What adjustment on an automatic transfer switch could be set to zero if the generator has a built-in shut down timer?

The engine shut down delay is an adjustment on an automatic transfer switch that can be set to zero when the generator has a built-in shut down timer. The purpose of this setting is to determine how long the transfer switch will wait before shutting down the generator after the utility power has been restored. If the generator itself has a built-in shutdown timer, it will automatically handle the timing for turning off, making it unnecessary for the transfer switch to incorporate any additional waiting time regarding engine shutdown. Therefore, setting this adjustment to zero allows for seamless integration with the generator's internal timer without any risk of conflicting timings or delays.

This understanding ensures that the generator operates efficiently and as intended, effectively optimizing the power transfer process between the generator and the utility supply.
