CAUTION

IMPORTANT NOTE

BEFORE attempting to install, operate or maintain the operator, you MUST read and fully understand this manual and follow all safety instructions.

These instructions are intended to highlight certain safety related issues. These instructions are not intended to be comprehensive. Because each application is unique, it is the responsibility of the purchaser, designer, installer and end user to ensure that the total gate system is safe for its intended use.

CARTON INVENTORY

Before beginning your installation check that all components were supplied and received undamaged. Refer to list below for factory supplied parts.

NOTE: For the following instructions refer to Figures 1 & 2.

1. Layout the concrete pad as detailed in Figure 1.

IMPORTANT NOTE: The relative location of the operator to the fence and the gate is critical. Be sure that the measurements for operator mounting are taken from the centerline of the fence and of the gate hinge.

2.Locate electrical conduit, as required, prior to pouring concrete.

3.Pour concrete pad.

4.Bolt the (2) pad mount brackets to the bottom of the operator with the hardware provided.

5.Secure the operator to the pad. It is very important that the operator be level and square to the gate.

belt will turn and the control arm will move during some steps. Keep hands and tools out of operator and away from arm and drive shaft unless power is off or serious injury may occur.

CAUTION

Be aware that operator arm may start to move if a control device has been improperly connected. Keep hands and tools out of operator and away from arm and drive shaft.

4.Press CLOSE button (if installed) or connect terminals 4 & 5 on J1 terminal strip to cause the gate to close. The control arm should move in the close direction.

5.When control arm is pointed in approximate direction of gate bracket (on fully closed gate) press STOP button or release terminals to control arm.

NOTE: If control arm does not move far enough to point in proper direction, the close limit switch has been prematurely actuated. Turn power, loosen set screw on close limit cam and rotate nut away from close limit switch. Repeat steps 3 & 4 until control arm is pointed in correct direction.

6)If another authorized vehicle accesses the SAM system during the slide or swing gates closing cycle the SAM system will reopen the slide or swing gate. Once the slide or swing gate reaches the open position the barrier will then open to allow the vehicle to pass through the SAM system.

7)If no other authorized vehicles access the SAM system the swing or slide gate will close followed by the barrier.

DIAGNOSTICS (LEDS AND CODES)

There are three diagnostic LEDs. Two red LEDs (OL, CL) are indicators for the open and close limits. The LEDs are illuminated when the limit switch contacts are closed.

The third amber LED (DIA) is used to blink out diagnostic codes. The number is the count of the number of times the LED is on in an 8 second period. The LED is on for approximately 1/2 second and repeats every second until the number is reached. There will be a pause following each pulse cycle (1-6pulses) to differentiate between the different diagnostic codes.

NOTE: Normally the Hall Effect sensor does not need adjustment, but may go out of alignment due to shipping vibration or rough handling.

These operators use an internal entrapment protector system. This system consists of the GL control board, magnet, and Hall Effect sensor. It may become necessary to adjust the sensor for correct alignment. To do so please perform the following steps:

1.Loosen the two screws holding the hall bracket to the frame.

2.Adjust the hall effect bracket so that the hall effect board is: a. Parallel with the pulley.

b. .020" away from the pulley's magnet. Use a feeler gauge to measure the distance.

WARNING

To avoid SERIOUS PERSONAL INJURY or DEATH DISCONNECT electric power BEFORE adjusting hall effect.

3.Tighten screws to secure assembly.

4.Manually rotate pulley to ensure that each magnet clears the hall effect board.

If a magnet does not clear the board, re-adjustthe hall effect assembly accordingly.

All power must be disconnected from operator before maintenance can be performed.

All maintenance must be done by a LiftMaster dealer.

NOTES:

1.Severe or high cycle usage will require more frequent maintenance checks.

2.Inspection and service should always be performed anytime a malfunction is observed or suspected.

3.When servicing, please do some “house cleaning” of the operator and the area around the operator. Pick up any debris in the area. Clean the operator as needed.

4.It is suggested that while at the site voltage readings be taken at the operator. Using a Digital Voltmeter, verify that the incoming voltage to the operator is within ten percent of the operators rating.
