Transferred Back To Utility, Generator Shutdown - Generac Power Systems PWRcell Reference Manual

Section 8 PWRcell ATS
Utility Restored, Transferred Back to Utility – Generator Only Configuration
As the utility closing coil pulls the transfer switch to an "over center" position, the switch mechanically snaps to the
UTILITY position. Upon closure of the contacts to UTILITY, the limit switches (XA1 and XB1) mechanically actuate to
"arm" the circuit for the next transfer to STANDBY. When switch XA1 changes states, the circuit providing voltage to the
utility transfer coil is opened, and the coil de-energizes.

Transferred Back to Utility, Generator Shutdown

When the transfer switch returns to the UTILITY position the controller will shut the generator down after the one
minute engine cool-down timer expires.
NOTE: This is an example of Transfer Switch Operational Analysis. For troubleshooting use the operational analysis
with the appropriate wiring/schematic diagrams.
