1 Functional description

The PadPuls M1C serves for the adaptation to the M-Bus system of consumption
measuring instruments, such as, current, gas or water meters. However, the meters to
be adapted must either have a floating pulse output or an ouput according to DIN 43864
(S ). Only for usage of the S interface a power supply of 12V to 27VDC is necessary.

The user can configure the PadPuls M1C with the MBCONF program so that the
3
scanned impulses are converted to kWh, m , J and other units. The configuration is very
easy with the MBCONF user interface.
When connected to the M-Bus the PadPuls M1C is powered from the bus. A built-in
battery ensures that metering continues even if the M-Bus fails for longer than the
normal calibration time for the water meter or heat counter. The battery also ensures
that the meter readings and the configuration data is maintained in RAM. The battery
jumper should therefore be plugged in at all times. The jumper serves only to
disconnect the battery from the circuitry should the battery need to be replaced.
Device data can be protected against unauthorized configuration. The PadPuls M1C
can be switched to protection mode with a special M-Bus telegram. Subsequent
changes to device parameters cannot be made in this operating mode. The protection
mode can then only be disabled by opening the sealable housing and pressing the
unprotect pushbutton.
