Install Lift Switch (ADC2350 Only)
Refer to Figure 47
Lift switch components are shipped with the air cart. The
lift switch
turns the air cart seed metering on and off
as the NTA-3010/3510 is lowered and raised. The switch
is mounted at the upper end of the parallel arms on the
right rear wheel assembly.
When the NTA-3010/3510 is lowered, the upper parallel
arm contacts the flexible switch arm extension (whisker)
and operates the switch.
82. Select one:
464820520S1 DJ SWITCH SPDT W/WISKER & WIRE
The switch includes mounting fasteners. The bracket
is already installed on the drill, but may need some
adjustment.
Strain relief and wire must always point down to pre-
vent moisture from entering the switch. Switch mount
screws may need to be reversed to point wire down.
Rubber O-rings on the screws must be installed on
either side of the switch housing.
The whisker should extend over the upper parallel
arm enough so that the whisker cannot slip off the
arm when the drill is lowered, but not so far it bends
severely. To adjust, loosen the bolts attaching the
switch to the bracket and slide the switch left/right or
up/down as needed and re-tighten.
83. Select one:
467980474 8.5 EXTNSION CABLE CPC TO CPC
Connect one end of this cable to the lift switch cable.
Route the other end to the rear hitch. This cable is
secured with ties at a later step.
Note: For reference, the switch wiring is:
Black (switch) to black (extension)
Green (switch) to red (extension)
Switch open when drill is raised
The whisker should operate (start seeding) whenever the
openers are lowering into the ground. See the drill Oper-
ator manual for adjustment.
