EMC problems • Check power supply for undervoltage or
overvoltage peaks
• Implement EMC measures
• If a K-bus error is present, it can be localized by a
restart of the coupler (by switching it off and then
on again)
1 pulse 0 EEPROM checksum
error
Enter factory settings with the KS2000 configuration
software
(Menu "Online -> Coupler -> Services -> Factory
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 Bus Coupler
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 remaining Bus
Terminals. Repeat until the defective Bus Terminal is
located.
4 pulses 0 K-bus data error,
break behind the Bus
Coupler
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 K-bus error in register
communication with
Bus Terminal n
Exchange the n
th
bus terminal
14 pulses n n
th
Bus Terminal has
the wrong format
Start the Bus Coupler 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 Bus Coupler again. If the error occurs again,
restore the manufacturers setting using the KS2000
configuration software
16 pulses n Length of the K-bus
data is no longer
correct
Start the Bus Coupler again. If the error occurs again,
restore the manufacturers setting using the KS2000
configuration software
