CPC B64D 41/00 (2013.01) [B64D 11/04 (2013.01); G05F 1/625 (2013.01)] | 7 Claims |
1. A method comprising:
monitoring voltage across a normally closed (NC) throw of a first switch and a pole of a second switch for a first voltage anomaly;
monitoring voltage across a NC throw of the second switch and a pole of a third switch for a second voltage anomaly; and
monitoring voltage across a NC throw of the third switch and a pole of the first switch for a third voltage anomaly, wherein monitoring voltage for the first voltage anomaly is performed while a load is connected to the normally closed (NC) throw of the first switch, wherein monitoring voltage for the second voltage anomaly is performed while the load is connected to the NC throw of the second switch, and wherein monitoring voltage for the second voltage anomaly is performed while the load is connected to the NC throw of the third switch.
