The system then needs to know a few basic parameters for the installation.
Name – To aid identification, you can attach a specific name here.
Rated engine size – enter the kilowatt maximum engine output here.
Fuel tank size – In a single generator system with a connected engine ECU, the system can monitor
fuel usage and approximate tank levels, so enter the fuel tank size here.
Max engine RPM – enter the documented maximum engine speed here.
Min engine RPM – enter the documented minimum engine speed here. Some older or more basic
engines will slow down under load, so it is advised that you enter a number here slightly below the
documented tick-over speed.
Nominal temperature – the power output of the generator is limited as temperature increases. This
value is an approximate target temperature before power is limited. 100 degrees is a ‘safe’ value for
installations with poor airflow, 120 degrees is the suggested value for most installations, and 140
degrees is the maximum that should be allowed.
Pulley ratio – different engines and installations require different configurations of drive pulley. A
2.6:1 ratio is the most common for a standard Integrel setup, if this needs to be changed please
contact Integrel for advice.
Use CAN bus gear detect – a lot of more modern engine installations have a start-inhibit wired directly
into the engine ECU. If this is the case, enable this setting and the system will pick up the gear
position directly from the ECU data. Alternatively, leave this setting disabled and wire a throttle-lever
or direct gearbox switch back to the corresponding connections on the controller wiring loom for
direct gear position detection.
Propeller intercept RPM – For most installations this should match the maximum engine speed.
However, if the vessel has a non-standard propeller configuration it may stop the engine reaching full
speed. If this is the case, enter the maximum in-gear under-way engine RPM here.
Once all settings have been entered, press the ‘Upload’ button.
After all settings have been configured, it is important to exit the setup mode, otherwise the system will
remain in command mode and not generate under test. To do this, select ‘Realtime mode’ from the setup
menu.
If the system is left in setup mode inadvertently, power-cycling the Integrel system will return it to normal
mode of operation.
Once all the sensors and generators have been successfully configured, the engine may be started, and
commissioning tests begun.
