SAFETY WARNIGNS Warning — It is vital for the safety of persons to follow all instructions. Failure to comply with the following safety rules may result in serious personal injury and/or property damage. For additional safety protection we strongly recommend the fitting of a photo electric beam. In most countries photo electric beam are mandatory on all garage doors fitted with automatic openers. For a small additional outlay ET Technology Co. Ltd. recommends that photo electric beams be installed with the automatic opener ensuring additional safety and peace of mind. Do not operate the garage door operator unless the garage door is in full view and free from objects such as cars and children/people. Make sure that the door has finished moving before entering or leaving the garage. Do not operate the garage door operator when children/persons are near the door. Children must be supervised near the garage door at all times when the door opener is in use. Serious personal injury and/or property damage can result from failure to follow this warning. Do not allow children to operate the garage door operator. Serious personal injury and/or property damage can result from failure to follow this warning. Regularly check to make sure that the safety obstruction force is working correctly, and is tested (by placing a 50mm high object on the floor) and set as per the installation instructions manual. Failure to follow the manual could result in serious personal injury and/or property damage. This test must be repeated at regular intervals and the necessary adjustments made as required. Do not disengage the door opener to manual operation with children/persons or any other objects including motor vehicles within the doorway. Wall switch or transmitter must be installed high enough and make sure children can’t reach them.
The door opener is not intended for use by young children or infirm persons without adequate supervision. Children should be supervised to ensure that they do not play with the remote transmitters or the operator. Keep hands and loose clothing clear of the door and door opener at all times. If the roll up door is the only entrance to the garage, a back up battery must be installed and checked weekly. The unit should be installed so that it is protected from the elements. It should not be exposed to water or rain. It is not to be immersed in water or sprayed directly by a hose or other water carrying device. The garage door must be well balanced. Sticking or binding doors must be repaired by a qualified garage door installer prior to installation of the operator. Frequently examine the installation, in particular cables, springs and mountings for signs of wear, damage or imbalance. Do not use the door if repair or adjustment is needed since a fault in the installation or an incorrectly balanced door may cause injury. Do not attempt to repair the door yourself as hardware is under extreme tension. Remove or disengage all garage door locks and mechanisms prior to installation the operator. Connect the garage door operator to a properly earthed general purpose 240V mains power outlet installed by a qualified electrical contractor. The outlet (and operator) must be positioned so that it is easily accessible. Disconnect the power cord from mains power before making any repairs or removing covers. Only experienced service person can remove covers from garage door operator. When using auto close mode, a photo electric beam must be fitted correctly and tested for operation at regular intervals. Extreme caution is recommended when using auto close mode. All safety rules must be followed. In order for the garage door opener to sense an object obstructing under the door way, some force must be exerted on the object. As a result the object, door and/or person may suffer damage or injury.
If the circuit is damaged, it must be repaired by a qualified person. Make sure that the door is fully open before driving in or out the garage and fully closed before leaving the driveway. Make sure that remote controls are kept out of reach of children. PRODUCT FEATURES 1. Easy to use.

1. CODING TRANSMITTER The operator should be under standby mode when coding transmitters. Open the semi-transparent cover and press K1 button, the coding light will be on and the operator is under transmitter learning mode. Press any button on the transmitter, the coding light will be off. Press the same button again the coding light will flash for 8 times then off. The transmitter has been coded successfully. The same way to code other transmitters. Press the K1 button and hold on for over 8 seconds the coding light will be off, all storage will be cleared. Press the K1 button and release within 8 seconds. If the coding light flash and then off, it means the memory is full. The operator can learn 20 transmitters at most. 2. DOOR TRAVEL LIMIT SETTING 2.1 Pull down the clutch handle and make sure the door is under manual operation mode. 2.2 Raise the door to a suitable height then adjust the limit adjustment knob B and stop whenever there is a ‘tick’. 2.3 Close the door then adjust the limit adjustment knob A and stop whenever there is a ‘tick’. 2.4 Open and close the door again and make sure there’s a ‘tick’ when the door moves to the up and down limit position. Otherwise, the limit should be fine-tuned. 2.5 Push the clutch handle and rise and pull the door to engage the clutch gear. 2.6 To ensure the up and down limit positions again by press the O/S/C button on the operator. Adjust the limit correspondingly if needed. 2.7 Notes: - Before setting the travel limit, turn the slide block far away from the limit switch in case of setover.
- When setting the travel limit, the slide block should be moved in downward direction and then touch the limit switch, the motor won’t work if the slide block moves in a wrong direction. - When setting the travel limit, push the bottom of limit adjustment knob A or B by a cross screwdriver then you can adjust the travel limit by turning them. - When left installing, the limit adjustment knob A and B perform an opposite function compare to right installing. 3. SAFETY OBSTRUCTION FORCE MARGIN THIS IS INPORTANT, IF THIS IS NOT DONE CORRECTLY, THE UNIT MAY BE DAMAGED. 3.1 Open the semi-transparent cover and adjust the opening resistance adjustment knob. About 20 kg of opening resistance is recommended. When the opening resistance reaches 20 kg the motor won’t work. (To add the resistance by clockwise rotation, to decrease the resistance by counterclockwise rotation) 3.2 Adjust the closing resistance adjustment knob. 5-15 kg resistance is recommended. 4. Connection of photo beam Connect the photo beam to the interfaces ‘I’, ‘OV’ and ‘+24V’ as per FIG. 8. The photo beam should be controlled by switch value, normally open type. The wire can go through cord hole H (FIG. 9). 5. Connection of back up battery Connect the back up battery to the interfaces ‘sp+’ and ‘sp-’ on PCB as per FIG. 10. The battery must be lead-acid battery. The wire can go through cord hole H (FIG. 9).
