Important safety instructions

WARNING To avoid damage to property and potential injury follow all in­stallation and operation instructions in this manual. It is vital for the safety
of persons to follow all instructions. Save these instructions.

Keep remote controls away from children. Do not allow children to play with them.
Always supervise a moving gate. Keep people clear until the gate stops moving.
Use caution when releasing the gates for manual operation – the gate may move sud­denly.
Frequently examine the installation for signs of wear or damage. Do not use if repair or
adjustment is needed as the gate may cause injury.
Each month check that the drive stops or reverses when the gate contacts an obstruction.
Arrange for an Authorised Installer to adjust the opener if necessary since an incorrect
adjustment may be hazardous.
Each month check that any non-contact beam sensors function correctly by obstructing
them while the gate is moving. The gate should stop, or reverse.
Disconnect electric power to the gate opener before making any adjustments, repairs, or
removing any covers.

Manually opening the gate

You can release the gate from the opener. Remove the spring clip and pull the clevis pin
from the joint between the gate and the drive arm.
To reconnect the gate to the opener, move the drive arm back into position, replace the
pin and spring clip.

Operating from a remote
control or wireless switch

Press the button to stop a moving gate. The next press will move the gate in the opposite
direction.
From multiple buttons you can operate multiple openers or driveway lighting. Each opener
or controller must learn each button.
Replace the battery if the remote control or wireless switch doesn’t work, or if the green
indicator flashes when you push the button.

Learning additional remote
controls or wireless switches

You can learn up to 20 wireless controls into the opener. Contact Merlin if you need to
learn more than 20.
Each remote control or wireless wall switch must be learned by the opener.
There’s two possible ways to do this. Either:
Using a remote that already operates the gate; or
Opening up the controller and pressing a button.

Remote Transmitter Learning

This mode may not have been enabled by the installer. However, if it has, follow this
procedure:
Start with a transmitter that can already operate the gate.
Press both the North and the South buttons together, and hold them for three seconds.
Now press the button that normally operates the gate, hold it for one second.
Now the gate opener is ready to learn new button or new remote.
Press the new remote button and hold for one second.
Press the remote button again and hold for one second. This should complete the proc­ess.

Direct Transmitter Learning

There is a small red button marked LEARN on the receiver card, attached to the top of the
control board, inside the control box.

WARNING Take care when opening the cover to expose the controller and
receiver cards. If there is a transformer in the enclosure then there will be

mains voltages present on the primary (input) side.

Identify the button marked LEARN. Press and hold it for 2 seconds.
Press the remote control button that should operate the gate. Release after 1 second.
Press the remote control button again. Release after 1 second.
This remote control button should now operate the gate.

Deleting remote controls

This is only possible by directly accessing the controller board. To delete all the remote
controls from memory, press and hold the learn button on the receiver card for 11 sec­onds.

WARNING Take care when opening the cover to expose the controller
and receiver cards. If there is a transformer in the enclosure then there

will be mains voltages present on the primary (input) side.

Maintenance

Under normal operating conditions the only maintenance required is to keep the path of
the gates clear of debris and to spray around the controller occasionally to deter insects
from entering it.
However the gate and hinges may sustain damage or wear, presenting additional load to
the opener.
Frequently examine the installation for signs of wear or damage. Do not use if repair or
adjustment is needed as the gate may cause injury.
Each month check the sensitivity of your gate while it is closing and opening. Arrange for
an Authorised Installer to adjust if necessary since an incorrect adjustment may be haz­ardous.
Each month check that any non-contact beam sensors function correctly by obstructing
them while the gate is moving. The gate should stop, or reverse.
Ensure the beams are clear of any obstructions or dirt and ensure they are aligned to­wards each other.

Optional features

Your opener has the following features that may be enabled at any time by an Authorised
Installer. Additional Components and costs may apply. A registered electrician will be
required where mains power alterations are necessary.

Battery backup

A sealed lead-acid battery can be charged by mains power as a backup during power
cuts.

Keypad access

Keyless entry without carrying a remote control. Keypads can allow temporary PINs for
trades people or visitors.

Solenoid locking

For improved security electric locks can fitted. These will hold the gate firmly in the closed
position.

Auto-closing

Gates can close automatically after 10, 30 or 60 seconds.

NOTE Merlin recommends non-contact sensors to be fitted in conjunction with
automatic closing.

WARNING Gates should never be operated without supervision.

Although a force sensing safety system is present, it should not be relied upon as the
primary means of public safety. Always supervise a moving gate.

Non-contact safety beams

The closing movement of the gates can be reversed if an infra-red light beam is inter­rupted.
A beam set a few metres from the gate can reduce the risk of gates automatically closing
while a car drives through.

Driveway lighting controls

A small amount of low voltage lighting can be powered from the controller, or the control­ler can switch on any other powered lighting.
Lighting can operate from the remote control or from a timer that shuts off one minute
after the last gate operation

Troubleshooting

There are no user serviceable parts inside the opener. The power cord is not intended for
replacement by the user. Please refer to your dealer in the event that replacement is
required. Contact your dealer or Installer for any service requirements.

Gate will not open or close

The gate should operate smoothly, opening and closing without sticking or requiring un­due force. Release the gate from the opener and check that it is possible to move the
gate freely by hand through the full range of the opening.
There may be a power failure. Plug another appliance into the power point to check.
Opener may require service. If solar powered, the battery may not be fully recharging.
SOLUTION: Operate the gate manually. Phone an installer for service.

Gate will open but not close

If a sensor beam is fitted then it may be obstructed or misaligned. The gate mechanism
may have broken, presenting an abnormal load, causing the safety system to activate.
SOLUTION: Look for anything blocking the beam sensor. Is the beam aligned correctly?
Release the manual release and check the gate can be operated easily by hand. Have
your gate repaired or serviced if it is heavy to move by hand.

Transmitter range is less than normal

Your transmitter battery may be going flat. If you have an external antenna then the wire
may be damaged.

SOLUTION: Replace the transmitter battery. Phone for service if the antenna wire is
damaged

Transmitter doesn’t work some times

There may be occasional radio interference in your area. Your transmitter battery may be
going flat.
SOLUTION: Check for nearby baby monitors, remote control toys, cordless phones. Re­place the transmitter battery.

Radio interference

Gate remote controls are required to operate in shared radio frequency bands. Regula­tions permit other users to continuously operate higher powered devices such as baby
monitors or wireless headphones in these shared bands. These devices may cause radio
interference that reduces the performance of the remote control. Switch off interfering
devices if possible. Remote controls and receivers that operate on alternative frequencies
are available at additional cost.

Transmitter doesn’t work at all

Your transmitter battery may be flat. SOLUTION: Replace the transmitter battery.
