PART 3
UTILITY RESTORED, RETRANSFER BACK TO UTILITY
As the utility coil pulls the transfer switch to an OVER CENTER position, the switch mechanically snaps to Utility.
On closure of the main contacts to the utility power source side, Limit Switches XA1 and XB1 are mechanically
actuated to “arm” the circuit for transfer to standby.
