6 K-BUS ERR (bottom right, 3rd row) | K-bus LED ERR | Lights up red: K-bus error - see K-bus error code |
K-bus error code
Error code | Error code argument | Description | Remedy |
---|---|---|---|
Persistent, continuous flashing |
| EMC problems |
|
3 pulses | 0 | K-bus command error |
|
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 nth bus terminal |
6 pulses | 0 | Error at initialization | Exchange Bus Coupler |
1 | Internal data error | Perform a hardware reset on the Bus Coupler (switch off and on again) | |
8 | Internal data error | Perform a hardware reset on the Bus Coupler (switch off and on again) | |
7 pulses | 0 | Process data lengths do not correspond to the configuration | Check the Bus Terminals for the configured Bus Terminals |
1..n | K-bus reset failed | Check the Bus Terminals |
