Diagnostics and error handling
BK3xx0 63 Version: 4.3.0
K-bus LEDs (local errors)
Two LEDs, the K-bus LEDs, indicate the operational state of the Bus Terminals and the connection to these
Bus Terminals. The green LED (I/O RUN) lights up in order to indicate fault-free operation. The red LED (I/O
ERR) flashes with two different frequencies in order to indicate an error. The errors are displayed in the blink
code in the following way:
Error type
Error code Error code argu-
ment Description Remedy
Persistent,
continuous
flashing - general K-bus error Check the Bus Terminal strip
1 pulse 0 EEPROM checksum error Set manufacturer’s setting with the
KS2000 software
1 Inline code buffer overflow Connect fewer Bus Terminals; too
many entries in the table for the
programmed configuration
2 Unknown data type Software update required for the
coupler
2 pulses 0 Programmed configuration

for correctness
n>0 Incorrect table entry Bus

comparison (Bus Terminal n) Correct table entry / Bus Coupler
3 pulses 0 K-bus command error No Bus Terminal connected;
attach Bus Terminals
One of the Bus Terminals is
defective; halve the number of Bus
Terminals attached and check
whether the error is still present
with the remaining Bus Terminals.
Repeat until the defective Bus
Terminal is located.
