program Revert to the manufacturer’s setting 9 pulses
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.
Note:
The power source to the power supply unit which is necessary to supply power to the CX-system, must not be
interrupted during operation. Switching off the supply voltage to the power supply unit refers here to the power supply
on the power contacts.

After a long flash (app.. 2 sec.) an IP-Link-Bus error has occurred. The following tables describe the error codes and
help to find the reason for the error. IP-Link errors most often turn out to be a result of inappropriate use of the optical
fiber.
