Realizing Special Functions
Enabling a Delayed Transition via Key Switch
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
Sometimes it may be necessary to install a key switch for selecting the transition mode. This may happen if the
utility provider prevents a "parallel operation" i.e. an operation with a closed transition switch.
In this case it is possible to install a key switch, which is wired to a discrete input (in this example DI 6) of the
DTSC, in the front panel.

The
LogicsManager
function "Delayed mode active" must be configured to this discrete input to become TRUE
as soon as this DI is energized (key switch is turned to "Delayed").
