Operational State Diagram OFF The DCS is powered down and nothing is displayed.
Machine switched on (Power-up switch activated)
Methane Sensor Warm Up
If no further action is taken, the DCS will switch itself off. The operator may press UP to allow the engine to be started again, without having to wait for the DCS to restart and the Methane Sensor to warm up again.
The DCS will wait for some time after the engine is stopped, displaying information for the operator.
Engine Stopped
Manual No.M01335
Pre Run Check
The sensors are checked to determine if it is safe for the engine to start.
Ready to Start
The DCS waits to see if the operator starts the engine.
Engine Running
While the engine is running, the DCS continually monitors the sensors to ensure it is operating safely.
Fuel Cut Shutdown
If the engine must be stopped, the DCS cuts fuel to the engine. The DCS then waits to see if the engine stops.
Manual Shutdown
In all cases except Engine Running, the DCS will power itself down after a predetermined amount of time. This is to ensure the internal battery is not needlessly depleted.
