LED Description/effect
E ON A cross-circuit with another input, an
external voltage or an external clock
output has been detected. The af-
fected input is kept in the safe state.
E ON An implausible signal change has
been detected at an input pair in two-
channel operation.
E ON A hardware fault at the reference
voltage source of the inputs has
been detected by internal selftest
mechanisms. As a result all inputs
are kept in the safe state.
E ON A hardware fault has been detected
at the indicated input by internal tests.
As a result all inputs are kept in the
safe state.

Errors: messages and removal
Acknowledgment/remedy
Read channel number via
DiagStateChannelNo object 0x033.
Check sensor, clock outputs, con-
nectors, and cabling.
This diagnostic message can be ac-
knowledged. Acknowledgment de-
letes the message and enables the
input and the assigned inputs.
If the error is still present, the
message is output again.
Read channel number via
DiagStateChannelNo object 0x033.
To reset the error state, both inputs
must be switched to the safe state. In
order to map a "1" signal for the af-
fected input pair, both inputs must
now be set (note negation for non-
equivalent inputs).
This diagnostic message can be ac-
knowledged. Acknowledgment de-
letes the message.
This diagnostic message can be ac-
knowledged. Acknowledgment de-
letes the diagnostic message.
Restart is only possible following an
error-free power up selftest.
If the power up selftest is not error-
free, the module must be replaced.
