Automatic Transfer Switch Controller

The DSE327 is an Automatic Transfer Switch Control Module designed to monitor the voltage of an incoming AC supply from two different sources. This could be from both generator or mains (utility), or a combination of both. The module monitors S1 (Source 1) and in the event of a failure issues a start command to S2 (Source 2). The DSE327 can be ordered in 110 V and 230 V variants.

Activation of an input configured to mains load inhibit or generator load inhibit inputs cause the corresponding breaker to be opened immediately. No other change in function will occur. 

When the input is deactivated the load transfer scheme is followed as below. 

If an input configured to  Load Shed is activated, outputs set to Open Mains and Open Gen will energise, and inputs configured to Close Mains and Close Gen will de-energise. Open Mains Pulse and Open Gen Pulse outputs will only energise if the corresponding supply was on load before application of the Load Shed input. When the Load Shed input is deactivated, the load will be transferred back to the supply that was disconnected before application of the input. 

When the load is about to be transferred, the check sync function is activated. When the mains and generator are within the phase and frequency window the module transfers the load as shown below. 

The module waits indefinitely for synchronisation unless Return to programmed transition is active in which case after 2 minutes it performs a non-sync transfer as described in the previous section.
