  • Page 6: Safety Information

    Safety Information Safety Information Vehicular gate systems provide convenience and security. Gate systems are comprised of many component parts. The gate operator is only one component. Each gate system is specifically designed for an individual application. Gate operating system designers, installers and users must take into account the possible hazards associated with each individual application.
  • Page 7 Safety Information Adjust clutch or load sensing device to minimum force setting. Do not overtighten clutch or adjust force setting above minimum. Install controls where user cannot touch gate while operating controls. Install two or more warning signs on the gate to alert persons in the area of automatic gate operation.

    Safety Information Safety Precautions for Swing Gates and Ornamental “Grill Type” Gates ENTRAPMENT ZONES Pedestrians must stay clear of the gate path, particularly the area where the gate can trap them, as shown in Figure 2. 01-G0610F3 Figure 2 Gate edges and/or photo-electric beams must be incorporated into the swing gate system to assist in the protection of people who may come near the gate operating system.
  • Page 9: Preparing The Installation

    Preparing the Installation Preparing the Installation Pre-Installation Check List Check the gate. It MUST operate smoothly and freely. If necessary, lubricate the hinges, adjust or repair the gate prior to operator installation. The gate MUST be level. Double check the size and weight of the gate to make sure that it is proper for this application. If wiring has already been installed, check to make sure it meets the following specifications.

    Troubleshooting Troubleshooting When troubleshooting, one of the first things to do is try to isolate the problem area. The five (5) main areas to check out are: Power Accessories Operator’s Primary Voltage Operator’s Low Voltage Gear Reducer 1. Power Always use extreme caution! Some possible symptoms of power problems include: The obvious one is –...
  • Page 28: Accessories

    Troubleshooting 2. Accessories Add-on accessories can create many of the problems that are credited to the operator. Many applications have more than one accessory item attached to the operator and some of these items even draw their power from the operator. Some of the symptoms that can show up because of accessories: The operator won’t close.
  • Page 29: Low Voltage Circuit

    Troubleshooting If there is power, then check for it at the transformer primary terminals. If there is voltage at the switch and none at the transformer, then you probably have a bad power disconnect and it should be replaced. If the problem is thought to be the motor, it is recommended that it be replaced. It is possible that the thermal overload inside the motor has overheated.
  • Page 30: Gear Reducer

    Troubleshooting 5. Gear Reducer If physical signs show a seal has broken in the gear reducer, it may be necessary to replace the reducer. When replacing the gear reducer oil, use Mobil1 10W-30 synthetic oil or equivalent. The oil level for the gear reducer allows gear to be dipped but not submerged in oil. DO NOT overfill gear reducer oil reservoir.
