PAGE 4
Evaluation of consumption data The data are made available via the RS-232 port where they can be read out with the help of appropriate software, either directly or via modem. If a billing file is required, the M-bus central unit OZW10 can be used. Digital inputs The OZW111 has 2 digital inputs for the connection of potential-free contacts. The operating action of the contacts (active closed or active open) can be parameterized.
PAGE 5
LED for alarms The red LED shows the alarm status of the M-bus central unit: • LED dark: no fault and no alarm • LED lit: fault of one or several M-bus devices present • LED flashes: internal fault of M-bus central unit or signal at the digital inputs RS-232 selector This selector is used to select whether the M-bus central unit is connected to the RS232 port via modem or directly to the PC.
