4 Trickle charging with battery backup Due to the high cost of long runs of heavy cable, it may be more economic in some instal- lations to operate the gates from an optional backup battery, which is charged from a re- motely located trickle charger. For example, a 12V 500 mA plug pack can be located at the house, with only light gauge wiring to the gate, controller, and battery some distance away. Due to varying gate loads and duty cycles ...

5 Installation Mounting the operators 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 10 mm diameter x 75 mm length. The gate post bracket can be assembled in many different ways to provide a range of possible mounting positions. It may be necessary to cut or re-drill in some circumstances. Attaching the gate bracke ...

6 90O in-swinging gates Note the 130 mm and 160 mm offsets from the diagram. The gate should be no more than 70 mm in front of the rear of the post, to prevent the actuator from touching the corner of the post. 1100 in-swinging gates Note the rearward offset reduces to 100 mm. The side offset stays at 160 mm. The gate should be no more than 70 mm in front of the rear of the post. Out-swinging gate Note the 130 mm and 160 mm offsets from th ...

7 Connecting the board wiring NOTE When powering any accessories from the board, (for example: gate latches, additional receivers, keypads, PE beams) ensure the power supply has adequate capacity. Measure the voltage at DC IN under full motor load. If it falls below 9 V dc then the board, receiver, and some accessories, may not function correctly. In this instance, remove accessories, upgrade the power supply, or provide additional power s ...

8 Connecting the motor wiring Motor 1 is the left hand motor when facing out of the driveway. If Motor 1 is on the right hand side, reverse the polarity of the motor wires. If a single opener is fitted, use the Motor 1 terminals. If a single opener is fitted on the right hand side, reverse the polarity of the motor wires. If a motor pushes a gate outwards, reverse the polarity of the motor wires. Setting the limits The fully extended limit ...

9 Board adjustments Sensitivity Allow for the effect of weather. Wind or water will make the gates more difficult to move. If the sensitivity is set to react to extremely light obstructions then the gates may fail to open or close fully. After adjustment, check that the force on an obstruction at the far end of the gate leaf does not exceed 150N (15 kg). Use a spring balance. Travel time Allow 3 – 5 seconds more than the normal travel ti ...

10 Receiver setup Mode jumper This jumper must be removed. If it is not removed then the remote will only operate the gate once for every two button presses. This jumper enables the latching output on the receiver card. Learning remotes The receiver can learn up to 20 remotes. After 20 remotes, the 20th will be overwritten. Only one button per remote can operate the receiver. To learn a remote, press and hold the LEARN button until the rec ...

11 Setting up the board NOTE Reverse motor wires if open and close LEDs don't match gate travel. MANUAL/ AUTOCLOSE Jumper (safety beams must be fitted) Motor 1 open delay (max = clockwise) 2 – 5 sec MODE jumper (must be removed) Motor 1 Sensitivity (max = clockwise) Test button (press to operate gate) Motor 2 Sensitivity (max = clockwise) MU / NORM jumper (MU = every command opens the gate NORM = open / stop / close) (Requires Autoclose) ...

12 Optional extras Keypad The Merlin M840 keypad can accept a hardwired power supply to overcome the need for replacement batteries. See the keypad documentation for full details, but any supply with 50 mA at 10 – 24 V ac or dc is suitable. Control of the gate opener is wireless using high security code-hopping RF. Solenoid lock (latch) See the lock's documentation for installation details. Merlin can supply either horizontal or vertical ...

13 Troubleshooting Remote controls will not function while gate is moving The total load on the power supply may be exceeding its capacity. Measure the voltage into the board. If less than 9V dc when the motors are under load, then a higher capacity power supply must be fitted, or some accessories removed, or separate power supplies provided for the accessories. Gate will not open or close The gate should operate smoothly, opening and clos ...

14 Maintenance In an area where ant or insect infestation is likely, regularly spray around the opener and any electrical installation with insecticide. Occasionally wipe the ram clean and spray it with a silicone lubricant. Keep the path of the gate free from debris and foliage.
