4 Product Information And Specs. POWER SUPPLY The 24 DC operator requires 115 VAC power. The gauge wire depends on the distance run. Consult your electrician to ensure a good power supply. PROTECTION (See Figure 2) Fuses for primary and secondary power: 1.6 Amp. 250V (line) 6.3 Amp 250V (control) 12 Amp. 250V (motor) A varistor protects primary and secondary power over voltage. Operator torque control adjusts the maximum output force of the operator (see Figure 13, Potentiometer #1). CHARACTERISTICS Solid state control panel allows the control of (2) 24 VDC, 120W actuators as follows: Single button and Radio control command to: OPEN STOP CLOSE STOP Separate inputs for Open (with timer to close) and Stop Timer to close built in Safety input to stop the gate and to reverse the gate during closing cycle Adjustable decel. speed, motor speed, motor power, and slave delay time Electrical, Control Connections The Eurostyle type connectors used in the LA405-24 control accept (2) stripped 16 gauge wires. Dry contact control wires (no power) can fit more than (2) wires if smaller than 20 gauge wire is used. Length is limited to 40 feet.
Preparations 5 Preparations Site Preparation Using a licensed electrician, route power and control wires to the operator using appropriate conduit and wire for your local code. Ensure gate swings freely and is level. Controls should be mounted away from gate so people on the opposite side of the gate cannot reach through and start the gate (see Figure 3). NOTE: Plan gate location for accessories such as loops, photos eyes, etc. before beginning installation.

6 Preparations Site Layout NOTE: For push to open only position plate F as shown in Figure 4. Plate F Push to Open (optional) Pull to Open (typical) 01-G0399F15 Figure 4
Installation 7 Installation Mechanical 1 Attach plate F to the post so it is halfway between the ground and the top of the gate. 2 Slide Plate F into bracket H and secure with bolt E and nut G. 3 When the gate is closed, attach plate B to the gate at the same height as plate F. 4 Gate bracket B should be mounted approximately 23-1/4 from the gate hinge point. The installed bracket must provide a level operation for the operator. 5 Test the location before welding. NOTE: When the gate is full open or full close, the unit should not be at the end of its stroke. Refer to Figure 5. Figure 5 01-G0399F21
8 Installation Electrical 1. The electrical installation must meet national and local codes and should be performed by a qualified electrician. 2. Read all manuals and safety instructions before beginning installation. 3. It is strongly recommended that safety equipment be used with this operator. 4. Power cables should be run in separate conduit from the control wiring. 5. Check all connections before applying power to units. 6. When voltage is supplied, the Power LED should be on. 7. If motor direction is not correct, reverse the open/close motor wires. Or as an alternate method, you may also reverse the FCA-FCC limit switch wires. 8. The term normally open means that the contact points are open or apart until they are brought together by electrical (radio receiver) or manual means (pushbutton). 9. The term normally closed means that the contact points are together or closed until opened by electrical or manual means. LINE POWER CONNECTIONS 1 Connect incoming line wires to the 3 pole terminal on control board. 2 To attach power wires to the unit, remove the cover screw holding black plastic power cover (see Figure 6). This can be found in the lower right hand corner of the control box. 3 Attach the hot (black), neutral (white) and ground (green) wires as indicated on the control board. Figure 6 SAFETY DEVICES (PHOTO EYES AND LOOP DETECTORS) The LA 405-24 control box allows for (2) different safety inputs. The first uses terminals #1 and #6; when activated it reverses a closing gate. The second type uses terminals #1 and #5; when activated it stops the gate (will not open or close). If gate was opening when obstruction occurred, once clear, the gate will continue to open. If gate was closing when obstruction occurred, once clear, the gate will then begin reopening. Both require connection to devices with normally closed contacts, which are opened when activated. WARNING Use of safety devices is recommended to prevent injury and entrapment. STOP COMMAND Mount a stop button near the gate. This allows the gate to be stopped in the case of an emergency. A normally closed stop button suitable for exterior use should be used. The connections for the stop button are #1 and #7.
Installation 9 LOCKING DEVICES (ELECTRICAL DEAD BOLT) Locking devices may be used with the LA405-24 control panel. A 24V DC, 50W output is maintained for 3 seconds when an open command is given. The terminal connections are #15 and #16. RADIO CONTROLS AND SINGLE PUSH BUTTON STATIONS Each control box comes pre-wired with a LiftMaster 412HM receiver. This receiver (or others) are wired to terminals #1 and #2. Radio power is connected to terminals #17 (+) and #18 (-) for 24V DC. SAFETY EDGES Electric gate edges are normally open devices. To wire an electric gate edge to a LA405-24 control panel, an auxiliary relay must be used. The procedure is a follows: Attach one of the two electric gate edge wires to terminal #17 Attach the other wire to one of the coil terminals of a 24V DC relay (P/N 24-264-4) Attach the remaining coil terminal to terminal #8 Attach the common and the normally closed contacts of the 24V DC relay to terminal #1 and #6 When the gate edge is contacted, the 24V DC relay will be energized causing an open circuit between terminals #1 and #6. The gate operator will then reverse to the full open position. KEYPADS/CARD READERS (See FIGURE 7) Use terminal #1 and #3 for an open command only. The gate will time out and close if the timer is activated. Figure 7 AUDIO AND VISIBLE ALARMS Warning devices may be used with the LA405-24 actuator. 24V DC, 50 W is supplied upon opening and 3 seconds before closing. 24V DC, 50W warning devices are connected to terminals #12 and #14. When a safety command is received across terminals #1 and #5, actuator will stop but flasher will continue until open or close limit switch is met.
10 Installation CONTROL CONNECTIONS For each actuator, run (2) wires, 5 to 25 feet long of 14 gauge wire for power. Use (3) wires 16 to 20 gauge for the controls. If using (2) actuators, use motor cables of the same length and gauge to ensure the motors run at the same speed. NOTE: When actuator wiring is run to the bottom of the operator, mount using this hold (! -- see Figure 8) to prevent plate from shearing cables. 01-g03099F22 Figure 8 WARNING If operator does not stop in time, the plate may cut the cable.
