ELECTRONIC ENGINE - LOGIC

Engine Protection System

The engine protection system monitor's temperatures and pressures and registers diagnostics failures whenever a abnormal operation condition occurs.

In this case, the engine power starts to decrease and the operators is warned by the stop indicator or warning indicator.

When this condition happens, the operator must stop and park the machine in order to prevent damage to the engine.

IMPORTANT

Do not Shut-off master switch, with starter key in the “start” position, error code 434(lack of energy to electronic engine controller) will come on. This error code will not affect engine operation, however it will be stored in the memory.

Stop by protection

Then engine stops automatically when one of the temperature, level or pressure sensors detect that the engine is operating in a below or above the normal operation conditions.

The stop indicator will flash for a 30 seconds to warm the operator.

Inlet air heating

The engine admission inlet air is heated when the engine is started in cold whether conditions, resulting in better starting and reduction of white smoke.

The indicator ligth at the instrument panel indicate when starting of the of the engine is possible.

The ECM (Engine Control Module) determines the heating total time based on the inlet manifold temperature (pre heating).

Once the engine is started, the air heater will be on until the inlet air temperature and cooling fluid temperature reach the required values.

The heater is swiched off whenever one of the following situations occur:

- Heating time exceeds 11 seconds; -The inlet manifold temperature is greater than 190C.

Water in fuel detector sensor.

When there is water in the filter housing, the indicator ligth will flash, indicating that the water should be drained.

Troubleshooting codes

Operation failures are identified by failure codes, that are registred and shown by the control system.

These failure codes are shown using indication at the maintenance panel.

NOTE: The failure codes do not cover all faillures that an engine may have. There are 2 kinds or faillure codes; The faillures codes from the electronic fuel system and the engine protection faillure codes.

Maintenance panel.

The manintenance panel indicates the operator when a minatenance operation is necessary(like engine oil change interval).

NOTE: Problems with the VSS(Vehicle Speed Sensor) or with the batteries may influence the data shown by the maintenance panel.

Indicators ligths.

A B C D E F

(A) - Warning light (yellow) indicates a problem that may be verified by the operator. Does not required imediate stop of the machine.

(B) - Stop ligth: (red) indicates a serius problem with the engine. Requires imediate stop of the machine.

(C) - Mantenance ligth: Indicates that an engine maintenance operation must be performed. The system monitors the distance and time that machine has been used.

(D) - Start ligth: The operator must wait until this light turns off to start the machine.
