The PadPuls M2C is a two‑channel rail‑mounted pulse collector; this manual covers installation, configuration, operation, battery handling and technical data.
The PadPuls M2C pulse collector adapts floating‑pulse output meters (e.g., water, gas, electricity) to the M‑Bus system. It can connect up to two impulse meters, supports tariff switching, and includes a built‑in battery for uninterrupted metering when the M‑Bus fails.
The manual provides functional description, step‑by‑step installation and mounting on a DIN rail, parameterisation with the MBCONF software, battery exchange procedures, M‑Bus telegram handling, and a full set of technical specifications. This manual is written in German.

| Operating temperature | 0 to 55 °C |
| Storage temperature | -20 to 60 °C |
| Maximum pulse frequency | 14 Hz |
| Maximum cable length | 10 m (twisted pair recommended) |
| Standard battery | Lithium 3 V, 230 mAh |
| M‑Bus unit load current | ≈1.5 mA |
| Contact voltage | 2.5 V to 3.6 V |

The device can count pulses up to 14 Hz; higher frequencies may cause false counting.
With the standard 230 mAh battery the device can operate for about 18 days per year during M‑Bus failure (assuming 10 years of operation).
Activate protection mode via a special M‑Bus telegram; it can only be disabled by opening the sealed housing and pressing the unprotect button for at least 4 seconds.
