[. . . ] 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. Improperly designed, installed or maintained systems can create risks for the user as well as the bystander. Gate systems design and installation must reduce public exposure to potential hazards. [. . . ] One ore more contact sensors shall be located at the leading edge, trailing edge, and post-mounted both inside and outside of a vehicular horizontal slide gate. Figure 2 Doc 01-20220 Rev D Safety Information 9 ORNAMENTAL 'GRILL TYPE' GATES Injuries occur when people put their hands and arms through openings in the grill and the gate is operated. They cannot retract their arms and it gets caught between the moving gate grill and the stationary fence post or fence. This potential hazard can be averted by placing a screen mesh on the gate to prevent access through openings anywhere the gate may travel. Figure 3 Doc 01-20220 Rev D 10 Preparing the Installation Preparing the Installation Pre-installation Check List !If necessary, lubricate, adjust or repair the gate prior to operator installation. They may require a backframe to be constructed to allow for chain attachments. Double check the size and weight of the gate to make sure that this operator is proper for this application. If wiring has already been installed, check to make sure it meets the following specifications and requirements. Wiring Specifications A. The distances shown are measured in feet from the operator to the power source. These calculations are based on the National Electrical Code and allows fro a 5% voltage drop. Supply voltage must be within 10% of the operator's rating under load conditions. It is highly recommended that only 90% of the distances shown be used; this will allow for a 10% safety factor. POWER WIRING Single Phase ­ 120 Vac. When wire larger than 12 gauge is used , a separate junction box will be required for operator power connections. Do not run or parallel conductor cable for controls. CONTROL WIRING One Way Distance 800 ft. Wire Gauge 18 16 14 Table 3 Doc 01-20220 Rev D Preparing the Installation 11 DO NOT RUN OPERATOR UNTIL INSTRUCTED! OPERATOR MUST BE PROGRAMMED BEFORE OPERATION. Operator Features Internal Obstruction Sensing on Circuit Board Motor Brake Power DisconnectEmergency Stop Battery Circuit Breaker 01-20220F7 Figure 5 BATTERY BACK-UP Should there be a power failure, the model SL500-11 will automatically switch over to battery back up to run the gate. If battery is fully charged, it should be able to run a standard size gate many complete cycles, (cycle = one full open and one full close). If dilute sulfuric acid contacts skin or clothes, wash immediately with water and contact a doctor. Doc 01-20220 Rev D 12 Preparing the Installation . INTERNAL OBSTRUCTION SENSING Built-in motor current monitor. Will automatically 'Learn' the current that the motor is using to open and close the gate. During gate operation, should the current rise above the learned setting (because of gate obstruction), the model SL500-11 will react. See program settings for more details. POWER DISCONNECT SWITCH/EMERGENCY STOP This switch will turn power (120 vac. ) off at the operator. When turned off, the operator will immediately stop if it was running. SPRING APPLIED, ELECTRICALLY RELEASED BRAKE The purpose of the brake is to minimize overtravel caused by gate coasting. An added feature of the brake is to assist in preventing backdriving of the gate. [. . . ] 'BLINKS' when the control voltage of the operator drops below 10. 5 VAC. See not below. Red Table 4 NOTE: PROGRAM 2 (MASTER/SLAVE) When setting up a master/slave system, both operators MUST be programmed independently. Program 1: One operator will be set to #1 the other will be set to #2. Program 2: One operator will be set to #1 the other will be set to #2. [. . . ]
