K-bus

The power supply unit checks the connected Bus Terminals for errors. The red LED "K-bus ERR" is off if no
error is present. The red LED "K-bus ERR" flashes if Bus Terminal errors are present.
Table 16: Diagnostic LEDs in K-Bus mode.
Display
The frequency and number of the flashes can be used to determine the error code and the error argument.
An error is indicated by the "K-bus ERR" LED in a particular order.

Count how often the red LED K-bus ERR flashes, in order to determine the error code and the error
argument. In the error argument the number of pulses shows the position of the last Bus Terminal before the
error. Passive Bus Terminals, such as a power feed terminal, are not included in the count.
