VolvoPentaInterceptorSystem

The Volvo Penta interceptor system is a trim system that uses interceptors installed on the transom to act on a boat's running characteristics and provide a safer, more comfortable passage regardless of weather conditions.

The IS system affects a boat's running characteristics at speeds of ≈10 knots and above.

Each interceptor has a blade that extends by varying amounts, depending on the preferred effect, and trims the boat in three axes. The IS system is available in two versions, manual and auto.

Manual means the helmsman controls the interceptor blades using control buttons.

Auto means the system is pre-calibrated and interceptor blade control is completely automatic to provide optimum safety and comfort.

For further information refer to Operation page 56:

ATrimming angle of attack (the angle between the bow and the surface of the water). Improves the helmsman's visibility to provide safer passage.

BTrimming roll angle when moving dead ahead. Compensates boat heel to improve comfort e.g. when the boats is unevenly laden or in a side wind.

CTrimming roll angle in turns. Compensates boat heel, improves the helmsman's all-round visibility and provides for a more pleasant passage.

Operation

CAUTION!

Learn to manage the system and how it affects your boat in a safe and proper manner at calm conditions.

Aquamatic

In the case of aquamatic installations the PTA (Power Trim Assist) function is always switched on. Individual adjustment of the sterndrives is not possible.

Auto

Press the TRIM ASSIST button (1) to switch on the Auto function; The button's green lamp indicates that the function is on. The system now controls the interceptors automatically.

It is possible to switch between automatic and manual interceptor blade control in the Auto version. To take manualcontrol,switchofftheautofunctionbypressing the TRIM ASSIST button; when the button lamp is extinguished the function is off. The interceptor blades are now controlled entirely by the control buttons.

NOTICE! At start up, the system assumes the mode last selected, auto or manual.

The control buttons may be used to temporarily adjust boat trim even when the auto function is switched on. The auto function is still active but the system changes default mode. To revert to pre-calibrated auto mode, press the TRIM ASSIST button twice.

Manual control using control buttons

Manual control of the interceptors is performed using the control lever buttons and the buttons at the back of the control.

AAll interceptors are trimmed upward simultaneously. The bow is raised.

BAll interceptors are trimmed downward simultaneously. The bow is lowered.

CPort and starboard interceptors are trimmed upward individually. Used to correct heel.

DPort and starboard interceptors are trimmed downward individually. Used to correct heel.

If both the port and starboard buttons at the back of the control are pressed at once all interceptors are trimmed in the same way as when using the control lever button.

In installations with four interceptors, the interceptors are trimmed in port and starboard pairs.

Screen Display

Interceptor blade position, i.e. how far the blades are extended, can be presented in one of the EVC system displays. The display will also indicate if the system is in auto or manual mode.

In installations with four interceptors, the interceptors are presented in port and starboard pairs.

Cleaning

The system automatically performs self cleaning by extending and retracting the blades once every 24 hours to prevent fouling of the interceptor blades. Self cleaning is performed whether or not the boat is in use.

During prolonged inactivity, e.g. winter lay-ups, self cleaning can be switched off by turning off the circuit breaker or disconnecting power.

Starting

Make a habit of visually checking the engine, engine bay and transmission before start. This will help you to discover quickly if anything abnormal has happened, or is about to happen. Also check that instruments and warning displays show normal values when you have started the engine.

To minimize cold start smoke we recommend the installation of an engine heater or engine bay heater if temperatures below +5°C (41°F) are encountered.

WARNING!

Never use start spray or similar agents to start an engine. This may cause an explosion in the inlet manifold. Danger of personal injury.

Before Starting

• Check the engine and drive units oil level.

• Check the coolant level.

• Open the sea cock.

• Open the fuel cock.

• Turn the main switches on. IMPORTANT!

Never disconnect the current with the main switches when the engine is running. The alternator and electronics could be damaged.

• If the boat is fitted with an e-Key; unlock the EVC system with the e-Key.

• Start the engine bay fan, where fitted, and allow it to run for at least four minutes.

• Check there is sufficient fuel for the planned trip.

Starting the Engine

Shifting and adjusting speed is only possible at an active station. The main station is automatically activated when the EVC-system is unlocked with the eKey panel and the ignition is switched on.

On a boat with two or more stations the engine(s) can be started from another station with a start/stop panel – if the engine(s) are turned off. The station automaticallybecomesactivewhentheengine(s)is/arestarted.

Make sure the ignition is on

A green light in the IGNITION button indicates to ignition is on.

The ignition is switched on via the e-Key panel. Press the IGNITION button to switch the ignition on.

Put the gear in neutral

Put the drive/reverse gear in neutral by moving the control lever(s) to neutral at all stations.

Start the engine

Starting with the e-Key panel

Tostart,presstheSTART/STOPbuttononceforeach engine.

If the starter motor is engaged for its maximum activation time (30 seconds), the starter motor circuit is cut automatically to protect the starter motor from overheating.Ifpossible,leavethestartermotortocool for at least five minutes before making a new start attempt.

Starting with the start/stop panel

Press the starter button for each engine. Release the button as soon as the engine has started.

Read the instruments and warm the engine up

Allow the engines to idle for the first ten seconds. Check that instruments and warning displays show normal values.

Checkthatnomessagesaredisplayedandnowarning signs are showing. If a fault is registered, please refer to section Fault Handling page 68 for further information and recommended actions.

Warm the engine up at low speed and low load, so normal operating temperature is reached before full power is used.

IMPORTANT!

Never race the engine when it is cold.
