mPOWER REQUIREMENT:
There are three possibilities for supplying power to the AGS 900 gate operator. The standard
power supply version is made to connect directly to 115 Volt, 5 Amp power source and is available for
standard capability and full systems capability models. This power supply must be at or near the gate
operator location. Because of the low current draw, 115 Volt power may be run as far as 1000 feet
with 12 gauge wire from the main breaker panel and can be run much farther with larger wire.
Another possibility for supplying power to the operator is with the low voltage battery back-up version
of the AGS 900. To supply power to the AGS 900 battery back-up, wire as small as 16 gauge can be
run as far as 300 feet from a charger that is plugged in remotely. Because the power is low 12 Volt
DC, the wire can be direct burial wire which eliminates the need for expensive conduit runs. The other
possibility for supplying power to the AGS 900 is with the Solar power version of the operator. The
Solar model does not require any power to be run because the operator and solar power supply are
self contained. The panel may be placed several hundred feet from the operator if this is necessary
to achieve maximum sunlight conditions.

mMOUNTING:
There are two ways to mount the AGS 900 operator. One way to mount the operator is to
attach it with bolts to a concrete surface using the optional concrete mounting stand and sleeve
anchors. In some cases there will already be an existing concrete surface or pad available to bolt the
operator to. If there is no existing concrete surface or pad, it is very easy to fashion one so that the
operator can be bolted down at a later time using sleeve anchors. The other way to mount the AGS
900 operator is directly into the earth with the two 2" X 30" mounting posts that have been provided.
For this installation the posts are attached to the operator, one post hole is made in the earth and
then the operator with posts attached is set in place. The cement can then be poured into the post
hole and will dry within minutes if concrete accelerator is used. The operator can be put into full
operation the very same day.

Features
STANDARD AND FULL SYSTEMS CAPABILITY
mm
mm
mSENSITIVITY
As with other AGS gate openers, the AGS 900 has a built-in safety feature which when adjusted properly will
deliver only enough power to the motor to overcome the resistance of the gate. What this means is that if the gate runs into
a vehicle or pedestrian, the gate will immediately stop or reverse. This "gate sensitivity" feature is unique from others
because it functions while the gate is both opening and closing. Because of the DC motor technology incorporated into the
AGS 900, the sensitivity feature is much more sensitive and is at least 50% more effective than traditional AC current
sensors.
mm
mm
mSOFT START/SOFT STOP
A unique feature of the AGS 900 is the Soft Start/Soft Stop feature. Traditional gate openers will begin opening the
gate with full power causing a yanking or jerking effect that severely decreases the life of mechanical parts. The AGS 900
will begin opening or closing the gate very slowly and will gradually increase to full speed. This creates a very gentle gate
translation which considerably reduces the amount of wear and tear on all mechanical parts.
mm
mm
mMANUAL RELEASE KEY SWITCH
This simple on-off key switch is built into the side of the operator. In an emergency, even with the power off, the
gate can be pushed open manually after turning the key counter-clockwise.
mm
mm
mELECTRONIC BRAKE
Traditional gate openers typically have a mechanical brake or clutch which requires special maintenance. The DC
motor technology that is incorporated into the AGS 900 provides the gate opener with a brake that will never wear out. This
patented feature causes the gate to come to a stop and keeps the gate locked when stopped in any position.
mm
mm
mBATTERY BACK-UP/LOW VOLTAGE
The AGS 900 is available in both battery back-up and solar versions. The main and most obvious benefit to having
battery back-up or solar is the ability to open and close the gate even when there is no power. This in itself provides an
extremely high level of convenience. If there is a power failure the gate will operate as it normally does and can be opened
up to 150 times before power is restored. Another very important benefit to having battery back-up is that it is not
necessary to have 115 Volts at the operator location because running high voltage is typically very expensive and highly
regulated. All that is needed to supply power to a battery back-up version of the AGS 900 is some inexpensive low voltage
burial cable. If the cable is 16 gauge it can be run as far as 300 feet. For solar versions of the AGS 900, no power needs to
be run to the operator. The solar version has a solar panel which is normally attached to the gate opener but can placed
anywhere that allows the panel to receive maximum sunlight.
mm
mm
mSTANDARD CAPABILITY INPUT FUNCTIONS
The standard capability circuit board has two input functions, open and stop. Both inputs require normally open
contacts. The open input function is used to both open and close the gate and the stop input function is used to interrupt
the gate while it is running and bring it to a stop. Stop input can also be used as a simple safety input to stop the gate
before contacting a vehicle or pedestrian.
FULL SYSTEMS CAPABILITY ONLY
mm
mm
mVISUAL FEEDBACK
The AGS 900 Full Systems Capability circuit board has been equipped with visual feedback LED's (small indicator
lights) to help simplify installation and troubleshooting. There are LED's located directly beside each input terminal to
indicate if any input devices are active. There are also two LED's which indicate that the circuit board is delivering power to
the motor and are labeled O and C for either the Opening or Closing directions of travel respectively. Collectively, all of the
LED's combined provide quick glance information to the installer or service technician showing visually what is happening
in the normally invisible operation of the circuit board.

mm
mm
mAUTO CLOSE TIMER
The operator comes factory preset with the auto close timer function OFF. The auto close timer will close the gate
automatically after a specific amount of time has elapsed. The amount of time can be easily adjusted between 0 and 45
seconds by turning a small "pot" located on the edge of the circuit board (See page 17). The timer can be disabled or
activated by flipping a single switch located on the top edge of the circuit board. If the timer will be used it is recommended
that some type of supplementary safety device (loops, photo beam etc.) be installed.
mm
mm
mGATE SENSITIVITY ADJUSTMENT
The amount of force necessary to stop the gate can be adjusted to conform to the various sizes and weights of
any particular gate. The full systems capability circuit board provides separate adjustments for both the opening and
closing direction. When adjusting the sensitivity, the operator can be given only as much energy as is necessary to
overcome the resistance of the gate. If the gate should strike an obstruction in the closing direction, the gate will reverse to
the open position. If the gate should strike an obstruction in the opening direction, the gate will stop and remain stopped
until commanded to return to operation. (See page 17)
mm
mm
mMASTER AND SLAVE
Some very large entrances may require the use of two gates. If this is the case, the two gates can be easily
automated using the "master and slave" configuration. This configuration uses two gates and two operators in ONE
driveway. Although models equipped with standard capability can be connected as master and slave, they may not always
give satisfactory performance and may not work simultaneously. Full systems capability models have terminals provided
especially for master and slave applications and will reliably operate simultaneously all of the time.
mm
mm
mPULSE OPEN INPUT
The Pulse Open input feature is an open input on the circuit board which will increase the security of the AGS 900
gate operator system. When an open input device such as a radio receiver is connected to the Pulse Open input, and the
radio transmitter is pressed, the gate operator will activate but will then ignore the input if the input is prolonged. What is
significant about this feature is that there is the possibility of a transmitter button being stuck and if the radio receiver is
connected to the standard open input the gate will be held open. If the radio receiver is connected to the Pulse Open input
on terminals 6 and 7, the circuit board will ignore the stuck input and will allow the gate to close. The pulse open input is
designed for but not limited to a radio receiver. For added security any open input device may be used with Pulse Open
including push buttons, key switches, numerical key pads etc.
mm
mm
mPERIPHERALS
POWER SUPPLY: There is 12 Volts DC .1 AMP available on the circuit board which is used to supply power to a radio
receiver or other device.
OPEN INPUT: Normally open devices are connected to terminals 5 and 6 on the circuit board to cause the gate to open
and/or close in PUSH-TO-OPEN/PUSH-TO-CLOSE (Timer switch OFF) mode of operation. Normally open devices are connected to
terminals 5 and 6 to cause the gate to open in AUTO CLOSE TIMER (Timer switch ON) mode of operation. In this mode of operation
the AUTO CLOSE TIMER will automatically close the gate after a specific amount of time has elapsed. The Auto Close Timer is
adjustable between 0-45 seconds. These normally open devices can be push buttons, radio receivers, key switches, loop detectors,
photo electric beams, 24 hour timers, etc. See FEATURES on the next page for other open input capabilities.
PULSE OPEN INPUT: Normally open devices are connected to terminals 6 and 7 on the circuit board to cause the gate to
open. Pulse Open Input functions identical to Open Input with the exception that it will not hold open the gate. If a transmitter or other
open device is stuck on, the gate will still close. This feature is sometimes used to provide a higher level of security but should be used
only in addition to another open device connected to Open Input so the gate can still be opened if necessary.
SAFETY INPUT: Normally open devices are connected to terminals 4 and 6 on the AGS 900 circuit board to cause the gate
operator to open and/or hold the gate open in any position except the fully closed position. Normally open safety input devices that can
be used are push buttons, radio receivers, key switches, loop detectors, photo electric beams, 24 hour timers, etc.
N.C. STOP INPUT: Normally closed devices are connected to terminals 8 and 9 on the circuit board after removing the stop
jumper that is on terminals 8 and 9. The N.C. Stop Input will cause the gate to stop at any position and will remain stopped until
activated to open or close.
N.O. STOP INPUT: Normally open devices are connected to terminals 9 and 11 to cause the gate to stop in any position
until the gate is again activated to open or close. N.O. Stop Input functions identical to N.C. Stop input with the exception that it
requires normally open contacts instead of normally closed contacts.
CLOSE INPUT: Normally open devices are connected to terminals 9 and 10 on the circuit board to cause the gate operator
to close the gate when in any position. Normally open input devices that can be used are push buttons, radio receivers, key switches,
loop detectors, photo electric beams, 24 hour timers, etc.

Installation
mThe tail end of the gate should
extend approximately 18 inches beyond
the edge of the driveway. If this is not the
case, an extension tail will need to be
added to the gate. This will give room for
the gate operator. Make the extension
tail 18" X 18" as shown. If the gate has
not yet been fabricated, add 18" to the
length of the gate.
mRemove the gate operator from
it's package and make sure that all parts
are included. Refer to General Informa-
tion and Parts Identification.
mIf the gate operator will be post
mounted, insert the two supplied mount-
ing posts into the bottom of the gate
operator and through the u-bolts. The
posts should insert 5 inches into the
operator. Firmly tighten the u-bolt nuts to
securely fasten the posts.
mRefer to figure 3 to determine
the operator location and dig a post hole
approximately 25 inches deep or more.
Set the operator with posts attached into
the post hole and fill the hole with
cement. While the concrete is setting,
re-check the position of the gate opera-
tor so that it is positioned as in figure 3
at left.

pg 10
Installation Continued...
mIf it is preferable to mount the
gate operator onto a cement pad, form a
cement pad that is 14" by 16" as shown
in figure 4 at left. For this installation, an
optional concrete mounting stand is
required. The cement pad should be at
least 6" deep and may protrude above
the ground 4" or more as shown if it is
desirable to elevate the gate operator.
Elevating the gate operator may prevent
unnecessary flood damage in places
where the drainage is not adequate.
mPlace the operator on the
optional concrete mounting stand by
inserting the vertical pipes up through
the bottom of the gate operator and
through the u-bolts. Tighten the u-bolt
nuts firmly to secure the concrete
mounting stand to the gate operator.
mPlace the operator with stand
onto the cement pad and position it as
shown in figure 5 at left. Drill through the
four corner holes of the stand and into
the cement pad using a 3/8" masonry bit.
The holes should be at least 3-1/2"
deep. Drive 3/8" sleeve anchors into the
holes and tighten firmly.
mThe chain may be threaded
through the sprockets in one of two ways
as shown at left and the choice is simply
a matter of preference. Threading the
chain one way will make the chain low
as it extends across the driveway and
the other way will make it higher. The
side plates may be moved up or down by
loosening the nuts which secure them,
moving the plate to it's alternate position,
then re-tightening the nuts.
mThe ends of the chain are

attached to each end of the gate by
using the gate brackets and chain
bolts as shown at left. If the gate frame
is 2" X 2" square tube, the gate
brackets may bolted to the gate using
the square u-bolts as shown. For
round tubular frames, use the supplied
round u-bolts for attaching the brack-
ets. In this case use the self tapping
screw which prevents the bracket from
shifting. For irregular sized gate
frames, the gate brackets should be
welded to the gate. Attach the chain
ends with master links and tension the
chain by tightening the chain bolt nuts.
mThe limits of travel determine
where the gate stops in both the open
and closed positions. These limits may
be adjusted very closely without any
power to the gate operator. Before
making these adjustments, the gate
operator may be put into manual
release by turning the manual release
key switch as shown at left. This
allows the gate to be pushed manually
in either direction. Be careful not to run
the limit nuts past the limit switches as
this may cause damage to the
switches.
mThe limits of travel are ad-
justed by positioning the limit nuts
against the limit switches (pressing in
the switch) while the gate is open or
closed. To adjust the limit nuts, first
push down on the limit nut guide plate.
This allows the limit nuts to be freely
spun up or down the screw. One limit
nut should press in one limit switch
when the gate is open, and the other
nut should press in the other switch
when the gate is closed. When
finished, be sure that the limit guide
plate firmly engages both limit nuts.
DO NOT ADJUST THE
LIMITS WHILE
THE POWER IS ON

pg 12
Electrical
mBefore making any electrical
connections be sure that the power is
switched off. If the gate operator is a
standard 115 Volt model, run conduit
from the 115 Volt power source into the
gate operator. The gate operator is
provided with a 90 degree flexible
conduit fitting for installations where the
electrical box is relatively close. Because
of the 90 degree fitting, it is generally
easier to run the electrical wires through
the flexible conduit before attaching the
conduit. Wiring for other devices such as
push buttons may also be run at this
time either in the same conduit or in
another.
mIf not already done, run three 12
gauge wires (hot, neutral, and ground)
from the power source, through the
conduit and into the gate operator. It is
easiest to run these wires back out of
the large hole in the operator along with
the three existing wires. This allows the
connections to be made externally and
then later inserted back into the operator
through the large hole. Be sure to use
wire nuts to secure these connections.
Make the connections as follows:
Black to (hot)
White to (neutral)
Green to (ground)
mIf the gate operator is a battery
back-up model, it is packaged from the
factory with the battery disconnected.
Connect the red wire to the positive
battery terminal and the black wire to the
negative battery terminal. There are
wires provided for connecting the low
voltage burial cable from the float
charger to the gate operator. The burial
cable may be run through the knock-out
in the bottom of the battery enclosure
and then connected to the two wires
provided. Be sure that the positive and
negative match the positive and negative
of the charger.

pg 13
Electrical continued...
mConnect the other end of the
burial cable from the operator to the float
charger. Be sure to match the positive
and negative terminals of the charger to
the positive and negative terminals of
the battery. Once the connections are
made, plug the charger into a 115 Volt
outlet. If possible, it is desirable to locate
the charger out of the weather. Let the
charger charge the battery for a couple
of hours before putting into operation.
mIf the gate operator is solar
powered, no power will need to be run
into the machine. The solar panel is set
up to be attached to the gate operator
and extension pipes are provided to
elevate the panel up above the operator.
While assembling the pipes and attach-
ing the panel, run the wires from the
panel through the pipes. The ends of the
wires are provided with connectors
which can simply be plugged in. Turn the
panel so that it will get maximum sun-
light during the day. If necessary the
panel may be mounted away from the
gate operator to get it out of the shade
and into more consistent sunlight.
mSimilarly to the battery back-up,
the solar operator comes with the battery
wires disconnected. For both batteries,
connect the black wires to the negative
terminals and the red wires to the
positive terminals. The wires have been
labeled to make these connections
easier to do.

pg 14
Electrical continued...
mOPEN INPUT: Any device that is used to open the
gate from a closed position is an open input device. The
device used must provide normally open contacts. These
normally open contacts are connected to terminals 4 and 5.
These open input terminals will cause the gate operator to
open and/or close.
mSTOP INPUT: Any device that is used to stop the
gate operator while it is running in the open or closed direc-
tions is a stop input device. These stop input devices must
provide normally open contacts. To connect these normally
open contacts, use terminals 7 and 8. Stop input may also be
used for simple external safety devices which can be used to
stop the gate when there is a vehicle or a pedestrian present.
When the gate operator is told to stop using the stop input, the
gate will remain stopped until it is told again to run using the
open input.

mOPEN INPUT: Any device that is used to open the
gate from a closed position is an open input device. The
device used must provide normally open contacts. These
normally open contacts are connected to terminals 5 and 6.
These open input terminals will cause the gate operator to
open and/or close if the timer switch is in the OFF position. If
the timer switch is in the ON position, these open input
terminals will cause the gate operator to open and will hold the
gate open until the input is released and the hold open time
has elapsed.
mCLOSE INPUT: Any device that is used to close the
gate is a close input device. The device used must provide
normally open contacts. These normally open contacts are
connected to terminals 9 and 10. These close input terminals
will cause the gate operator to close the gate any time the
gate is in a non-closed position and can be used to override
the timer and close the gate prematurely.
mN.C. STOP INPUT: Any device that is used to stop
the gate operator while it is running in the open or closed
directions is a stop input device. These stop input devices
must provide normally closed contacts. To connect these
normally closed contacts, remove the stop jumper from
terminals 8 and 9 and then connect the contacts to these
same terminals 8 and 9.
mN.O. STOP INPUT: This input functions identical to
N.C. Stop with the exception that it requires normally open
contacts. These contacts are connected to terminals 9 and 11.
mSAFETY INPUT: Any device that is used to open and/
or hold open the gate while the gate is in a non-closed
position is a safety input device. The safety input device
must provide normally open contacts. These contacts are
connected to terminals 4 and 6. This function is especially
useful when the auto close timer is being used in prevent-
ing the gate from accidentally closing on a pedestrian or
vehicle.
mPULSE OPEN INPUT: The pulse open input
terminals were put on the circuit board as an alternative
connection for the radio receiver. This input functions
similarly to the standard open input with the exception that
it will not hold the gate open if the input remains present.
This feature will add additional security to the gate operator
system in the event that there is a transmitter that is stuck
on. Pulse open is found at terminals 6 and 7.

adjustment "pot" clockwise for less
sensitivity or counter clockwise for more
sensitivity. Try applying force against the
gate while it is moving both open and
close to test the setting (Caution: Do not
stand directly in the path of the gate
while doing this). The gate should stop
easily if the adjustment has been set
correctly and will remain stopped until a
push button is pressed again. Caution:
Disconnect power while making any
adjustments.
mThis step is for sensitivity
adjustments on the full systems capabil-
ity control board. To make adjustments,
use a small screw driver to turn the
adjustment "pots" clockwise for more
sensitivity or counter clockwise for less
sensitivity. There are separate adjust-
ments for both the opening and closing
directions of travel and these must both
be adjusted. Try applying force against
the gate while it is moving both open and
close to test the setting (Caution: Do not
stand directly in the path of the gate
while doing this). The gate should stop
or reverse easily. Caution: Disconnect
power while making any adjustments.
mIf the gate operator has the full
systems capability control board there is
the option of using the auto close timer
which will close the gate automatically
after it has opened. To turn this feature
on, flip the auto close timer to the on
position. To adjust the amount of time it
takes for the gate to begin closing use a
small screw driver to turn the adjustment
"pot" clockwise for more time (45 sec
max) or counter clockwise for less time.
It is recommended that if the auto close
timer function is used, that there be
additional safety equipment installed to
prevent the gate from closing into a
vehicle or pedestrian. Caution: Discon-
nect power while making adjustments.

mIf the gate seems to be functioning
in reverse, the right/left side operation
switch may need to be flipped (full system
capability only). One way to know if the
operator is working in reverse is to try the
sensitivity. If pressure is applied to the
gate while it is closing, it should reverse
and go open. If pressure is applied to the
gate while it is opening, it should stop and
remain stopped until activated again. If the
gate operator responds differently than
this, flip the right/left side operation switch.
If the auto close timer function is turned
on, this provides another way of knowing if
the operator is working in reverse. If when
the gate gets closed, the operator auto-
matically opens, the right/left side switch
may need to be flipped the other way.
mThe receivers and transmitters
normally come from the factory with a
preset switch setting that is the same in all
units. It is recommended that this setting
be changed to reduce the possibility of
unauthorized access through the gate. To
change the switch setting, simply set the
switches in the radio receiver to any
arbitrary setting and then set the switches
in the transmitter/s to match the switches
in the receiver. When changing switches,
do not use a pen or pencil because these
may cause debris to fall into the switches.
Use a paper clip or other device that will
not deposit debris. The battery in the
transmitter may last 1 to 2 years. Be sure
to replace the battery only with one that is
the same type as the original.

NOTE:
If the gates stop before they get to the
fully open or fully closed position, move
the violet wire from terminal 3 to terminal
1 on the master and move this same wire
from terminal 1 to terminal 3 on the slave.
NOTE:
1) The timer switch on the slave
circuit board must be OFF at
all times.
2) All peripheral devices must
be connected to the master
circuit board inputs.
