light is on.

▪ When the actual load is>90% and≤100%, the yellow light is on, the alarm light flashes and sends out intermittent sirens.

▪ When the actual load reaches 100% of rated load, the red light on, the alarm light flashes and sends out continuous sirens.

▪ When the actual load is 102% of rated load, the system will automatically cut off the crane’s dangerous operation.
