A71C I/O Module internal
error
Calibration data is not stored in
the IO module. Analog signals
are not working with full
accuracy.
Replace IO module.
A8A0 AI supervision
Programmable warning:
12.03 AI supervision
function
An analog signal is outside the
limits specified for the analog
input.
Check signal level at the analog input.
Check the wiring connected to the input.
Check the minimum and maximum limits
of the input in parameter group 12
Standard AI.
A8A1 RO life warning The relay has changed states
more than the recommended
number of times.
Change the control board or stop using
the relay output.
0001 Relay output 1 Change the control board or stop using
relay output 1.
A8A2 RO toggle warning The relay output is changing
states faster than
recommended, eg. if a fast
changing frequency signal is
connected to it. The relay
lifetime will be exceeded
shortly.
Replace the signal connected to the relay
output source with a less frequently
changing signal.
0001 Relay output 1 Select a different signal with parameter
10.24 RO1 source.
