Operation and Maintenance

Using Your Gate Operator

Your operator will operate with up to nine Security

✚

remote controls and one Security

✚

Keyless Entry System.

If you purchase a new remote, or if you wish to deactivate
any remote, follow the instructions in the Programming
section.

Activate your operator with any of the following:

Hand Held Remote Control (See Accessories):

Hold

push button down until the gate begins to move. While gate
is moving, the next command sent from the remote will stop
the gate. Next command will reverse the gate direction.

Keyless Entry (See Accessories):

If provided with your

gate operator, it must be programmed before use. See

Programming

Vehicle Exit Sensor:

See accessory page.

Entrapment Features

When the operator is activated (with the safety sensors
correctly installed and aligned) and the safety sensors
encounter an obstruction, the following will occur:

Opening Cycle:

Gate will stop, reverse direction for

approximately 2 seconds and then stop. The next
command will continue the gate in the close direction.

Closing Cycle:

Gate will stop, reverse direction for

approximately 2 seconds and then stop. The next
command will open the gate.

Alarm Sounds

The operator alarm will sound under the following condition:
If gate encounters two consecutive obstructions, the
operator will stop, the alarm will sound (up to 5 minutes)
and the control board will require resetting. Reset the
control board by pressing the “Reset Button” located on the
outside of the control box. No commands at this time will
operate gate. After the operator is reset, normal functions
will be available.

Automatic Timer To Close Feature

The Timer-To-Close (TTC) Feature comes
from the factory in the OFF setting.

The “TIMER RUNNING LED” will flash once
for every second of adjusted time. The gate(s)
must fully open for the timer feature to be
active and close the gate(s). Any radio
command or pressing the single button on the control
board prior to the TCC time expiring will close the gate.
The TTC is reset by any signals from the loops, close
edges, and close safety sensors (IR’s).

Party mode

If the Timer-to-Close feature is enabled and you would like
the gate to remain open, simply push the reset button
(located on the outside of the control box). The next
command given to the operator will close the gate and
return the operator to normal operation.

Sleep mode (battery conservation)

Sleep Mode (Battery Conservation):

The operator enters

sleep mode 10 seconds after the last command is given.
The diagnostic LED will blink in this mode. The safety
sensors (photo eyes) indicator LEDs will not be on. The
next operation command will return
the operator to normal operation.

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.

SAVE THESE INSTRUCTIONS.
