This is done by adding a second ECU (Electronic Control Unit) in series with the existing ECU on the air seeder cart. This second ECU connects to the existing NH3 control system. The included harnesses connect directly to Raven Boom harnesses.
Raven harness part #’s that are required when connecting to Bourgault NH3 auxiliary rate control adapter harness for the Topcon Apollo system are:
- 6-section: 115-0171-838
- 8-section: 115-3001-083
- 9 or 10-section (depending on master valve set-up): 115-3001-185
- Full 10-section: 115-3001-209
When ordered with an air seeder it gets factory installed on the air seeder tank. It connects to the main ECU on the air seeder, and then harnesses run to either the front or back of the air seeder tank, depending on seeding system configuration.
The Bourgault Seed Rate Controller software on the X35 is capable of controlling NH3 by turning sections on and off as required to get full coverage of the field.
NOTE: A signal better than WAAS is recommended.
