Utility Restored – Generator Only Configuration
Utility voltage is restored and available to terminals N1 and N2. The Utility voltage is "sensed" by the controller and, if it
is above 75% of nominal for 15 consecutive seconds, a transfer back to UTILITY will occur.
NOTE: The open contacts containing Wires N1A and 126 keep the switch from immediately transferring to the utility
position.
NOTE: This is an example of Transfer Switch Operational Analysis. For troubleshooting use the operational analysis
with the appropriate wiring/schematic diagrams.
