Pump ModeSelect if the primary fuel pump is Digital (hard-wired) or CAN based, as well as Switched (simple on/off style) or Duty Cycle (variable duty).
Pump Override Switch EnableAllows an input to be configured that when switched on will turn the fuel pump output on.
Select an output for each fuel pump that is enabled, and an input for any override switches that are enabled.
PWM Signal Frequencyhe frequency that is used for the PWM signal.
Override Duty CycleIf Primary Fuel Pump Mode is Duty Cycle, this sets the duty cycle that the Primary Fuel Pump output will operate when the override switch is in the ON position.
Running two fuels pumps continuously, or a single very large flow-rate pump means excessive noise and heating of the fuel. A street vehicle with very high potential output will not need a large fuel supply at all times. The second pump would only be activated when load demands require that the extra flow be available.
The extra pump must be connected in parallel with the primary fuel pump. A check valve is necessary to prevent fuel from being forced in the wrong direction.
This node sets the operating settings for the Primary Fuel Pump output.
Trigger TypeSelect if the Aux Fuel Pump is triggered based on Load and RPM preconditions or Estimated Fuel Flow
Estimated Fuel FlowSets the flow threshold at which the Aux Fuel Pump is enabled if Trigger Type is set to Estimated Fuel Flow
RPM ThresholdSets the RPM at which the Aux Fuel Pump will switch on.
Load ThresholdSets the load at which the pump will switch on.
PWM Signal FrequencySets the frequency that the PWM signal is run. This is only available if the Aux Fuel Pump mode is Duty Cycle.
Time HysteresisSets the minimum time between successive on or off transitions.
Override Duty CycleIf Aux Fuel Pump Mode is Duty Cycle, this sets the duty cycle that the Aux Fuel Pump output will operate when the override switch is in the ON position.
The Fuel Pump Table controls the duty cycle for the output controlling the Fuel Pump. This table is only available when Fuel Pump Mode is set to Duty Cycle. Each Fuel Pump has its own table.
