5 - DAC 2X-2 Setup

DAC 2X-2 Mounting the Sensor

The sensor must be mounted with the writing facing upwards and the forward arrow pointing forward.

Bolts are preferred over Tek screws.

The DAC 2X-2 should to be mounted as close to parallel to the bottom of the shank as possible on a tile plow or the ground on a scraper or blade.

The DAC2X-2 should be mounted near the pivot point of the shank on a tile plow.  For readings only the sensor can be installed anywhere that tilts with the cutting edge as long as the arrow point forward and it is reasonably close to level.  For control it should be mounted close to the point where the control mechanism connects to the blade.  No matter where the sensor is mounted it needs to move in a 1:1 ratio to the cutting tip.

There are 3 cables needed to connect the slope sensor to the DAC.

6PFD-3PMD-CAB.  This cable connects to the DAC in the cab and extends to the hitch of the tractor.  Make sure to connect both the blue CAN connector and orange power connector.

6PMD-3PFD-PLOW.  This cable connects to the "CAB" cable at the hitch and to the adaptor cable for the sensor.  Be sure to route this cable where it will not get pinched and leave enough slack for the full range of travel of the equipment.

And one of the following:

CBL 300307.  Slope sensor adaptor for DAC2X-2.  Connects the "PLOW" cable to the sensor.

5P-SLOPE-6P.  Slope sensor adaptor for the original DAC2X.  Connects the "PLOW" cable to the sensor.

DAC 2X-2 Channel 2 Configuration

When using a slope sensor for control you must also tune Channel 2 on the DAC or performance will be erratic.  Choose the channel 2 radio button and repeat the "Minimum DAC Movement" steps.

DATA

There are 2 ways you can check the data being received by the DAC from attached sensors.  In DACCFG open the terminal screen and any data being sent to the computer will be shown.

From within SD Drain go to Settings -> DAC ->DAC Data.

Tare or "Zero" the Slope Sensor

In order for the slope sensor to work properly it must be calibrated for level to compensate for mounting surfaces not being 100% true.  On tile plows the point that is being read is the bottom of the boot and on blades it is the cutting edge.

On tile plows:

  • Fore slope or pitch control.

It is recommended to use a magnetic level that will attach to the bottom of the boot.  It is typically simpler to do this on a clean level pad.

Clean the bottom of the boot making sure there is no dirt that will cause the level to be off.

Attach the level to the bottom of the boot then move and use the hydraulics to move the boot until the level reads 0 then press the tare button for fore slope.  (TIP: Most tiles plows work better slightly nosed down.  This can be accomplished with a setting in the program or by setting the plow slightly nosed down before pressing the tare button)

Blades

  • Equipment capable of cross slope or roll control:

It is recommended to use a magnetic level that will attach to the bottom of the blade or controlled surface.  It is typically simpler to do this on a clean level pad.

Clean the bottom of the blade making sure there is no dirt that will cause the level to be off.

Attach the level to the bottom of the blade then move and use the hydraulics to tilt the blade until the level reads 0 then press the tare button for cross slope.

  • Tilt Compensation -- No control

This setting is used for tilt compensation of the GPS signal.  In most configurations there is at least one axis for which there is no hydraulic control.  For these applications the implement needs to be moved or lifted to obtain a 0 reading on the level.  Typically parking on a known level pad will work.

For cross slope the level reading can be taking either on a cross bar that is perpendicular to the implement or on the side of the GPS mast.  Since this reading is being used to compensate for the lean of the GPS globe the mast is the best place to take your readings from.  However it is simpler to see the level on a cross bar and in most instances this will work.  When you get the level reading 0 press the tare button for cross slope.
