Operations NOTE: The flashing yellow N (Neutral) lamp can indicate status of either Shift Disconnect (SD) or Split Range Throttle (SRT). Please exercise caution when engaging/disengaging either of these modes! A steady- on Neutral lamp ALWAYS indicates engine is in NEUTRAL. Shift Disconnect (SD): Flashing yellow N (Neutral) lamp indicates SD engaged for this engine. Allows throttle control without gear engagement. TO ENGAGE Shift Disconnect: Move engine’s lever to the “Neutral” position. Press the N (Neutral) button next to this lever. (Yellow lamp flashes.) To Disengage Shift Disconnect: Return engine’s lever to the “Neutral” position. Press N (Neutral) button next to this lever.
The yellow N (Neutral) lamp will go steady - SD is disengaged and the engine and transmission will now respond to lever commands. Split Range Throttle (SRT): Flashing yellow N (Neutral) lamp - SRT engaged for this engine. Provides greater throttle sensitivity: moving an engine’s control lever to “Full Forward” will only produce the maximum percentage of WOT (Wide Open Throttle selected at set-up - default Throttle Limit is 25%) TO ENGAGE Split Range Throttle: Move engine’s lever to Forward Idle position. Press N (Neutral) button next to this lever. (Yellow lamp flashes.) TO DISENGAGE Split Range Throttle: Move engine’s lever to Forward Idle or Reverse Idle.
Press N (Neutral) button next to engine lever. The yellow N (Neutral) lamp will go out - SRT is disengaged. Electronic Control System: Operation Manual for BY Series Engines with Unlimited Controls © Yanmar 2008 Page 13
