PRE-INSTALLATION NOTES  
The Allstar Gate Star 4000 (GS4000) Vehicular Gate Operator will  
provide convenience and assurance to the ultimate users for many  
years. It is ruggedly built of the finest materials and has been  
thoroughly inspected and tested at the Allstar factory. It has many  
features that will aid in the installation and testing of the complete gate  
system. The GS4000 is certified to comply with UL Standard for  
Safety 325, as revised March 1, 2000. (115 Volt version only.)  
The GS4000 is also provided with a Torque Limiter that may be  
adjusted to "slip" when an obstruction is encountered. However, the  
purpose of the Torque Limiter is to protect the GS4000 mechanical  
parts. Whether the overload is activated before the Torque Limiter slips  
will depend upon the "tightness" of the adjustment of the Torque  
Limiter. This adjustment will be explained in the final check out of the  
GS4000.  
Connections for External Entrapment Prevention Sensors  
NOTICE - BEFORE ATTEMPTING INSTALLATION,  
READ THIS MANUAL CAREFULLY SO YOU WILL  
BE THOROUGHLY FAMILIAR WITH THE  
FEATURES OF THE GS4000 AND ITS PROPER  
INSTALLATION PROCEDURES.  
Because all gate system installations are different, the GS4000 control  
panel provides independent connections for Open and Close non-  
contact (photoelectric) and contact (edge) sensors. In this way a  
photoelectric sensor could be utilized to guard the gate area when  
closing and an edge sensor would provide the protection when opening.  
Depending on the particular application a combination contact and non-  
contact sensor protection system for the open and close directions may  
provide more effective entrapment protection than a single device for  
both directions. See pages 4, 5, 13, 18, 24, and 25.  
The GS4000 Vehicular Swing Gate Operator is designated a Class I  
Residential Vehicular Swing Gate Operator, and is intended to operate  
a vehicular swing gate installed on a residential home, maximum of  
four single families in the dwelling, or a garage or parking area  
associated with that home. The GS4000 vehicular gate operator is also  
designated Class II (Commercial location or multi-family home); III  
(industrial location not intended to service the general public); and IV  
(secure or restricted access locations, ie. airports and prisons). The  
GS4000 may be used in any Class location.  
NOTICE - THE IMPORTANT SAFEGUARDS AND  
INSTRUCTIONS IN THIS MANUAL  
CANNOT  
COVER ALL POSSIBLE CONDITIONS AND  
SITUATIONS WHICH MAY OCCUR DURING ITS USE. IT  
MUST BE UNDERSTOOD THAT COMMON SENSE AND  
CAUTION MUST BE EXERCISED BY THE PERSON(S)  
INSTALLING, MAINTAINING AND OPERATING THE  
EQUIPMENT DESCRIBED HEREIN. DO NOT USE THIS  
EQUIPMENT FOR ANY OTHER THAN ITS INTENDED  
PURPOSE — OPERATING A SWING GATE.  
Because the Allstar GS4000 (as well as gate operators sold by other  
manufactures) is designed to start and move gates weighing as much as  
1000 pounds,---the Allstar GS4000 is capable of producing high levels  
of force. It is important in the design of the total gate system that  
designers, installers and users be aware of the hazards that may be  
associated with the IMPROPER design, installation and use of  
Vehicular Gate systems and Gate Operators.  
Audio Alarm and AlarmAble™ Open/Close Push Button Enable-  
on-Alarm Only (Patent No. 6,611,205)  
The gate operator is only one part of a complete automatic gate  
operating system. As each location and usage is different, a properly  
designed system will include all applicable safety devices.  
The GS4000 has an audio alarm that sounds when a second occurrence  
of the built-in overload activation is registered before an end limit  
(open or close) is reached. The alarm continues to sound warning until  
a fixed wire input is activated or five (5) minutes pass. As with the  
built-in overload detector, Diligent maintenance of the gate hinges and  
hardware will avoid nuisance operation of the overload detector and  
thereby avoid nuisance operation of the audio alarm. Allstar’s patented  
AlarmAble™ Open/Close Push Button Enable-on-Alarm Only feature  
can be set to provide a secure control station that will be functional in  
an emergency situation. See pages 18, 19, 24, and 25.  
The GS4000 CGA2K™ Technology provides several features that  
can help reduce the hazards of your gate system.  
Built-In Overload Detector Sensing System  
The Allstar GS4000 has a built-in "overload detector" that can help  
reduce the hazards of your gate system. This device, however, must not  
be considered as the primary defense system. Consider all available  
options (electric leading edges, photoelectric sensors, protective screen  
mesh, etc) to eliminate hazards in your gate system design.  
SMART™ Self Adjusting MAximum Run Timer  
The GS4000 has a Self adjusting MAximum Run Timer, SMART™.  
The amount of time for the first few cycles of operation are registered  
and averaged within the motor controller circuitry. After the first few  
initial cycles, if the gate is activated and no other command is given or  
an end limit (open or close) is not reached in the previously counted  
cycle time plus approximately 4 seconds, the operator will be turned  
off. See page 22.  
The Allstar GS4000 built-in overload detector will activate if there is an  
abrupt increase in motor current above that normally required to move  
the gate. The overload detection point is an adjustable setting that must  
be determined at the time of installation. This setting must be tested  
periodically to ensure proper operation. Diligent maintenance of the  
gate hinges and hardware will assure the most responsive operation of  
the overload detector. See pages 17 & 23.  
OTHER FEATURES  
Auto Close Timer: Adjustable from 2 to 60 seconds, provides an  
automatic closure of the gate from the full open position. See page 19.  
ADVISE THE PURCHASER TO CHECK THE SENSITIVITY OF  
THE OVERLOAD PERIODICALLY AND, AFTER REMOVING  
THE CONTROL BOX COVER, LOG THE DATE TESTED ON THE  
LOG LOCATED ON PAGE TWO OF THIS MANUAL (See Figure 1,  
pg. 2.)  
Timer Re-close On/Off Switch: Enables an automatic closure of the  
gate from a partially closed position if the close movement was  
initiated by the Auto Close Timer and the close cycle was interrupted  
by a non-contact (photoelectric) sensor input. See page 20.  
Diagnostic LEDs on the Motor Controller Board: Provides a visual  
indication of the status of the gate system operation. See page 20.

GATE SYSTEM DESIGN AND INSTALLATION  
SAFETY CHECK LIST:  
The GS4000 operator may be installed on a Class I, II, III, or IV  
Vehicular Swing Gate. See page 3 for an explanation of the  
different Class locations. See the last page of this manual for the  
operator specifications (voltage, maximum gate weight & length  
etc.).  
Make sure that the gate moves freely, all hinges are in good  
working order, the gate does not bind in any manner and the gate  
swing area is clean and free of irregularities. DO NOT  
INSTALL THE OPERATOR UNTIL ALL GATE PROBLEMS  
HAVE BEEN CORRECTED.  
Do not increase the built-in overload detector adjustment or  
overtighten the torque limiter to compensate for a poorly  
working gate. A well maintained gate will ensure easy manual  
operation (if needed) and maximum operator obstruction  
sensitivity.  
Figure 2  
For ORNAMENTAL “GRILL TYPE” GATES (or any other  
type of open gate where a handhold or toehold may be achieved),  
injuries may occur when people put arms through the openings or  
children “ride” the gate by standing on the bars and holding on to  
the gate. THIS POTENTIAL HAZARD CAN BE MINIMIZED  
BY INSTALLING A MESH SCREEN ON THE GATE. Allstar  
strongly recommends the entire gate and adjacent fence area the  
gate covers when open be meshed or guarded such that a  
handhold or toehold cannot be achieved. See Figure 2.  
Install the operator on the inside of the property/fence line. DO  
NOT install an operator on the public side of the fence line or  
gate. Outward swinging gates should not open into public areas.  
The gate must be installed in a location so that enough clearance  
is supplied between the gate and any adjacent structures when  
opening and closing to reduce the risk of entrapment.  
All Allstar gate operators are VEHICULAR GATE  
OPERATORS and as such are NOT RECOMMENDED FOR  
PEDESTRIAN traffic. In installations where pedestrians are  
likely to be nearby, install a pedestrian gate and use leading  
edge detectors and/or photocells in your design to protect system  
entrapment zones. Allstar can provide these products for  
incorporation in your design.  
Make sure the gate operating system is placed far enough back  
from the road to eliminate traffic backup. The distance from the  
road, size of the gate, usage level and gate cycle/speed must be  
taken into consideration to eliminate potential hazards.  
104932  
Use the illustration at left (Figure 3) to minimize the risk of  
injury in your design of the swing gate operator system.  
IDENTIFY THE ENTRAPMENT ZONES AND PINCH  
POINT AREAS IN YOUR GATE. Design the gate installation  
to minimize the risk of entrapment in these areas. Install  
additional safety equipment such as four wire edges and  
photocells to further minimize risk. All entrapment zones are  
required to be protected.  
PINCH POINTS  
Entrapment Zones: Design in personal entrapment protection  
devices to protect people from entrapment in the zones shown in  
Figure 3 at left.  
Pinch Points: Use protective measures (guards, padded edges,  
etc.) to protect people from the pinch points shown in Figure 3 at  
left.  
ENTRAPMENT  
ZONE  
SWING GATES HAVE THE POTENTIAL HAZARD OF  
HANDS AND FINGERS BEING PINCHED between the gate  
edge and the post to which the gate is mounted. It is  
recommended that the hinges be mounted so that this opening  
ELECTRIC GATE EDGE

A: GATE SYSTEM DESIGN INSTALLATION  
increases as the gate swings open. PROTECT THIS "PINCH  
POINT" SO THIS HAZARD IS AVERTED. See Figure 3.  
CONSIDER ALL OTHER "PINCH POINTS" IN YOUR  
DESIGN of the gate system. Observe the arm as it opens and the  
two arm pieces swing past each other. Use protective measures to  
reduce hazards at this location. Restrict access to the arm motion.  
See Figure 3.  
MOVING GATE  
CAN CAUSE  
SERIOUS  
INJURY OR  
DEATH  
DO NOT consider the built-in overload detector as the primary  
defense system. Consider all options in the gate system design.  
KEEP CLEAR !  
DO NOT connect any auxiliary equipment to the GS4000  
(detectors, card readers, etc.) until the gate operator and all its  
functions are fully tested. Only connect one device at a time and  
ensure its proper function(s) before moving on to the next device.  
Gate May Move at Any Time.  
Do not allow children to play  
in gate area or operate gate.  
Operate gate only when gate  
area is in sight and free of  
people and obstructions.  
104880  
DO NOT locate any control device (key switch, switch, key pad,  
card reader, etc.) in a position where it may be activated by a  
person reaching through the gate or while touching the gate in any  
manner. Locate all control devices a minimum of 10 feet from the  
gate when opened or closed.  
Figure 4  
Outdoor or easily accessible controls must be of the security type  
to prevent unauthorized use of the system.  
Install all devices that will open or close the gate in such a manner  
that THE GATE WILL BE IN FULL VIEW WHEN THE  
DEVICE IS OPERATED.

SECURELY ATTACH THE WARNING SIGNS provided with  
the GS4000 on the gate (one on the outside and one on the inside)  
where they can be seen by persons in the area of the gate to alert  
them of automatic gate operation. (If the user refuses to have the  
warning signs installed, Allstar recommends that you note this on  
your records and have the user sign a disclaimer.) See Figure 4.  
NOT PLACING IN SERVICE THIS OPERATOR IF YOU  
HAVE ANY QUESTIONS ABOUT THE SAFETY OF THE  
GATE OPERATING SYSTEM. CONSULT THE  
OPERATOR MANUFACTURER.

B: PREPARING THE SITE  
pay particular attention to the bolt pattern and the location of the  
mounting holes with respect to the center line of the gate post. It is  
critical for the proper operation of the Arm that the center line of the  
shaft of the GS4000 MECHANICAL UNIT be located exactly as  
shown on the bolt pattern drawing, Figure 6.  
THE CONCRETE PAD  
The standard GS4000 is designed to operate a single leaf gate. The  
control box and mechanical units are separate devices. It is necessary  
to find a suitable location to mount the control box, i.e., post or wall.  
Separate low voltage and high voltage conduits will be run between the  
control box and mechanical unit. (See Figure 8.)  
To properly install a bi-parting gate system, it is necessary to add one  
additional mechanical unit to the design. The control box will operate  
two mechanical units. It is necessary to run an additional low voltage  
and high voltage conduit between the two mechanical units. (See  
Figure 8.)  
104947  
Figure 6: Operator Footprint  
PLACING THE VEHICLE DETECTOR LOOPS  
If Vehicle Detectors are to be used with the GS4000, the "Loops" to be  
buried in the drive should be installed during the site preparation phase  
of the installation. Proper placement of the Vehicle Detector wire loops  
is critical if the loops are to provide satisfactory, extended service.  
THE MOST IMPORTANT CONSIDERATIONS ARE: 1) PROPER  
WIRE TYPE AND, 2) GOOD, TIGHT CONNECTIONS FROM THE  
104951  
LOOP TO THE LOOP TERMINATING CONNECTOR.  
The  
Figure 5: Pad Configuration  
termination of the loop wires will be at the Vehicle Detector itself,  
not on the GS4000 terminal board. Observe the wiring diagram  
supplied with the Vehicle Detector Manufacturer. The Vehicle  
Detector may be mounted in the GS4000 MECHANICAL UNIT. The  
AC power delivered to the MECHANICAL UNIT by the GS4000  
The Installation of the GS4000 MECHANICAL UNIT will require a  
suitable concrete pad as a mounting base. The dimensions of the  
concrete pad should be sufficient to allow at least 3" of clearance from  
each edge of the pad to the nearest operator mounting hole. The top of  
the pad should be at least 3" above grade to raise the operator above  
any standing water. The depth of the pad below grade is dependent on  
the weight and size of the gate and the soil conditions at the site of the  
installation. ALWAYS FOLLOW LOCAL BUILDING CODES.  
Control Box will NOT be satisfactory for the Vehicle Detector.  
A
separate A/C service must be provided for the Vehicle Detector.  
Two different types of Loop Installations will usually be encountered  
when placing the loops in the drive: 1) If the driveway material is  
already in place. saw cuts will be needed in which to place the loop  
wire. 2) For loops where the paving material will be installed after the  
loop is positioned, it is necessary that the loops be placed in Schedule  
40 PVC pipe to maintain uniform loop spacing with respect to the  
surface of the pavement. The loop should be placed 1.5" below the  
surface of the pavement and at least 2" above any reinforcing steel.  
The lead-in wires need not be in PVC, but must have a least six (6)  
twists per running foot.  
If no suitable concrete base exists, a pad must be poured. See Figure 6  
for plans for this pad. If the location of the operator is such that  
vehicles have the potential of hitting the operator, consideration should  
be given to installation of protective posts in front of the operator.  
If a suitable concrete base already exists for mounting the operator it  
will be necessary only to drill mounting holes for the GS4000  
MECHANICAL UNIT. 3/4" mounting holes are located on the front  
and rear of the MECHANICAL UNIT. The bolt pattern is shown in  
Figure 6. The mounting bolts should be 1/2" diameter or larger. "Red  
head" or wedge anchor concrete bolts are usually satisfactory.  
THE LOOP WIRES MUST BE CONTINUOUS. NO SPLICES OR  
CONNECTIONS IN THE LOOP ARE TO BE PERMITTED BELOW  
GROUND.  
THE ONLY CONNECTION WILL BE AT THE  
TERMINATION OF THE WIRE AT THE VEHICLE DETECTOR.  
If mounting anchor bolts are to be installed prior to pouring the pad,

B: PREPARING THE SITE  
104945  
Figure 7: Loop Diagrams  
Above ground splices may be used providing the wire is twisted,  
soldered and moisture sealed. For best long term results, do not use  
wire nuts anywhere in the loop system. Connect to the Vehicle  
Detector harness by soldering.  
VEHICLE DETECTOR LOOP BLANKING FOR  
SWING GATES  
The inside loop for a swing gate installation must be located at least  
4 feet outside of the arc of the gate. If it is not, the Vehicle Detector  
may detect the gate as it moves over the loop and cause the Gate to  
reopen. If the gate is large and a single leaf, the arc usually requires  
that the loop be a considerable distance from the closed gate position.  
This may not be an effective position for the loop. In this case, a  
“blanking” or “shadow” loop may be used.  
When a Shadow Loop is necessary, connect the output of the loop  
detector to terminal #9 “Shadow Loop” and terminal #16  
“Common”. The GS4000 circuitry will recognize a vehicle on the  
loop and prevent the gate from closing while the vehicle is over the  
Shadow Loop. When the gate is closing or opening, the GS4000  
circuitry will ignore input from this loop as the gate swings over it.  
For saw-cut installations, observe the methods recommended in  
Figure 7, above. The saw-cut must be to a depth of 1.5", clean and  
with no sharp corners. After placing the wires, it is essential that the  
wires be held tightly in place by a foam backing prior to pouring the  
sealant. THIS IS ESPECIALLY IMPORTANT WHEN FREEZING  
IS LIKELY. No voids should exist that will permit the collection of  
water that might freeze and push the loop wires out of the slot. The  
sealant used should not be hard setting and should be suitable for  
pavement material.  
THE WIRE USED FOR THE LOOPS MUST BE HEAT AND  
WATER RESISTANT, CROSS-LINK POLYETHYLENE  
INSULATED. TYPE XLPE IS BEST. RHW IS O.K. DO NOT  
USE ANY PVC INSULATED WIRE. (PVC insulation will absorb  
moisture that may affect Detector operation.) WIRE SIZE SHOULD  
BE #16 GA. STRANDED OR LARGER.

ELECTRICAL POWER REQUIREMENTS  
OTHER VOLTAGES AND 3 PHASE SYSTEMS.  
The GS4000 can be ordered for 115 Volts AC (VAC) or 230 VAC  
operation. The AWG wire size for the electrical service depends on  
the distance of the operator from the breaker panel. Refer to Table 1  
to determine the correct wire size.  
The GS4000 can operate at other voltages or on three (3) phase  
systems. To operate at 440 VAC it will be necessary to install an  
external step down transformer. The transformer should be located  
in a separate electrical box and protected by suitable circuit breaker  
and/or fusing. A 440 Volt rated switch should also be installed.  
Follow local electrical codes or the National Electrical Code. The  
transformer selected should be UL LISTED and be rated for a  
minimum 700 Volt-Amperes (Watts).

Operating from a three (3) phase line will require the use of a 230  
VAC rated GS4000. The GS4000 may be operated from a 230 Volt  
"Delta" line or a 120/208 "Y" line. In either case, ONLY one "leg"  
of the three phase line will be used. The unbalance of the line will be  
minimal since the full rate current of the GS4000 at 220 VAC is only  
2.2 amperes. (4.4 Amperes for a bi-parting system.) Connect any  
two wires of the three phase system to the 230 VAC GS4000 Tape  
the third wire carefully so that it does not short to any other object.  
(The "Y" system will have 4 wires, one of which will be the  
"common". Make sure the common is NOT selected as one of the  
wires connected to the GS4000.) It is always best to also pull a  
ground wire from the electrical service box to the GS4000 to ensure  
the frame is securely affixed to GROUND.

SERVICE CONDUIT  
Class 2 low voltage wiring from external controls such as a key pad,  
card reader, telephone entry device, etc. must be brought to the  
GS4000 CONTROL BOX by a separate conduit from the 115 VAC  
electrical hook up conduit. Low voltage control wires MUST  
NEVER be routed in the same conduit as the HIGH VOLTAGE  
power wires.  
For new installations the conduit for the High Voltage may be  
brought to a junction box near where the GS4000 CONTROL BOX  
will be located or it may be brought directly to the Control Box.  
Note! The limit switch wires from the GS4000 CONTROL  
BOX to the GS4000 MECHANICAL UNIT ARE LOW  
VOLTAGE WIRES AND MUST BE ROUTED IN A LOW  
VOLTAGE CONDUIT TO THE CONTROL BOX.

TO REVIEW: Make sure the correct position of the GS4000  
MECHANICAL UNIT from the center line of the gate hinge pivot  
point to the center line of the GS4000 is in accordance with the drawing  
of Figure 6.  
PLACING THE GS4000 MECHANICAL UNIT  
Remove the rain seal from the shaft of the GS4000. SAVE IT! The  
rain seal will be used later. Next, remove the cover from the GS4000  
MECHANICAL UNIT by removing the 1/4 inch diameter bolts on each  
side of the Unit and set it aside. It is one of the last items that will be  
replaced at the completion of the installation.  
INSTALLING THE GS4000 ARM  
Temporarily locate the Gate Bracket on the Gate with C-clamps or  
by tack welding. Install the gate bracket to the gate so the gate  
arm will be level when connected to the GS4000. See Figure 9 for  
positioning of the Gate Bracket.  
The recommended procedure for attaching the GS4000  
MECHANICAL UNIT to the concrete pad (for those installations  
where the anchor bolts were not previously installed) is first to locate  
and drill the hole for the mounting hole nearest to the gate post. Locate  
this hole by referring to the diagram in Figure 6. After placing a bolt in  
the hole, mark and drill the remaining three holes. This can be  
accomplished with the operator in place.  
Loosen the adjustment nut of the Torque Limiter located on the top  
of the Gear Box on the GS4000 MECHANICAL UNIT with the 1-  
5/8 hex socket. This is done by removing the small set screw on  
the large nut and loosening the nut.  
Before inserting the concrete bolts, make sure the GS4000  
MECHANICAL UNIT is level. If any corners of the GS4000 are  
resting above the pad, flat washers may be inserted under the  
MECHANICAL UNIT. Place the flat washers, lock washers and nuts  
on the concrete bolts and tighten securely.  
For the installation shown in Figure 9, attach the Crank Arm  
Extension to the Crank Arm with the (2) 1/4-20 x 1-1/2” long bolts  
provided. The overall length of the cranking arm is now 33 5/8”  
from the center of the Output Shaft to the center of the pivot at the  
“elbow.” Note that the cranking arm is adjustable to (5) possible  
settings: 32-1/8”, 30-5/8”, 29-1/8”, 27-5/8” and 26-1/8” long.  
For previously placed anchor bolts, the procedure is the same except  
that the bolts will already be in place. If 1/2" diameter anchor bolts  
were set, the 3/4" mounting holes on the GS4000 MECHANICAL  
UNIT will allow some adjustment for desired alignment. Washers can  
be used under the GS4000 MECHANICAL UNIT to accurately level  
the unit as above.  
Install the Crank Arm and Extension on the GS4000 main shaft and  
make sure the Crank Arm swings freely from side to side. Connect  
the Gate Arm to the Crank Arm Extension and the Gate Bracket.  
With the Gate in the closed position, the "elbow" will be up against  
the closed position stop on the Crank Arm Extension. The Gate  
should be in the properly closed position. (See Figure 9.)

DRIVE  
Loosen the Stop Pall on the large output drive sprocket located on  
the output shaft on the GS4000 MECHANICAL UNIT. (See Figure  
10.) Move the Gate to the fully open, 90 degree position. The  
Arm extension should fold back over the arm as shown in Figure 9.  
If it doesn't, some adjustment of the gate bracket or operator  
position may be necessary. With the gate in the fully open  
position, adjust the stop pall on the sprocket against the stop on the  
GS4000 frame and tighten the set screw. Open and close the gate  
several times until you are satisfied that the arm position is correct.  
Finish welding or bolting the Gate Bracket to the Gate and remove  
the C-clamps.

ELECTRICAL HOOK UP  
The GS4000 electrical connection is made at the Input Volts  
terminals in the CONTROL BOX, see Figure 11. You will need to  
drill holes as required on the bottom of the CONTROL BOX to  
permit conduit entry. Run a flexible water tight conduit from the  
service junction box to the GS4000 CONTROL BOX. Pull three #14  
wires from the service junction box in this conduit to the GS4000  
Control Box. If the GS4000 is wired for 115 Volts, pull a black,  
white and green wire. If the GS4000 is wired for 230 Volts, pull a  
black, red and green wire.

INSTALLING THE GS4000 CONTROL BOX  
The GS4000 CONTROL BOX may be mounted remotely from  
the MECHANICAL UNIT. Two mounting holes are provided  
on each flange of the CONTROL BOX (four total). These  
should be used to mount the CONTROL BOX to a solid, flat  
surface. The CONTROL BOX should be located so that the

lines. Effective protection requires that the surge current from the  
lightning strike be shunted to ground. This must be done without  
raising the potential of the circuitry in the GS4000, with respect to  
ground, to the levels that will damage the solid state circuitry.  
Lightning strikes generate enormous currents for very short periods  
of time. Unfortunately, the period of time is long enough to damage  
solid state components and many times, other components. The key  
to success is a very low resistance path from the surge protector to  
ground for these currents in addition to a surge protector that will act  
fast enough to protect the solid state circuitry. Several manufacturers  
offer suitable surge protectors.

proceed as follows:  
RIGHT HAND AND LEFT HAND INSTALLATION  
The GS4000 Control panel is configured at the factory for right hand  
operation - mechanical unit mounted to the right of the gate leaf as  
you look at the installation from the inside (secured side). For left  
hand operation - mechanical unit mounted to the left of the gate leaf  
as you look at the installation from the inside (secured side) - move  
the 8 pin high voltage harness connector (white) and the 3 pin limit  
harness connector (orange) from the right hand connector blocks on  
the control board to the left hand connector blocks, see Figure 12,  
below.

motors will be turned off.  
A wiring schematic of the Bi-Parting installation is shown in Figure  
15, page 14. It is important this schematic be followed closely and  
that the color codes at the MECHANICAL UNITS and the  
CONTROL BOX be followed exactly. Most of the difficulties  
encountered with Bi-Parting installations are due to the wiring  
instructions not being followed.  
ACCESSORY EQUIPMENT HOOK-UP  
All accessory equipment is connected to the 18 terminal barrier strip  
located inside the GS4000 Control Box. To expose this terminal  
strip, remove the cover on the Control Box.  
There are 13 command inputs (#3 through #15) available to the  
installer on the GS4000 in a addition to a common terminal (#16).  
To trigger any of these inputs, a switch or relay closure to the  
common terminal for a duration longer than 100 milliseconds and of  
a resistance of less than 100 ohms is necessary. Eight of the inputs,

BI-PARTING WIRING  
For a Bi-Parting installation, an additional two conduits must be  
installed between the First Mechanical Unit and the Second Mechanical  
Unit. (See Figure 8, page 8.) For a Bi-Parting installation, one operator  
must be a Left Hand unit and the other a Right Hand unit.  
The two motors of the Bi-Parting GS4000's will be wired in parallel.  
BOTH motors will run until both are shut off. If the two gate leafs do  
not open exactly the same amount, then the first gate leaf to reach it's  
open position will have to be held (or mechanically stopped) in that  
position until the second gate reaches its open position. Now, both  
motors can be turned off. The stop for the first gate can be installed  
externally or the GS4000 internal Stop Pall mounted on the large output  
drive sprocket of the GS4000 may be used.  
The Limit Switch contacts of the two Bi-Parting units need to be wired  
in series. Both limit switch contacts must be closed before a connection  
is made to the limit switch input at the Control Box to stop the motors at  
the Open or Closed position.  
The operation of the Bi-Parting installation is as follows: After receipt  
of a command to open, both units will begin to open together. The first  
gate to reach its open position will be stopped by the mechanical  
stop. Its motor will continue to run. The Torque Limiter will be  
adjusted to slip when the stop is encountered with the motor still  
running. The limit switch contact on this first unit is adjusted to  
close at this position. The second gate has not reached its fully  
open position. Its limit switch will be still open and no command  
will be given to the limit switch input at the terminal board until the  
gate has reached the maximum open position and the open limit

main power switch is ON. The maximum power that can be  
supplied by the transformer for an accessory equipment item is  
20 VA or about 1 Ampere at 24VAC. This is usually sufficient  
to supply an accessory equipment item such as a radio receiver.  
Check the equipment for its power specifications.

SETTING THE LIMIT SWITCHES  
With the cover removed from the GS4000 MECHANICAL UNIT,  
and the arm connected to the gate as well as to the GS4000 Operator,  
position the gate at its FULLY CLOSED position. Identify the  
lower Limit Switch. Loosen the clamping nut on the Limit Switch  
Cam for the lower Limit Switch. Rotate the cam on the output shaft  
until it engages the Limit Switch and an audible “click” is heard.  
Repeat this several times until you are confident that the position of  
the cam is such that the Limit Switch is just closed. Carefully tighten  
Figure 22: SETTABLE SWITCHES  
NO-LOAD TEST MODE  
To run/test the GS4000 operator when it is not connected to a gate  
leaf, turn all of the switches to the “ON” position. The GS4000 can  
then be operated without a gate leaf attached for 20 complete cycles.  
If more that twenty cycles are attempted in the test mode the operator  
control board changes to a “sleep” mode and a low pulsed tone is  
heard from the audible output. You can reset the operator for a  
renewed 20 test cycles by turning the power off and back on again.  
To return to normal operation turn one of the switches to the “OFF”  
position, then set all the switches to the desired mode of operation as

APPLYING POWER TO THE GS4000  
PRE-POWER CHECK LIST  
110125  
Before applying power to the GS4000 for the first time, go through  
the following check list to ensure that all is in order for the application  
of power.  
1. Check that the GS4000 power switch is off.  
2. Check that the breaker at the power panel is on.  
LOCATION OF  
AUTOCLOSE TIMER  
ADJUSTMENT  
3. With a voltmeter on the proper scale, check that the line voltage at  
terminals L1 and L2 on the GS4000 control board is the voltage that is  
expected. Connection of a 115 VAC GS4000 to an unexpected 230  
VAC line is a common occurrence.  
This will cause readily  
identifiable board failure that WILL NOT BE COVERED UNDER  
WARRANTY.  
4. Manually move the gate to the center of the gate opening.  
Figure 23: Location of Auto-Close Timer Adjustment  
5. Make sure the Torque Limiter is properly adjusted to slip under a  
load when a moderate amount of force is applied to the gate in the  
center of its travel. If the adjustment is too loose, the overload  
sensitivity will not function properly and the Torque Limiter may slip  
when the gate is under a wind loading. Start by tightening the large  
nut on the Torque Limiter to 35 ft-lbs./in. To fine tune, increase or  
decrease this by approximately 5 ft-lbs./in. increments. When a  
satisfactory setting is found, tighten the set screw in the side of the  
large nut.  
TIMER TO CLOSE SETTING  
The Timer to Close is controlled by the setting of the “AUTO CLOSE  
TIMER” potentiometer on the control board, see Figure 23. When the  
pot is adjusted fully counter-clockwise the Timer-To-Close is  
disabled. Turning the pot approximately 1/4 turn clockwise will  
enable the Timer To Close function with a delay of approximately 2  
seconds between the gate reaching the full open position and  
automatically closing. To increase the time delay continue to turn the  
pot in the clockwise direction to a maximum delay of 60 seconds (one  
minute).  
6. Set all the Switch selectable options switches ON for the test mode.  
7. Make sure that the overload sensitivity potentiometers (Open and  
Close) are set to their preliminary start up position.  
8. Temporarily remove the white high voltage connector from the  
control board.  
AUTO RE-CLOSE (TIMER-TO-CLOSE FUNCTION)  
Switch S2 controls the Auto-Re-close function. If the Timer To Close  
function is enabled (see above), setting Switch S2 to the ON position  
will activate the Auto-Re-close feature on the motor control board.  
When the auto-re-close is activated, the gate will re-close after  
stopping and backing-off from a non-contact sensor input if the close  
movement was initiated by the Timer-To-Close function on the  
control board. The gate will not re-close if the sensor input was  
received from a contact sensor or if the inherent overload sensor was  
activated.  
CHECKING THE INDICATOR LIGHTS  
There are 16 indicator lights on the control board of the GS4000. See  
Figure 24. These lights are used to verify proper operation of the  
GS4000.  
TURN ON THE MAIN POWER SWITCH TO THE GS4000.  
MASTER/SLAVE CONFIGURATION  
Note that the “POWER” lamp is lighted. This indicates that power  
is applied to the control board and the power supply is functioning  
Switch S3 controls the Master/Slave Terminals (#s 14 & 15)  
configuration setting. The setting is used when two control boards  
(boxes) are used in conjunction with two mechanical units.  
1. Connect one end of a short piece of wire (not supplied) to terminal  
#16 (COMMON).  
2. With the other end of this wire, (make sure that this loose end is  
free of insulation), touch the following terminals and observe the  
noted response of the lamps.  
With Switch S3 in the ON position terminals 6 & 7 (OPEN &  
CLOSE) are in the Slave mode and could be coupled to and would be  
controlled by a Master control board (box). With Switch S3 in the  
OFF position terminals 14 & 15 are in the Master (output) mode and  
could be coupled to and would control a Slave control board (box).

If the gate stops short of the desired fully open or closed position  
or if it bangs against the end stops, TURN OFF THE MAIN  
POWER and reset the appropriate Limit Switch Cam. After you  
have attained the final adjustment, run the GS4000 open and closed  
several times to ensure that the positions set will be retained.  
USE CAUTION DURING THIS FINAL  
ADJUSTMENT PERIOD.  
SMART™ SETTING - MAXIMUM RUN TIMER  
The GS4000 is equipped with a Self adjusting MAximum Run  
Timer, SMART™ , that will turn the GS4000 OFF if a Limit Switch  
command is not received within five seconds of the time required to  
fully Open or Close the gate. The purpose of the Maximum Run  
Timer is to turn off the GS4000 if the gate should become jammed  
when opening or closing. In this case, the Limit Switch will not be  
activated. Should this occur, the Torque Limiter will slip and the  
pads will be worn out prematurely. The Maximum Run Timer will  
prevent this by turning OFF the GS4000. Once the obstruction is  
removed, any command will reactive the GS4000.  
PRE RUNNING CHECKLIST  
Before running the GS4000, make sure:  
1. The proper Left-or Right-hand or Bi-Parting wiring has been  
completed (if applicable).  
2. The Limit Switch Cams have been preliminarily set.  
3. The Overload Sensitivity has been preset.  
4. The Switch Selectable Options have been set.  
5. The Gate has been positioned in the center of it's travel.  
6. The Torque Limiter is properly adjusted.  
To set the Smart™ Maximum Run Time fully open and close the  
gate five (5) times. The control board will sense the time required  
and add approximately four seconds.  
7. No other devices should be connected to the terminal strip  
until the powering-up procedures are completed.  
WHEN CHECKING OPERATION OF THE LIMIT  
SWITCHES, BE CERTAIN THE MOTOR IS BEING  
TURNED OFF BY THE LIMIT SWITCH AND NOT THE

3. If the TIMER TO CLOSE is not to be used on this installation,  
activate the gate to Close by connecting the jumper wire from  
Terminal #16 (COMMON) to Terminal #7 (CLOSE). The gate  
should move to the fully closed position.  
To alter the amount of time that the close timer will hold the gate  
open, adjust the timer potentiometer located on the Control Board.  
See Figure 23, page 20.  
4. Allow the gate to close and note the position of the gate.  
The Close Timer is adjustable from 2 to approximately 60 seconds.

FINAL SETTING OF THE MOTOR OVERLOAD  
SENSITIVITY  
The motor overload sensitivity was preset for each direction before  
turning on the main power to prevent the operator from "self-  
tripping" during the preliminary adjustment period.  
You are now ready to install and connect the ancillary  
equipment.  
SECTIONS A, B,  
BEFORE PROCEEDING.  
INSTALLATION STEPS DETAILED IN  
C
AND MUST BE COMPLETE  
D
Adjust the Open Overload Force potentiometer, see Figure 20 fully  
counter-clockwise then approximately 1/16 of a turn in the clockwise  
direction. Start from the closed gate position and give the GS4000 an  
open command and observe the Gate. If the gate stops and reverses  
anywhere in the cycle turn the Open Overload potentiometer  
approximately 1/16 in the clockwise direction. Repeat this process  
until the gate will open without the Open Overload tripping and with  
the Open Overload potentiometer in the most counterclockwise  
direction. (Make sure the gate swings easily and there are no  
obstructions in the path of the gate.)  
1. Installing Entry Devices  
After you are satisfied that all the loops are functioning properly,  
proceed with the installation of any additional entry devices, such as  
a Radio Receiver, Telephone Entry or Key Pad. Connect the Radio  
Receiver and observe the precautions regarding radio receivers  
described on page 15. Other entry devices MUST be connected to  
the appropriate terminal(s) as their functions warrant as described on  
pages 17 through 19.  
Repeat the above adjustment procedure for the close direction.  
2. Installing a Magnetic Lock  
CAUTION: During this process the alarm will sound if the overload  
sensor is activated two sequential times before the gate reaches a  
limit (open or close). To reset the alarm sensor use constant pressure  
on a control button connected to the OPEN or CLOSE input and  
move the gate to a fully open or closed position or turn off and  
restore the power to the operator.  
The GS4000 can (as an option) be configured and wired to provide a  
closed contact to control the power to a Magnetic Lock. This option  
must be ordered at the same time as the operator or as a kit  
installation after the original installation.  
The magnetic lock must be powered by an external source, the  
operator provides only a contact to energize and de-energize the lock.  
When you are satisfied that you have the best settings, test these  
settings by striking the gate a sharp blow with the palm of your hand  
in both the open and close direction. The OVERLOAD should  
respond immediately to your blow. If the Torque Limiter slips before  
the overload is detected, the Torque Limiter will need to be tightened.  
The purpose of the Torque Limiter is to protect the mechanical  
components of the GS4000 (primarily the Gear Box). The Torque  
Limiter should be adjusted so that the OVERLOAD will be activated  
before slippage occurs.  
Note: the Allstar GS1000 (slide gate operator) uses the same Control  
Board as the GS4000, except for the configuration of the LOCK  
circuitry. If the LOCK is energized when the gate is opening or  
closing, a GS1000 Control Board has been accidentally installed in  
your GS4000 operator. It must be replaced with a GS4000 BOARD.  
The Magnetic Lock will be released by the GS4000 about 100  
milliseconds prior to giving the gate an Open Command. This time  
delay is to allow the magnetic field in the Magnetic Lock to decay  
and release the Lock prior to starting the gate.  
IMPORTANT !  
THE OVERLOAD POTENTIOMETERS  
MUST BE ADJUSTED TO THE MOST SENSITIVE  
POSITION POSSIBLE WITHOUT CAUSING "SELF-  
TRIPPING" DUE TO THE GATE'S INHERENT FRICTION  
OR TO VARIATIONS IN THE GATE HINGE.  
TRY  
ADJUSTING THE POTENTIOMETERS SEVERAL TIMES  
BY SMALL INCREMENTS, TESTING THE OVERLOAD  
BY STRIKING THE GATE WITH YOUR PALM IN BOTH  
DIRECTIONS OF TRAVEL. REPEAT THIS TEST UNTIL  
YOU ARE SATISFIED YOU HAVE THE MOST  
SENSITIVE SETTING OF THE POTENTIOMETERS.  
Disconnect the crank arm from the output shaft to permit re-  
installation of the cover on the mechanical unit. Install the operator  
cover and secure it to the frame with (2) 1/4-20 hex bolts. Remember  
to re-install the rain seal on the output shaft. Re-connect the gate arm  
on the GS4000 and secure it with the padlock provided. Complete  
the installation by replacing the cover on the Control box.

IMPORTANT SAFETY INSTRUCTIONS. TO REDUCE THE RISK OF SEVERE INJURY OR  
WARNING!  
DEATH: READ AND FOLLOW ALL INSTRUCTIONS IN THIS MANUAL!  
Instructional and precautionary signs  
Covers for exposed rollers  
To the Owner/End User of Allstar’s GS4000:  
Thank you for choosing an Allstar product. We are confident you will  
have many years of use and satisfaction with your gate operator.  
Each safety feature is a separate component in your gate system. Read  
and follow all instructions for each of the components of your unique  
system. Ensure that all instructions for mechanical components,  
safety features and the Allstar GS4000 are available for everyone  
who will be using your gate system.  
Your GS4000 Operator is part of your unique gate operating system,  
which may consist of a variety of components, including the gate, the  
gate tracks, posts, and electronic safety features. These components  
combined present certain risks and safety issues of which you, the end  
user, must be aware.  
The two warning signs shipped with your GS4000 Operator (See Figure  
4, Page 5 of this manual) must be installed in prominent positions on  
both sides of your gate. Keep them clean and legible.  
Read and put into practice the safety points that follow which present  
the basic guidelines for the safest operation of your gate operator  
system.  
Each unique system presents a unique set of hazards which we cannot  
possibly address individually. These instructions will help you to  
identify the potential risks and safety issues your gate operator system  
presents, and guide you as you make your system as safe as possible for  
everyone who uses it.  
SAVE THESE INSTRUCTIONS !  
Your first step is to consider the intended use of the gate system, who  
will be using the gate system, and in what manner the system is  
installed. You should have a clear understanding of how often the gate  
will be opened, who will be opening it, whether children and the  
general public will be near the gate system, and how close the gate  
system is to public property. Once you have answered these questions,  
you are ready to decide what safety measures must be taken to prevent  
injury.  
AVOID ENTRAPMENT: Stay away from the path of the gate  
and all moving parts (gate arms, etc.) at all times. Keep clear of the  
pinch points identified below.. Install guards or other safety features to  
prevent access to pinch point areas. Install guards on open rollers.  
PREVENT PERSONAL INJURY OR DEATH: Do not stand  
near or on the gate. Gate may be activated without notice. Do not  
allow anyone to “ride” the gate, or place arms or legs through the gate. The  
force of the gate can cause serious personal injury or death. No one should  
cross the path of a moving gate.  
To minimize the risk of entrapment in your gate system, install the  
following safety features:  
NO CHILDREN OR PETS ALLOWED: Never allow a child to  
operate gate controls, “ride” a gate, or play in the area of a gate.  
Install and store all controls out of children’s reach. Also, pets must be  
kept away from the gate. Install a pedestrian gate in applications where  
children or pets need access.

PRECAUTIONS FOR PEDESTRIAN TRAFFIC OR RESIDENTIAL AREAS.  
The internal operator overload sensor may not be adequate entrapment protection in all situations to prevent arm,  
leg, or hand injuries. Padded electric gate edges, pneumatic gate edges, or photoelectric sensors are therefore  
necessary when automatic gates are used near pedestrian traffic. See the figure below. Use of a pedestrian walk gate  
is mandatory where there is nearby pedestrian traffic.

MAINTAIN THE GATE AND GATE HARDWARE:  
A
ALL APPROPRIATE SAFETY FEATURES MUST BE  
INCORPORATED INTO YOUR GATE SYSTEM.  
damaged gate or one that cannot be easily opened and closed  
manually must be repaired before installing a gate operator. A poorly  
operating gate may cause the load sensing device of the operator to fail,  
causing a risk of entrapment. Never overtighten the clutch or load sensing  
device to compensate for a poorly swinging gate. Correct all mechanical  
problems on the gate and gate hardware before installing the gate operator.  
Have a qualified service technician make repairs to the gate.  
KEEP GATE IN SIGHT: Never activate the gate unless it is in  
sight. Install mounted controls in full view of the gate. Be sure the  
gate area is clear before activating the gate, and watch the gate and gate area  
as the gate is in motion.  
LOCATE MANUAL CONTROLS SAFELY:  
A manual  
MAINTAIN ALL COMPONENTS OF GATE SYSTEM:  
Follow the maintenance instructions included with the gate, the  
control such as a pushbutton or keyswitch must be included in  
your gate system design to be used if automatic controls such as radio  
controls or loop detectors do not function. Carefully consider the placement  
of the manual control: It must be out of reach of the gate so that no one  
pushing the button or inserting the card is in the path of the gate or moving  
parts; it must also be within sight of the gate so that the operator can watch  
the gate and gate area during operation. The recommended minimum  
distance between the gate or fence and manual controls accessory is 10  
gate operator, and the safety features and/or accessories that make up your  
gate operator system. Have a professional service technician perform any  
adjustments or maintenance to the components. Fully test all safety  
features monthly. Discontinue the use of faulty safety equipment  
immediately, and have the equipment serviced or replaced. by a qualified  
service technician. The gate must reverse on contact with a solid, rigid  
object or when an object activates the non-contact sensors. After adjusting  
the force or limits of travel, retest the gate operator. Failure to adjust and  
retest the gate operator properly can increase the risk of injury or death.  
KNOW YOUR GATE ARM DISCONNECT FEATURE FOR  
MANUAL OPERATION: In the event of a power outage, you  
may need to manually operate your gate. The GS4000 is equipped  
with a keyed padlock to permit the gate arm to be manually disconnected  
from the GS4000 operator. This will allow you to manually push the gate  
open or close as needed. Be sure to have the service technician or dealer  
installing your gate system give you the key to the padlock and show you  
how to use this feature quickly and safely. Keep the key in a safe,  
accessible place. Manual operation is to be attempted only when the  
operator is not moving the gate under power.  
INSTALL SAFETY DEVICES: In residential applications or in  
areas where pedestrians may be present, or if your gate closes  
automatically, be sure an electric edge(s) and/or a photoelectric sensor(s)  
has (have) been installed and is/are operating properly. These features are  
intended to detect pedestrian traffic and prevent injury or entrapment.  
Loop detectors may be installed to detect vehicular traffic and prevent  
vehicular damage.  
Sensor, Open Contact Sensor input or an Open Overload activation will  
cause the gate to stop, pause and reverse for approximately 2 inches in  
the Open direction.  
If the gate is moving in an Open direction a Stop or Alternate input will  
cause the gate to stop. A subsequent Alternate input will cause the gate  
to begin moving in the Close direction.

Reversing, or Free Exit Loop input will cause the gate to stop, pause  
and reverse and run in the Open direction.  
Two sequential activations of the Overload detector (Open or Close  
direction) before the gate reaches a limit will cause the operator to go  
into the alarm mode. To reset the operator remove the obstruction and  
either use constant pressure on a control button connected to the OPEN  
or CLOSE input and move the gate to a fully open or closed position or  
turn off and restore the power to the operator.  
If the gate is moving in a Close direction a Stop Button or Alternate  
input will cause the gate to stop. A subsequent Alternate input will  
cause the gate to begin moving in the Open direction.
