YES (ENABLED): The transfer switch will be permitted to transfer to the
Generator position.
5.10.23. EXTENDED PARALLEL TRANSFER (CTTS MODEL 4)
When the ATS is ordered with a Closed Transition soft-load option (i.e. ATS Model
Code Digit #13 “Operation Type” 4), the ATS can be operated in Extended Parallel
mode provided this programming feature is set to “YES” and the GHC (or external
switch) operation mode selection is set provided both power sources are available at
time of transfer. Note: the ATS will automatically revert to open transition transfer
mode should only 1 source of power be available at time of transfer. When this option
is set to “NO”, Extended Parallel operation is inhibited.
