INTRODUCTION
The Glencoe(r) Depth Control System DCS3000 gives fingertip single point depth control of towed
implements using state of the art agricultural electronics. The system allows quick and easy adjustment of
implement working depth from the operator’s seat. The automatic mode allows the system to return an
implement to an operator-selected working depth with the touch of a button. A manual mode of operation will
operate the tractor hydraulics when automatic mode is not used.
The DCS3000 repeats the working depth for the proper incorporation of lime, fertilizer, herbicides, and
pesticides. The DCS3000 also provides a means of insuring proper working depth for different tillage
operations, from primary, single pass through finishing and incorporation.
The DCS3000 can be installed on these Glencoe(r) tillage implements:
UM4650 SF4500 FC3500 CC4450 SS7400 DR8600
UM6000 SF4600 FC3550
FC3600
This manual contains information necessary for correct adjustment and safe operation of your implement
attachment. Read it carefully.

INTRODUCTION
HYDRAULIC SYSTEM PURGING
For proper machine performance, the hydraulic
system must be fully charged with fluid and purged
of air with or without the DCS.
The initial purging procedure is normally completed
at the dealership after the implement is set up. If the
DCS is added later, air enters the system when the
hydraulic lines are disconnected to install the control
valve. After the DCS installation is completed, purge
air as described later.
TRACTOR REQUIREMENTS
The tractor must have 12 VDC, negative ground,
available for the monitor.
No additional hydraulic circuits are required. After
installation, the DCS becomes an integral part of the
implement lift circuit.
The system may be used with open center, closed
center or pressure-flow compensated tractor
hydraulic systems.
SAFETY
•Always raise implement, shut off tractor engine
and install cylinder lockup brackets before
making adjustments.
•Be sure bystanders are clear before operating
tractor and machine.
•If operator does not understand any part of this
manual or machine operation, contact local
authorized Glencoe(r) dealer or AGCO Corp.
•Do not allow anyone to operate implement until
after reading this manual and understanding
safety and operation of this machine.
•Do not attempt to lubricate or adjust implement
while machine is in operation.
•Always shut off tractor engine, shift to park
position (or shift to neutral), set brakes, and
relieve tractor hydraulic pressure before
dismounting tractor or working around
machine.

OPERATION
BEFORE USE:
Before using the DCS, whether for the first time
when new, or for the season:
1. Connect hydraulic hoses correctly and be sure
rocker switch on bottom of monitor is positioned
correctly (next column).
2. Connect electrical system (next column).
3. Purge air from implement hydraulic lift system
(pp. 7, 25).
4. Calibrate DCS for implement (p. 5).
HYDRAULIC AND ELECTRICAL
CONNECTIONS
Hydraulic System Types
Note: See tractor dealer if unsure what type
hydraulic system is in tractor.
If the tractor has:
-An open-center hydraulic system, the optional
solenoid valve must be installed with the switch
red end showing (next page).
- A closed-center system, the valve is not
required and the switch must be positioned to
NOT show red.
- A pressure-compensated system, the valve
may or may not be required and the switch must
be positioned accordingly.
Due to differences between tractor brands and
models with pressure-compensated hydraulic
systems, no one switch position can be specified for
all. In general, if the switch is set for a close-center
system but engine speed drops by five rpm or more
when the automatic mode is turned on, the optional
valve is required.
IMPORTANT! Do not operate DCS with switch in
open-center mode (red showing) without valve
installed.
Hose Connections to Tractor
Connect the lift cylinder hoses to the tractor outlets
(Fig. 3) as follows:
- Hose from Port T-1 (side of valve block) to
pressure outlet.
- Hose from Port T-2 (front) to return outlet.
Note: If connected otherwise, implement will not lift
or lower in either automatic or manual mode.
Electrical
The control monitor can be connected directly to the
battery or to an in-cab auxiliary plug. Harnesses for
both connections are included in the DCS kit.
When connecting directly to the battery, connect:
- Black wire (-) to negative terminal.
- Red wire (+) to positive terminal.
Note: DCS will not work if wires are reversed.

OPERATION
OPERATING MODES
General
The depth control system has three operating
modes:
- Manual mode
- Automatic mode
- Error mode
Manual and automatic modes are selected by the
operator. The error mode cannot be selected, but
automatically appears when an apparent error
exists.
Note: Before operating, be sure startup procedures
on pp. 3, 5, 7 are completed.
Manual Mode
With tractor hydraulic lever in detent position:
1. Use “Manual Raise” switch position to raise
implement (previous page).
2. Use “Manual Lower” switch position to lower
implement.
Automatic Mode
Note: Calibrate depth control system if required.
1. Push tractor hydraulic lever to detent position.
2. Press and release “Depth Control System On”
switch.
3. Turn rotary switch to obtain desired depth.
4. Use “Raise to Transport” and “Lower to
Depth” switches to raise and lower implement.
Note: If manual switch is used, system reverts to
Manual Mode.
Note: If DCS is on when power is shut off, monitor
reverts to Manual Mode upon startup.
Error Mode
The error mode is automatically entered when an
apparent problem exists as identified by the monitor
program.
When in error mode, the LED’s flash individually or
in multiples at a rate of two per second. Four
flashing combinations exist:
-OnLED
- Raise or Lower LED’s
- On, Raise, or Lower LED’s
- On, Raise, and Lower LED’s
Refer to MONITOR TROUBLESHOOTING (next
page) for explanations and probable cause
information.
CALIBRATION
To achieve the full range of implement working
depth, calibrate the depth control system as follows:
1. If implement has turnbuckles for depth
control, adjust turnbuckles to obtain desired
depth.
2. With DCS off, completely retract lift cylinders
using “Manual Lower” switch.
3. Rotate “Working Depth” dial to “N” position.
4. Press and release “Depth Control System On”
switch.

MAINTENANCE
PURGING AIR FROM LIFT SYSTEM
IMPORTANT! Cylinder operation will be very erratic
and uneven until all air is purged from main lift
circuit.
Note: Also see pp. 25, 26.
1. With rod ends of lift cylinders disconnected, *
slowly extend cylinders. When fully extended,
hold tractor valve open for 30-60 seconds,
allowing air to purge from system.
2. Fully retract and extend cylinder(s) several
times (usually 3-4) to completely purge air from
circuit. Repeat Step #1 as required.
3. Fully extend cylinders and hold valve open for
at least two minutes with maximum flow (tractor
at high idle).
4. When cylinder(s) extend evenly and smoothly,
reconnect cylinders to wheel arms.*
5. Slowly raise and lower machine. If cylinders
continue to operate in unison and implement
remains level, circuit is charged with fluid and air
is purged.
6. Check for and correct leaks if required.
7. Add hydraulic fluid to tractor as required.
* Optional. If the implement has been properly set up
and operated, it is not necessary to disconnect the
cylinders.
PURGING AIR DURING OPERATION
In manual mode, fully raise the implement while
turning at the end of the field to purge air which may
be trapped in the system
WARNING! RECHECK FLUID LEVEL IN
TRACTOR RESERVOIR AFTER
CHARGING AND PURGING AIR
FROM HYDRAULIC SYSTEM.
FAILURE TO DO SO CAN RESULT IN
PERSONAL INJURY AND/OR
DAMAGE TO TRACTOR OR
IMPLEMENT. ADD FLUID AS
REQUIRED.
WARNING! TO PREVENT POSSIBLE SERIOUS
INJURY OR DEATH, CLEAR
BYSTANDERS FROM AREA WHEN
RAISING AND LOWERING
IMPLEMENT AND/OR WINGS.
ELECTRIC CURRENT DRAW
Standard Valve Block
A small amount of current is continuously drawn by
the monitor, whether or not it is in active use.
Therefore, when not using the DCS for longer than
overnight, disconnect from the tractor power source
to prevent a discharged tractor battery.
Valve Block with Open Center Solenoid
When the Hydraulic System rocker switch is
energized (red part of switch shoeing), current is
drawn at a much greater rate than the monitor alone.
Notes:
a. Disconnect harness at monitor if connected
directly to battery.
b. Disconnect at tractor outlet if tractor outlet
harness is used.
IMPORTANT! When not using depth control system
for long periods, turn switch off and disconnect
control monitor.
FUSE PROTECTION
The monitor-to-battery harness is equipped with a 15
amp automotive blade-type fuse. If the fuse fails,
troubleshoot and repair the system, then replace
with one of same size and type.
If the plug-in harness is used, the tractor electrical
system provides fuse protection.

MAINTENANCE
CARE AND MAINTENANCE
•Always keep the monitor dry. In most cases, the
tractor cab provides sufficient protection.
IMPORTANT! Monitor is not watertight and must
be protected from moisture.
•Remove monitor from tractor without cab and
store inside overnight.
•Store monitor off-season in a cool, dry place.
•If monitor must be opened to replace a rocker
switch, wear a wristband grounding strap to the
circuit board for static electricity.
•Due to delicate and sophisticated electronic
circuitry, Glencoe® does not recommend or
authorize repair of internal circuit board.
•When working on tractor electrical system,
disconnect monitor input wiring harness.
•Disconnect both wiring harnesses and remove
monitor from tractor when arc welding on
tractor or implement.
•Keep dirt and water out of hydraulic system.
