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)

- 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.
