  • Read this installation manual completely prior to installation.

  • Installation should be performed by a professional installer.

  • Required welding should be performed by a qualified welder.

  • Should electricity be required use a certified electrician only.

  • Any device that requires 120 Volts AC should be U.L. approved.

  • Review with the owner all safety concerns including:

  1. Do not operate the gate unless area around gate is in full view.

  2. Do not allow children or adults to "ride" on gate during operation.

  3. Do not allow children to play in the gate area.

  4. Periodically test the obstruction sensitivity to assure safe and proper operation. Do not test sensitivity by standing between the gate and the hinge or stop post.

  5. Do not allow children to play with the gate controls.

  6. The 'CAUTION AUTOMATIC GATE" sign should be clearly visible from both sides of the gate.

  7. Always insure that the gate has closed securely before leaving area.

  8. Arrange with local fire and law enforcement for emergency access.

  • Recommend safety devices such as loop detectors, edge switches, and beam detectors when applicable

  • Install control devices such as keypads far enough away (5 feet or further) from any moving parts of the operator and gate to prevent possible injury

  • Always disconnect the battery or power source when making adjustments or repairs to any part of the gate or operation

  • All rollers should be covered to prevent injury




The Apollo Model 1500/1600 Swing Gate Operator is designed to handle swing gates up to 16 feet in length and 600 pounds each A professional fence or gate dealer is recommended to assure proper installation Apollo Gate Operators are available only through qualified dealers with an outstanding reputation in the fence and gate industry These dealers will be able to recommend the proper equipment for particular applications Apollo Gate Operators are 12 Volt DC (Direct Current) powered A 12 Volt marine type battery with connecting posts  located on the top is recommended There are several advantages with 12 Volt DC systems:

  • Low voltage virtually eliminates risk of electrical shock.

  • Battery powered operators provide up to 200 operations in the event of power outages.

  • The battery may be recharged with a trickle charger or by solar energy (eliminating the need for costly trenching to remote entrances).

If a trickle charger is used and a standard electrical outlet is not readily available, a licensed electrician will be required for proper electrical hook up.

The following table should be used as a guide for capacity of  operation of operators only, additional options may reduce the the daily usage. Please note that the charge capability of solar panels will vary with different geographical locations.

Charging Methods for Average Daily Usage

The following checklist should be used before beginning installation:

Verify that the proper operator has been selected for this application.

Verify proper installation and operation of the gate.

  1. Are the hinges serviceable?
  2. Does the gate swing free and level?
  3. Will the gate require a locking device?
  4. Is the hinge and stop posts sturdy enough to handle the gate & operator?

Determine the general location of the operator, attachment points, and solar panel (if used).

  1. Is there a suitable location for the operator?
  2. Can the solar panel (if used) be mounted in an unobstructed area facing south (in the northern hemisphere)?
  3. Will additional solar panel cable be required?
  4. Is electricity available (if required)?

Consider safety and access options. Recommend if needed.

  1. Will there be children or animals in the area?
  2. Are safety loops, edge switches, or photo beam detectors required?
  3. How can the gate be opened in emergencies?
  4. How will visitors enter and exit?
  5. Will vehicles (and trailers) have sufficient room off roadway to operate any control devices such as keypads?








PIVOT ARM INSTALLATION (standard pull to open)

Location of Pivot Point

PULL TO OPEN pulls gate open (actuator is extended when gate is in the closed position). PUSH TO OPEN pushes the gate open (actuator is retracted when gate is in the closed position). For PUSH TO OPEN installations see page 11.

It a 400 Upgrade Kit is to be used refer to the 400 instructions for pivot point location, The following instructions provide up to 105 deg. of swing,




Control Box Installation

Mount the control box within 4 feet of the pivot arm
Use mounting hardware capable of supporting the
weight of the control box with the battery installed

Mounting holes are not provided since mounting surfaces will vary

Set battery inside of control box with terminals toward
the front (Do not use any battery with side terminals)


Connecting the Actuator (s)

Connect actuator cable to the MASTER connector on the control board.

If a 1800 is being installed and conduit is being used under the drive (recommended) cut the slave (opposite side where control box is mounted) actuator cable about 12 from the white connector. Run the remaining cable across the drive through conduit and up through the control box. Cutoff any excess cable and splice the short piece back to the cable. Connect to the "SLAVE" connector on the control board.

Connect the RED power wire (s) to the battery positive ( +)
and the BLACK power wire (s) to the battery negative ( -)






Activate push button on the side of the control box and extend the actuator until it stops (PULL or OPEN
only, leave actuator retracted for PUSH or OPEN).

Align the hole in the end of the actuator extension
tube with the holes in the gate bracket and locate gate bracket mounting position with the gate in the closed position. Weld or bolt the gate bracket to the gate using 3/8" bolts, lock washers, and nuts.

Tip Tack weld or C clamp at first if uncertain about location. Run the unit through a complete cycle to insure proper operation then mount permanently.

Bolt the actuator to the gate bracket as shown.

Bracket should attach 52" - 54" from the center of the hinge.

WARNING: Do not let extension tube rotate as it extends. Do not insert fingers or tools in the hole at the end of the extension tube!



Cycle the operator and adjust limits as required.  If  the operator opens automatically after closing, extend less until gate remains closed.

Do not retract the extension tube too far or the retract 
limit switch will not be activated.

1600 Adjustments

As you open and close the gates, you will notice that the slave side moves 2-3 seconds slower than the master.

Tip - By welding stop tabs on the top and the bottom of the master side, the two gates may now be adjusted so the slave gate will close against the stop tabs of the master gate and create enough tension to prevent gates from moving back and forth.

WARNING: The AUTO REVERSE SENSITIVITY should be adjusted to prevent injury in the event of someone being entrapped in the gate. This feature should be periodically tested to assure proper operation. Refer to SAFETY PRECAUTIONS,


There are 4 standard automotive type fuses on the 635/636 circuit
board The EMERGENCY BYPASS plug is protected by a 15 Amp
fuse The remaining three fuses (one for each of the 12 Volt outputs) are 2 amp and may be replaced with 3 amp if necessary.







Do not confuse the receiver code switches with the red program switches on the gate control board. Never set all code switches to the same position. Transmitters must match code switches for proper operation.  If power is taken directly from battery or connected as shown below, receiver should be configured for 12VDC.




Some troubleshooting will require a hand held multimeter. An inexpensive digital multimeter may be purchased at Radio Shack or a local electric supply company. 
Refer to the owners manual for instructions
