The DSE720 is an Automatic Mains Failure Control Module that offers an advanced range of engine monitoring and protection features. The module has been designed to monitors a mains supply and switch over to the generator when the mains power fails. The module monitors generator frequency, generator volts, generator current, engine oil pressure, engine coolant temperature, engine running hours and battery volts. The module also displays the engine speed. When the module detects a fault condition it automatically shuts down the engine and indicates the exact fault on the modules LCD display or relevant LED indicator. The module can be configured using the front panel or via the DSE810 interface and a PC. The module can also be controlled from a PC that is located up to 100 metres away.
