Sometimes an applicator is already equipped with an
electronically controlled flow control valve. If the valve
meets the speed and precision requirements of the
ARC system, it can usually be adapted for use. Check
with your MID-TECH
®
dealer, or the factory, about the
adaptability of a specific valve.
5. Boom Interface
The ARC control console must know what boom
sections are activated at any time, in order to adjust
chemical flow rates appropriately. The console
recognizes the status of as many as nine separate
boom sections, by monitoring the control signal to
each section. The console can also sense the operation
of an Implement Status switch which would result in a
selectable response by the flow control valve (position
held or full closure). Finally, the system can be
equipped with an optional Ground Speed Override
switch which, when activated, will cause the control
console, under certain conditions to use a pre-selected
"OVERRIDE SPEED” , rather than actual ground speed,
to control the application rate.
The standard ARC system is supplied with a five
position boom interface cable which plugs directly into
the rear of the ARC console and allows connection of
up to five boom control switches and one status
switch. An optional nine boom interface cable is
available for larger applicators.
An optional boom control switch box is available to
serve those sprayers not already equipped with boom
switches. Boom switch boxes are offered in three, five,
or nine boom configurations and they are complete
with wiring harnesses. The switch box also provides a
MASTER ON/OFF boom switch, a GROUND SPEED
OVERRIDE switch and acts as an interface for an
IMPLEMENT STATUS switch. The wiring harness
from the boom switch box plugs directly into the back
of the ARC control console.
