Description Remedy
Persistent,
continuous
flashing
EMC problems • Check power supply for un
dervoltage or overvoltage
peaks
• Implement EMC measures
•If a KBus error is present, it
can be localised 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 KBus 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 re
maining Bus Terminals. Re
peat until the defective Bus
Terminal is located.
4 pulses 0 KBus data error, break behind
the power supply
Check whether the n+1 Bus Terminal is
correctly connected; replace if neces
sary.
n Break behind Bus Terminal n Check whether the Bus End Terminal
9010 is connected.
5 pulses n KBus error in register communi
cation with Bus Terminal n
Exchange the nth 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 cre
ated
Revert to the manufacturer's setting
which will clear the boot project.
14 pulses n nth 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 KBus data is no
longer correct
Start the power supply up again.
