Error handling and diagnosis
Remedy
• Check power supply for overvoltage or
undervoltage 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)
Set manufacturer's setting with the KS2000
configuration software
Insert fewer Bus Terminals. The programmed
configuration has too many entries in the table
Software update required for the Bus Coupler
Check programmed configuration for correctness
Incorrect table entry
• 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.
Check whether the n+1 Bus Terminal is correctly
connected; replace if necessary.
Check whether the Bus End Terminal KL9010 is
connected.
Exchange the nth bus terminal
Exchange Bus Coupler
Perform a hardware reset on the Bus Coupler
(switch off and on again)
Perform a hardware reset on the Bus Coupler
(switch off and on again)
Set 1-8 to on or off, see BootP [} 25]
Perform a hardware reset on the Bus Coupler
(switch off and on again)
Perform a hardware reset on the Bus Coupler
(switch off and on again)
Start the Bus Coupler again, and if the error
occurs again then exchange the Bus Terminal
Start the Bus Coupler again. If the error occurs
again, restore the manufacturers setting using the
KS2000 configuration software
Start the Bus Coupler again. If the error occurs
again, restore the manufacturers setting using the
KS2000 configuration software
