Fuel Manager Overview - Raymarine a65 Installation And Operation Instructions Manual

17.1 Fuel manager overview

The fuel manager provides an estimate of fuel remaining, and the
distance and time which can be travelled before the tanks are
empty. In order to calculate these values, you must configure the
total capacity of fuel available to the engines and log each time you
add fuel. The fuel manager also allows you to set a low fuel warning
alarm which is sounded when the vessel's estimated fuel falls below
a specified value.
The fuel manager page provides current calculation estimates and
controls to enable use of the fuel manager feature.

• Log each subsequent fuel fill whether partial or full.

Note:
Fuel manager estimates the amount of fuel onboard, based on
the user logging each time you fill up, the total fuel capacity, and
how much fuel is burned by the engine(s). Any incorrect entry
could dramatically affect the estimated fuel usage and capacity
which could result in a shortage of fuel. This system is not a
substitute for other types of fuel calculations.
Total fuel onboard is an estimate and will be inaccurate if fuel fills
are not entered, or fuel is used by other sources (e.g. generators
etc.). Estimated distance and time to empty will be based on the
fuel remaining calculation and values do not include weather/tide
effects.

You should not rely on the fuel manager calculations for accurate

Fuel logging
You must ensure all fuel fills are recorded using the fuel manager.
From the fuel manager page:
1. When filling the tanks until full select All tanks full.
The estimated fuel remaining is reset to the value of your fuel
tanks capacity.
2. When only partially filling the tank make a note of the volume of
fuel added to the tank and then select Add partial fill.
3. Enter the value noted earlier this will be added to your current
fuel remaining figure.
Note: It is recommended that you perform an 'All tanks full' fill
up as regularly as possible as partial fills will cause a higher
cumulative inaccuracy in the provided calculations.
Setting the low fuel alarm
Using the fuel manager also allows you to set a low fuel alarm
which, if activated, is sounded when your vessel's remaining fuel
falls to a specified value.
With the fuel manager turned on and set up correctly:
1. From the homescreen select Set-Up.
2. Select Alarms.
3. Select Fuel manager.
The low fuel alarm settings are displayed.
