4 4 Specifications & Capacities Specifications & Capacities The HL410-21and Hl410L-21 operators are light duty commercial gate operators designed to operate a typical swing gate. Because operating requirements and gate construction vary by installation, the capacities shown should be used as a guide to determine the expected performance of the unit. HL HL410L-21 A 26 1/2 31 3/8 B /4 DRIVE UNIT B A (Retracted) F3 CONTROLLER / /2 3 1/2 16 Figure 1 MAXIMUM LENGTH VS. MAXIMUM WEIGHT 0-8ft 900 lbs 8-10ft 900 lbs 10-12ft 900 lbs Table 2 Contact a LiftMaster dealer if your application exceeds any of the recommended limits to determine the proper unit needed.! Double Check Operator Capacities!! Do not use this operator on walk or pedestrian gates.! Do Not Misapply Product. Warranty will be void!

5 Specifications & Capacities 5 NOTE The hydraulic locking is not intended to be a replacement for security type locks. External lock systems should be used if: High security is required for the installation. The length of the gate exceeds 12 feet. The gate has a large surface area. The installation area could have a strong or gusty winds. SPECIFICATIONS Cycles per hour (Full open & close) 20 maximum Time to open 19 seconds Hydraulic (gate) Locking (!) Both Directions Primary Voltage 230 VAC ~1 ~ 60hz Secondary Voltage 24 VAC Power Consumption 345 W (full load) Motor R.P.M 1700 Motor Overload 135 C Fluid Shell LHM Table 3! It is highly recommended that you reconsider using this type of gate operator on any solid faced gate, without an external lock system on both the open and closed position. Strong winds will greatly affect the efficiency of this operator on these types of gates. IMPORTANT NOTE The gate must be level and operate smoothly and freely. If it does not, damage to the operator may result and the life expectancy will be greatly reduced.

6 6 Safety Information Safety Information Automatic gate operators provide convenience and security to their users. However, because these machines can produce high levels of force, it is important that all installers and users be aware oft he potential hazards associated with improperly installed or adjusted units. The information on this page contains various safety precautions and warnings, some highlighted with this symbol (see left margin). This symbol will identify conditions that can result in serious injury or death. Take time to read and follow these precautions and the other information provided. NOTE This operator is intended to be a part of a total gate operating system. It is the responsibility of the purchaser and installer to ensure that the total system is safe for its intended use. Installer BEFORE INSTALLATION 1 Check to see that this is the proper operator for this application. (See page 4). 2 Ensure that the gate has been properly installed and works freely in both directions. Repair or service any worn or damaged gate hardware. 3 Install the gate operator on the inside of the property and/or fence line. Do not install an operator on the public side of the gate. 4 If the gate is near a residential area, or pedestrian traffic is expected near the gate, additional safety equipment such as electric gate edges or photocell detectors must be installed to prevent entrapment. Severe injury or death can result from entrapment with the gate. 5 Certain types of gates can create greater hazards to pedestrians. Any gate that has exposed, reachable pinch points or is constructed to allow arms and legs to pass through it is a potential hazard. These hazards should be guarded against. 6 Review the operation of the unit and become familiar with the manual disconnect system and safety features of the unit. 7 Outdoor or easily accessed controls should be of the security type to prohibit unauthorized use of the gate.

7 Safety Information 7 DURING INSTALLATION 1 Be aware of all moving parts and avoid close proximity to any pinch points. 2 Disconnect power at the service panel before making any high voltage power connections. 3 Place controls far enough from the gate so that a user can see but cannot touch the gate while operating the controls. 4 Place warning signs provided on the gate or in a high visibility area to alert of automatic gate operation. AFTER INSTALLATION End User 1 Make sure the user understands the basic function and safety features of the system. 2 Leave this manual and the troubleshooting guide with the end user. 1 Periodically check all the safety systems. If these functions are observed to operate improperly, discontinue use and contact a professional for service immediately. 2 Follow recommended maintenance schedule. 3 Do not allow children to play on or near the gate operating system. 4 Never operate the gate until you have it in full sight. 5 See Hydraulic Adjustments on p. 16 for pressure valves and manual disconnect information.

10 10 Installation Installation Step 1: Gate Stops The gate must have a permanent gate stop at the full closed position. It is also highly recommended that there be a gate stop at the determined full open position. These are to prevent the piston from bottoming in the cylinder and to prolong the unit s life. Step 2: Gate Brackets 1 Locate the positions of the front and rear mounting brackets. It is recommended that these brackets be positioned at the midpoint between the gate hinges. It is very important that they be in-line with each other! The operator must be level. 2 The two brackets should be welded to the gate and the post as shown. They can be welded directly or modified to suit your particular application. Do not weld brackets with operator attached. Avoid getting weld splatter on the piston rod. Keep piston rod clean and smooth. Avoid nicks.

11 Installation 11 Step 3: Optional Mounting OUTWARD SWING WARNING Do not install outward swing gates in applications where gates will swing into public area. Serious injury could result from someone being hit by the gate. Use outward swing gates only in applications where the gate will open into secure area and where the person operating the gate has control of traffic in the path of the gate. Do not use the Open Only mode of the controller for an outward swing gate installation. A. Gate stops must be used at both the full open and close positions (see Step 1). B. Follow Step 2 for mounting of gate brackets. The difference being that the rear mounting point is 5 to the right of the hinge point instead of 5 to the left as shown in Step 2 (distance between mounting points is 27-1/2 instead of 37-1/2 ). C. The piston rod should be fully retracted when the gate is in the closed position. The unit should be mounted with the gate in the closed position (see Step 4). D. Proceed to Step 5. Follow wiring for outward swing. LARGE PILLARS OR WALLS If the dimension from the centerline of the gate to the outer edge of the pillar or wall is 3-3/4 or less, you can notch out part of the pillar or wall (see Example A Figure 4) as shown. If this dimension is larger than 3-3/4, then it will be necessary to notch out larger portion (see Example B Figure 4) large enough to house the unit. The notch should be 5 to 8 high. Contact a LiftMaster dealer if your application does not fit these guidelines. OPTIONAL MOUNTING - NOTCH AS REQUIRED F6 EXAMPLE A Figure 4 EXAMPLE B

12 12 Installation Step 4: Mounting 1 Manually open the gate and attach the unit to the two (2) mounting brackets (see Figure 5 below). 2 Manually open and close the gate a few times to ensure the mounting brackets and gate stops are positioned properly with no interference (the unit is shipped in the disconnect position to allow for this). 3 Mount the controller in a convenient location, within reach of the unit s 4 ft. control card. Make sure the cord is not stretched taut (it should have a slight amount of slack during the full cycle). 4 For Master/Slave Option: Mount both units. Mount the controller near the master unit and the junction box near the slave unit. REAR MOUNTING PIN FRONT MOUNTING CLIP C-CLIP CONTROLLER CONTROL CORD 3 MAX F7 GATE SHOWN CLOSED Figure 5

16 16 Installation Step 7: Hydraulic Adjustments 1 Locate the by-pass valve. Using the hex key supplied, re-engage the by-pass valve by turning it clockwise as far as possible. 2 Turn power on at main power supply and at power disconnect switch. The controller has a 7 second delay form power-up until a signal can be received. 3 With gate open, activate the unit to close. Using a flat blade screwdriver, slowly turn the close pressure valve counter-clockwise until the gate begins to move, then adjust it ¼ to ½ turn more. (Unit is shipped with pressure valves set at minimum). NOTE Since the unit s cycle time has yet to be adjusted, it may shut off too soon or may run longer than desired. 4 Locate the open pressure valve. Activate the unit to open and adjust it in the same manner as the close direction. WARNING The open & close pressure valves must be adjusted properly. They should develop enough force to open and close the gate properly. If the gate meets an obstruction there will be a minimum amount of force applied. Check this by holding the gate when it is closing and opening. For manual operation of the gate, use the hex key and turn the by-pass valve counter-clockwise to disconnect the unit. To reconnect the unit turn the by-pass valve clockwise. Never adjust the open and/or close pressure valves to their maximum setting. Always use the minimum setting required to move the gate. If strong wind loads are a possibility, increase the run time not the pressure valves. Plastic Cover Disconnect Key Top View By-Pass Valve Close Pressure Valve Open Pressure Valve Figure 9 Bottom View F11

17 Installation 17 Step 8: Adjustments 1 Locate the cycle timer pot on the control panel. This pot determines the length of time the unit will run. Adjust it so the unit will fully open and close the gate properly. Allow a few seconds for slippage against the gate stops. 2 Optional: If you have a master/slave system and have added the master/slave delay relay, locate the master/slave delay pot on the control panel. This pot determines the close time delay between two units (i.e. the master closes first). Adjust this pot to the desired delay time. NOTE: Both units will open at the same time. 3 Optional: Locate the auto close timer pot on the control panel. This pot determines how long the gate will stay open before it automatically closes. Adjust this to the desired time. Reversing edges, obstruction sensors and inductive loop detectors should be used with this feature to prevent injury or property damage Figure F12

18 18 Installation Step 9: Rod Cover Install the rod cover over the piston rod, as shown. IMPORTANT NOTE: The cover must be installed to keep the piston rod clean and nick-free. Figure F13

19 System Check-Out 19 System Check-Out LiftMaster strongly recommends that at this time you check out the entire system. 1 Make sure the unit fully opens and closes the gate properly. 2 Check all controls that activate the gate to ensure they are working properly. 3 It is extremely important that all safety devices be checked and double checked. 4 Double check the manual operation features and pressure valves of the system. NOTE: If a problem should arise, see the Model HL Troubleshooting Guide. AND FINALLY... Install the gate caution on both the inside and outside of the gate where they can be easily seen. LiftMaster recommends that you pad-lock the controller door. Inform the customer of this recommendation. Make sure the unit and controller are free of grease or dirt. Clean if necessary. Clean up the area around the gate. Look around for any tools or equipment that may be left. Please leave this manual and the troubleshooting guide with the customer.
