Transfer Switches Transfer Switch Equipment Utility—Generator Transfer switches are traditionally applied between a utility and a generator set for emergency and standby power systems. Generator—Generator Transfer switches are sometimes applied between two generator sets for prime power use, often in remote installations. In such applications, source power is periodically alternated between the generator sets to equally share run time.

Transfer Switches ATC Controllers In-Phase Transfer Feature Set 47D Closed Only ATC-800 controllers equipped with Feature Set 47D only transfer to an alternate source when both sources are synchronized. For synchronization to occur, both voltage and frequency differentials must fall within the user-selectable ranges. If synchronization does not occur (within a preselected amount of time), the controller will maintain load connection to the current power source and initiate an alarm.

Transfer Switches Standard and Optional Features 16.6 Feature Description Timers 1. Time Delay Normal to Emergency (TDNE) Provides a time delay to allow for the generator to warm up before transferring the load to the emergency source. Timing begins only after the Emergency Source becomes available and is deemed good based on the programmable voltage and frequency set points in the controller. 2. Time Delay Engine Start (TDES) Provides a time delay before initiating the generator start cycle.

Source 1—Monitoring and Protection Provides Source 1 monitoring and protection functions. If Source 1 fails, then the automatic transfer controller will begin the sequence of operations necessary to transfer the load to Source 2. All Feature 26 monitoring and protection functions are fail-safe operations. 26H.
Transfer Switches Standard and Optional Features 29J. Automatic Transfer or Automatic Transfer With NonAutomatic Retransfer Operation Provides a field-selectable programmable set point that permits the transfer switch to operate in one of the following two transfer modes (A or B): A. Fully automatic operation. B. Automatic engine/ generator startup and automatic transfer operation from Source 1 to Source 2.

Go to Emergency (Source 2) Provides the capability for an external contact closure to initiate a transfer to the Source 2 power source. This includes starting the generator, performing the programmed time delays and the transfer operation. Retransfer will occur when the external contact is opened. This is a failsafe function. 16E.
Transfer Switches Standard and Optional Features 16.6 16 32A. Time Delay Neutral Provides a time delay in the neutral position during the transfer and retransfer operations during which both Source 1 and Source 2 are disconnected from the load circuit. This allows inductive loads time to reach a safe voltage and eliminate back EMF. The time delay is programmable and is the same for both transfer and retransfer operations.
