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. Using the provided
spanner, loosen the large bolt on
the underside of the opener. This
bolt attaches the primary arm to
the output shaft of the opener.
Undo the bolt by turning the
spanner clockwise as viewed
from above.
Do not fully remove the bolt.
Undo it until the primary arm falls
10 – 12 mm, enough for the arm
to disengage from the shaft.
To reconnect the gate to the
opener, lift the arm while moving
the gate until the arm engages
on the shaft. Retighten the large
bolt.
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.

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 3 metres wide and less
than 230 kg.
Using a spring balance, check that less
than 15 kg force (150 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.
Battery powered with trickle charging
Due to the high cost of long runs of heavy cable, it may be more economic in some
maximum 15 kg force

7
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.

Master and slave operators
The Master operator has the controller board, transformer and optional back-up battery
inside it. Locate it on the side of the gate nearer to the power supply. The Slave operator
connects to the master by a two-core conductor carrying 12V.

Installation clearances
Standard side-room vs. restricted side-room
The standard side room requirement is 550 mm. If
less than this is available, it is possible to shorten
the secondary arm (the one that attaches to the
gate). Do not shorten it to less than 350 mm.
Take care that the attachment point between the
gate and the secondary arm does not foul on the
output shaft. A certain amount of trial and error
is involved in selecting the optimum position for
the gate bracket. See the following sketches as
a guide.
Ensure the angle between the primary and secondary arms is always greater than 40
degrees. The gate hinge should be no more than 200 mm forward of the mounting face
of the drive.
In the example shown, reducing the length of the secondary arm reduces side room
considerably. Note however that the leverage applied by the opener on the gate can
change dramatically in the last part of the opening cycle.
Ensuring the angle between the arms is always greater than 40 degrees is recommended.
When the arms are fully extended, the angle between them should not be more than 175
degrees.

Side mounting
This is useful where the gate must open
further than 90 degrees, or where the gate
must open outwards. Contact Merlin for side
mounting covers.
Out-swinging gates
This also requires side-mounting covers. It
may be necessary to fabricate longer primary
arms for some installations.
Mounting the operators to the gate posts
Mount the opener 50 mm from the inside edge of the gate post. Use fasteners of at least
10 mm diameter x 75 mm length. To spread the load, all bracket mounting holes should
be used.
NOTE The top face of the gate bracket aligns with
the centres of the bottom mounting holes of the
opener.
Attaching the gate bracket to the
leaf
The gate bracket connects the secondary arm to
the gate leaf. Position it after following the diagrams
above. The primary and secondary arms must never
be less than 5 degrees off a straight line from each
other. Choose a point which is less likely to deflect
under load. If necessary, weld support around the
area where the bracket must be positioned..

transformer input
Can accept 12 or 24 V ac, max 100 VA, max 10 A.
NOTE The transformer must have sufficient capacity to maintain motor voltage above 10
V (or above 20V for 24V systems).
battery input
A 12V 1.2 Ah sealed back-up battery is recommended, and should result in sufficient
capacity for at least five full operations in the first 24 hours of any mains supply failure.
motor 1 (MOT1) and motor 2 (MOT2) outputs
Motor 1 is the one which opens first; motor 2 is the one which closes first. Often Motor
1 is on the left hand side when looking out the driveway. The delay between motor 1 and
motor 2 operation is set by the trimmer marked – DEL +. If the motor direction is reversed,
swap the polarity of the connection wires.
flashing warning lamp output (LAMP)
The outputs are set up for a 2 W flashing lamp, at either 12 or 24 V dc, depending on the
board’s supply voltage. The board supplies power to the lamp, but it is a continuous supply,
so the lamp must have a flashing circuit built in. The output supplies power to the lamp
from 1 second prior to opening, until fully open; and from two seconds prior to closing, until
fully closed. If the board is running only from battery backup, then the lamp will only flash
for the first four seconds of operation.
courtesy lamp (EXT. LAMP) / electric lock (EL. LOCK)
module output
To connect an electric lock or a courtesy lamp, it is necessary to fit an optional expansion
module. Only one module can be fitted. This must be connected with the three wires
arranged as red-grey-black from left to right.
The ELU Electric Lock Unit module can accept a lock rated at up to 12V 15W. When a
lock is fitted, it is recommended to fit the STRIKE jumper over both its pins. This enables
a short delay before opening, to allow the lock to release before the gate leaf moves. The
LCU Lamp Control Unit module can accept a lamp rated at up to 12V 15W.
tx photocell power out (TXF), photocell signal in (PHO)
Photocells should have NC (normally closed) contacts when there is no obstruction. Fit a
jumper wire between the signal input terminal and ground if no photocells are fitted. The
maximum total accessory power load allowed is 150 mA. The combined consumption on
the TXF and VA terminals must not exceed this limit. Photocells are part of this total load.
NOTE 1 If the TEST jumper is fitted, the unit performs a function test on the photocells
before each operation. This adds a 200ms delay before every operation. The transmitting
photocell must be powered from the TXF output. Photocells must have NO (normally open)
contacts when the power is off.
NOTE 2 If the PAU trimmer is set to fully anticlockwise and the photocell beam has been

13
interrupted, then the gates will close 1 second after the beam is cleared.
NOTE 3 The default behaviour of the gates is to react immediately when the beam is
interrupted. Professional Setup Step 12 allows this to be changed. Gates can be made to
stop in response to an obstruction, and then only react after the obstruction is removed.
accessory power output (VA)
The maximum total accessory power load allowed is 150 mA. Accessories in excess of this
limit must be powered directly from the battery.
NOTE The transmitting photocell must be powered from the TXF output if the TEST
jumper is fitted.
start signal input (STR)
This input is NO (Normally Open). When it is momentarily closed to ground the opener will
start. If the gate is already moving then momentarily closing the start input to ground will
stop the movement.
Connect a keyed switch or exit request button to this input. While this input is closed to
ground, any auto-closing function is disabled. This input can be connected to a timer to
force the gates open during certain periods of time.
stop signal input (STP)
The Stop input is NC (Normally Closed). Fit a jumper if no switch is used. When this terminal
is not connected to ground, the gate will not operate – it will not open or close until the
terminal is reconnected to ground, and it will only restart once a command is sent through
the Start input, or through a learned wireless remote control. If the gate is moving when this
terminal is momentarily disconnected from ground then the gate will stop moving until the
connection is re-established, and then only when another Start command is received.
pedestrian access signal input (PED)
This NO (Normally Open) input can connect to safety devices such as pressure edges, or
to a switch that enables one wing to open. Activating a safety device will prevent movement
from fully open or fully closed, and will cause movement to reverse while opening. Safety
devices connected to PED have no effect during closing. A switch connected to the PED
terminal will cause only the M1 leaf to open. The factory default setting opens the M1
leaf for 5 seconds, and this can be over-ridden using the Professional Setup routine. The
leaf will close automatically if auto-close is enabled; otherwise another manual command
is required. Normal opening and closing commands take priority over Pedestrian Access
commands. It is also possible to activate Pedestrian Access using a wireless remote control
that has been learned while the CH-RADIO jumper is fitted.
antenna input (ANT)
The centre wire of a 50-ohm co-axial cable should connect to this terminal. An antenna
of 175mm is recommended. Connect the outer braid of the co-axial cable to the ground
terminal. A ground plane greatly improves an antenna’s performance. It should connect
to the end of the co-axial cable’s braided screen. An alternative is to mount the antenna
through a metal plate that is at least as large as the ground plane’s length.

Set the application mode
WARNING Follow these steps. This setting is an integral part of the safety system. The
controller must be set differently for each motor type and load. Application mode sets the
maximum allowable motor current. In combination with the FOR setting (motor voltage),
and OBS setting (time before reversing from an obstruction), a safe threshold for the
energy applied to an obstruction is set.
Press RESET and observe the red LED. There must be two flashes.
• One flash for Merlin G815D linear actuators
• Two flashes for Merlin G915D/G950 harmonic arm actuators
If there are not two flashes, the application mode must be changed:
1. Press P2/RADIO until the red LED is lit
2. Press P1/SET and observe the number of flashes of the yellow LED. 1 flash for
linear actuators; 2 flashes for harmonic actuators
3. Press P1/SET again until two flashes of the yellow LED occurs
4. Press P2/RADIO to exit programming
Learn a remote control
A remote control is useful for operating the controller during setup.
Press and hold P2/RADIO until the red LED is lit. Press the main button on the remote
control. Wait 10 seconds to exit learning mode.
Install the CH-RADIO jumper. Press and hold P2/RADIO until the red LED is lit. Press the
second button on the remote control. Wait 10 seconds to exit learning mode. Remove the
CH-RADIO jumper.
Now the main remote button will act as P1, and the second button act as P2.
Set motor limit cams
The motors on each drive must be operated in order to set the limit-travel switches. To
operate the drive motors, use the remote control that has just been learned .
Do not fully fit the primary arm to the drive before setting the limits. Leave the bolt loose
so that the drive does not engage with the arm. This will prevent possible injury or damage
before the limits are correctly set.
Close the gates
Operate the motors until their output shafts are in the correct position to engage with their
primary arms of closed gates. Loosen the limit cam cap-screw.
Left hand motor: rotate the bottom cam anticlockwise until it actuates the switch.
Right hand motor: rotate the top cam clockwise until it actuates the switch.
Retighten the limit cam cap-screw.
Open the gates
Operate the motors until their output shafts are in the correct position to engage with their
primary arms. Loosen the limit cam cap-screw.

Left hand motor: rotate the top cam clockwise until it actuates the switch.
Right hand motor: rotate the bottom cam anticlockwise until it actuates the switch.
Retighten the limit cam cap-screw.
Easy setup
Easy setup must be performed to set the opening and closing travel times.
NOTE Easy setup only sets the limits and force/speed, and is fully automated; professional
setup also offers slow-stopping and pedestrian access, but is not fully automated. It is an
automated procedure that sets the gate leaf travel times based on the detection of the
limits of travel. Gate stops or limit switches must be used. Gate stops must be positioned
such that the gates rest firmly against them at each limit of travel.
CAUTION During this procedure the gates must be attended. Movement can be stopped
at any point by pressing the RESET button. The gates must be in the midway position
before starting this procedure.
To initiate the procedure, press RESET, press P1/SET for 1 second while the yellow LED
is flashing. The following steps are performed automatically:
1. Detects whether one motor or two is fitted
2. Sets pedestrian opening on M1 leaf to half way
3. Checks for presence of photocells (or a jumper) on PHO terminal; e-stop (or a
jumper) on STP terminal
4. Begins to open the M1 leaf.
5. Note If the M2 leaf moves first, or if the leaf begins to close first, press RESET to
stop the movement and then reverse the motor wiring accordingly. Start this setup
procedure again.
6. Begins to open M2 leaf 1 second after the M1 leaf.
7. After 3 seconds of opening, gates stop moving.
8. Closes the M2 leaf fully, closes the M1 leaf fully, stopping hard against the closed
stops (if fitted) or stopping using a limit switch.
NOTE Force detection is used to sense the limit position. Do not set the force/speed/
voltage control (FOR) to maximum before this operation.
9. Opens the M1 and M2 leaves fully, stopping hard against the open-stops (if fitted)
or stopping using a limit switch.
NOTE Force detection is used to sense the limit position. Do not set the force/speed/
voltage control (FOR) to maximum before this operation.
10. Pauses 3 seconds at fully open.
11. Closes fully, slowing down to around 1/3 speed, after 90% of the travel time.
In summary the procedure is: open 3 seconds, close fully, open fully, wait 3 seconds, close
fully.

Controls
IMPORTANT If the force/speed/voltage setting (+FOR-) is adjusted then it is necessary
to perform either Easy Setup or Professional Setup again because the travel times will
vary. Failure to do this risks causing damage to the gates or gate stops.
After every trimmer adjustment press RESET to confirm the change. Wait for the LED to
stop flashing.
reset button (RESET)
Pressing RESET has the same effect as interrupting the power supply. It will stop the
movement of the gates. The yellow LED will flash for five seconds and then the board will
be ready to operate. No memory settings are altered when RESET is pressed. No learned
wireless transmitters are removed from memory.

learn wireless pedestrian access jumper (CH-RADIO)
Place this jumper over the pins when you want to learn wireless remotes for Pedestrian
Access mode.
force/speed/voltage setting trimmer (+ FOR -)
NOTE Press RESET after adjusting the trimmer.
The energy transferred to an obstruction is determined by the motor power, and the time
that the power is applied to the obstruction. Motor power is determined by the maximum
voltage and maximum current. This FOR setting alters the motor voltage. The Application
Mode (page 7) alters the maximum allowable motor current. The OBS setting alters the
time that power is applied to an obstruction. So safety is determined by a combination of
the settings for FOR, OBS, and Application Mode.
Turn FOR clockwise to increase the voltage that is applied to the motors.
• Full clockwise: maximum voltage (less sensitive)
• Full anti-clockwise: minimum voltage, approximately 50% of the maximum (more
sensitive)
NOTE Voltage affects the speed of the motor. After any adjustment to FOR, either the
Easy Setup or the Professional Setup procedure must be completed to set the operating
time correctly.
auto-close pause setting trimmer (+ PAU -)
WARNING Photocell sensor beams must be fitted when using auto-close.
This trimmer determines the length of time that the gates pause before auto-closing.
• Full clockwise: auto-closing is disabled (that is, there is an unlimited pause when
open)
• Full anti-clockwise: pause open for 15 seconds, then auto-close (unless a photocell
is fitted)
• Other positions: adjust for pause times of between 3 seconds and 60 seconds
In auto-closing mode, any command to open or close will cause the following behaviour:
• while opening, commands are ignored;

G950 May 05
18
• while closing, commands will cause the gate to start to open;
• while paused open, commands will not close or open, but will restart the pause
timer
NOTE If a photocell is connected to the PHO terminal then the response to interruptions
of the beam will vary depending on the setting of the PAU control, and depending on the
choice of option in professional setup:
• PAU full anti-clockwise:
Gate opening - nothing happens if the beam is interrupted
Gate paused open for 15 seconds - if beam is interrupted nothing happens until
the interruption is removed; 1 second after the interruption is removed the gate
will close
Gate closing - if the beam is interrupted, then open fully, pause for 1 second, and
begin to close
• PAU in all other positions:
Gate opening – nothing happens if the beam is interrupted
Gate closing - if the beam is interrupted, then open fully
NOTE Press RESET after adjusting the trimmer.
photocell option setting - see Professional Setup.
If the ‘stop when interrupted, move when clear’ option is enabled in Step 12 of
Professional Setup, the above behaviours will be modified accordingly:
• PAU full anti-clockwise:
Gate opening - stop if the beam is interrupted, continue opening when the beam
is clear, once open the gates will autoclose after 1 second (not 15 seconds as
usual)
Gate paused open for 15 seconds - if beam is interrupted nothing happens until
the interruption is removed; 1 second after the interruption is removed the gate
will close
Gate closing – stop if the beam is interrupted, then open fully when the beam is
clear, pause for 1 second, and begin to close
• PAU in all other positions:
Gate opening – stop if the beam is interrupted, continue opening when the beam
is clear
Gate closing – stop if the beam is interrupted, then open fully when the beam is
clear
obstruction sensing trimmer (+ OBS -)
Turn this clockwise to make the gates less sensitive, that is to increase the time
delay that occurs before reacting to the detection of an obstacle. Turn anti-
clockwise to make the gates more sensitive to obstructions.
• Full clockwise: maximum time delay of 2.5 seconds before reversing (less
sensitive)
• Full anti-clockwise: minimum time delay of 0.1 seconds before reversing (more
sensitive)
• Other positions: adjust for delay times of between 0.1 and 2.5 seconds

NOTE If an obstruction is detected when opening, the M2 leaf will always close fully
before the M1 leaf.
motor leaf delay trimmer (+ DEL -)
NOTE Press RESET after adjusting the trimmer.
Turn this clockwise to increase the time delay that occurs between the start of movement
of the M1 leaf and the start of movement of the M2 leaf. This is essential when using gate
tabs or overlapping leaves. To prevent clashing of the gate leaves, increase the motor leaf
delay.
• Full clockwise: maximum time delay of 30 seconds between M1 and M2 moving
• Full anti-clockwise: minimum time delay of 3 seconds
• Other positions: adjust for delay times of between 3 and 30 seconds
enable lock strike delay jumper (STRIKE)
If the ELU module is connected, along with an electric lock, then this jumper may be required.
When the STRIKE jumper is connected across its two pins, then an open command to a
fully closed gate will be delayed by 1 second to allow time for a solenoid lock to release.
enable testing of safety devices jumper (TEST)
Connecting the TEST jumper across its two pins will cause the controller to verify the
operation of the photocell and / or safety edge before every operation. This test switches
off the power to the safety device and verifies that the device’s output changes state.
Therefore the safety device must be capable of being tested in this way. A 200 ms delay
is created before every movement. The TEST jumper must be removed if safety devices
are not fitted.

Professional setup
Professional setup is a semi-automated procedure, similar to Easy Setup, but with the
following differences:
• Initiate by pressing P2/RADIO instead of P1/SET
• The installer must intervene to manually operate the gates
• The installer may set a desired slow-down position, if not there will be no slow-
down
• The installer must intervene to manually close the gates
• The installer may change the behaviour in response to photocells
• If pedestrian opening is required, then the installer must set it, otherwise pedestrian
opening time is zero
NOTE This procedure sets the gate leaf travel times based on the detection of the limits
of travel. Gate stops or limit switches must be used. Gate stops must be positioned such
that the gates rest firmly against them at each limit of travel.
CAUTION During this procedure the gates must be attended. Movement can be stopped
at any point by pressing the RESET button. The gates must be in the midway position
before starting this procedure.
To initiate the procedure, press RESET, press P2/RADIO for 1 second while the yellow
LED is flashing.
NOTE It may be more convenient to use a transmitter to control the process, than to press
the P1/SET and P2/RADIO buttons on the controller board. If so, learn one button for P1
(learn the button with the CH-RADIO jumper removed), and one button for P2 (learn the
button with the CH-RADIO jumper fitted).
The following steps are performed automatically:
1. Detects whether one motor or two is fitted
2. Checks for presence of photocells (or a jumper) on PHO terminal; e-stop (or a
jumper) on STP terminal
3. Begins to open the M1 leaf, with a force set by the FOR trimmer.
NOTE If the M2 leaf moves first, or if the leaf begins to close first, press RESET to stop
the movement and then reverse the motor wiring accordingly. Start this setup procedure
again.
4. Begins to open M2 leaf 1 second after the M1 leaf.
5. After 3 seconds of opening, gates stop moving.
6. Closes the M2 leaf fully, closes the M1 leaf fully, stopping hard against the closed
stops (if fitted) or stopping using a limit switch.
NOTE Force detection is used to sense the limit position. Do not set the force control
(FOR) to maximum before this operation.
The following steps must be performed by the installer:
7. Press P1/SET to begin opening the M1 and M2 leaves
8. Press P1/SET at the time where M1 slow down to 1/3 speed is required
9. Press P2/RADIO at the time where M2 slow down to 1/3 speed is required
10. The M1 and M2 leaves will continue to open fully, stopping hard against the open
