged in at
all times. The jumper serves only to disconnect the battery from the circuitry if the battery needs
to be replaced.
Device data can be protected against unauthorized configuration. The PadPuls M1 can be
switched to protection mode with a special M-Bus telegram. In this operating mode, subsequent
changes to device parameters cannot be made. The protection mode can then only be disabled
by opening the sealable housing and pressing the unprotect pushbutton.
