Hydraulic Drive Operations
The centrifugal pump
is driven by an integrated
hydraulic motor. The output of the pump is under
pressure whenever the hydraulic motor circuit is
activated. Rate is regulated by a flow control valve
,
and monitored by a flow meter
, both connected to a
Raven SCS 450 console (or other compatible Raven
console).
Hydraulic Drive Start-Up
Prior to first use, determine the hydraulic remote circuit
flow rate setting per the procedure on page 94.
12. Set console MASTER switch OFF.
13. Set console POWER switch ON.
14. Select FLOW CONTROL RATE1 or RATE2 as
desired, and verify rate setting.
15. Set console BOOMS
a
switch 1 ON.
16. Set the flow rate for the hydraulic remote circuit as
established by the procedure on page 94.
17. Activate the circuit by moving the lever to Retract.
You may hear the pump operating, but with the
MASTER switch off, no material flows to rows.
18. Set the MASTER switch ON. Check for material flow
at the tines. Prime second hydraulic pump as
required.
19. Begin field operations. Monitor the fertilizer pressure
gauge (or PSI display on optional console).
Hydraulic Drive Field Operations
20. Monitor the fertilizer manifold pressure (gauge or PSI
display on optional console).
21. Mind the fertilizer tank levels while planting, both to:
a. confirm expected consumption rate, and;
b. avoid running the pump dry.
22. If residual fertilizer is not recovered at end of
planting, apply it to the last field planted.
23. Clean out fertilizer system per page 103.
Hydraulic Drive Pauses and Turns
With the optional hydraulic drive system, pauses cause
the speed sensor to report zero speed, which causes the
console to close the flow control valve. Set the pump
hydraulic remote to Float if stopping for and extended
period.
When the applicator is stopped, or lifted, the pump stops.
The boom is still pressurized, but this bleeds down to
8 psi very quickly (seconds), at which point the nozzle
clamp check valves close off flow to the rows.
For turns and field moves, set the MASTER switch OFF
to avoid material loss. If the factory configuration of the
plumbing has been modified for section control, use the
BOOM switches as desired for point row applications.
a. The standard configuration uses only Valve 1. If optional section control is installed, also engage BOOMS switches 2 and 3.
Agricultural Chemical Hazard:
Avoid contact with skin or eyes. Wear proper protective
equipment as required by chemical manufacturer. Avoid
prolonged breathing of chemical fumes. Wear respirator as
required by chemical manufacturer. Some chemicals will cause
serious burns, lung damage, and death. Seek medical
assistance immediately if accident occurs. Know what to do in
case of accident.
Equipment Damage/Material Misapplication Risks:
Do not run pump dry. With all drive chains in place, the pump
always runs when the fertilizer applicator is lowered and in
motion. Air rapidly damages a pump. Keep fluid in pump at all
times. Disconnect a chain when not applying fertilizer.
If fertilizer is exhausted prematurely, reload fertilizer
immediately. If fertilizer is not available, load clean water,
continue planting with pump operating (to flush system), and
disconnect pump drive before water is exhausted (to keep
pump wet).
Sharp Object Hazard:
Exercise caution when near and handling the ground drive
wheel. Wear gloves. The tines may be sharp.
