Fixed Order Sequence

No rotation will occur. The loads will always have the same start and stop order. The next figure shows an example for 3 loads: LD1, LD2 and LD3. The sequence numbers are for LD1 = 1, for LD2 =2, and for LD3 = 3. If the requested number N of loads is 0, all loads are switched off. If the requested number N of loads is 1, only LD1 is in operation. If the requested number N of loads is 2, only LD1 and LD2 are in operation.
