Liq: Monitor Operation (Option)
Refer to Figure 42
With the optional hydraulic drive pump, the optional
SCS 450 console monitors fertilizer flow, field speed, and
manifold pressure. It operates the control valve to deliver
fertilizer at your desired rate.
Once setup for the applicator and preferences, and
configured for the rates/limits, the monitor is typically
used in the “RATE 1” or “RATE 2” FLOW CONTROL
modes.
Liq: Starting Application with Console
1.
Enter the tractor cab.
Refer to Figure 42
2.
At the console, set the POWER switch ON.
3. Set the MASTER switch to ON.
4. Set the BOOMS 1 or BOOMS 1,2&3 switch a on to
ON
all others don’t-care (suggest OFF).
5. Select the desired RATE preset.
6. Engage the remote for the hydraulic drive pump.
Advance lever to preset for +35% of desired rate.
7. Lower applicator to operating depth (if not already
lowered) and begin first pass.
See SCS 450 manual for monitor operation details.
Suspending Application
With the hydraulic drive pump option, material continues
to flow if the implement is raised while in motion. To
conserve material and prevent unintended application,
set the MASTER switch to OFF when raising.
When stopping, operating the MASTER switch is not
usually necessary, if the console has an active speed
sensor data source.
If suspending application for more than a minute, also set
the pump motor hydraulic circuit to Float.
No console actions are required to suspend application
with ground drive (preset or variable rate).
Liq: Stopping Application
1. Ground Drive: If possible, plan final passes so that
they occur prior to tank run-out. This keeps the pump
wet. If you do exhaust the material, refill with water.
2. At completion of application, apply almost all of the
remaining fertilizer on the last field. Refill the tank
with clean water.
3. Set application rate to maximum to shorten the
remaining steps:
Piston Pump Damage Risk:
When configuring the ground drive pump for high rates, check
the chart, slide chart or CDS-John Blue web calculator to
determine the maximum field speed that stays at or below the
pump’s maximum rated rpm.
4. Apply the water to the final field to flush system.
5. Close shut-off valves on both sides of all hose
connections.
Liq: Unhitch Liquid Nurse Tank
6.
Disconnect all tank-applicator couplers.
7. Disconnect the safety chains.
8. Remove the hitch pin. Move the trailer hitch off the
applicator’s draw bar.

a. The standard configuration uses only Valve 1. If optional section control is installed, also engage BOOMS switches 2 and 3.
• Ground Drive: Exchange the ground drive driving
sprocket to obtain High Range (page 94).
• Ground Drive: Set the pump dial to 10 (page 95).
• Hydraulic Drive: Set the console (Option) for
maximum rate.
