The SW 2000-B1 contains the following features: • • • • • • • • • • • • • • • • • • • • • • • • Dynamic motor braking limits gate overtravel. Separated arm segment joints reduce the risk of injury to users. Alternate action OPEN/CLOSE inputs. Manual switch inputs override other commands. Adjustable reclose timer.
SAFETY SUMMARY It is important for everyone involved in the installation and operation of the LiftMaster model SW 2000-B1 Swing Gate Operator reads the following warnings. WARNING! • A vehicle gate is a large, heavy object that is moved by an electric motor. A moving gate can cause serious injury or death! The safety and well-being of others depends on the installation of a safe system. • Improper installation of a gate operator can result in a dangerous system.
BASIC INSTALLATION HINTS AND RULES PLEASE READ THIS SECTION CAREFULLY BEFORE BEGINNING YOUR INSTALLATION. The sections that follow contain detailed procedures for installation of a model SW 2000-B1 system. In addition to these specific procedures, there are a number of general hints and rules which will help ensure that your installation will be done correctly and efficiently. These are discussed below. 1. UNDERSTAND THE SYSTEM AND INSTALLATION SITE THOROUGHLY.
PART 1 SITE PREPARATION A. LOCATION AND LAYOUT Figure 1. Gate Operator Layout Options. • • NOTES Left Gate and Right Gate are determined by looking from inside the complex toward the street. Figure 1 shows a typical Bi-Parting gate in standard and compact installations. 1. Always install gate operators inside of the fence line, NEVER on the public side of the fence. 2. Mount all manual controls and activating devices at least 6 ft. away from the gate for safety. 3.
B. PAD AND MOUNT Figure 2. Pad and Mount. 1. The concrete pad must be sufficient to support the gate operator and the dynamic forces created by the moving gate. LiftMaster recommends a pad 24” wide by 27” long by 30” deep. 2. The operator must be level and parallel to the gate, so the pad should be level and about 4” above grade to prevent water entrance. 3. Four anchor bolts are required to secure the gate operator to the pad. The mounting holes in the gate operator are 5/8” in diameter.
C. POWER WIRING 1. Provide a separate conduit stub for the AC power. 2. Each gate operator requires a 115 VAC 20 AMP single phase circuit. NOTE: Master and Slave units each require separate circuits to prevent false overcurrent faults. 3. Be sure to pull a ground wire in the conduit for the connection to the gate operator. Do not rely on metallic conduit for earth ground. D. LOOP DETECTORS 1. The gate operator has a shelf that can support non-LiftMaster loop detector electronics.
PART 2 SYSTEM INSTALLATION A. MOUNTING GATE OPERATOR WARNING For safety reasons, the Power Fail Operation Option is shipped with the battery unconnnected to the system. Do not connect the battery until all other installation and alignment procedures have been completed. Failure to observe this warning may result in the Power Fail Operation Option moving the gate at unexpected moments. To avoid injury, always turn off the unit power switch before working on gate. 1.
C. RUNNING INPUT WIRING 1. Remove the plastic control box cover. 2. Run wires from input components and Master/Slave conduits into control box. 3. For Master/Slave wiring, refer to Part 3, Master/Slave Operation. WARNING Route but do not connect input wires at this time. If inputs are connected now, the gate operator may activate at random during installation, potentially injuring installation personnel. D. SETTING GATE OPEN DIRECTION SWITCHES S2 AND S3 Figure 4.
F. USING MANUAL CONTROLS Figure 5. Manual Controls, Location and Use. Use the manual controls on Manual Input Terminal TB2 (OPEN, CLOSE, and STOP, as shown in Figure 5), to move the gate for arm installation and making the limit cam adjustments. • To open the gate: connect the OPEN and STOP terminals to the COMMON terminal. • To close the gate: connect the CLOSE and STOP terminals to the COMMON terminal. • To stop the gate: disconnect the STOP terminal from the COMMON terminal.
G. GATE ARM INSTALLATION Figure 6. Gate Arm Installation. 1. Attach gate anchor to gate by welding or using hardware (not supplied). 2. Using manual controls, move the swing arm cap assembly until it points roughly to the anchor as shown in Figure 6. 3. Measure and cut the swing arm to length. Attach swing arm to swing arm cap assembly with gate stop on driveway side, using supplied hardware or by welding. WARNING: Installing gate stop on the wrong side will cause damage to the gate operator. 4.
H. SETTING LIMIT CAMS • The limit cams are adjusted by loosening the locking screws and rotating the cams. The cams rotate with the swing arm shaft, so small adjustments are magnified by the length of the gate. • The gate operator torque limiter allows the gate to be pushed or pulled a short distance (a few inches) only. Use manual controls to move the gate during limit cam adjustment.
2. SETTING LEFT GATE LIMIT CAMS Figure 8. Setting Left Gate Limit Cam. 1. Make sure that switch S2 is set to the "Right" position. 2. Turn on gate operator power switch. 3. Using manual OPEN and STOP, move the gate to its proper open limit position. 4. Loosen the locking screw on the bottom limit cam and turn the cam clockwise until it just barely closes the limit switch. 5. Retighten the limit cam locking screw. 6. Using manual CLOSE and STOP, move the gate to its proper closed limit position. 7.
I. GATE SENSITIVITY ADJUSTMENTS The gate operator monitors both average and peak motor current. When the gate encounters an obstruction, the gate operator senses the change in motor current and stops or reverses the gate. Three sensitivity adjustments must be set in the field: • Right gate motion (R78) • Left gate motion (R81) • Inrush current (R119) NOTES: The Overload adjustment (R71) is factory set. Do not adjust. Current flow varies with temperature.
2. RIGHT GATE (COUNTERCLOCKWISE OPEN) ADJUSTMENTS "Left Reverse" Adjustment (R81) 1. Initiate opening the gate. 2. Wait 4 to 5 seconds, then lightly "tug"against the edge of the gate to simulate an obstacle. 3. If the gate does not stop, reclose the gate and adjust the pot slightly counterclockwise. 4. Repeat steps 1-3 until the gate stops when tugged and has the desired sensitivity. "Right Reverse" Adjustment (R78) 1. Open the gate fully, then initiate closing the gate. 2.
J. SETTING GATE CONTROL SWITCH S1 AND RECLOSE TIMER POT R94 NOTE: For complete details on controls, indicators adjustments and inputs, see Appendix A. 1. GATE CONTROL SWITCH (S1) Figure 10. Gate Control Switch S1 Location. SLIDE ACTION (S1-1) TIMER (S1-2) RETRY (S1-3) ATG When used with ATG, this switch controls several gate operator features: Inside Interrupt Loop: four different modes are selectable: SLIDE and ATG OFF: Loop activation prevents the gate from opening or closing.
2. RECLOSE TIMER ENABLE (S1) AND SET (R94) Figure 11. Reclose Timer Enable and Adjustmment Location. The Reclose Timer pot (R94) is adjustable from 0 to 250 seconds. Turning the pot clockwise increases the reclose time. NOTE: Pot in figure is set to 0 seconds. 1. To enable the Timer, set switch S1-2 (TIMER) to the ON (right) position. 2. Turn the pot fully counterclockwise. 3. Open the gate. Gate should close almost immediately when it reaches the open limit. 4. Adjust the pot slightly clockwise. 5.
K. POWER FAIL OPERATION OPTION CONNECTION a) Power Fail Operation Option Connection CAUTION Perform the next step (battery hookup) with care. Interchanging battery wires temporarily opens the the resettabale fuse on gate operator board, disabling the power fail option. To ensure a safe installation, the gate operator is shipped with the battery partially disconnected from the Power Fail Option electronics.
L. CONNECTING INPUT WIRING Figure 12. Control Board Wiring. 1. Remove the plastic control box cover. See NOTES, next page, before proceeding. 2. Wire all external control devices to their connections on the control board as shown. See Appendix A for details on how each control input affects the gate operator. 3. Connect the Master/Slave interconnect cable (see Part 3).
NOTES 1. Disconnecting the STOP terminal from the COMMON terminal stops the gate and prevents all commands from having any effect. 2. Inside and Outside Interrupt Loops: M. • For safety and proper gate operation, gate(s) must open toward the Inside Interrupt loop. • For maximum safety, Inside and Outside Interrupt loops require separate loop detectors. • If only one loop detector is used, the Outside loop must also be connected to the Inside loop detector.
5. Maximum Retry Count 1. If you want the gate to resume operation automatically up to 2 times, 30 seconds after a Fault, set RETRY on switch S1 to ON. 2. If you do not want the gate to resume automatically after a Fault, set RETRY on switch S1 to OFF. 3. Give the opening gate a quick bump to generate a fault and verify retry operation. 6. Entry inputs 1.
10. Shadow Loop 1. Ensure the gate is fully closed (the close limit switch and Maglock LED’s will be ON). 2. Park a car, while it is running, on the Shadow Loop but clear of the Interrupt Loop. 3. Activate an open command and verify that the gate does not open CAUTION: If the gate begins to open, move the car immediately. 4. Remove the car from the Shadow Loop and verify that an open command opens the gate.
N. FINAL ASSEMBLY OF GATE OPERATOR Figure 13. Gate Operator Final Assembly. IMPORTANT SAFETY PROCEDURE ⇒ If switch S3 (Power Fail Open Direction switch) is set to OPEN the gate, cycle the gate to its fully open position before performing step 1. ⇒ If switch S3 (Power Fail Open Direction switch) is set to CLOSE the gate, cycle the gate to its fully closed position before performing step 1. 1. Turn off power to the gate operator at the circuit breaker and wait for one minute. 2.
PART 3 MASTER/SLAVE OPERATION A. WHAT IS MASTER/SLAVE OPERATION? The easy way to understand master/slave operation is by the computer terms "smart" and "dumb." • "Smart" machines are controlled by a computer or dedicated microprocessor, such as microwave ovens and new-style washing machines. • "Dumb" machines are controlled by simple electronic or physical mechanisms, like old-style washing machines with their cams and timers.
C. MASTER/SLAVE WIRING Connecting Master and Slave units is fast and easy: • Master/Slave connections are made through the SLAVE I/O terminal block (TB1), located at the top right corner of the gate operator controller board (see Figure 15, below). • Connect the Receive inputs (RECV1, RECV2) on each board to the Transmit inputs (XMIT1, XMIT2) on the other board.
D. MASTER/SLAVE SETUP PROCEDURE 1. Be sure to turn off both gate operator units. 2. Connect Master and Slave units as described and shown in paragraph C and Figure 15, above. 3. Set Switch S1 on Master and Slave units to your gate configuration according to the table, below. NOTES • If, before power up, the Master/Slave connection is broken, one of the units is turned off, or one of the controller boards malfunctions, the gates will operate in stand alone configuration.
E. MASTER/SLAVE INSTALLATION DETAILS 1. BI-PARTING GATE DETAILS The simple Bi-Parting Gate is typically used in low traffic residential sites due to its ease of use. The Bi-Parting configuration can consist of any combination of models SL 1000-B1 (slide gate), SW 2000B1 (swing gate) and BG 3000-B1 (barrier gate). SWITCH S1 SETTINGS: Slide:Unit Option Timer: Sys. Option Retry: Sys. Option ATG: Sys.
2. BI-PARTING LATCH GATE DETAILS The Bi-Parting Latch Gate is typically used in low traffic residential sites due to its ease of use and added security of magnetic locking. The Bi-Parting Latch configuration can consist of any combination of models SL 1000-B1 (slide gate), SW 2000-B1 (swing gate) and BG 3000-B1 (barrier gate). SWITCH S1 SETTINGS: Slide: Unit Option Timer: Sys. Option Retry: Sys. Option ATG: Sys.
3. TRAP GATE DETAILS The Trap gate is typically used in secured sites for screening incoming and/or outgoing traffic. In the Trap configuration, only one gate opens at a time, "trapping" the vehicle between gates. Due to its ease of use, Slide gates are most popular for the Trap configuration. The Trap configuration can consist of any LiftMaster model for Master, and a model SL 1000-B1 (slide gate) or BG 3000-B1 (barrier gate) for Slave. NOTE: The SW 2000-B1 (swing gate) may not be used for Slave.
There are 2 different ways to close the gate (entering or exiting): 1. Reclose Timer: When the Reclose Timer expires, gate closes automatically (Master or Slave). 2. Interrupt Loop; clearing the Inside Interrupt Loops cause the gates to close (Master or Slave). NOTE: To ensure gate closure, set Reclose Timer =ON in both Master and Slave INPUT CONNECTIONS: (for more details, refer to Part 2, Paragraph L, Connecting Input Wiring) • Master and Slave units require their own separate inputs.
4. TANDEM GATE DETAILS The Tandem gate is typically used in high traffic situations where some control of incoming and/or outgoing traffic is required. The outside gate is usually a less expensive, fast moving barrier gate (or light slide gate) which protects the more expensive and less mobile Slide or Swing inside gate. The outside gate does this by stopping the vehicle until the inside gate is completely open.
• A continuous FIRE input in either gate opens both gates and holds them open. • A continuous Manual STOP in either gate stops both gates. There are 2 different ways to close the gate after entering or exiting: 1. Reclose Timer: When the Reclose Timer expires, the gates close automatically (Master or Slave). 2. ATG and Interrupt Loop: When ATG is ON, clearing the Inside Interrupt Loop causes the gate to close (Slave unit only).
PART 4 MODEL SW 2000-B1 OPTIONS A. LIFTMASTER LOOP DETECTOR BOARDS The model SW 2000-B1 has connectors for four LiftMaster-supplied loop detector add-on boards. These boards interface with Interrupt, Shadow and Exit loop sensors, which simply plug into the control board. The add-on boards can be ordered pre-installed, or can be installed in existing model SW 2000-B1 units. B.

D. MAINTENANCE WARNING To avoid injury, always turn off the unit power switch before working on gate. Regularly performance of preventive maintenance is essential for reliable system operation because it corrects small problems before they turn into emergencies. LiftMaster recommends performing preventive maintenance every 6 to 12 months, depending upon the amount of gate usage.
PREVENTIVE MAINTENANCE INSTRUCTIONS Figure 20. Gate Operator Disassembly and Assembly. Gate Operator Serial Number: Power Fail Option: Yes One minute after a power outage the Power Fail Option: Opens Gate No Closes Gate ⇒ If switch S3 (Power Fail Open Direction switch) is set to open the gate, cycle the gate to its fully open position before performing step 1. ⇒ If switch S3 (Power Fail Open Direction switch) is set to close the gate, cycle the gate to its fully closed position before performing step 1.
The following table was provided to help you keep a record of the maintenance schedule. Write the inspection date in the left-hand box and check (✓ ) the boxes across as you perform your maintenance procedures.
APPENDIX A SYSTEM OPERATION REFERENCE CONTROLS, INDICATORS, INPUTS AND ADJUSTMENTS For control and indicator locations, refer to the figure below. For detailed explanations of the Gate Operator's various, controls, indicators, inputs and adjustments, refer to the pages that follow.
CONTROLS SWITCH S1 (OFF/ON DIP SWITCH) SLIDE ACTION (S1-1) TIMER When used with ATG, this switch controls several gate operator features: Inside Interrupt Loop: four different modes are selectable: SLIDE and ATG OFF: Loop activation prevents the gate from opening or closing. If gate is moving, Loop activation stops the gate. When the Loop clears, the gate resumes its course. SLIDE only ON: Loop activation prevents the gate from closing.
TIMER Indicates the Reclose Timer is running. Timer is set at pot R94. FAULT Indicates a fault in the system. See Fault List in Part 5, Troubleshooting and Maintenance. MAX RUN TIME Indicates the motor ran for more than 75 seconds without reaching a limit switch, and was stopped. Usually requires mechanical service. See Fault List in Part 5, Troubleshooting and Maintenance. REVERSE Indicates the peak motor current threshold was reached. See Fault List in Part 5, Troubleshooting and Maintenance.
SHADOW LOOP Activation prevents the gate from opening or closing so the gate won't hit a vehicle. If the gate is already moving, or if the gate is not fully opened or closed, this input has no effect. INSIDE/OUTSIDE INTERRUPT LOOP DETECTOR (TB16) INSIDE INTERRUPT LOOP with SLIDE "OFF" and ATG "ON" Gate fully open or closed: activation prevents the gate from moving. When the Interrupt loop clears, the gate begins closing. Gate opening or closing: activation halts the gate.
INS./OUTS. INT. SENSE / SHADOW SENSE / EXIT SENSE (TB12/TB13/TB14/TB15) INPUTS INSIDE Input from an Inside Interrupt loop provides the signal for an optional LiftMaster INTERRUPT loop detector add-on board. Operation is the same as the Interrupt Loop SENSE input, above. OUTSIDE Input from an Outside Interrupt loop provides the signal for an optional INTERRUPT LiftMaster loop detector add-on board. Operation is the same as the Interrupt SENSE Loop input, above.
CONNECTORS LIMIT SWITCH (J4) Connector for the left/right limit switch cable. BATTERY I/O (J11) Connector for use by the Power Fail Operation unit. PWR INPUT (J1) Connector for AC input power. MOTOR POWER (J3) 48 of 53 Connector for the motor cable. LOOP DETECTOR (J15) Connector for optional LiftMaster Outside Interrupt Loop detector add-on board. LOOP DETECTOR (J12) Connector for optional LiftMaster Inside Interrupt Loop detector addon board.
APPENDIX B PARALLEL GATE WIRING While it is strongly recommended that the Master/Slave function be used in any dual-unit installation, two LiftMaster model SW 2000-B1's may be parallel-wired as Bi-Parting gates only. NOTES: 1. When parallel wiring the RADIO INPUT terminals, do not connect the POWER output from one board to the POWER output on the other board. Failure to observe this will damage both controller boards. 2. Do not parallel wire the MAGLOCK terminals.
