Step 1. Initiating program Mode
Hold down the "S" button while turning the engine key to the "on" position until "L" starts to flash on the LCD.
1.
Step 2. Enter Low (L=Low) RpM
The "Low" setting is the RPM speed where the feed roller stops. The "up" arrow increases the RPM setting, while
the "down" arrow decreases the RPM setting. Setting the speed lower causes the engine to lug down more before
the feed roller stops.
Hold the appropriate (either up or down) arrow until the desired speed of 1400 RPM is displayed.
1.
Push the "S" button once with the desired RPM setting displayed to save.
2.
NOTE: DO NOT choose a setting equal to or below zero.
Step 3. Enter Normal (N=Normal) RpM
The "Normal" setting is the RPM speed the chipper rotor usually turns.
Hold the appropriate (either up or down) arrow until the desired speed of 1675 RPM is displayed.
1.
Push the "S" button once with the desired RPM setting displayed to save.
2.
Step 4. Enter High (H=High) RpM
The "High" setting is not needed with this application.
Set to zero (00) to deactivate.
1.
Push the "S" button once with zero displayed to save.
2.
Step 5. Enter Return (rEt=Return) RpM
The "Return" setting is the RPM speed where the feed roller restarts. The feed roller should restart before the rotor
reaches "Normal" RPM to maximize chipper efficiency.
Setting the speed higher allows the engine to recover more before the feed roller restarts.
Hold the appropriate (either up or down) arrow until the desired speed of 1425 RPM is displayed.
1.
Push the "S" button once with the desired RPM setting displayed to save.
2.
Step 6. Enter Number of poles (IpU=Number of poles)
The number of "Poles" is used to indicate the number of speed pickup devices.
Hold the appropriate (either up or down) arrow until one (1) is displayed.
