ACI loss (ACE)

Analog input loss (including all the 4–20 mA analog signal)

Action conidition - When the analog input is < 4 mA (only detects 4–20 mA analog input).

When Pr.03-19 = 1 or 2, ACE is a “Warning”. When analog input signal is > 4 mA, the warning is automatically cleared.

When Pr.03-19 = 3, ACE is a “Fault”. You must reset manually.

ACI cable is loose or cut off - Tighten the terminal. Replace the cable with a new one.
