Important safety instructions for

installation

WARNING Incorrect installation can lead to severe injury. Follow all installation

instructions. Merlin Garage Openers Limited does not accept responsibility for

damage or injury resulting from installing this opener.

Prepare the gate for safe automation

Before installing the drive remove or disable any equipment, such as locks, that is not

needed for powered operation.

Check that the gate is in good mechanical condition and that it opens and closes properly.

Do not use force sensitivity adjustments to compensate for a binding or sticking gate.

Excessive force may damage the gate.

Avoid possible entrapment points

Ensure that entrapment between the driven part and the surrounding ﬁxed parts due to the

movement of the driven part is avoided.

Gaps are considered safe as follows (IEC60335-2-103): ﬁnger gaps above 25 mm; foot

gaps above 50 mm; head gaps above 300 mm; and whole body gaps above 500 mm.

Add over-ride switch if wicket gate is present

If a wicket gate is present in one of the gate leaves, it must be ﬁtted with a switch that

prevents the drive from operating when the wicket is open. (Connect a Normally Closed

switch to the STP and GND terminals of the controller board.)

Locate controls carefully

Install any ﬁxed control, wired or wireless, within sight of the gate but away from moving

parts and at a height of more than 1.5 m.

Fit non-contact safety beams

Where they are not already explicitly required to comply with regulations, Merlin strongly

recommends ﬁtting non-contact safety beam sensors.

Locate the entrapment warning sign correctly

After installing the gates, the included entrapment warning sign must be ﬁtted within sight

of anyone that may stand in the path of the moving gate.

Inspect and test the installation

After installation, ensure that the mechanism is properly adjusted and that and the

protection system and manual release function correctly.

Educate the owner

Before passing controls to the owner, alert them to the potential dangers, and routine

checks they’re required to perform.

Complete the commissioning check sheet

The commissioning check sheet at the end of this manual must be completed, signed

by the installer and client, and kept on record by the installing company. It contains a

declaration that all safety related procedures have been complied with.

Important safety instructions for

use

WARNING It is important for the safety of persons to follow all the instructions for

use. Save these instructions.

Controls are not a toy

Do not allow children to play with ﬁxed or remote controls.

Check the gate and drive for wear

Frequently examine the installation for imbalance and signs of wear or damage.

Check that the manual release functions correctly.

Do not use if repair or adjustment is necessary.

Test the safety system every month

Every month, test that the gates stop or reverse in response to an obstruction, and that

interrupting the beam of and photo-electric safety beam also causes the gate to stop or

reverse..

Do not use if repair or adjustment is necessary.

Disconnect power before maintenance

Always disconnect the power supply from the drive before cleaning or maintaining the

gate or drive. The drive or gate may operate unexpectedly due to other users with remote

controls, or due to automatic closing (if enabled).

Become familiar with the controls and manual release before use

Before using the gate and drive, locate the manual release and become familiar with its

operation. Note where the key is located, in the case of a power cut or any failure of the

drive or gate.

Manually opening the gate

You can release the gate from the

opener. Insert the key into the lock

on the underside of the opener. Turn

the key and pull the lever down. The

gate will be released from the drive.

To reconnect the gate to the drive, it

may be necessary to move the gate

back to the same position as where

it was before unlocking.

Maintenance

In an area where ant or insect infestation is likely, regularly spray around the opener and

any electrical installation with insecticide. In normal conditions it is not expected that any

additional lubrication or service is required. Keep the path of the gate free from debris and

foliage.

The gate and its moving parts 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.

Insert key, turn

and pull the

lever down to

release the drive.

Learning wireless controls

1. Press P2/RADIO until the red LED is lit.

2. If the wireless remote controls are required to only operate Pedestrian Access

mode, install the CH-RADIO jumper over its pins. If the wireless remote controls

are for full access, remove the CH-RADIO jumper.

3. Press the desired button for 3 seconds once on each wireless control that is

required to operate the gate.

NOTE The red LED will blink during learning. The controller is ready for another wireless

control when the red LED is steadily lit.

4. Press P2/RADIO to exit learning mode.

NOTE The learning procedure will time out after 10 seconds of no activity.

Deleting all wireless controls

1. Press and hold the P2/RADIO button until the red LED blinks rapidly.

2. Release the P2/RADIO button.

3. Within 6 seconds, press the P2/RADIO button again to conﬁrm.

Deletion is indicated by the red LED blinking faster.

Deleting selected wireless

controls

The optional accessory GT/SYSTEM hand-held controller is required. Contact Merlin for

details.

Site requirements

Check that the temperature range marked on the drive is suitable for the location. Do not

install the drive where ambient temperatures will exceed the ratings.

Gate

This opener is designed for residential swing gates

up to 2 metres wide and less than 140 kg.

Using a spring balance at a point approximately 1

metre from the hinge, check that less than 8 kg

force (80 N) is required to manually move the gate

through its full range of movement, with the gate

disconnected from the drive.

The gate should operate smoothly, opening and

closing without sticking. Hinges should not have

excessive play or friction. Check the mounting

points and hinges for strength and stiffness.

Reinforce if necessary.

Gate posts

There should not be any visible ﬂexing of the mounting points under load.

Level and square the gate

The gate hinge pivot points should be perfectly parallel to a plumb line. When closed, the

gate leaves should line up evenly and not bind against each other. The leaves should not

be damaged or bent.

Gate stops

It is recommended that any of the following are used:

• Overlapping gate leaves

• A tag on one gate

• Gate-stops at the limit of each leaf’s travel

Power supply

Mains powered

If the opener is to be mains-powered, then the 3-pin power plug should be shielded from

the effects of weather. The product is tested as a unit for electrical safety compliance

and if the plug is cut off for hard-wiring, then the electrical safety of the unit becomes the

responsibility of the installing electrician. An isolating switch is recommended, but all mains

wiring should be in accordance with local regulations.

Solar Powered

Contact Merlin for the correct battery and solar panel. The size of these depends on: the

duty cycle of the gates; the hours of sunlight; and the number and type of accessories

ﬁtted.

8 kg force

1 metre

Battery powered with trickle charging

Due to the high cost of long runs of heavy cable, it may be more economic in some

installations to operate the gates from a larger battery, which is charged from a remotely

located trickle charger.

For example, a 16V ac 500 mA plug pack can be located at the house, with appropriate

wiring to the gate, controller, and battery some distance away. Due to varying gate loads

and duty cycles for each installation, this is a guide only.

Wiring

All wiring must be arranged to prevent water entering the controller enclosure.

Do not wire mains voltages and low voltage control wires in the same conduit.

Low voltage cable sizes

Voltage will drop along low voltage cables over long distances. It is recommended to use

cable with conductors of the following minimum cross sectional areas. The table lists

lengths for twin-core cable, from the supply to the load.

For an optional solar panel, consider the total length from the panel to the controller board,

through to the battery. Follow the table for minimum recommended conductor sizes for

given lengths for each power option.

Installation

Mounting brackets to the gate posts

There should not be any visible ﬂexing of the mounting points under load.

To spread the load, all mounting holes should be used.

Use fasteners of at least 8 mm diameter x 75 mm length.

Height

Mount the centre line of the bracket either 10 or 5 mm higher than the centre line of the

gate bracket, depending on whether two or three pieces of post bracket are used. This is

to maintain a level actuator.

If the conditions are very dusty, for example around an unsealed driveway, do not mount

the actuators lower than 400 mm above the ground. This is to reduce the likelihood of dust

entering the screw mechanism.

Position relative to gate pivot

Refer to the diagram below for the typical co-ordinates of A and B.

Some guidelines for an easy installation are:

A + B < 340 for up to 90 degrees opening

A + B < 320 for up to 100 degrees opening

A + B < 310 for up to 110 degrees opening

Increase A for a slower but ﬁrmer stop open

Increase B for a slower but ﬁrmer stop closed

Optimum dimensions are:

opening angle A B P(max)

90º 190 150 160

100º 160 160 130

110º 130 180 100

Gate pivot offset from mounting face

The dimension P on the diagram must be:

less than 160 mm for 90 degrees of opening angle;

less than 130 mm for 100 degrees; and

less than 100 mm for 110 degrees.

Typical installations: in-swinging gates

Typical installation: out-swinging gate

IMPORTANT For all installations the angle between the drive arm and the gate should

always be convergent. If at any position the arm and gate are divergent, there will be

excessive stress placed on the gate components.
