Transfer Switch Sequence of Operations

 

When the "Timing for Transfer" timer times out, the "Timing for Transfer" lights will switch from timing to complete and the main contactor will disconnect the load from the utility and move to the neutral position. With the Programmed Transition engaged, neither the utility nor the generator can supply the load.

The Programmed Transition module light will come on and the timer will begin to time from 1 to 60 seconds. This will prevent the main contactor from completing the transfer until the time delay lapses.

These lights should be on:
