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-200 for highest system security. Only if the external sync-check relay sends a “Synchronism detected”
signal to the DTSC-200, then the in-phase monitor in the DTSC-200 shall be activated.
The “Enable closed transition” LogicsManager is the ideal function to carry out this functionality.
Figure 2-5: Example application – external permit closed transition
Setup:
•
Parameter “Ext. permit for cld. trans.” must be set to “On” to activate this feature
•
Parameter “Transfer switch type” must be configured to “Closed”
•
Wire the relay output of the external sync-check relay to a free discrete input on the DTSC-200
•
Configure the LogicsManager for “Enable closed transition” in such a way, that the discrete input you
intend to use is setup here
Figure 2-6: Example application – LogicsManager
Explanation LogicsManager:
•
This LogicsManager becomes only active, if parameter “Ext. permit for cld. trans.” is set to “On”
•
If discrete input “6” becomes active, the LogicsManager output will turn into a logical “TRUE” state,
and activates the “In-Phase monitoring” of the DTSC-200
