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.
This manual should remain with the attachment when sold.

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
SWITCH FUNCTIONS
Depth Control System On
Press and release touch-pad switch to energize
automatic DCS function.
LED lights when function is on.
Depth Control System Off
Press and release touch-pad switch to de-energize
automatic DCS function.
All LED’s are off.
Lower to Depth
Press and release touch-pad switch to lower
implement to pre-determined depth. LED flashes
until implement is lowered, then is steady.
Raise to Transport
Press and release touch-pad switch to raise
implement to transport position. LED flashes until
implement is fully raised, then is steady.
Manual Raise, Lower
Press and hold either end of large rocker switch to
raise or lower implement to desired height. When
switch is released, raising or lowering stops.
Note: Manual switch overrides and disengages
Automatic Mode. After using manual switch, press
and release Depth Control ON to return to automatic
mode.
Working Depth Selector
Turn rotary selector switch to set desired tillage
depth, with “A” as the shallowest setting and “N” the
deepest setting.
Note: Because of equipment variations, letters do
not indicate specific depths. Scale from “A” to “N” is
for relative positioning only.
IMPORTANT! Do not use this switch to routinely
raise and lower implement during field operation.
Hydraulic System Switch
-Press two-position rocker switch so red end
shows if tractor hydraulic system is open-center
or certain pressure-compensated types.
-Press switch so red end does not show if tractor
hydraulic system is closed-center type or other
pressure-compensated types.
Operating Notes:
a. For implement to operate with DCS, tractor
hydraulic remote lever must be in detent
position.
b. With DCS installed, tractor valve cannot be
used to raise and lower implement.

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.
5. Press and release “Raise to Transport”
switch.
The system is now calibrated. Recalibrate if the DCS
is moved to another implement, deactivated, or
disconnected from the power supply.
