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
GATE SENSITIVITY: The SL920 Full Systems Capability circuit board has a
Vehicular Gate Operator Classes:
Class I - Residential Vehicular Gate Operator: A vehicular gate operator (or system) intended for use in a home of
Class II - Commercial/General Access Vehicular Gate Operator: A vehicular gate operator (or system) intended for use in a commercial location or building such as a multifamily housing unit (five or more single family units), hotel, garage, retail store, or other building servicing the general public.
Class III - Industrial/Limited Access Vehicular Gate Operator: A vehicular gate operator (or system) intended for use in an industrial location or building such as a factory or loading dock area or other locations not intended to service the general public.
Class IV - Restricted Access Vehicular Gate Operator: A vehicular gate operator (or system) intended for use in a guarded industrial location or building such as an airport security area or other restricted access location not servicing the general public, in which unauthorized access is prevented via supervision by security personnel.
Gate Operator model SL920 is intended for Vehicular Gate Operator Classes I, II, III, and IV.
Gate Inspection:
a)Install the gate operator only when:
1)The operator is appropriate for the construction of the gate and the usage Class of the gate,
2)All openings of a horizontal slide gate are guarded or screened from the bottom of the gate to a minimum of 4 ft. above the ground to prevent a
3)All exposed pinch points are eliminated or guarded, and
4)Guarding is supplied for exposed rollers.
b)The operator is intended for installation only on gates used for vehicles. Pedestrians must be supplied with a separate access opening.
c)The gate must be installed in a location so that enough clearance is supplied between the gate and adjacent structures then opening and closing to reduce the risk of entrapment.
d)The gate must be properly installed and work freely in both directions prior to the installation of the gate operator. Do not
