68 CX50x0 - Hardware Documentation
5 pulses n K-Bus error in register
communication with Bus
Terminal n Exchange the nth bus terminal
7 pulses 0 Process data length of the
configuration
(programmed) does not
match the terminal process
data length (terminals) Check the terminal configuration and the
terminals.
9 pulses 0 Checksum error in Flash
program Revert to the manufacturer’s setting
n (n>0) Bus Terminal n is not
consistent with the
configuration that existed
when the boot project was
created Revert to the manufacturer's setting which will
clear the boot project.
14 pulses n nth Bus Terminal has the
wrong format Start the power supply 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 power supply up again.
16 pulses n Length of the K-Bus data is
no longer correct Start the power supply up again.
Error code argument
The number of pulses indicates the position of the last Bus Terminal before the fault. Passive Bus Terminals, such as
a power feed terminal, are not included in the count.
In the case of some errors, rectification does not cause the power supply to leave the blink sequence. The power
supply can only be restarted by switching its supply voltage off and on again.
