Example Application: External Permit Closed Transition
In some ATS applications the customer may want to use an additional “Sync-check relay” in combination with
the DTSC-200A for highest system security. Only if the external sync-check relay sends a “Synchronism detect-
ed” signal to the DTSC-200A, then the in-phase monitor in the DTSC-200A shall be activated.
The “Enable closed transition” LogicsManager is the ideal function to carry out this functionality.

• Configure the LogicsManager for “Enable closed transition” in such a way, that the discrete input you
intend to use is setup here
