Installation (continued)

4 Prepare the Arm

1. Reference arm installation instructions included with the arm packaging. Arm should be mounted with the edge mounting channel facing toward the ground.
2. Arm Sensor Setup: The Breakaway Arm Setup uses a breakaway sensor that is located on the arm bracket and a magnet that is located on the arm to detect the presence of the arm. This magnet must be in place for all arm bracket configurations**.

**If the sensor is not installed, the operator will not run.

NOTE: The magnet position is fixed in the bracket. The position of the magnet on the arm needs to align with the magnet in the bracket. The two flat portions should make contact as shown in figure.

Diagram: Shows two circular magnets, one labeled "Magnet", with arrows indicating their alignment. The text describes the magnet on the arm needing to align with the magnet in the bracket, with flat portions making contact.

5 Install the Barrier Arm

ATTENTION: Torque the 3 bolts fastening the counterbalance spring assembly to 30ft*lbs. If springs are removed, the hub set screws and the 2 end plate bolts need to be torqued to 30ft*lbs.

ATTENTION: Before installing the arm, verify the arrow printed on the springs points in the direction of the arm in the closed position. If it does not, refer to "Reverse the Spring Handing" on page 16 for instructions.

1. Ensure the operator is powered off.
2. Remove the operator cabinet door and set aside.
3. Unpack the arm bracket and hardware from the operator cabinet.
4. Cut the barrier arm to desired length if modification is necessary.
5. IMPORTANT: Do not cut end with mounting system.
6. Verify that the appropriate number of counterbalance springs are installed and align the arrows to match the intended arm direction. If the arrows pointing opposite the intended arm direction, remove the counterbalance spring assembly and flip to ensure the arrows align with the intended arm direction. Follow the instructions and warnings in "Modify Spring Count" on page 16.
7. Loosen the four screws on the arm bracket and remove the hinge screw from the arm bracket.
8. Slide the arm bracket on to the output shaft of the operator. Do NOT tighten down the hub bolts. The arm bracket should freely rotate at this point.
9. With the far end of the arm resting on the ground, push the arm into the arm bracket. Be sure to install the arm with the arm magnet toward the operator.
10. Choose the arm installation type using the table on page 18 and follow the corresponding instructions:

Arm Installation Table

NOTE: Permanent damage may occur to the system if the arm is struck.

Diagrams: Illustrate the steps for Swingaway, Breakaway, and Fixed arm installations.

NOTE: Do not tighten hub bolts on output shaft until rotated to the vertical position.

10. Rotate the arm bracket vertically so that the arm is in the open position.

NOTE: Fasten each of the four hub bolts with the arm in vertical position.

11. Torque each of the four hub bolts to 60 ft-lbs (this torque is critical).
12. Connect the operator wiring harness to the barrier arm wire harness.
13. Route the arm bracket wiring harness through the hold down. Install harness hold down to the appropriate location for the handing of the operator using the standoff and washer (see image below).
14. If an LED arm is being installed, connect the arm LED harness to the arm bracket harness (see detailed instructions included in the arm documentation).
15. Turn on barrier arm gate operator power.
16. Set the Arm length and the arm speed on the LCD Menu.

NOTE: If Limit Switch on the Hub is triggered please see appendix for instructions on how to reset it. Ensure the springs are in the correct orientation for the arm direction and begin setting limits. Start with the arm in the vertical/up position.

Diagram: Shows "Hub Bolts" with an arrow pointing to them.

FIXED BARRIER ARM SENSOR SETUP

The Fixed Barrier Arm Setup also requires the use of a breakaway sensor that is located on the arm bracket and a magnet that is located on the arm to detect the presence of the fixed arm.

Diagram: Shows two diagrams illustrating the fixed barrier arm sensor setup, indicating the "Direction of arm" on both sides.

6 Install External Safety Devices

WIRE SAFETY DEVICES

There are three options for external safety devices depending on the specific device and how the device functions. Refer to the manual included with your device for more information. These device inputs are for monitored devices, which include pulsed photoelectric sensors, resistive edge sensors, and pulsed edge sensors. Only one monitored safety device may be wired to each input. Additional monitored safety devices may be wired to the expansion board.

NOTE: Board inputs for safety devices are yellow.

NOTE: Any monitored devices that are removed from the unit need to be unlearned in the menu. Otherwise the operator will not function.

MAIN CONTROL BOARD

CLOSE EYES/INTERRUPT

(2 Terminals) The CLOSE EYES/INTERRUPT input is for photoelectric sensor detection for the close direction. When an obstruction is sensed during barrier gate closing, the barrier gate opens to the full open position and resets the Timer-to-Close. This input is disregarded during barrier gate opening.

CLOSE EDGE

(2 Terminals) The CLOSE EDGE input is for edge sensor detection for the close direction. When an obstruction is sensed during barrier gate closing, the barrier gate reverses to the full open position and resets the Timer-to-Close. This input is disregarded during barrier gate opening.

OPEN EYES/EDGE

(2 Terminals) The OPEN EYES/EDGE input is for photoelectric sensor or edge sensor detection for the open direction. When an obstruction is sensed during barrier gate opening, the barrier gate stops. This input is disregarded during barrier gate closing.

Diagram: Shows connections on the control board with labels like "CLOSE EYES/INTERRUPT", "CLOSE EDGE", "OPEN EYES/EDGE", "COMMON", and external device connections like "Close Photoelectric Sensors", "Close Edge", "Open Photoelectric Sensors OR Open Edge".

EXPANSION BOARD

EYE ONLY and COM

Open or Close Direction Photoelectric Sensors, the functionality is based on the switch settings (located next to the terminals).

• Switch set to CLOSE: Barrier gate reverses fully when an obstruction is sensed.
• Switch set to OPEN: Gate stops when an obstruction is sensed.

EYE/EDGE and COM

Open or Close Direction Photoelectric Sensors or Edge Sensor, the functionality is based on the switch settings (located next to the terminals).

• Switch set to CLOSE: Barrier gate reverses fully when an obstruction is sensed.
• Switch set to OPEN: Gate stops when an obstruction is sensed.

WIRELESS EDGE

Connection for wireless edge receiver.

NOTE: ONLY one wireless edge receiver may be connected to an operator. Up to 4 wireless edge transmitters LMWETXU may be programmed to the receiver.

Diagram: Shows connections on the expansion board and a diagram of a wireless edge receiver and photoelectric sensors/edge sensors.

7 Accessory Wiring & Expansion and Relay Adaptor Boards

ACCESSORY WIRING

All control wiring used to connect external devices to Class 2 circuits of the operator must be (QPTZ) Power-Limited Circuit Cables, Type CL2, CL2P, CL2R, or CL2X or other cable with equivalent or better electrical, mechanical, and flammability ratings.

EXTERNAL CONTROL DEVICES

EXIT

(2 Terminals) This input is a soft open command (maintained switch does not override external safeties). Used for exit probe, telephone entry, external exit loop detector, or any device that would command the gate to open.

• Opens a closed or closing gate and holds open an open gate, if maintained, pauses Timer-to-Close at OPEN limit.

SHADOW

(2 Terminals) This input is used for external shadow loop detector when loop is positioned under the swing of the gate.

• Holds open gate at open limit.
• Only active when the gate is at the OPEN limit, disregarded at all other times.
• Pauses Timer-to-Close at OPEN limit.

INTERRUPT

(2 Terminals) This input is used for an external interrupt loop detector when loop is on the outside of the gate.

• Holds open gate at open limit.
• Stops and reverses a closing gate to open limit.
• Pauses Timer-to-Close at OPEN limit, activates quick close and anti-tailgate features when enabled on the expansion board.

Diagram: Shows connections on the control board for Exit, Shadow, Interrupt, and their respective loop connections.

MISCELLANEOUS WIRING

Three Button Control Station (4 Terminals)

• OPEN and COM: Opens a closed gate. Hard open (maintained switch overrides external safeties). If maintained, pauses Timer-to-Close at OPEN limit. Opens a closing gate and holds open an open gate (within line-of-sight). Re-enables Timer-To-Close at OPEN limit if canceled by Stop command.
• CLOSE and COM: Closes an open gate. Hard close (maintained switch overrides external safeties within line-of-sight)
• STOP and COM: Stops a moving gate. Hard stop (maintained switch overrides Open and Close commands). Cancels Timer-to-Close at OPEN limit. Overrides Open and Close commands (within line-of-sight).

Fire Department Open Input (2 Terminals)

Acts as hard open.

Maintained input overrides (ignores) external safeties (photoelectric sensor and edge), pauses Timer-to-Close momentary input logic as single button control and safeties remain active, re-enables Timer-to-Close.

Accessory Power Class 2 Supply 24 VDC, MAX 1 Amp (4 Terminals)

• SWITCHED: Switched ON with gate motion and at the open limit when Timer-to-Close is active. Turns off 5 seconds after motion.
• UNSWITCHED: 24 VDC voltage out to power accessories, always ON.

Diagrams: Shows control board connections for Three Button Control Station, Fire Department Open, and Accessory Power.

EXPANSION AND RELAY ADAPTER BOARDS OVERVIEW

Diagrams: Shows the Expansion Board and Relay Adapter Board with numbered components.

1. QUICK CLOSE switch: OFF: No change to the gate's normal operation. ON: When Interrupt loop is deactivated it causes an opening or a stopped gate to close (ignores the Timer-to-Close).
2. AC FAIL switch: OPEN: Loss of AC power causes the gate to open approximately 15 seconds after AC power fail and remain OPEN until AC power is restored (enabling the Timer-to-Close). BATT: With loss of AC power, gate remains in present position and operator is powered from batteries.
3. EXIT FAIL switch: When set to OPEN, if the EXIT plug-in loop detector (Model LOOPDETLM) detects a fault, then the gate opens and remains open until fault is cleared. When set to CLOSE, then plug-in EXIT loop detector faults are ignored (EXIT loop is faulted and inoperative).
4. ANTI-TAIL switch: OFF: When Interrupt loop is activated it causes a closing gate to stop and reverse. ON: When Interrupt loop is activated it causes a closing gate to pause. Once the vehicle is clear the gate continues to close.
5. AUX RELAY switches: Set the AUX RELAY switches as needed to obtain the desired function as shown on the following page.
6. EYE/EDGE switches: Set the EYE/EDGE switches as needed to obtain the desired OPEN or CLOSE functionality.
7. 1, 2, and 3 LEDs: LEDs indicating the status of the EYE/EDGE inputs. Also used to check the firmware version of the expansion board: a. Locate the 1, 2, and 3 LEDs on the expansion board. b. Disconnect AC/DC power to the main control board for 15 seconds. c. Connect power. The 1, 2, and 3 LEDs flash in sequence until the main control board firmware revision is displayed. When the green POWER LED glows solid the LED 1 flashes the version number, then stops, then the LED 2 flashes the revision number. (For example: For version 5.1 when the green POWER LED is solid the LED 1 flashes 5 times, then stop, then the LED 2 flashes once).
8. J6 and J7 inputs: Communication bus connects the main control board, expansion board, or relay adapter board. Also connects LiftMaster wireless edge receiver LMWEKITU.
9. Input LEDs: LEDs indicating the status of the SBC, OPN, CLS, and STP inputs.
10. Loop detector inputs: Inputs for the Plug-In Loop Detectors (Model LOOPDETLM).

CAUTION: To AVOID damaging the circuit board, relays or accessories, DO NOT connect more than 42 VDC (32 VAC) to the AUX relay contact terminal blocks.

AUXILLARY RELAYS

The expansion board and relay adapter board provide Normally Open (N.O.) and Normally Closed (N.C.) relay contacts to control external devices, for connection of Class 2, low voltage (42 VDC [34 VAC] max 5 Amps) power sources only. Function of relay contact activation determined by switch settings.

8 Earth Ground Rod

Use the proper earth ground rod for your local area. The ground wire must be a single, whole piece of wire. Never splice two wires for the ground wire. If you should cut the ground wire too short, break it, or destroy its integrity, replace it with a single wire length.

NOTE: If the operator is not grounded properly, the range of the remote controls is reduced and the operator is more susceptible to lightning and surge damage.

Diagram: Shows an earth ground rod being driven into the ground, with text "Check national and local codes for proper depth".

9 Power Wiring

A WARNING To reduce the risk of SEVERE INJURY or DEATH:

• ANY maintenance to the operator or in the area near the operator MUST NOT be performed until disconnecting the electrical power (AC or solar and battery) and locking-out the power via the operator power switch. Upon completion of maintenance the area MUST be cleared and secured, at that time the unit may be returned to service.
• Disconnect power at the fuse box BEFORE proceeding. Operator MUST be properly grounded and connected in accordance with national and local electrical codes.
• The operator should be on a separate fused line of adequate capacity.
• ALL electrical connections MUST be made by a qualified individual. DO NOT install ANY wiring or attempt to run the operator without consulting the wiring diagram.
• ALL power wiring should be on a dedicated circuit and well protected. The location of the power disconnect should be visible and clearly labeled.
• ALL power and control wiring MUST be run in separate conduit.

The operator can be wired for either 120 VAC or 240 VAC or a solar panel (not provided). Follow the directions according to your application. An optional Transformer Kit (Model 3PHCONV) can be used to change the input voltage (208/240/480/575 VAC) to an output voltage of 120 VAC (see "Accessories" on page 58). For dual gate applications, power has to be connected to each operator. Main power supply and control wiring MUST be run in separate conduits.
