im not located in USA - and raymarines discriminatory forum policy prevents me from posting
questions, my local country has no such forum... so im stuck with no easy way to seek answers
(really bad customer support/ policy raymarine!!)
LH3 manual (advanced) lists possible data items for dashboard display.
however no details provided.
some items are obvious, others less so.
not obvious which are calculated items and which are simply display N2k Respective PGN data.
in particular, no details on
rate “ vs “engine fuel
presumably the latter is “instantaneous... but unclear if the average
is calculated by LH3 (& if so over period?) or is expecting an average rate supplied by engine
“instantaneous fuel economy “ ... presumably this is fuel rate (instant)
diviided into speed? (SOG?) or perhaps it uses LH3 average SOG (once again no details on period used for averaging SOG)
Fuel category (tanks)
“fuel economy” ?
what is this at a tank level?
“fuel rate total” ?
do above require tank fuel flow sensors?
Fuel category (all tanks)
“engine economy total”
is this summed fuel rate for all engines divided into SOG?
instantaneous or average?
does it require fuel tank
flow sensors? or does it use engine fuel rate?
“fuel flow total” .. presumably needs tank flow sensors?
I have 2 x engines, each report instantaneous L/hr (engine displays)
two fuel tanks
but single fuel tank
level sensor (only) .. no tank fuel flow sensors
as yet i dont have engine gateways (J1939 to N2k) installed,
and trying to understand what data items will be displayed on axiom (LH3) MFD
if i do purchase/install gateways
any help or experience with LH3 and data items appreciated..
or perhaps someone can post my above question (minus my stab at raymarine
support) into raymarine
