Error handling and diagnostics
LEDs for K­bus diagnostics
Error code Error code argu­
ment Description Remedy
Persistent,
continuous
flashing EMC problems • Check power supply for undervoltage or
overvoltage peaks
• Implement EMC measures
• If a K­Bus error is present, it can be
localized by a restart of the power supply
(by switching it off and then on again)
1 pulse 0 EEPROM checksum
error Revert to the manufacturer’s setting
1 Code buffer overflow Insert fewer Bus Terminals. Too many entries in
the table for the programmed configuration
2 Unknown data type Software update required for the power supply
2 pulses 0 Programmed
configuration has an
incorrect table entry Check programmed configuration for
correctness
n (n > 0) Table comparison
(Bus Terminal n) Incorrect table entry
3 pulses 0 K­bus command error • No Bus Terminal inserted
• 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.
4 pulses 0 K­Bus data error,
break behind the
power supply Check whether the n+1 Bus Terminal is correctly
connected; replace if necessary.
n Break behind Bus
Terminal n Check whether the Bus End Terminal 9010 is
connected.
5 pulses n K­bus error in register
communication with
Bus Terminal n Exchange the n th bus terminal
7 pulses 0 Process data lengths
of the set and actual
configurations do not
correspond Check configuration and terminals for
consistency
9 pulses 0 Checksum error in
Flash program Revert to the manufacturer’s setting
n (n>0) Bus Terminal n is not
consistent with the
configuration that
existed when the boot
project was created Revert to the manufacturer's setting which will
clear the boot project.
14 pulses n n th Bus Terminal has
the wrong format
Start the power supply again, and if the error
occurs again then exchange the Bus Terminal.
15 pulses n Number of Bus
Terminals is no longer
correct Start the power supply up again.
16 pulses n Length of the K­Bus
data is no longer
correct Start the power supply up again.
