It may also be required that the system is disabled from running at certain times of the day or week. The XTM72C is designed to provide both of these requirements.

Channel 2 = GenSet change-over [ie: Midnight Sunday, 7 Days On Days Off] GenSet A GenSet B In Flip-Flop mode the relay changes state at each programmed transition from On to Off Thus, for the GenSets to changeover at mid-night each Sunday, program channel 2 On (for 1 hour) from Sat pm (23.00 hrs) to Sat pm (24.00 hrs). The duration of this On period is not important (and could be as low as 1 minute) but an hour is easier to program. E. & O. E. The Proven Solution to Power Controls DA01XTM1-1
