Screen Layout Overview

The Throttle Configuration interface consists of two main sections:

1. Tree Area

• Current Throttle Configuration Summary
  Refer to Figure 1.3
• 
  Displays an overview of existing throttle settings and arbitration method. Most fields are read-only except for the Number of Throttles field.
• Throttle #1 Setup
  Refer to Figure 1.4
  
  Throttle #1 can be configured using the following setup types:
  • No Throttle – Review or modify throttle settings.
  • Analogue and PWM – Modify settings specific to analogue or PWM signals.
  • Multi-position Switch – Select from one to four switch inputs for throttle control.

  Refer to Figure 1.5 – Multi-position Switch (2)
  
  Number of Switch Inputs:

  • 1 input = 2 positions
  • 2 inputs = 4 positions
  • 3 inputs = 8 positions
  • 4 inputs = 16 positions

  Refer to Figure 1.6 – Switch Input Configuration
  

• Throttle #2
  Only visible if a second throttle is configured.
• Arbitration Method Setup
  Only displayed if more than one throttle is configured.
  This screen lets you define how multiple throttle inputs are prioritized.Available Arbitration Methods:
  • Manual – User-defined control.
  • Summing – ECM uses the sum of throttle values.
  • Largest Wins – ECM uses the highest throttle value.

  Refer to Figure 1.7 – Arbitration Method: Largest Wins
  

2. Wizard Area

Located to the right (or below on smaller screens), the Wizard Area displays corresponding configuration details based on the Tree Area selection.

Available Buttons:

• <Back – Return to the previous screen.
• Next> – Proceed to the next screen.
