Diagnostic Functionon Volvo Penta Engine The purpose of the diagnostic function is to monitor and control the engine and EATS, as well as to protect components from damage. If a malfunction is detected the diagnostic function informs of the occurred fault in the form of a fault code. The fault code provides guidance when fault tracing. All fault codes and fault messages can be found in the Fault Code Register. The operator is warned that there is a malfunction via the instruments. Depending on the instrumentation in use, the fault message is shown in various ways. Fault codes can also be read out by the Volvo Penta diagnostic tool. Depending on the severity of the fault, the diagnostic function will take various actions to protect the engine (e.g. torque derate, idle speed only, engine shut down etc. ) DCU (Display Control unit) 1 When a fault is detected the following text is displayed: !! ENGINE WARNING !! alternating with Press SEL for information. 2 Reduce engine sp...

Installation checks for Volvo Engine Installation recommendations regarding each subject are to be found in the previous chapter. Refer to the relevant section to retrieve information so that the installation achieves a satisfactory standard. While the preliminary cooling system design is based on calculations, the suitability of any given system must be determined by actual tests. The tests must correspond to the most difficult operational conditions that may arise during use. Optional equipment specified by the original equipment manufacturer must be clearly defined and taken into account during the tests. Moreover, the checks and tests must include, and be adapted to, such equipment. For high altitude operations, there will be additional costs for the original equipment manufacturer in regard to certain applications. Experience has however shown that if customers are not able to clearly define and check which areas the equipment will be used in, Volvo Penta recommendation...

Information about compressed air filter All compressors supplied by Volvo Penta must be equipped with air filtration before the air inlet. Air filters are included in the compressor kit and can also be ordered separately. The compressor air filter must be changed at the same time as the engine air filter. The compressor inlet must be connected to the combustion air duct between the engine air filter and the turbocharger (if possible vertically from above). The connection point must always be positioned before the crank case ventilation connection to avoid the compressor drawing in oil. On the other hand, the distance to the turbocharger must be sufficient to prevent the pulsating compressor from affecting the turbocharger. The air inlet hose must have an inner diameter of at least 22 mm (0.87") and be suitable for hydraulic oil. When engine coolant is drained, the compressor cooling system must also be drained if there is a risk of freezing. Hydraulic Systems Gene...
