System fault
The LED is lit, when:
• the CP is in the protected mode and an AS-i configuration error has
occurred (for example slave failed)
• the CP detects an internal fault (e.g. Flash-ROM defective)
• the CP cannot change to the mode requested with the "SET" button
(for example a slave exists with address 0).

Indicates that the CP has started up correctly.

AS-i Power Fail
This indicates that the voltage supplied to the AS-i cable by the AS-i power
supply unit is too low or there is a complete power fail.

Configuration error
This LED indicates whether the slave configuration detected on the AS-i
cable matches the configuration configured on the CP (LPS). If they do not
match, the CER LED is lit.

Autoprog available
In the protected mode of the CP, this indicated that automatic address
programming of a slave is possible. Automatic address programming makes
it easier to replace a defective slave on the AS-i cable.

Configuration Mode
This LED indicates the mode:
on: configuration mode
off: protected mode
