OPERATION 3.9 STARTING THE ENGINES After starting observe the following: The ECS System monitors the Shovel’s functions and provides information about the appropriate operational data. If a FAULT message is displayed on screen (3), the acoustic warning signal (2) will sound simultaneously for approximately 1 second. In such a case proceed according to the instructions of the ECS system on page 80. Warning buzzer (2) will sound continuously when the hydraulic oil level is too low. In this case, stop the engines, locate and correct the cause immediately. Fill up hydraulic oil to the correct level. 9.
After warming up of the engines, the speed can be increased by setting switch (4) to high idle speed position. REMARK If one Engine fails to work during operation, the Shovel can be operated with the second Engine as an Emergency Measure, e.g. for moving the Shovel out of a Danger Area. Automatic Engine Shut-Down System (Safety Chain) The engine(s) will automatically be stopped or shifted to low idle speed as soon as one of the following FAULT or information con- ditions is being displayed on the ECS screen (3), illust. Z 21758: Start blocked by main shut-off valve *2) Start blocked by high pressure filter *1) Engine shifted to low idle: coolant temperature too high *1) Engine shutdown:
engine oil pressure too low *1) Engine shutdown: shut-off valve between main hydraulic oil reser- voir and suction oil reservoir closed. *2) Engine shutdown: overspeed *1) Engine shutdown: too high crankcase pressure *1) Engine shutdown: too low coolant pressure *1) Engine shutdown: emergency stop switch actuated *2) Engine shutdown:
fire in the power house *2) Faulty monitor channel for engine speed *1) Faulty monitor channel for coolant pressure *1) Faulty monitor channel for coolant temperature *1) Faulty monitor channel for engine oil pressure *1) Faulty monitor channel for hydraulic oil temperature *2) # No clearance for starting, shift engines to low idle speed *2) *1) Concerned Engine only *2) Both Engines REMARK If a fault message High pressure filter or pump restricted appears on display (3), the concerned engine will automatically be shifted to low idle speed. Never let the engines run with disconnected batteries. This may cause alternator damage. 215 CAUTION
