Secondary Line) would have a Low Speed Shutoff set at
the speed at which the primary line nozzles reach their
upper limit (Maximum Pressure), eg 17kph.
For example if a Dual Line with 15 Primary Line section
valves and 15 Secondary Line section valves with separate
wiring was setup. Then the primary line valves 1 to 15
would have the Low Speed Shutoffs set at 2kph and the
secondary line valves would have the Low Speed Shutoffs
set at 17kph.
Low Pressure Hold
It is recommended that the Low Pressure Hold option be set
at '0.0' if using X20 Guidance with ASC. An alternative to this
would be to set a Min. Flow per Nozzle and Min. Flow for the
Regulator valve (refer Page 8-29 and 8-40)
A Pressure sensor would be required to set the Low Pressure
Hold.
The Low Pressure Hold is mainly designed for inline spraying
systems.
When using a Regulator Bypass system you will not be required
to set a Low Pressure Hold value, therefore the Low Pressure
Hold can be set at ‘0.0’.
The Low Pressure Hold is normally set at the speed just above
the point where the nozzles are at the bottom end of their range
eg.100kpa. To determine the Low Pressure Hold, the speed of
the Sprayer would have to be determined when the nozzles reach
Low Pressure Hold should be set to 0.0 for boom
testing and setup. When this is completed a Low
Pressure Hold can be set.
