DPA WITH GPS ANTENNA

DESCRIPTION OF THE DPA BOX WITH GPS ANTENNA

• The DPA with GPS antenna regulates the flow of the distribution in relation to the advancement of the soil working tool (DPA system), continuously.
  
  
• The system uses a GPS antenna magnetised to the outside of the tractor cab.
  
  
• The GPS antenna DPA system is supplied with a control light and a control box in the tractor cab that incorporates the functions of the DELIMBE seeder. It is equipped with switches for memorising speed and starting seeding at the end of the row.

The DPA with GPS antenna includes:

• A control box with flow adjustment potentiometer,
  
  
• An on/off switch to control distribution,
  
  
• An on/off switch to control the blower/fan,
  
  
• A priming switch to start the system without moving forward (for example, to do your weighing),
  
  
• A memorised speed switch, to save a setting (the desired speed), 
  
  
• A magnetic GPS antenna for mounting outside the tractor cab, 
  
  
• Connection cable included with the box,
  
  
• A on/off switch, is included with the GPS antenna DPA box. This switch enables you to switch off the distribution at the end of the field and automatically switch it back on when you put the tool back in the ground.

HOW TO USE THE DPA WITH GPS ANTENNA

• Position the GPS antenna outside the tractor cab. When using this system, be careful to avoid areas with trees, mountains and white areas where the network is limited.
  
  
• It is preferable to use the adjustment table supplied with the machine to adjust the DPA.
  
  
• The on/off switch supplied should be positioned on the tractor's linkage. The linkage must come into contact with the switch. The switch is connected to a 3-pin socket on the side of the machine, in place of the plug socket.
  
  
  
  

DPA SETTING WITH GPS ANTENNA

Make the following calculation to obtain a setting in kg/hour:

Speed x Working width x Dose per hectare = Kilograms per hour.

The result obtained will enable you to weigh the machine in one minute to obtain grams/minute and check the correct dose setting. This weight must then be converted into kilograms/hour.

To do this, keep your finger on the priming ("amorcage") switch for one minute. The rotor will then rotate to the desired setting.

If over- or under-dosing is detected during weighing, the potentiometer setting must be changed, and weighing repeated.

Once a setting has been made on the potentiometer, turn on the on/off switches to start the blower and distribution. The tractor must be moving at the set working speed for the DPA to receive speed information. When this working speed is obtained, press the memorized speed switch just one time. The green LED starts flashing. When it lights up and stops flashing, this means that the DPA is working. The dose is even, whatever the tractor's forward speed.
