A Components of AML System

Signal names and functions

- Signal name: External indicator lamp (90% to 100%, yellow)

When the moment load factor is 90% or more and less than 100%, the yellow external indicator lamp lights.

Output condition:

(1), (2) and (3)

(1): Moment load ratio is 90% or more and 100% or less.

(2) 100% stop cancel indication (Di6) is "Not canceled" status.

(3): Anti-two-block cancel indication (Di5) is "Not canceled" status.

15 Do15-

When in the boom operation with jib elected (during main operation with jib elected), the yellow external indicator lamp lights when the moment load ratio described below is reached.

16 Do16-

Output when condition is met: OFF output

- Signal name: External indicator lamp (100% or more, red) When the moment load ratio is 100% or more, the red external indicator lamp lights. Output condition:

(1) or (2) or (3)

(1): Load factor exceeds 100%.

(2) 100% stop cancel indication (Di6) is "Canceled" status.

(3): Anti-two-block cancel indication (Di5) is "Canceled" status.

When in the boom operation with jib elected (during main operation with jib elected), the red external indicator lamp lights when the moment load ratio described below is reached.

Output when condition is met: OFF output
