monitoring systems. However, using both pulse input ports for the
fuel log eliminates the possibility to also connect a speed log to the
pulse input port. You can still get speed input to the receiver using
the VHW NMEA-0183 data record in this scenario.
The receiver can also calculate your fuel consumption based on a
user input estimate, if you don't have any fuel sensors on board.
However, you do have to have some knowledge of what the normal
fuel consumption is. See the Fuel Mode below to implement this
feature.
Fuel Enabled:
Yes sets the receiver to look for data pulses on the Fuel input
port (refer to the Installation and Service Manual).
Fuel Unit:
Select between: Ton, Litre, US Gallon, or UK Gallon.
Low Fuel Alarm:
Select between Yes and No, the default is No. This choice works
in conjunction with Low Fuel Limit, below.
Low Fuel Limit:
Set to the low level (i.e. 1/4 of tank capacity, given in the proper
Fuel Units), the default is 0.0. This choice works in conjunction
with Low Fuel Alarm, above.
Fuel Mode:
Select between Constant and Flow Sensor, the default is
Constant.
Constant - allows you to program a continuous fuel flow, so you
can estimate your consumption if you do not have a real
time fuel flow sensor connected to the receiver.
