The Model DES520 is an Automatic Engine Control Module designed to automatically start and stop the engine. It will indicate the operational status and fault conditions, automatically shut down the engine and indicate the engine failure by a flashing LED on the front panel. Other simultaneous faults are indicated by steady LED.

Selected operational sequences, timers and alarms can be altered by the customer by using either the 807 hand held calibration unit or a PC and the 808 interface. This also provides the operator with ‘real-time’ diagnostic facilities to monitor the operation of the system either locally or remotely.

Microprocessor control allows for enhanced operation. The module features a comprehensive list of timers and pre-configured sequences. This allows complex specifications to be achieved
Configurable expansion facilities are provided.

Remote PC-controlled engine starting and stopping is also featured.

Operation of the module is via a three position rotary switch (key-switch option available) mounted on the front panel with STOP, AUTO and MANUAL positions.
