When the feedback signal
is > 4mA, the ”Warning” is automatically cleared.
Manual When Pr.08-09 = 1 or 2, AFE is a “Fault”. You must reset manually.
Reset condition Reset immediately
Record
When Pr.08-09 = 1 or 2, AFE is a “Fault”, and the fault is recorded;
when
Pr.08-09 = 3 or 4, AFE is a “Warning”, and the warning is not recorded.
