Section 55 - Electrical System, Controller - Chapter 1 AUXILIARY AUTO MODE SWITCH (IF EQUIPPED) Connecting the vehicle remote hydraulic system to one or more implement controllers will provide more efficient system control with less operator effort. The implement controllers generate a feedback signal to the AUX (remote) controller to request flow from the remote section to adjust the implement position. The AUX (remote) controller will provide flow through the corresponding remote section to position the implement, using the feedback signal, providing the operator with an automatic mode. MT05M005 This is a two position momentary type rocker switch that allows you to select the automatic or manual mode of operation on remote auxiliary valves No. 1 and/or No. 3 for use when laser operated or similar equipment is used. Depressing the No. 1 end of the rocker switch will turn the AUTO function ON for remote valve section No. 1. Depressing 1 again will turn the AUTO function OFF. Depressing the No. 3 end of the rocker switch will turn the AUTO function ON for remote valve section No. 3. Depress the switch again to turn the AUTO function OFF for remote No. 3. 55-1-11

Auxiliary Auto Mode Display Section 55 - Electrical System, Controller - Chapter 1 MT04M020 Remote 1 in Auto Mode Remote 3 in Auto Mode Remote 1 and 3 in Auto Mode RD05J003/004/005 AUXILIARY AUTO MODE DISPLAY When operating in the Auto mode it will be displayed on the programmable display screen in place of the PTO display. The hour meter in the bottom half of the display is visible at all times. All three display screens the operator will encounter when using the auxiliary mode switch are shown above. If both remote valves No. 1 and No. 3 are in the manual mode, the display will default back to the normal PTO display. The No. 1 and/or No. 3 digit is only visible if the No. 1 or No. 3 remote valve is in the AUTO mode of operation. NOTE: If equipped with the optional 6th and 7th remote valve, No. 6 will also be displayed if operating in the AUTO mode. Auxiliary Implement Connector 1 MK99K051 The auxiliary implement connector (1) for use with laser controls is located under the right rear corner of the cab. 55-1-12
