SAFETY SUMMARY

It is important for everyone involved in the installation and operation of the LiftMaster model SL 1000-B1 Slide 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.

•Gate operators can present serious hazards to persons in the immediate area when not controlled in a safe manner. Choose one or more controls that together will allow complete control of the gate. Most importantly, the gate must be able to be stopped at all times in case of emergency, and the emergency control should be conveniently located, clearly marked and visible.

•All controls must be kept out of the reach of small children. Serious injury or death can result from children playing with the controls.

•All controls should be located so the person operating them can see the full area of gate movement.

•Gate operators and associated control equipment should be installed by qualified professional installers who should observe the following safe installation procedures:

1.Power should always be disconnected whenever installing, wiring or servicing a gate operator. Moving chains in gate operators can catch clothing or fingers and cause severe injury.

2.Installation of wiring should comply with local building and electrical codes.

3.All manual gate locks should be disabled to avoid damage to the gate or gate operator should the lock become engaged after the operator is installed.

4.All operator controls and safety equipment should be tested at the conclusion of installation to be sure they are functioning properly.

5.The operation of the gate controls and safety equipment should be reviewed with the owner and/or end user of the automated gate system. They should also be informed of the need to maintain control and safety equipment on a regular basis. Safety equipment should be checked monthly to ensure it is working properly. All installation manuals and safety information should be left with the owner.

6.Moving gates have pinch points and entrapment zones which can be extremely dangerous to pedestrians, especially small children.

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 SL 1000-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. The SL 1000-B1 is a flexible and reliable gate operator system, but the quality of service depends directly on the quality of installation. Please read these instructions carefully and study the applicable diagrams before planning your installation. In particular, understand any site characteristics that may affect the system installation.

WARNING

2.INSTALL PERMANENT WIRING. U.L. specifications require the SL 1000-B1 system to be permanently wired. Refer to your local wiring code for specific information.

WARNING: Damage caused by faulty wiring is not covered by warranty.

3.GROUND THE SYSTEM. The system contains parts which may be damaged by static discharge. A proper earth ground connected to the gate operator housing (see Figure 11) will significantly reduce the chances of damage or improper operation. The shielding in the cables specified for all remote sensors and controls should also be connected to earth ground at the controller end of the cable only.

To be effective, the ground connection must be made by running 12 awg copper wire to a good ground point (e.g., an electrical panel, a metallic cold water pipe that runs into the earth, or a grounding rod at least 10 feet in length that is driven into the earth) within 12 feet of the system. Even if you have a good earth ground, you should try to discharge any static before handling the circuit boards.

WARNING: Damage caused by static discharge and lightning is not covered by warranty.

4.PROVIDE POWER FROM A DEDICATED SOURCE. The outlet into which you connect the Gate Operator should be wired to its own circuit breaker. This will reduce the line noise introduced into system power and minimize the risk of having other equipment interrupt system operation. In a Master/Slave system, Master and Slave must each have separate circuits.

5.DO NOT OVERLOAD THE TERMINAL BLOCKS. The terminal blocks used in the gate operator are removable and the pins are soldered into the boards. To connect your wires, remove the "head" from the correct terminals and open the screws. Insert the wire into the correct opening on the front and tighten the screw until the wire is held firmly. When you have made all connections for a given "head", plug it back onto the pins designated for that terminal block.

Stranded wire must be between 16 and 24 awg. Solid wire must be between 18 and 24 awg. This is the total thickness measurement so, if you are putting two wires in, the combined thickness must fall within this range. NEVER try to insert more than two wires per terminal.

6.ENSURE GOOD CONNECTIONS. A light tug on the wire will tell you if the connection is secure. When reconnecting system components, make sure all pins are straight on chips, connectors, and terminal block heads.

7.READ THE MARKINGS CAREFULLY. The connection points are marked on the boards clearly. Before making any connection, be sure to read the marking and check it against the corresponding figure in these instructions so that you understand the connection you are making.

8.TRAIN YOUR CUSTOMERS THOROUGHLY. Although customer responsibility is limited to proper installation, the quality of service is determined by the care of system setup. Ensure that the customer has a copy of this manual to guide them. It will save you and them lots of inconvenience and aggravation later.

SITE PREPARATION

A. LOCATION AND LAYOUT

Figure 1. Front Drive.

Figure 2. Rear Drive.

Figure 3. Mid Drive.

•Figures 1-3 show typical single gate installations. For location and layout details of Bi-Parting, Bi-Parting Latch, Trap and Tandem gates, see B1 Series Master/Slave Systems (Doc. No. 6001378).

1.Always install the gate operator inside the fence line, never on the public side of the fence.

2.All manual controls and activating devices should be mounted at least 6 ft. away from the gate to provide safety.

3.Allow enough clearance around the gate and the gate operator for installation and service.

4.The gate operator can provide front and rear drive configuration (Figures 1 and 2), and mid drive can be used if the operator is post mounted and clearance is provided under the operator for the chain anchor on the gate (Figure 3).

5.Center idlers may be required on the Mid Drive and Rear Drive configurations to keep the chain from dragging on itself.

NOTE: Master links and tension adjusters are provided with the gate operator.

B. PAD AND MOUNT

Figure 4. Pad And Track Ribbon.

Figure 5. Bolt Down Pattern.

Figure 6. Conduit Entrance Areas.

1.The concrete pad must be sufficient to support the gate operator and the forces created by the moving gate. LiftMaster recommends a pad 20” wide by 30” long by 24” deep (Figure 4).

2.The operator must be level and parallel to the gate, so the pad should be level and about 4” above ground level 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. ½” x 3½ “ Red Head bolts are recommended (Figure 5).

4.Be sure to provide access for wiring conduits (Figure 6).

5.Track installation should be on concrete, not asphalt, and should be at least 10’’ wide and 6” deep.

6.A 6” gate overlap at the open end of the gate when closed should be provided.

7.A 30” gate overlap at closed end of the gate when closed should be provided.

NOTE: In Figure 6, shading indicates acceptable areas for conduit stub access.

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 (see B1 Series Master/Slave Systems Doc. No. 6001378).

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. Power for the loop detector can come from the auxiliary 115 VAC plugs in the gate operator or from the 24 VAC provided by the gate operator control board.

2.Conduit provisions should be made for the “loop” wire entrance to the loop detector.

3.The shelf space provided is approximately 4” x 10” x 5” high. Shelf space on systems without the Power Fail Operation Option is about 10" x 10" x 5".

NOTE: Optional LiftMaster-supplied loop detector add-on boards are available, both pre-installed and for installation in the field. See Part 4, Model SL 1000-B1 Options.

E. OTHER CONNECTIONS

Provisions should be made for conduit entrance into the gate operator for Master/Slave wiring and external activating devices such as key switches, telephone entry systems, etc.

D. SETTING GATE OPEN DIRECTION SWITCHES (S2, S3)

Figure 12. Gate Direction, Power Fail Option Switch Location.

The gate motion left to right is determined by looking at the gate from the gate operator side.

1.Gate opening direction is set by switch S2, located on the control board. The switch is sensed only on power up, so it should be set when the power is off.

2.Ensuring power is off, set switch S2 to the right for a Right Gate, or to the left for a Left Gate.

If the system was ordered with the Power Fail Operation option:

3.The power failure gate opening direction is set by switch S3, located next to switch S2 on the control board.
