Analog Inputs

Overloading an analog input can lead to measurement errors!
A one-time overload of an analog input can cause a permanent, additional
deviation of up to 0.5 % of the full scale value. This may affect the safety
function!
Measurement accuracy can drop due to internal errors!
Due to internal errors, the measuring accuracy can drop to the value of the
safety-related accuracy without an error message being output. This may affect
the safety function!
Common mode voltage at the analog inputs is not monitored!
The F I/O module does not monitor the common-mode voltage at the analog
inputs. The user must take appropriate measures to ensure that the common-
mode voltage remains within the permitted range. Operation of the F I/O module
outside the allowed common-mode range may result in a greater measurement
error than stated in the specification. The measurement result can be corrupted!
Measurement accuracy can drop due to aging!
The measured value deviation due to aging specified in the technical data must
be taken into account in the accuracy analysis of the safety application.
