Installation Overview

Installation of the Opener

Caution:

Be sure that the opener is installed in a level and paralleled position and is properly secured.
Improper installation could result in property damage, severe injury, and/or death. Before starting the installation, ensure that there is no point of friction during the entire movement of the gate and there is no danger of derailment.

Ensure that the Warning Signs are present
Necessary Tools: The following tools may be necessary to install the Gate opener. You will need screwdrivers, an electric drill, wire cutters, and a wire stripper, a socket set,
and possibly access to a welder. When installing the opener, you should build a concrete pad to support the base plate of the opener in order to maintain proper stability.
The installation proceeds are as follows:
1. Dig a hole for a concrete pad which should be approximately 60 x 32 x 35cm (24 〞x 13〞x 14 〞). It may protrude 10 cm (4”) above ground and 25 cm (10”) in depth underground. Increase the pad height if necessary to protect the system from flooding, heavy snow, etc.
2. Prepare one or more conduits for the electrical cables before pouring concrete. Remember that cable conduits have to pass through the hole in the base plate.
3. Pour the concrete and before it starts to harden, check that it is parallel to the gate leaf and perfectly level.
4. The four anchor bolts must be set into the concrete when it is poured, make sure the position of the anchor bolts was placed according to the position of mounting holes on the base plate before the concrete becomes hardened.
5. Mount the base plate to the concrete Pad. It’s only a temporary installation. The further adjustment will be required when installing the chain.
6. Mount the chain box to the base plate by using screws and washers, don’t make the four screws too tight.

Manual Operation

The opener should be put in the manual (emergency release) position before fitting the chain and installing the opener and limit switch. The process is as follows:

Take of the rubber stopple.
Insert the Release Key（provided ）and turn it counter-clockwise 180° to disengage the clutch between the gear shaft and power output. Now the opener is in manual operation.

Installation of chain and chain brackets

1. Chain Brackets

Please refer to the below chain brackets figure, which shows the “U” bolt, “L” bracket, and chain bolt.
Use the “U” bolts (square or round) to attach the chain brackets to the gate frame.
If Both the square bolts and round bolts are not fit the gate frame, use the appropriate bolts to attach the chain brackets to the gate frame.

2. How to install the chain

Place the chain around the top of the idler
wheels and under the drive sprocket in chain box.
Connect a chain bolt to one end of the chain from the chain box by using the master link. Then insert the chain bolt to the L bracket and fix them each other with washers and nuts temporarily. (Nuts will be further adjusted for a proper chain tension later)
Connect the second chain bolt with another end of the chain from the chain box, then attach the bolt to the L bracket on the opposite end of the gate using the washers and nuts.
Make sure that the chain is lined up exactly with the position where the chain is on the chain idler wheel.
Set appropriated chain tension by adjusting two chain bolts of both ends. Cut the unwanted length of the chain if necessary.
Fix the base plate by tightening the washers and nuts.
Insert the opener shaft into the drive sprocket of the chain box and mount the opener by tightening the bolts and washers.
Fix the chain box by tightening the four lax screws.

Thoroughly fasten the four nuts as well as spring washers onto anchor bolts tightly, enabling the opener is firmly secured on the concrete pad during the wholgate travel.
3. Check the position of the opener and chain brackets
1. The chain brackets must be mounted to the same height as the chain on the idler wheels.
2. The opener must be parallel to the gate.
3. Make sure there is 1” distance at least between the chain box and the gate after you position the base plate.

Installation of the Magnets
Before installing the limit switch, make sure the gate opener is put in manual operation. (the clutch connected with gear shaft is disengaged) and the mains power supply is disconnected
Position the two Magnet Components approximately on the gate and move the gate by hand to fix them in place. Fit magnets bracket
Push the gate fully closed by hand. Locate and install the magnet bracket so that the opener will stop at the desired close position when the close limit switch approaches it.
Push the gate fully open by hand. Locate and install the magnet bracket so that the opener will stop at the desired open position when the open limit switch approaches it.
The magnet component with the N pole outside must be installed on the left side and the magnet component with the S pole outside must be installed on the right side from the view inside of the property.
Ensure the magnet center aligns with the marked line above!
The magnets should be 20~30mm (0.8-1.2”) away from the Limit Switch Box. If it is too near or too far, the switches will fail to work. Adjust the position of the magnets until the positions of the opening and closing meet the requirement.
Warning: Improper magnets installation may cause the gate to crash into the end barrier which is very dangerous!
Connection of the Power Supply
WARNING: NEVER connect the gate opener to the power outlet before all the installations have been done.
NOTE:

If batteries are chosen as the power source, a Marine or Automotive Type Battery is required. The batteries should be a waterproof type or be placed in waterproof circumstances.
2 PCS 12VDC batteries can be connected in series to function as 24VDC. The following diagram shows how to connect 2 PCS batteries in series.
Please note that the wire connection of the power supply system is very important. An incorrect wire connection will damage the control board.

Power Mode 1. Only use the AC electricity as the power source
The power supply cord should be at least 3×0.75mm 2 (3C×18AWG). Connect the live wire, neutral wire, and earth wire to the “L”, “N” and “PE” terminals respectively.
NOTE: The power supply cord is not included in the package.
Power Mode 2. By AC electricity and backup batteries, only use the AC electricity to charge the batteries
If the AC electricity failure happens rarely (less than 8 hours per day), then you can use minimum 5Ah
2*12VDC batteries as backup power source in case of
AC power failure. In this situation, you can connect the
AC electricity following the “Power Mode 1” and the batteries to the BAT terminal of the control board directly as the below wiring diagram.

Power Mode 3. Only use the batteries as the power source, only use the solar panel to charge the batteries
If AC electricity is not available, then you can choose the batteries as the power source and use the solar panel to charge the batteries. The capacity of the batteries should be at least 12Ah and the power of the solar panel should be at least 30W in this situation. The gate opener can run for 10 cycles per day without connecting any other accessories except the pushbutton & warning light if the local average sunshine time is more than 6 hours per day. The power of the solar panel and the capacity of the batteries should be larger if the local average sunshine time is less than 6 hours per day or use one of the accessories (photocell, external receiver, exit wand, and keypad). Please provide us with more details of the local sunshine condition and accessories needs so that we can calculate the configuration of the solar panel and the batteries. Please connect the batteries & the solar panels & solar controller refer to the following wiring diagram.

Power Mode 4. By AC electricity and backup batteries, use the AC electricity and the solar panel to charge the batteries at the same time
If the AC electricity failure happens frequently and lasts for a long time (maybe 4-5 days one time), then you can charge the batteries with the AC electricity and the solar panel at the same time. The capacity of the batteries should be at least 7Ah and the power of the solar panel should be at least 20W in this situation. You can connect the AC electricity following the “Power Mode 1” and the batteries & the solar panels & solar controller refer to the following wiring diagram.

The BLUE wire of the wired keypad should be connected to the “16” terminal.
The PURPLE wire of the wired keypad should be connected to the “17” terminal.
NOTE: Using of the photocell, exit wand, keypad, and external receiver would cause the battery to be exhausted quickly. A big capacity of batteries and big power of solar panels is required if you want to use any one of them (If the batteries and solar panel are used as the main power supply).

Setting of the Control Board

WARNING: Ensure the gate opener is Power Off when you make any adjustment to the gate opener. Keep away from the path of the gate during you set the gate opener system in case of the unexpected gate moving. Carefully adjust the DIP switches to avoid the risk of machine damage and injury or death. Always ask the help of a professional technician /electrician if you have any questions.
1. DIP Switches
The DIP switches are used to set the running time of the motor in Midway mode, fine adjust the soft stop period of the motor, auto close time of the gate opener, and fast change the open/close direction which is determined by the position of the gate opener installed.
DIP Switch #1–#2: Running time of the motor in Midway
Mode
DIP Switch #1: ON – 2 Seconds OFF – 0
DIP Switch #2: ON – 4 Seconds OFF – 0
NOTE: The midway mode function would be disabled if both DIP switches are turned off. The factory default setting is disabled. The midway mode could be activated by pressing button B of the remote control when the gate is in the full closed position.

DIP Switch #3–#5: Fine adjust the soft stop period of the motor
DIP Switch #3: ON – 1 Second OFF – 0
DIP Switch #4: ON – 2 Seconds OFF – 0
DIP Switch #5: ON – 3 Seconds OFF – 0
NOTE: Every time you restart the gate opener after power off, you should use the access control device (such as remote, push button and etc.) to operate the gate opener to run for a complete opening cycle and a complete closing cycle to get the full opening time and the full closing time. You would achieve the soft stop in your next opening/closing cycle. Factory default soft stop time is 3 Seconds. You can turn the DIP switches on/off to fine adjust the soft stop time to meet your actual needs.

DIP Switch #6–#7: Auto close time of the gate opener
DIP Switch #6: ON – 30 Seconds OFF – 0
DIP Switch #7: ON – 60 Seconds OFF – 0
NOTE: The auto close function would be disabled if both DIP switches are turned to off (factory default setting).

Important Note: When the auto close function is enabled, the photocell sensor is highly recommended to be installed with the gate opener for safety.
DIP Switch #8: Left/Right Open

Potentiometers
Potentiometer A is used to adjust the close stall force of the gate operator. Turn clockwise to increase the stall force, and turn it counter- clockwise to decrease the stall force.
Potentiometer B is used to adjust the open stall force of the gate operator. Turn clockwise to increase the stall force, and turn it counter- clockwise to decrease the stall force.

**WARNING: Photocell is highly recommended to be installed with the gate opener as entrapment protection for safety when you set stall force to the maximum.
Test the Reversing Sensitivity
For the sake of safety, it is very important to test the reversing sensitivity as soon as the control board set is finished.
The reversing sensitivity adjustment is an inverse correlation with stall force adjustment in potentiometer A and
B. In other words, the stall force level is higher; the reversing sensitivity level is lower.
Put an immobile object along the gate path, and then operate the gate to strike it during the close cycles. The gate must reverse as soon as the object is struck with it. If the gate doesn’t reverse, please increase the reversing sensitivity by turning the potentiometer in a counter-clockwise direction. (Turning the stall force potentiometer toward to MIN position to increase the reversing sensitivity)
Note 1: If the sensitivity setting is too higher, the gate will stop or reverses very easily by itself while there is little obstruction or resistance such as strong wind or heavy snow sometimes.
Note** 2: Always check the gate reversing function every time of control board is set or restarted after powering off.

How to Program or Erase the Remote

The remote MUST be programmed to the opener BEFORE OPERATING. Please follow the steps to program the remote.
Activate the opener only when the gate is in full view, free of obstruction, and properly adjusted. No one should enter or leave the gate area while the gate is in motion. DO NOT ALLOW CHILDREN to operate the push button or remote. DO NOT ALLOW CHILDREN TO PLAY NEAR THE GATE.
If you purchase additional remote controls, the gate opener must be programmed to accept the new remote code.
If you lose one of any remote control, please erase and reprogram all other remote controls to have a new code for safety. Program the remote Press and release the learn button, and the REM LED light will be on, then press the key in the remote two times in 2 seconds, between the two times HOLD ON FOR A MOMENT, and the REM
LED light will flash for 4 seconds. Now the remote has been programmed successfully.

Symptom	Possible Solution(s)
The opener does not run. The power LED is OFF.	1. Make sure that the power

cord is properly plugged into the main outlet.
2. Check if the output voltage of the transformer is 24VAC. If the voltage measures 0, the transformer may be overheated or damaged. Turn the power off and allow the board to cool for several minutes then reset. Replace the transformer if the symptom still exists.
3. Check the fuse in the control board. Replace the fuse if it was burnt out.
4. Check the status of the over-discharged LED on the solar controller, the voltage of the batteries is too low to power the gate opener if the LED is ON. Please wait the batteries are charged to full.
5. The solar controller could be faulty if the over-discharged LED is ON when the voltage of the batteries is normal (>24VDC).
6. Check the control board. Replace the control board if necessary.
The opener does not run. The power LED is ON.| 1. Check to be sure the beam is not blocked if a photocell is used as a secondary entrapment prevention device. If a photocell is not used, the photocell terminal of the control board should be shorted by a jumper wire.
2. Check the motor. Release the clutch then disconnect the wires of the motor from terminals 1 and 2. Connect the wires to the 24V battery directly, the motor should run, and then exchange the wires, the motor should run in the opposite direction. If the motor runs in both directions, please check the other parts listed below.
3. Check the limit switch. Use a jumper wire to short terminal 4 with terminals 3 and 5, and then use a keying device to operate the opener, replace the limit switch if the motor could run in both directions.
4. Check the control board. Replace the control board if necessary.
Remote control does not work.| 1. The indicator light of the remote control is not on. Check the battery in your remote control. Replace the battery if necessary.
2. The distance you use the remote is too far away from the opener. Try it again closer.
3. Remote control is not suitable for the receiver. After making sure the codes are correct, erase remote controls and then re-program the codes in the device.
4. Check the control board. Replace the control board if necessary.
The gate starts but it is immediately stopped or reverse| 1. Check the HALL sensor board on the side of the gearbox has been connected to the control board tightly.
2. Check that the clutch is adjusted properly and is not slipping.
| 3. The opening force or closing force is adjusted too small. Turn the potentiometer A&B to increase the force.
4. Disconnect the gate from the gate opener and check that the gate slides freely without any binding.
5. Check the control board. Replace the control board if necessary.
The gate opens, but stops, and will not return.| 1. Please note the two limit magnets are different: one is the N pole and another is the S pole. Please try to exchange the two magnets.
2. Please try to exchange the limit switch wires CL (close) and OP (open).
3. Maybe the magnet was installed in the wrong position so it inducts both witches. Adjust the magnets to the correct position refer to the manual.
4. Check the control board. Replace the control board if necessary.
The gate can open but fails to close.| 1. Photocell is obstructed. Remove obstruction.
2. The limit switch is failed. Use a jumper wire to short terminal 4 with terminal
3 and 5, and then use a keying device to operate the opener, replace the limit switch if the motor could run in both directions.
3. Check the control board. Replace the control board if necessary.
