UltraShift ASW Auto Neutral Feature
Electrical Interface Requirements
All devices mounted on the vehicle that require Auto Neutral function from the Fuller
®
UltraShift ASW transmission must provide
an electrical interface with the transmission. A switch must be used to activate the Neutral mode of the transmission. This feature
uses pin A1 and B1 of the 30-way push button connector. See the figure below for electrical interface diagram.
Features
When engaged (switch closed), this feature causes the transmission to neutralize when the vehicle is stopped (i.e. stationary PTO
operation) and a transmission gear engagement cannot be selected. When disengaged (switch opened), normal transmission
gear engagement can be selected.
The Fuller AutoShift ASW transmission must have an input signal from the device to activate this feature.
The input signal wires must be isolated from other related circuits.
