602 Fault tracing
8002 ULC overload fault
Programmable fault:
37.03 ULC overload
actions
Selected signal has exceeded
the user overload curve.
See A8BE ULC overload warning (page
583).
80A0 AI supervision
Programmable fault:
12.03 AI supervision
function
An analog signal is outside the
limits specified for the analog
input.
Check the auxiliary code (format XXXX
XYZZ). “Y” specifies the location of the
input (0: Control unit, 1: I/O extension
module 1, 2: I/O extension module 2, 3:
I/O extension module 3). “ZZ” specifies
the limit (01: AI1 under minimum, 02: AI1
above maximum, 03: AI2 under
minimum, 04: AI2 above maximum).
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.
