Dual Relay box
Overview
The dual relay box has multiple functions to interface the aircraft and the pilot to the DynaNav system.
These functions are as follows: NOTE: THIS BOX MUST BE INSTALLED IN ALL INSTALLATIONS TO
PROTECT THE COMPUTER.
To interface to sense the spray on/off of the aircraft system.
To protect the DynaNav from the electrical spikes generated by the relay action
To protect the DynaNav system from static discharge on the control switches.
To interface multiple styles of control switch assemblies or to the ErgoGrip™ control grip.
Placement
The relay box is connected directly to the DynaFlight interface harness, From the relay box two harnesses
are connected, the spray on/off sense lines and the control switch module. This does not need to be hard
mounted, however for vibration isolation, it would be best to Velcro or dual lock it to any secure surface.
Wiring
The Dual Relay wiring harness has 3 sets of wires; Spray1 and Spray2. For most installations only Spray1
is connected to sense that the pilot is applying material. For Pressure switches on the Spray Boom, make
sure the pressure is well within the range of the normal boom pressure for spraying. The Cessna P/N S-
3010-1 Hobbs pressure switch can be adjusted to the right pressure. You can also use a Honeywell/Hobbs
P/N 76575 which is the same.
Wiring Harness Diagrams
Overview
The diagrams attached to appendix are for the interconnect wiring of the DynaNav system. All wires on the
harnesses supplied (except the control grip/box)
