[. . . ] This safety alert symbol means "Caution" - failure to comply with such an instruction involves risk of personal injury or damage to property. This gate drive mechanism is designed and tested to offer appropriately safe service provided it is installed and operated in strict accordance with the following safety rules. Incorrect installation and/or failure to comply with the following instructions may result in serious personal injury or property damage. When using tools and small parts to install or carry out repair work on a gate exercise caution and do not wear rings, watches or loose clothing. [. . . ] With a new drive mechanism, the release action may sometimes feel stiff/jerky. Release and Engage Place the hexagonal key into the hole provided in the cover. Push the released drive onto the fittings and secure it by using the supplied bolts and rings. 80 cm long and is laid in a curve to the controller or a watertight distribution box located above ground. An approved cable is permanently installed from the distribution box onwards. The capacitor can be connected inside the distribution box or in the controller. Check that the gate fittings and the drive mechanism are securely fixed at regular intervals (monthly). Unless the gate runs smoothly it will not operate correctly with the drive mechanism. The drive cannot eliminate the problems caused by a gate that does not work satisfactorily. Mounting the motors, laying the necessary cable and fitting light barriers or contact strips. If installation is to be performed in a permanent location, a means of disconnecting the equipment from the mains supply with a contact clearance of at least 3 mm is needed (master switch). Please note: in these instructions, relay contacts are designated NC (normal closed) or NO (normal open). NO contacts are open and close Humidity and water will destroy the control board. Always make sure that water, humidity and condensation cannot enter the control box. It is vitally important that all openings and cable glands are sealed so that they are watertight. Wall plugs ELECTRICAL INSTALLATION Installing the electronic control board: the motor control board is a microprocessor-controlled electronic appliance featuring state-of-the-art technology. It is equipped with all the connecting options and functions needed to guarantee safe operation. The control box incorporating the motor control board should be installed with the cable intakes pointing downwards fig. The electronic equipment enables the pull and push forces to be set with great accuracy. If installed and set correctly, the gate/door can be stopped manually. When in motion, the gate/door can be stopped at any time by operating the remote control, the push-button or the keyoperated switch. The gate/door wing must be fitted with a robust end stop for the 'OPEN' and 'CLOSED' positions as the gate/door drive has no limit switches. [. . . ] The control unit has two self-learn channels and is therefore able to open or close one gate/door or both gates/doors simultaneously via appropriate operation of the handset. Should, for instance, channel 1 (2) receive the handset's remote control code, only one wing will be opened. If you teach the remote control on channel 2 (1), you will be able to open both wings via the appropriate push-button. To memorize the code all you need do is press the button of your choice on the handset and keep it depressed while, at the same time, briefly pressing the self-learn button on the electronic unit with the other hand.
