The heater burnout current when there is a burnout at the common is as follows:
Heater burnout detection current = (10 + 5) / 2 = 7.5 [A]
The heater burnout current when there is a burnout at the load is as follows:
Heater burnout detection current = (10 + 0) / 2 = 5 [A]
To enable detection in either case, use 7.5 A as the heater burnout detection current.
