GENERAL INFORMATION

DOORLEC'S most powerful sliding gate operator for industrial installation. The model SGOH is specially designed for sliding gates, overhead, cantilever or roller V track type up to 85 ft. (25.9m) wide and weighing up to 2,100 lbs (952.5 kg). Heavy gauge steel base for concrete pad mounting or post mounting (optional, at extra cost) with 500 watts thermostatically controlled heater and weather-resistant lockable cover, removable for easy service and maintenance. Will accept, when specified, any optional equipment for fully-automatic operation (see catalogue # E113)

Reduction:
Worm-gear reducer, single stage, running in oil bath, 40:1 ratio, C flange design, cast iron alloy housing, No. 50 roller-chain and sprockets from operator drive shaft to gate brackets. Gate speed: 7" (18cm) per second approximately.

Adjustable Torque Limiter:
Will protect gate and operator in case of obstruction. (Optional at extra cost).

Reversing Contactor:
Heavy-duty type.

Three-Button Control:
Momentary-contact type for open, close, stop. Operator may be stopped in any position and gate opened or closed from that position. Close button can be wired for constant pressure when specified. Control circuit: 24V. A.C. for user's protection.

Safety Interlock:
Electrical interlock switch automatically cuts power of operator control when hand-crank is in operation.

Selenoid Brake:
To secure locking of gate in closed position.

Manual-Overload Relay:
For overcurrent and under-voltage protection. Manual reset.

Motor:
3/4 H.P. (560W), 1 H.P. (746W), 1-1/2 H.P. (1119W) or 2 H.P. (1493W). 120V. or 240V. single phase, 208V., 230V., 416V., 460V. or 600V. three phase.
2 H.P. (1492W) not recommended in single-phase motors.

Finish:
Primed with rust-proof primer and spray-painted in blue hammertone baked enamel.



SPECIFICATIONS


Motor Control:
Heavy-duty reversing contactor, two sets of three-pole contacts on a common frame, mechanically interlocked to prevent simultaneous closure. Clapper type armature with three-point suspension, auxiliary contacts SPDT or DPDT (as required) on each armature. Coils: 24V. A.C. Load contact amps: resistive: 15 amps @ 120V. A.C., 10 amps @ 240V. A.C., 5 amps @ 600V. A.C.; Inductive: 2 H.P. (1492W) max. Terminals: .25" (.6cm) quick connect. Mechanical life: over 10 million cycles.

Reduction:
Worm-gear reducer, single stage, running in an oil bath, with 40:1 ratio, C flange design, cast iron-alloy housing. Hardened and ground steel worm and alloy bronze worm-gear for greater wear life. High-speed taper roller bearings, double-lip, spring-loaded seals to keep lubricant in and dirt out. Alloy steel shafting hardened and ground for greater strength. Input RPM 1750, max. 2 H.P. (1492W). Output torque: 1380 in.lbs (1590cm. Kg). Overhang load: 1100 lbs (500kg). Output shaft: 1" (2.54cm) D. Speed: 44 RPM. Gate speed: 7" (18cm) per second approx.

Unit Chassis:
Heavy steel channel-frame assembly reinforced with steel gusset plates, bolted together for greater strength.

Limit Switches:
Rotary-type, friction-free, oilite bronze cams, grooved and lock-guided in a spring-loaded, formed galvanized steel plate. Cams are fitted on 5/8" x 10-3/4" (1.59cm x 26.88cm) C.R. steel shaft, rotating on lubricated high-speed ball bearings. Cams on their preset travel, activate the micro switches to cut power of motor control in both open and close directions. Operating force on limit-switches: 4oz. (113.4g) maximum. Contact separation: .020" (.05cm). Terminations: .250" (.625cm) quick connect.

Electrical Control Cabinet:
Factory pre-wired, made of sheet metal, construction of suitable rigidity designed to meet EEMAC and CSA classifications type 12. Size 8" x 16" x 5" (20cm x 41cm x 13cm) with removable cover for easy service and maintenance. Mounted to unit chassis with four zinc-plated steel bolts.

Heater:
Thermostatically-controlled 500 watts heater is provided to prevent freezing of oil in reducer and eliminate humidity on electrical components.

Torque-Limiter:
Will protect gate and operator in case of obstruction, limits will not go out of adjustment when torque limiter is activated. Torque limiter consists of a steel hub with two 4" (10.2cm) diameter clutch plates, a 50B23 sprocket, two 4" (10.2cm) diameter non-flammable friction-discs and spring-washer with adjustable pressure cup. Adjustable holding force from 25 lbs. To 1500 lbs. (11.4 to 682 kg) must be adjusted in the field, as required, depending on gate weight. (Optional at extra cost).

Manuel Crank:
With safety electrical interlock. When manual mode lever is pulled, the operator brake assembly is released, permitting manual-crank operation of gate without having to remove the main drive chain. When manual-crank is in operation a switch cuts the 24V. control circuit of operator automatically. This safety electrical interlock will protect operator and gate when power is restored and push-button is pressed accidentally.

Power Head Base:
Made of 11 ga C.R. steel, reinforced with steel braces and welded together for greater strength. Lockable cover for total weatherproof assembly. The SGOH operator is primarily designed for concrete base mounting installation. Can be modified to suit post-mounting when specified. (Optional at extra cost).

Motor:
Rated for continuous duty (capacitor starting on single-phase models) 3/4 H.P. (560W), 1 H.P. (746W), 1-1/2 H.P. (1119W) or 2 H.P. (1493W), 120V. or 240V. single-phase, 208V., up to 600V. three-phase, 1725RPM. Ball bearings permanently lubricated. Frame : rigid type 56C. Shaft: 5/8" (1.56cm) or 7/8" (2.22cm) diameter. 2 H.P. (1493W) not recommended in single-phase motors.

Unit factory pre-wired, colour-coded and tagged.
Wiring diagrams, installation instructions are enclosed with each operator.
Operator is pre-run and tested before shipment.


NOTE

Rated for continuous duty (capacitor starting on single-phase models) 3/4 H.P. (560W), and 1 H.P. (746W) 120V. or 240V. single-phase, 208V., 230V., 416V., 460V. or 600V. three-phase. (Single-phase voltage for 1 H.P. (746W) motor not recommended). 1725 RPM, ball bearings permanently lubricated. Frame : rigid type 56. Shaft: 5/8" (1.56cm) diameter. Other voltages available on request.

This locking mechanism is of unique design. Upon closing of gate, the locking-bolt, mounted on the leading edge of gate, enters the lock-housing which is stationary-mounted on the gate post, causing automatic snap-lock action. When the electric operator is energized a solenoid actuated plunger simultaneously releases the locking bolt and permits the gate to be opened. A key lock is provided to manually release locking mechanism in the event of power failure. The Doorlec gate lock is shipped as shown above, however, mounting brackets must be fabricated to suit post dimension.

Specify diameter of stationary post when ordering.

Operating voltages available: 120V., 208/230V., 460V., 550V.
