Error handling and diagnosis
BC5250 80 Version: 2.0.0
Error codes for K-Bus diagnosis
Error code Error code argument Description Remedy
0 - 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 0 EEPROM checksum er-
ror Enter factory settings with the KS2000 configuration software
1 Code buffer overflow Insert fewer Bus Terminals. The programmed configuration has
too many entries in the table
2 Unknown data type Software update required for the BX Controller
2 - reserved -
3 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 0 K-bus data error, break
behind the BX Con-
troller Check whether the n+1 Bus Terminal is correctly connected; re-
place if necessary.
n Break behind Bus Ter-
minal n Check whether the KL9010 Bus End Terminal is connected
5 n K-bus error in register
communication with
Bus Terminal n Exchange the nth Bus Terminal
6 0 Error at initialization Replace BX Controller
1 Internal data error Perform a hardware reset on the BX Controller (switch off and on
again)
2 DIP switch changed af-
ter a software reset Perform a hardware reset on the BX Controller (switch off and on
again)
7 0 Note: cycle time was
exceeded Warning: the set cycle time was exceeded. This indication (flash-
ing LEDs) can only be cleared by booting the BX Controller
again.
Remedy: increase the cycle time
9 0 Checksum error in
Flash program Transmit program to the BX again
1 Incorrect or faulty library
implemented Remove the faulty library
10 n Bus Terminal n is not
consistent with the con-
figuration that existed
when the boot project
was created Check the nth Bus Terminal. The boot project must be deleted if
the insertion of an nth Bus Terminal is intentional.
14 n nth Bus Terminal has
the wrong format Start the BX Controller again, and if the error occurs again then
exchange the Bus Terminal.
15 n Number of Bus Termi-
nals is no longer correct Start the BX Controller again. If the error occurs again, restore
the manufacturers setting using the KS2000 configuration soft-
ware
16 n Length of the K-bus
data is no longer correct Start the BX Controller again. If the error occurs again, restore
the manufacturers setting using the KS2000 configuration soft-
ware
