Pressure Rate and Boom Actuator Switches<br />
The pressure rate (increase/decrease) switch is located<br />
on the spray control console (Fig. 25). This switch along<br />
with the Manual Interface Module (or <strong>Pro</strong> Control, if<br />
equipped) changes the applied current to the PWM<br />
2<br />
valve which controls hydraulic flow to the hydraulic motor<br />
that drives the spray pump. Pressing the switch to the<br />
increase position allows additional current to the PWM<br />
valve which increases flow to the hydraulic motor. The<br />
4<br />
spray pump increases speed to allow additional flow<br />
and pressure from the spray pump. Moving the switch<br />
to the decrease position reduces current to the PWM<br />
valve and results in less flow and pressure from the<br />
3<br />
spray pump.<br />
The boom actuator switches are identical to the pressure<br />
1<br />
rate switch. These switches are used to operate the<br />
boom actuators to raise or lower the spray booms.<br />

1. Make sure ignition switch is off. Locate switch, remove<br />
console panel, and unplug wire harness connector<br />
from switch. 4 5 6<br />
2. The switch terminals are marked as shown in Figure<br />
26. In the INCREASE or boom raise position, continuity<br />
should exist between terminals 2 and 3 and also between<br />
terminals 5 and 6. In the neutral, center position,<br />
there should be no continuity between any switch terminals.<br />
In the DECREASE or boom lower position, conti- 1 2 3<br />
nuity should exist between terminals 2 and 1 and also<br />
between terminals 5 and 4.<br />
