The DSE4120 is an Auto Mains Failure Control Module that offers an excellent range of engine monitoring and protection features. The module has been designed to monitor engine temperature, low oil pressure, fail to start, charge failure, over speed and under speed.

When the module detects a fault condition it automatically shuts down the engine. The module also includes two user configurable auxiliary inputs.

The DSE4120 module also includes a tamper proof engine hours counter, engine exercise mode function and the enclosure has a closed back.

The module has been designed to automatically start the generator when the mains (utility) power fails.
As soon as mains (utility) power is restored the modules have been designed to transfer the load back to the mains (utility) supply. The module then instructs the engine to begin the cool down procedure and stopping sequence (user configured).
