screws.
8. Reconnect all terminal blocks and coaxial cable.
9. Reconnect battery connectors. Verify the DIAGNOSTIC LED blinks.
10. Reconnect power to operator.
11. Reinstall control box cover and secure with screws.
12. Learn the limits for the gate operator (refer to detailed instructions
on next page). Program all remote controls.
13. Test the force adjustment.
14. Verify all other inputs and outputs as necessary (safety sensors,
edges, loops, locks, alarm, reset, accessory power, open and single
button).

PROGRAMMING
PROGRAM LIMITS
2
The limits are internal settings that indicate when the gates are in the fully open position and the fully closed position. For proper functionality, the
limits must be programmed during the installation process. The programming uses a combination of buttons on the control board.
The specific buttons used for programming depends on which side of the gate the control box is mounted and how many operators the installation
includes. Refer to pages 11 and 13 to determine if the gate is Left- or Right-handed.
If a mistake is made during programming press the RESET button on the outside of the control box to start over.
SINGLE ARM LEFT-HAND SIDE SINGLE ARM RIGHT-HAND SIDE
NOTE: The programming can be exited at any time by pressing the RESET button. The programming times-out automatically after 60 seconds of
inactivity.

NOTES:
• If one gate is overlapping the other, the gate that is overlapping must be connected to GATE 1 so it will start moving before the other gate; gate 2
may need to be closed first if there is overlap or a gate lock is being used.

FORCE ADJUSTMENT
The operator is equipped a with an obstruction sensing feature. If the gate
encounters an obstruction the operator will automatically reverse direction
and stop. Based on the length and weight of the gate it may be necessary
to make force adjustments. The force adjustment should be high enough
that small objects such as branches or wind will not cause nuisance
interruptions but low enough to prevent serious injury to a person or a
vehicle.
To adjust the force:
Using the 3-button remote or the Single Button Control (SBC) button
on the control board, open and then close the gate. If the gate stops
or reverses before reaching the fully open or closed position increase
the force by turning the force control slightly. Run operator through a
complete cycle.
NOTE: Weather conditions can affect the gate movement, so seasonal
adjustment may be required. The force
control is factory set to the mid position.
TIMER-TO-CLOSE (TTC)
The TIMER TO CLOSE feature can be set to automatically close the gate
after a specified time period. The TTC is factory set to OFF.
If the TTC is set to the OFF position, then the gate will remain open until
the operator receives another command from a remote control or SBC.
TO SET THE TIMER TO CLOSE:
Rotate the TIMER TO CLOSE dial to the desired setting. The range is 0 to
180 seconds, 0 seconds is OFF.
NOTE: Any radio command, SBC, or CLOSE command on the control
board prior to the TTC expiring will close the gate. The TTC is reset by
any signals from the loops, close edges, and close safety sensors (IR’s).
Without a properly installed safety reversal system, persons
(particularly small children) could be SERIOUSLY INJURED or KILLED
by a closing gate.
• Too much force on gate will interfere with proper operation of safety
reversal system.
• NEVER increase force beyond minimum amount required to close
gate.
• NEVER use force adjustments to compensate for a binding or
sticking gate.
• If one control (force or travel limits) is adjusted, the other control
may also need adjustment.
• After ANY adjustments are made, the safety reversal system MUST
be tested. Gate MUST reverse on contact with a rigid object.

NOTICE: To comply with FCC and or Industry Canada (IC) rules, adjustment or modifications of this
receiver and/or transmitter are prohibited, except for changing the code setting or replacing the
battery. THERE ARE NO OTHER USER SERVICEABLE PARTS.
Tested to Comply with FCC Standards FOR HOME OR OFFICE USE. Operation is subject to the
following two conditions: (1) this device may not cause harmful interference, and (2) this device
must accept any interference received, including interference that may cause undesired operation.
To Add or Reprogram a Remote Control (not provided)
1. Press LEARN XMITTER button and release (LED will light up).
2. Press remote button, the LED will flash, alarm output will activate
twice.
3. Repeat steps 1 and 2 until all remote controls
are programmed (50 remote controls
maximum).
NOTE: For highest level of security, we recommend
the Security® line of products. Refer to
Accessories.
To Add a Wireless Keyless Entry (not provided)
1. Press LEARN XMITTER button and release (LED will
light up).
2. Enter a four digit personal identification number (PIN)
of your choice on the keypad.
3. Then press ENTER, the LED will flash, alarm output
will activate twice.
TO ERASE ALL CODES
To deactivate any unwanted remote controls or keyless entries, first erase
all codes:
Press and hold the LEARN XMITTER button on control board until the
learn indicator light goes out (approximately 6 seconds). All previous
codes are now erased. Reprogram each remote control or keyless entry
you wish to use.
1. To prevent possible SERIOUS INJURY or DEATH from a moving
gate or garage door:
• ALWAYS keep remote controls out of reach of children. NEVER
permit children to operate, or play with remote control transmitters.
• Activate gate or door ONLY when it can be seen clearly, is properly
adjusted, and there are no obstructions to door travel.
• ALWAYS keep gate or garage door in sight until completely closed.

1. READ AND FOLLOW ALL INSTRUCTIONS.
2. NEVER let children operate or play with gate controls. Keep the
remote control away from children.
3. ALWAYS keep people and objects away from the gate. NO ONE
SHOULD CROSS THE PATH OF THE MOVING GATE.
4. Test the gate operator monthly. The gate MUST reverse on contact
with a rigid object or stop when an object activates the non-contact
sensors. After adjusting the force or the limit of travel, retest the
gate operator. Failure to adjust and retest the gate operator properly
can increase the risk of INJURY or DEATH.
5. Use the emergency release ONLY when the gate is not moving.
6. KEEP GATES PROPERLY MAINTAINED. Read the owner’s manual.
Have a qualified service person make repairs to gate hardware.
7. The entrance is for vehicles ONLY. Pedestrians MUST use separate
entrance.
8. Disconnect ALL power BEFORE performing ANY maintenance.

To reduce the risk of SEVERE INJURY or DEATH:
TEST
1. Verify gate operator functions properly.
2. Test the safety reverse. Gate must reverse on contact with a rigid object. If the gate stops on the obstruction, reprogram
the Forces or limits.
NOTE: If the gate hits 2 consecutive obstructions, the operator will stop, the entrapment alarm will sound. No commands
at this time will operate gate. The operator will require resetting. The reset button is located on the outside of the control
box. After the operator is reset, normal functions will be available. The alarm will sound for up to 5 minutes (operator will
still need to be reset).
For complete troubleshooting information refer to the owner’s manual.
