If user set target demand at 160 kW and AL1 is at 110
Then over load limit will be 160x110/100 = 176 kW
As the running load exceeds 176 Alarm1 will be ON.

be on full normal period.
Example:-
If user set target demand at 160 kW and AL2 is at 95
There limit for Alarm2 will be 160x95/100 = 152 kW
As Rising Demand (RD) reaching 152 Alarm2 will be ON.

If user set target demand at 160 kW and Trip is at 100
