Operating the excavator in safety modes
Safety operation of the Diesel engine The engine can also be switched into safety operation automatically, as an example consecutively to a communication default in the control system. In safety operation, the engine works with reduced output in comparison with the normal operation. In safety operation the stop of the Diesel engine is achieved just like in normal operation, while turning back the ignition key to the "off" position. It is not possible to return to normal operation when the engine is running, the rocker switch S71 must be tilted back from safety operation into normal operation (position AUTO) only when the excavator is turned off. Notice! In safety operation, the communication between the electronic control box of the engine and the main circuit of the excavator may be no longer possible. The engine operating error codes are in this case no longer displayed on the screen. The occurrence of an operating error of the engine is then indicated as follows:
Caution! In case the warning light H60 lights up, the operator must shut the engine down as soon as possible and recognize which error has occurred. It's the operator's own responsibility to decide if the machine can be maintained operating or not! In safety operation the following functions remain available: coolant or of the charge air. the control box of the engine. At the opposite, the following functions are no longer operative: en the maximum permitted coolant or charging air temperature has been exceeded.
Diesel engine RPM adjustment in safety mode In normal operation, the desired value for the engine RPM is entered via the buttons S86, S228 and S229, and the engine speed is controlled in consequence by the electronic system of the machine. If the engine has been started in safety mode via the rocker switch S71 so it can be operated only with two different RPM values. The commutation between the two values is achieved via the switch S72.
