UL 325 Entrapment Protection Requirements

An entrapment zone is any location between a moving gate or exposed operator component and a counter-opposing edge or surface where entrapment is possible up to 6 feet above grade. This includes any gap between the bottom of the gate and the ground greater than 4 inches and less than 16 inches, and any gap between the pivot centerline and the end of a wall, pillar, or column exceeding 4 inches.

A minimum of two independent monitored entrapment protection devices is required at each entrapment zone. This operator includes one inherent (built-in) device; the installer must add at least one additional external device per entrapment zone. Acceptable device types are inherent, LiftMaster monitored external photoelectric sensors, and LiftMaster monitored external edge sensors.

Gate systems are made up of many component parts, and the operator is only one of them. Installers must account for the hazards of each individual application. Pedestrians must always be provided a separate access opening located so they never come in contact with the vehicular gate during its travel. Permanently mounted access controls must sit at least 6 feet from any moving gate part. A minimum of two warning signs must be installed so at least one is visible from each side of the gate.

Gates should be installed according to ASTM F2200. Gates must not fall over more than 45 degrees from vertical if detached from their hardware, must have smooth bottom edges with no protrusions exceeding 0.5 inches, and must not move under gravity alone if the operator is disconnected. The object covered by the gate in the open position must not exceed 4 inches measured from the pivot centerline, and clearance to any fixed object must be at least 16 inches unless entrapment protection is added.

The carton includes the gearmotor operator and cover (1/2 HP or 1 HP version), arm assembly, LiftMaster Monitored Retro-Reflective Photoelectric Sensor (Model LMRRUL), two keys, and two warning signs with warranty card. Documentation packet and hardware bag are not shown. Tools needed: 1/2" wrench for the cover screw, 5/16" and 3/4" wrench for 1/2" concrete anchors, phillips and flat head screwdrivers, and cable cutters and strippers.

Maximum Gate Weight/Length: CSW200501UL 600 lbs / 20 ft, CSW200101UL 1000 lbs / 22 ft. 90 Degree Travel Time: 20 seconds. Maximum Daily Cycle Rate: Continuous. Operating Temperature: -20°C to 60°C (-4°F to 140°F) without heater, -40°C to 60°C (-40°F to 140°F) with optional heater. Expansion Board: Provided.

Check national and local building codes before installation. Trench and install conduit before pouring the concrete pad; contact underground utility locating companies first, and use UL-approved conduit. Vehicle loops, while not required, are recommended for vehicles 14 feet or longer to keep the gate open while a vehicle blocks its path.

Before installing, confirm: the gate is level, the gate and post are plumb, the gate has a smooth bottom edge with no protrusions, any wheels are removed from the bottom of the gate, the gate does not drag across the ground, and the gate swings freely on its hinges.

A standard installation mounts the operator on its own concrete pad beside the gate post. An alternative to a concrete pad is to post mount the operator, see Accessories.

DO NOT run the operator until instructed. Refer to the standard installation chart to determine the concrete pad measurements and location; dimensions A through E are measured from the center of one pivot point to the center of another. If the gate is longer than 18 feet, use the alternate dimension chart. As a rule of thumb, the distance between the gate and the concrete pad is always 10 inches less than dimension D.

NOTE: There should only be a maximum of 4 inches from the center of the hinge to the edge of the post or column; if the distance is greater, entrapment protection for that area is required.

Check national and local building codes before installation. 1. Install the electrical conduit. 2. Pour a concrete pad, reinforced concrete recommended, at least 6 inches above the ground and deeper than the frost line, tall enough to avoid flooding. 3. Secure the operator to the concrete pad with appropriate fasteners. An alternative to a concrete pad is to post mount the operator, see Accessories.

It may be necessary to attach horizontal reinforcement to the gate before attaching the gate bracket. 1. Position the operator arm onto the output shaft so the pin slides into the slot. 2. Measure 46 inches along the gate length from the gate hinge center. 3. Measure 27.5 inches up from the concrete pad to the gate hinge position. 4. Confirm the operator arm is level and tack weld the gate bracket in place, using the set screws on the arm to temporarily hold it while measuring.

The arm length can be adjusted if necessary, keeping both sections proportional. Close the gate and measure the distance from the gate bracket to the output shaft center (distance E). Open the gate 90 degrees without letting the arms scissor, then measure both arm sections (C and D); the arm lengths are correct as long as C + D = E.

Once arm measurements are verified: 1. Weld the gate bracket to the gate. 2. Weld the short arm section. 3. Weld the long arm section. 4. Remove the set screws, completely welding around the outer tubing and bracket. 5. Adjust the nuts on the operator arm so it fits snug on the output shaft while still able to swivel (handle in a 90 degree position). 6. Tighten the handle by pushing it down and test that the arm does not slip on the output shaft.

WARNING: ALL gate operator systems REQUIRE two independent entrapment protection systems for each entrapment zone. Entrapment protection devices MUST be located to protect in BOTH the open and close gate cycles, between the moving gate and RIGID objects such as posts, walls, pillars, columns, or the operator itself.

Entrapment protection MUST be installed per UL 325 requirements: swing gate operators require the installation of the first external monitored entrapment protection device to function. Every installation is unique, so ensure ALL entrapment zones are protected. Test ALL entrapment protection devices after completing installation.

The control board has dedicated inputs: CLOSE EYES/INTERRUPT for photoelectric sensors in the close direction, CLOSE EDGE for edge sensors in the close direction, and OPEN EYES/EDGE for sensors in the open direction. The expansion board adds EYE ONLY and EYE/EDGE inputs that can be switched to either direction. Only one monitored device may be wired to each input.

Install the earth ground rod within 3 feet of the operator using a single, whole piece of wire, never spliced. Improper grounding reduces remote control range and increases susceptibility to lightning and surge damage.

For dual gate applications, power must be connected to each operator, with main power and control wiring always run in separate conduits. An optional Transformer Kit (Model 3PHCONV) converts 208/240/480/575 Vac input to a 120 Vac output. All control wiring to Class 2 circuits must be Power-Limited Circuit Cable Type CL2, CL2P, CL2R, or CL2X or better.

Power wiring: 1. Confirm the AC power switch on the operator is OFF. 2. Turn off AC power at the main breaker. 3. Run the AC power wires to the junction box on the operator. 4. Connect the green wire to the earth ground rod and AC ground. 5. Connect the white wire to NEUTRAL. 6. Connect the black wire to HOT. 7. Replace the junction box cover. 8-10. Turn AC power back on at the breaker, then turn on the AC power switch.

Dual gate communication is either wired or wireless, never both at once. Wireless setups are paired using the LEARN button: press it once on each operator to light the XMITTER LED, press again to light the NETWORK LED, then use the OPEN test button on the primary and CLOSE test button on the secondary to complete pairing.

Wired setups use a shielded twisted pair cable run between the Com Link terminals on each control board (Com Link A to Com Link A, Com Link B to Com Link B), with the cable shield grounded to the chassis of one operator. 22AWG cable is rated up to 200 feet; 18AWG up to 1000 feet, both at 30 Volt minimum.

The BIPART DELAY switch controls which gate opens first and closes first for overlapping decorative gates or solenoid locks (swing gate applications only; set to OFF for slide gates), and can also synchronize the close cycle when one gate travels farther than the other by setting both operators to ON.

Before installing the cover, set the handing and limits per the Adjustment section. The cover has two pieces: a rear cover and a front cover, with an access door for the reset switch that can be locked with the key.

1/2 HP: 1. Remove the operator arm by releasing the handle. 2. Place the rear cover over the operator and secure both sides. 3. Reattach the operator arm, making sure the pin fits the slot, and secure by pushing the handle down. 4. Place the operator arm cover over the arm. 5. Align the front cover with the back cover and secure both sides.

1 HP: Follows the same sequence, securing the front cover to the back cover in the final step.

Never increase force beyond the minimum needed to move the gate, and never use force to compensate for a binding or sticking gate. After any adjustment to force or travel limits, retest the safety reversal system: the gate must reverse on contact with an object.

Unlike the DC actuator-arm models, this operator uses mechanical limit switches adjusted with a limit nut or cam, combined with a "handing" setting (OPEN LEFT or OPEN RIGHT) that tells the control board which direction the gate swings.

Set the Handing

1. Make sure both OPEN LEFT and OPEN RIGHT LEDs are flashing; if not, press and hold both handing buttons until they flash and the operator beeps. 2. Press and release either the OPEN RIGHT or OPEN LEFT button depending on which direction the gate should open. OPEN RIGHT is used when the operator is installed on the right side of the driveway looking out of the property; OPEN LEFT is used when mounted on the left.

Set the Limits

1. Make sure the gate is closed. 2. Press the OPEN test button to open the gate. 3. Press STOP at the desired open position, then adjust the limit nut or cam to make contact with the open limit switch there. 4. Press the CLOSE test button to close the gate. 5. Press STOP at the desired close position, then adjust the limit nut or cam to make contact with the close limit switch there.

Set the Force and Run Distance

1. Press OPEN to open the gate. 2. Press and release both handing buttons together. 3. Press the handing button below the solid LED. 4. Run the operator through one full cycle using the test buttons; the initial force and run distance are set during this cycle.

The REVERSAL FORCE dial is set to minimum at the factory. Settings 1 through 3 are fixed force settings that will not adjust for gate wear or temperature changes; settings 4 through 10 automatically increase force to compensate for wear or temperature changes. If the gate stops short of a limit, increase force slightly clockwise.

After every adjustment, run the obstruction test: place an object between the open gate and a rigid structure, without triggering external entrapment devices. Run the gate in the close direction; it should stop and reverse on contact. If it doesn't, reduce force slightly counterclockwise. Repeat the test in the open direction.

The LEARN button is used for programming remotes and the wireless network. The diagnostics display shows the operator type ("SG20" for CSW200UL), firmware version, and diagnostic codes. The handing buttons (OPEN LEFT / OPEN RIGHT) determine which direction the gate opens and are also used to set the limits.

The BIPART DELAY dial is used only in dual gate applications where a maglock, solenoid lock, or decorative overlay requires one gate to close before the other, or to synchronize closing when one gate travels farther. The TIMER-TO-CLOSE (TTC) dial is factory set to OFF (0) and can be set from 0 to 180 seconds. The REVERSAL FORCE dial adjusts force (settings 1-3 fixed, 4-10 automatically compensate for wear). TEST buttons operate OPEN, STOP, and CLOSE, and are also used to view code history. Status LEDs indicate input power, timer state, gate motion, and accessory power overload.

The three button control station wires OPEN, CLOSE, and STOP with common, each overriding external safeties within line of sight. The Fire Department input and OPEN terminals act as a hard open, overriding external safeties.

The EXIT input is a soft open command for exit probes, telephone entry, or exit loop detectors. SHADOW holds the gate open at the limit when a loop is positioned under the gate. INTERRUPT holds the gate open and reverses a closing gate when a photoelectric sensor or loop sits outside the gate.

The CLOSE EYES/INTERRUPT, CLOSE EDGE, and OPEN EYES/EDGE terminals connect entrapment protection devices; only one monitored device per input. The locks output is a normally-closed relay contact for maglocks that activates before and during motor movement.

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.

The EXIT FAIL switch controls behavior when the plug-in EXIT loop detector faults. The AC FAIL switch is not used on this model since there is no battery backup. The ANTI-TAIL and QUICK CLOSE switches function the same as on the DC models. Auxiliary Relay settings include Open Limit Switch, Close Limit Switch, Gate Motion, Pre-Motion Delay, Power, Tamper, and Cycle Quantity Feedback, each set via a 3-position dipswitch combination, with an optional red/green light indicator wired to Aux Relay 1 and 2 showing gate state.

The expansion board also adds EYE ONLY and EYE/EDGE entrapment protection inputs, a Control Station (SBC, Open, Close, Stop with common), and Exit/Shadow/Interrupt loop inputs, each functioning the same as their main-board counterparts.

Up to 50 Security+ 2.0® remotes or KPW250 keypads, plus 2 keyless entries, can be stored in memory. To program a remote, press and release the LEARN button (the green XMITTER LED lights), then press the remote button to program within 30 seconds. Three programming options exist: single button as open only, single button as open/close/stop, or three separate buttons for open, close, and stop.

The LiftMaster Internet Gateway pairs through an online account at myliftmaster.com after connecting it to a router and powering it on, then pressing LEARN twice on the primary operator (or using the reset button sequence described in the manual).

Constant Pressure Override (CPO) is for use with KPW5 and KPW250 keypads, temporarily bypassing a faulted entrapment protection device using a valid 4-digit PIN plus holding the # key. The Gate Hold Open feature disables the Timer-to-Close and keeps the gate at the open limit using the same PIN entry method, or a programmed remote to restart the gate. To erase all remote codes: press LEARN, then press and hold it again for about 6 seconds until the XMITTER LED flashes.

Setup examples cover four site types: Residential, Commercial/General Access, Commercial, and Industrial, each with recommended settings for Quick Close, Anti-Tail, Bipart Delay, and Auxiliary Relay outputs, plus an optional heater accessory (Models HTRNB and HTR460 for 460V applications) for gearbox temperatures below -4°F.

For dual gate installations, the manual recommends setting all accessories and board configurations on the primary operator: the primary operator sets the Timer-to-Close dial and Bipart Delay switch, while the secondary operator has its Timer-to-Close off. Remote controls 1 to 50 program to the primary operator and 51 to 100 to the secondary. Expansion board settings (Quick Close, Anti-Tail) are typically ON for the primary and OFF for the secondary.

Check entrapment protection devices and the gate monthly. Inspect the manual disconnect, belt and pulley, accessories, electrical connections, chassis mounting bolts, and the operator every six months. Disconnect all power before servicing.

To view codes, the display shows the code sequence number followed by the code itself. The display cycles through up to 20 saved codes, most recent first. Press and release STOP to exit; the display also times out after two minutes. To reset the code history, press and hold STOP for six seconds until "Er" then "CL" alternate, then release.

The operator alarm sounds for up to 5 minutes if a contact sensor or the inherent force sensor detects an obstruction, incorrect installation, tight or broken hinges, a vehicle pushing the gate, a foreign object on the frame, or the gate hitting a curb, twice consecutively. Clear the obstruction and press reset to silence the alarm.
