4      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 accu[...]

If any parts appear to be missing, contact dealer.  Temporarily plug the operator into 115 Volt outlet or extension cord.  Before beginning installation, test the gate operator by running the [...]

9 Installation continued...  Disconnect Power from the gate operator!  The tail end of the gate should extend approximately 24" beyond the edge of the driveway. If this is not the case, an extension tail will need to be added to the gate. This will give room for the gate operator. Make the extension tail 24" X 24" as shown. If [...]

10 Installation Continued...  If the steel mounting stand was used, simply bolt the gate operator to the stand. If the operator will be mounted to a concrete surface or pad, place the shortest edge of the operator 4" away from the edge of the driveway. Place the longer edge of the gate operator 2-1/2" away from the gate.  When the g[...]

11 Installation Continued...  Attach the gate bracket to the gate as shown using the round or square u-bolts for round or square gate frames respectively. Attach the chain to the gate brackets using the chain bolt and master link as shown. If necessary, the chain may be easily short- ened using a chain breaker. Adjust the height of the gate brac[...]

12 Alternate Inst allations  The rear mount installation is an excellent way to conceal the chain or opera- tor. The operator is placed in the extreme rear of the gate as shown and the chain never goes across the driveway. The chain only goes from the gate operator to a post or wall beside the driveway. Place shortest edge of the operator 3"[...]

13 Electrical  Make sure that power is OFF before making any electrical connections!  Be sure that all wiring is employed as required by local codes.  The operator is provided with two knockout holes on each side.

16 Wiring Diagrams, Button Controls z One button, two button and three button controls may be connected individually or together as shown below. Most button controls have a common "buss bar" which connects the common terminals of all buttons together so that only one common wire needs to be run back to the gate operator control board. If [...]

17 Fine T uning  The gate operator is designed to work differently while opening then while closing to optimize safety, so the direction of the operator will need to be set. Setting the operator direction is done by flipping the right/ left side switch located at the top of the circuit board. For a left side installation flip the switch to the l[...]

18 z Connect 115 Volts AC to each SL920 gate operator. Connect the four Master/Second wires from the master circuit board to the Second circuit board as shown below.
