Keep the remote control away from children. 3) Always keep people and objects away from the gate. NO ONE SHOULD CROSS THE PATH OF THE MOVING GATE. 4) Test the gate operator monthly. The gate MUST reverse on contact with a rigid object or stop when an object activates the non-contact sensors. After adjusting the force or the limit of travel, retest the gate operator. Failure to adjust and retest the gate operator properly can increase the risk of injury or death. 5) Use the emergency release only when the gate is not moving. 6) KEEP GATES PROPERLY MAINTAINED. Read the owner's manual. Have a qualified service person make repairs to gate hardware. 7) The entrance is for vehicles only. Pedestrians must use separate entrance. 8) SAVE THESE INSTRUCTIONS. 2 General Information General Information • ..........OVERALL DIMENSIONS: Height: 21" Length: 12" Width: 17" • ..........SHIPPING WEIGHT: 125 lbs. ..

General Information continued... • ..........CIRCUIT BOARD: The SL920 uses the Full Systems Capability circuit board, a powerful control system. This circuit board operates on 12 ~ 18 Volts and can deliver power to the motor through high power switching. The limit switch input terminals require the use of normally open type limit switches. These switches are used to accurately stop the gate operator in the open and closed positions. To safeguard the operator from damage that could result from limit switch or system protection failure, the Full Systems Capability circuit board has a built-in maximum run timer which will allow the operator to run for approximately 300 seconds and then shut off automatically. The Full Systems Capability circuit board has an adjustable gate sensitivity feature which will stop or reverse the gate if the gate is pushing harder than normal because of an obstruction. • ..........GATE SENSITIVITY: The SL920 Full Systems Capability circuit board has a built-in system protection feature which when adjusted properly will deliver only enough power to the motor to overcome the resistance of the gate. The amount of power that the circuit board will deliver can be adjusted for both directi...
