Tilt And Auxiliary Control

Pump Contactor Activated, T351 Full ON

When an operator calls for speeds 6 and 7, the logics activates the pump contactor by allowing current to flow from P2-17 through the pump coil, P214 back to battery negative. The contact tips close and the power transistors turn OFF. The pump motor is connected in series with the battery, applying full battery voltage. The shunt field is full ON during lift speed 6 and turned OFF during lift speed 7.
