The height switch on the left operator station for the screed controls the height of the left extender. The height switch on the right operator station for the screed controls the height of the right extender.The machine electrical system provides power to contact "5" of the left height switch and contact "5" of the right height switch, through the 119-PK wire. Contact "2" of the left height switch and contact "2" of the right height switch are connected to ground through the 200-BK wire.When the height switch for the left extender is in the INCREASE position, contacts "1" and "2" of the switch are closed, and contacts "4" and "5" of the switch are closed. Power transfers from contact "4" of the switch to terminal "2" of the extender height motor through the C797-YL wire. The ground path from terminal "1" of the crown motor is provided through the C796-OR wire, across contacts "1" and "2" of the extender height switch, and through the 200-BK wire.When the left extender height switch is in the DECREASE position, contacts "3" and "2" of the switch are closed, and contacts "6" and "5" of the switch are closed. Power transfers from contact "6" of the switch to terminal "1" of the crown motor through the C796-OR wire. The ground path from terminal "2" of the extender height motor is provided through the C797-YL wire, across contacts "3" and "2" of the extender height switch, and through the 200-BK wire.When the right extender height switch is in the INCREASE position, contacts "1" and "2" of the switch are closed, and contacts "4" and "5" of the switch are closed. Power transfers from contact "4" of the switch to terminal "1" of the extender height motor through the C799-BU wire. The ground path from terminal "2" of the crown motor is provided through the C798-GN wire, across contacts "1" and "2" of the extender height switch, and through the 200-BK wire.When the right extender height switch is in the DECREASE position, contacts "3" and "2" of the switch are closed, and contacts "6" and "5" of the switch are closed. Power transfers from contact "6" of the switch to terminal "2" of the crown motor through the C798-GN wire. The ground path from terminal "1" of the extender height motor is provided through the C799-BU wire, across contacts "3" and "2" of the extender height switch, and through the 200-BK wire.Slope Control for the Extender
