CLEAN EFFICIENT POWERCLEAN EFFICIENT POWER2. FUNCTION OF HYBRID SYSTEM2.1. GeneralStarting procedure for the STEYR MOTORS Marine Hybrid Engine is the same for both cold and warm engines.The Engine Control Unit (=ECU) automatically regulates the fuel supply and the preheating period for anygiven temperature.Therefore the throttle lever should remain in neutral position.Hybrid Engines offer basically two different operation modes:• D-MODE for conventional operation of the combustion engineNOTE:If D-Mode is activated, SCC (=STEYR Control Center) displays system condition in menu “HCU” as followingillustrated:STEYR-CONTROL-CENTERR49.16.45N 48.08.56N 102.41.11W 014.27.47W 57,4 117 14:05 22:57GENER.SPEED/KN10.0 3410,51,5 rpm022 310rpm x 1000A455 3 4 43 85 4 85E-Mode ready26 °C bar 525D-Mode ready °C °C20 1090 86 HCU ok15050 120 6HCUOIL/BAR250250RPM2650 150050V01009870 131548,00E-Speed HCU/CURBATTERYHybrid statustus2,8 6.377.8 E-MOTOR 73TEMP/°C120MAINSWITCHGENER.Hybrid statusE-Mode readyD-Mode readyHCU ok11-013• E-MODE for electric operationNOTE:If E-Mode is activated, SCC (=STEYR Control Center) displays system condition in menu “HCU”as followingillustrated:STEYR-CONTROL-CENTER49.16.45N 48.08.56N 102.41.11W 014.27.47W 57,4 117 14:05 22:57GENER.SPEED/KN10.0 3410,51,5 rpm022 310rpm x 1000A455 3 4 43 85 4 85E-Mode ready26 °C bar 525D-Mode ready °C °C20 1090 86 HCU ok15050 120 6HCUOIL/BAR250250RPM2650 150050V01009870 131548,00E-Speed HCU/CURBATTERYHybrid statustus2,8 6.377.8 E-MOTOR 73TEMP/°C120MAINSWITCHHybrid statusE-Mode readyD-Mode readyHCU ok11-016Z001045-0_1_March 2012 - 13 -

2.2 Before Starting a Hybrid EngineFamiliarize yourself with the handling of the boat, in particular how to use transmission, and then proceed asfollows:1. Check the bilge for excessive water accumulation. Always keep the bilge clean and dry.Never allow the water level in the engine compartment to exceed the bottom of the oil pan. If water accumulationis unavoidable, install a bilge pump with an automatic control switch.For Hybrid systems ensure optically that all Hybrid Electrical Components (e.g. Generator, Hybrid Control Unit(HCU), U,V,W-cables etc.) are not affected by water.NOTE: The water level in the boat's engine compartment will increase when the boat is operated at a highincline before planing speed is reached. Excessive water accumulation in the engine compartment/ bilge maycause engine failures.2. Open the raw water intake valve for Diesel engine and Hybrid Cooling SystemNOTE: Operate the engine and Hybrid system only while the raw water supply is assured or the cooling systemis equipped with a fl ushing device. The engine- raw water pump and/or Hybrid electrical cooling pumps will bedamaged and/or will overheat if operated without cooling water.3. Open the fuel stop valve.NOTE: Only start the engine when a bubble-free fuel supply is guaranteed. Prior to fi rst start-up of theengine (after installation, after storage etc.), purge the fuel system by "ignition ON" for 6 x 10 sec.4. Check the operating levels of:* coolant* oil* hydraulic oil* transmission oil* Fuel5. Control electric system of EngineCheck charge state of engine’s starter battery.NOTE: Charge starter battery according battery manufacturers instructions. See therefor for Operation Manualof starter battery. Starter battery is not in scope of delivery from STEYR MOTORS!6. Check Hybrid system* Notice optically if protection covers are mounted on following components:11-011- HCU: cover U, V, W-protection cap B+, B-- Generator: cover U, V, W- Hybrid-Battery: Protection cap B+, B-11-00811-004NOTE: All parts supplied from STEYR MOTORS covered with protection- covers and accordingly signedcan be only opened, maintained and repaired from authorized technicans.* Check charge state of Hybrid BatteryNOTE: Hybrid Battery not in standard scope of delivery from STEYR MOTORSNOTE: If charging of Hybrid battery is necessary, proceed according Hybrid Battery manufacturers instructions.NOTE: If Hybrid battery charge state is above >57V, engine must be started with conventional startermotor(to start engine with conventional startermotor follow instructions as described in chapter 2.5- 14 -Z001045-0_1_March 2012

(The ECU will also reduce the engine power in case an important operating parameter limit hasbeen exceeded).* Indication Pre-warming Phase (combined indication through oil pressure light. Becomes affective ifambient engine coolant temperature is below 20 °C/68 °F)* Break – In; over load warning* Engine oil pressure too low* High coolant temperature* Sensors or sensor circuit defectAfter ignition is turned “ON” the indication/warning lights are illuminated and the warning horn will sound for lessthen a second (0.7 sec.) this serves as a functional check for the optical/audible warning system.The indication light and the warning horn remain switched on for 5 sec. after ignition “ON” if a sensor or sensorcircuit defect have been detected and stored in the Engine Control Unit (ECU).Please contact your nearest STEYR MOTORS Service Partner to get proffesional assistance to verify thedefi ciency and to correct any possible failure.If the engine oil pressure is too low, the warning light “engine oil pressure” lights and the audible alarm sounds.The engine power will be limited.In this case proceed as follows:* Check engine oil level, respectively add engine oil if necessary (refer to chapter Fuel and Lubricants)* Restart engine and watch the oil pressure light. The warning light has to extinguish within 3 or 4second after the start. If this does not happen the engine must be stopped immediately. (Ignition “OFF”)In case of an overheating of the exhaust gas cooling system, the warning light “engine control” fl ashes and theaudible alarm sounds (2 times per second); the engine power is reduced.In this case, proceed as follows:* IMMEDIATELY reduce the engine to idle speed.* Check and clean the raw water fi lter* Check the coolant temperature gauge for overheating of engine coolant. If the coolant temperaturegauge indicates overheating of engine coolant, switch for a short time to REVERSE to remove apossible clogging of the raw water inlet through large plastic parts etc., and then to FORWARD. Letthe engine run at idle speed for some minutes. If the temperature gauge still indicates anoverheating of the engine, the engine is to be stopped. Restart the engine only after having foundand eliminated the cause for alarm.

4.3. Reading Service Codes/Alarms from SCCWhenever the ECU transmits a service code or the SCC registers an alarm, the Alarmmenu button becomes red.By pressing this button one of two possible listswill be shown. This can be seen in the title: “Alarms from SCC” or “Service codes fromengine”.With this button you can switch between the two lists.If more events occur than can be shown at once, the up/down buttons can be used toshow all the entries.By pressing an entry line you can select single alarms / codes.The Clear button deletes the selected entry. Remark: If thealarm/service code still exists it will be added to the list again. In this case it seems asthough you can’t remove the entry. This is normal behavior.For deleting entries a password is required. Use the unit ID as password. The unit IDcan be found in the system information window of the settings menu. The passwordprevents unauthorized users from deleting entries. After leaving the alarms menu andreturning back the password is required again for deleting entries.Use this button to clear all entries of the shown list. Entries in otherlists remain preserved. If any alarm/service code still exists it will be added to the listagain. In this case it seems as if you can’t remove some or all entries. This is normalbehavior. For information about the password see paragraph “Clear button” above.When all alarms/service codes are removed, the alarm menu button appears in thenormal state orHelp screenTo get more information about the service codes from engine simply double-click onan entry. A help screen appears which provides you with more information about thisservice code.Z001045-0_1_March 2012 - 69 -
