FUEL LEVEL SENDER

[adzer]

hey, can anyone explain how to set up a fuel level sender on the pmu?

I'm guessing it involves using the table function but I'm not 100% sure

any help appreciated thanks

Hi,

There are two solutions for analog sensors:

1. If you are using the EMU BLACK
-Connect the sensor to one of analog inputs A9 - A16 (for example A9).
-Then enable Standard Stream in PMU (Use default ID 668 hex).
-The analogs A9..A16 will be automatically transmitted via CANbus to BLACK.
-You can then configure the Fuel Level table in the EMU BLACK software (for pin A9 in PMU - use the CANAnalog1 in EMU BLACK)

2. If you want to use it without the EMU BLACK
-In project tree: Add new Analog Input in PMU (name it, for example, a_fuelLevel), type: Analog sensor, min:0, max:5000, pullup:1MOhm. It will show you the value in miliVolts.
-In project tree: Add new Table in PMU: (name it, for example, t_fuelLevelPercent) Axis X: channel: a_fuelLevel, min:0, max:5000, step:500 (for example)
-Fill the table with values from 0 to 100.
-Important: the value of the fuel level in percent will be the value of the table (t_fuelLevelPercent)

-Please note, that if you are using the resistive sensor you need to attach external pullup (usually it's about 200-300 Ohm)

thanks for the reply, can you confirm the correct way to connect a 2 wire level sender into the pmu?

would it be the same if using it via the pmu or via the emu black or would it need wired differently?

I was going to wire 1 pin from the sender to sensor ground, the other pin to an analouge input, then connect +5v from the pmu to the wire from the sender going into the analogue with a 1k ohm resistor inbetween.

but after your reply I'm guessing its not that big a resistor?
