Chapter 26 SCS 460 Serial Interface Installation & Service ManualPhoenix 10 Speed Sensors OnlyThe initial Speed Cal value for Phoenix 10 speed sensors is 785 [200]. After the initial console programminghas been performed, this value may be adjusted to optimize the system’s performance.Wheel Drive Speed Sensors OnlyImportant: This procedure should be performed only after the entire system installation is complete. Thisprocedure is critical to the console’s performance, so measure carefully. This procedureshould be performed on the same soil conditions in which you will be spraying, since wheelcircumference varies in soft soil versus hard-packed soil.FIGURE 2. Speed Cal Value Calculation1. Place a chalk mark or tape on the tire on which the speed sensor is mounted.2. Mark the spot on the ground directly below the chalk mark or tape.3. Drive the machine straight ahead, counting 10 full rotations of the wheel.Important: The mark must stop at the same position (with the chalk mark or tape perpendicular to theground at the bottom of the tire) as before it was before the measurement began.4. Measure the distance (in inches/cm) from the ground starting mark to the stopping mark. Round off fractionsof an inch/cm.5. Write down this number as it will be used as the Speed Cal value when programming the console.Note: Large tires and very low speed applications may require additional magnets to ensure accuratespeed readings. Any even number of magnets may be used as long as they alternate in color andare equally spaced. After calculating the Speed Cal value, the number must be adjusted accordingto the actual number of magnets used.For Example:Normal Number of Magnets x Calculated Speed Cal = Adjusted Speed CalActual Number of Magnets4 x 1200 = 8006 |
