However, the opposite side feeder can be set to run by pressing the Feed Switch but it will not
deliver the ration displayed since it is working in stand-by mode, running just so long as the
FeedSwitchis heldover.
Setting the Ration Display to zero and pressing the Feed Switch will deliver cake continuously
foras longas theswitchisheldover.Thisis a convenient stand-by feature.
SoftwareVersions
TheDigitalFeederControl issuppliedwith oneof twoversionsof software:
V2.05 - Standard Version- Once the feed switch is operated andthe counter has counted down
to zero (0), the ration display stays at zero (0) and a new ration has to be dialled up to feed
again.
V2.06 - Return To Ration Version (Rotary Parlour) - Once the feed switch is operated and the
counter has counted down to zero (0), the ration display returns to the previous ration value
readyto feedagain.NB -Therationcan bealteredbyturningthe rationselectorknob.
DIGITAL CONTROL
INSTALLATION
& OPERATION: 1
The Digital Feeder Control from ATL Agricultural Technology offers a most elegant and yet
simplewayof feedingin parlour.
It is connected to either a single feeder, an ATL Abreast Feeder with automatic feed flaps or two
feedersoneoneach sideof theparlour.Settingupthe installation todeliveraconsistentportion
of feed from any feeder is quick and easy by virtue of the Global Timing Pulse, a unique
innovation inparlourfeeding.
Feeding is fast- really fast. Just dial the number of portions required for a cow, press the FEED
switch and it's done. The feeder will deliver the cake completely unattended. No fiddly buttons
to press or complex codes to remember. The ATL Digital Feeder Control gives the farmer
completecontrol.
OperatingtheControl
The feeding procedure for the Digital Feeder Control is simple. Turning the Ration Selector knob
increases or decreases the ration which is displayed in the window. For controls set up to drive a
single feeder such as the ATL Abreast unit with a manual flap, pressing the Feed Switchin either
direction will start the feeder, both Indicators illuminate and the display counts down as the
feedis dispenseduntilitreaches zeroand thefeedermotor turnsoff.
Controls which drive two feeders, pressing the feed switch to the left starts the feeder on the left
and pressing it to the right starts the feeder on the right. The appropriate Motor Running
Indicator illuminates to show which ‘side’ is running and again, when the display reaches zero
thefeederis turnedoff.
ATL Abreast Feeders with an Automatic flap have a single feeder motor which operates
regardless of whether the Feed Switch is pressed left or right, but the Auto flap is moved in the
directionofthe FeedSwitchto divertthe caketo thatmanger.Pressand holdtheFeedSwitchfor
afew secondsto allowtheAutoflap tomove andsettle.
The Ration Selector is a rotary switch; it has no end stops and can be rotated through 360
degrees in either direction. As it is turned, the display increments or decrements, depending
upon direction. The display number represents the multiple of portions (to a maximum of 99)
set up using the Timing Pulse. So, for example if the installation was calibrated to deliver
500gms (about 1pound), a figure of '7' in the display window represents 7 x 500gms or
3.5kilograms.
If the Motor Running Indicator(s) fail to illuminate when the Feed Switch is pressed and the
Ration Display begins to flash, there is a fault with the feeder and the thermal trip inside the
Control has interrupted the feeder power supply. This generally means the feeder motor is
drawing too much current- it may be jammed, badly worn or has short-circuit windings.
Release the switch, turn the Ration Selector until the display reads 'zero, allow the thermal trip
tocool fora minuteor soand tryagain.Ifthe faultpersistscheckand servicethefeeder motor.
Even when the feeder is running it is possible to increase or decrease the ration simply by
turningtheRationSelector. TheDigitalFeederControlwilldeliverthenewration.
If a feeder is already running, pressing the Feed Switch again for that side will have no effect.

Installation
Power Supplies or Interfaces must be provided with a clean 230volt mains supply. Avoid
sharinganoutlet withanotherload.Use a switched,fusedoutletnota13Ampplugandsocket.
Position the Digital Feeder Controls as high as possible away from moisture and splashes
butwithineasy, convenient reach.Cableruns shouldbeas shortas possible.
The DC supply to the Controls and the Timing Pulse cable may occupy the same conduit,
but must be kept separate from the Feeder DC, Milk Pump and Vacuum Pulsation Unit supplies.
Cables should be at least 500mm from mains cabling and as far away from fluorescent lights as
possible;theycaninterfere withtheTimingPulse.
Always use the cable entries along the bottom edge of the Control casing. Although some
of the diagrams show entry to the side or top of the case, this is for clarity only and must be
avoided.
Do not position the Controls along a straight run of conduit- use 'T' connectors. Straight
runscreateunimpededair pathsandmoisture canbe depositedinsidetheControls.

2.5mmcsa forDCpowersuppliesto DigitalFeederControl.
1.5mmcsa forDigital Controlto FeederMotors.
0.5mmcsa forTimingPulsesupplyfrompowersupplyto Control.
A single run of 2.5mm csacable from the power supply will provide sufficient power for up to 6
Controls. Additional Controls will require a further cable run back to the power supply. Two
outlets are provided for both (+) and (-) cables on ATL power supplies. Arrange the cable
neatlyinsidethe Controlcasing.Neverlooporcoilsparecable-cutitto thecorrectlength.
If new Controls are replacing the older mechanical type, check the existing connections
cutting away any 'blackened' cable before fitting the cables. The connector configurations are
differentbetween oldmechanicaland newdigitaltypes (DataSheet8A).
Diodes must be fitted across low voltage (12 or 24volt) DC feeder motors or solenoid
terminals. ATL feeders already have these fitted as standard; most other makes do not.
Running a motor without a diode fitted will expose the Control circuitry to back emf, could cause
irreparable damage and will certainly void the warranty. Do not fit diodes to high voltage - 110
or230voltmotors orany motoroperatingwithan ACsupply.
Check for splits or holes to switch covers and the display membrane. If there is any
opportunity for water to enter the casing do not use the Control. Doing so could jeopardise the
warranty.Replace thedamagedpartassoonaspossible.

M
+ -
The positive endof the diode is marked
with a band; connect to the (+) terminal.
Preferred arrangement with a resistor in
series with the diode
Resistor:100 Ohms (100R) 2watt
Diode: 1N4002100v PIV 1Amp or better
Do NOT fit diodes to AC motors.
The Control can operate both electric and vacuum feeders; 12 volt DC electric motor feeders are
supplied directly from the control whereas vacuum feeders are operated via a solenoid valve.
Higher voltage feeders can be accommodated but require a Feeder Interface to switch the high
voltage-ACor DC-tothefeedermotors.
Before the system is switched on for the first time, the output configuration must be
checked. The Configuration Jumper is located on the rear of the Control circuit board, bottom
right-hand corner(seepage 3).
VacuumOperatedFeeders:
Vacuum feeders will need the Jumper to be fitted in one of the three positions shown in Figures
(2 to 4) on the following page. The actual position- 1, 2 or 4 pulse depends upon the feeder
type.As ageneralguide,themajormakes shouldbesetas follows:

FeederCalibrationSlides.
ATL and some other manufacturers, fit a slide to the feeder outlet which can be positioned to
restrict the delivery of feed to the chute- a simple form of calibration. Make sure that calibration
using the slides has been carried out in accordance with the feeder installation manual before
settingtheTimingPulse.
SpecialFeederConnections.
The Digital Feeder Control switches the positive (+) 12 volt DC supply which means that those
feeders that normally use a switched negative supply must have their connections reversed
making sure that any fitted diodes are also changed to the correct polarity - the banded end
indicatesthepositive(+) connection.

FINE Timing Pulse adjust:
Range: 1 to 3 seconds
Location of Timing Pulse Controls in the ATL Power Supplies.
The two lower controls do not appear on Interface units which are used in conjunction with other
makes of power supply.
TheGlobalTimingPulse.
A powerfulfeature of the Digital Feeder Control system is theGlobal Timing Pulse. A single cable
links all of the Controls to a common timing pulse to ensure that all are running to the same
clock period. The great advantageof this arrangement is that just one feeder need be set up and
calibrated; all of the others- provided they arein good working condition - will then deliver the
samefeedportion.
The Timing Pulse Controls are situated inside the Power Supply or Interface and consist of
two, small rotary controls, one provides a coarse time adjustment and the other a fine
adjustment. ATLpower supplies havefour controlsgroupedtogether;onlythe twomarked inthe
figureshouldbe adjusted.
# Set both the coarse andfine timing pulse controls to themid-point.
# Turn the power on and rotate the Ration Selector on a single Control until the digit '4' is
displayed in thewindow.
# Push the FEED switcheither right or left. The associated feeder motor should start and feed will
be delivered.
# Weigh the quantity of feed delivered; ifit is less than 2kg, turn the Coarse Timing control
clockwise. For a delivery larger than 2kg turn the Coarse control anti-clockwise. Push the
FEED switchfor another delivery and repeat the process.
# Get as close as possible to the desired portion of feed using the Coarse control and then 'fine-
tune' the amountusing the Fine control.
Thissimpleprocesscan berepeated atany timewhen thefeed formulationordensitychanges.

Digital Control 24volt AC Interface for Existing Power Supplies
The ATL 24volt AC Power Supply Interface converts the
24volt AC output from an existing power supply and
rectifies it to drive the feeders or solenoid valves.
Additionally, a 230volt AC mains input provides the
12volt DC necessary for the Digital Controls and Global
The AC interface may also be used with existing power
supplies sourcing 24volts DC. and should be connected in
precisely the same way. However, the rectifier inside the
interface will reduce the voltage levels slightly which may
affect the feeder motors- they will tend to run slower.
A 230volt AC supply is required for the interface. The
