Green LED ON (fixed) = Device active
L Yellow LED Fixed = L pre alarm (0,9 * I1 < I < 1,2 * I1)
L Red LED Blinking = L alarm (I > 1,2 * I1)
S Red LED Blinking = S alarm (I > I2)
L | S | I Red
LED Blinking = Parameters inconsistency - L = S or L = I.
LED Blinking without Parameters inconsistency = generic fault (please contact ABB)
