DSE704

Auto Mains Failure control module

Features

The DSE704 is an Auto Mains Failure ControlModule 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.

OPERATION

The modules are operated using the three push buttons on the front:
 

  • MANUAL – This mode is used to manually start the engine.
  • AUTO – This mode is used to automatically start the engine. The module will be started by the remote start signal
  • STOP – This button is used to stop the engine when it is running in either manual or automatic mode.
