6.3.3 Data
Orange light emitting diode which flashes when an M-Bus slave sends data to the master. The duration depends on the
amount of data being sent.
6.3.4 Overload
Red light emitting diode which flashes when the load on the M-Bus network is between 375 and 500 mA.
It is permanently lit when the load on the M-Bus network exceeds 500 mA. 375 mA corresponds to 250UL (M-Bus Unit
Loads). At 500 mA M-Bus Master MultiPort 250L disconnects due to overload or short circuit condition.
