GENERAL INFORMATION

Three button control:
Momentary contact type for up, down and stop. Operator may be stopped in any position and door moved up or down from that position. Operator can be wired for constant pressure down when specified. Control circuit 24V. A.C. for user's protection.

Limit switches:
Screw type with oilite bronze cams and precision type micro switches for both up and down stopping of door positions. Easily adjustable without tools.

Reversing contactor:
Heavy duty type, STRUTHERS-DUNN or equal.

Electro mechanical stop:
This built-in door stop, load sensing device is standard equipment, if downward travelling door meets an obstruction, door will instantly stop. Easily accessible. Externally adjustable without tools. Operators with three phase motor can be made to instant reverse at no extra cost. This operator is also available with instant reverse mechanism for single phase motors. (OPTIONAL AT EXTRA COST)

Reduction system:
The power unit of this operator utilizes V belt and pulleys for primary reduction, roller chain and sprocket for secondary reduction to the output drive shaft. Rotating on high speed ballbearings and self-lubricating, self-aligning pillow block bearings for efficient long lasting, quiet operation. Door operating speed approx. 1.0ft. (.3m) per second.

Quick release door arm:
Quickly disengages operator from door (without tools) for manual operation in the event of power failure.

Dual trolley:
Cast aluminium alloy chain driven carriage, slides on dual heavy steel angle tracks, with full No. 65 push and pull roller chain, for smooth and quiet operation. In addition a roller spreader is provided to support trolley and prevent chains from rubbing.

Motor:
1/3 H.P. (.33hp), 1/2 H.P. (.5hp), or 3/4 H.P. (.75hp), 115V., or 230V., 1 phase - 208V., 440V. or 550V., 3 phase. This operator has an overload and under voltage protection.

Solenoid brake:
To prevent door from coasting and holding in any position.

Headroom required:
2-1/2" (62.5cm) from door's highest arc of travel.

Backroom:
4'7" (137.5cm) plus door height.

Finish:
Primed with rust-proof primer and spray painted in blue hammer tone enamel.



SPECIFICATIONS


Three button control:
Momentary contact type open, close, stop, full guarded standard duty, 600V. A.C. maximum, screw type terminals.

Motor control:
Heavy duty reversing contactor STRUTHERS-DUNN or equal. Two sets of three pole contactors on a common frame, mechanically interlocked to prevent simultaneous closure, clapper-type armature with three point suspension, auxiliary contacts, DPDT on each armature, coils 24V. A.C. amps resistive 120V. A.C. 15 amps, 240V. A.C. 10 amps, 550V. A.C. 5 amps. Motor 1 H.P. maximum. Terminals .250" (.625cm) quick connect, mechanical life 10 million cycles.

Electrical control cabinet:
Factory pre-wired, made from 14 ga. H.R. steel pre-formed enclosure, size 8" x 10" x 4-1/2" (20cm x 25cm x 11.25cm) with removable cover for easy service and maintenance. Mounted on unit chassis with 4 zinc plated steel bolts. Control circuit 24V. A.C. for user's protection.

Limit switches:
Screw type friction free oilite bronze cams grooved and lock guided in a formed galvanized steel plate. Cams are fitted on 5/8" x 10-3/4" (2.05cm x 26.88cm) C.R. threaded N/F steel shaft rotating on lubricated high speed ballbearings. Cams on their travel activate two limit switches to cut power of motor control, in both directions up or down. Operating forces on limit switches 4 oz. maximum, contact separation .020" (.05cm), pre-travel .250" (.625cm), termination .250" (.625cm) quick connect.

Reduction:
Power unit consists of one No. 4L V belt, one 1-1/2" (3.75cm) and one 9" (27.5cm) die cast aluminium alloy pulleys, balance for smooth operation for primary reduction. One 65B9 and one 65B23 steel sprockets with RC65 roller chain mounted on 5/8" (2.05cm) self-lubricating, self-aligning, high speed pillow block bearings for secondary reduction to the output drive shaft. All sprockets and pulleys pinned or keyed to shafting. Door operating speed approx. 1.0 ft. (.3m) per second.

Unit chassis:
Rugged frame assembly made from 2" x 2" x 1/8" (5cm x 5cm x .31cm) H.R. steel angles reinforced with steel plates, welded together for greater strength.

Heavy duty solenoid brake:
Consists of one 4" (10cm) diameter aluminium alloy disc mounted on keyed motor shaft, brake lined shoes with 360o exterior compressing force throw spring loaded mechanism. Brake disc stops door when electro-magnetic solenoid switch is released. Mounted on heavy duty steel plates protected in 14 ga. steel enclosure. Solenoid brake mechanism is self-adjusting type.

Trolley assembly:
Made from 2" x 2" x 1/8" (5cm x 5cm x .31cm) H.R. steel angles mounted together with 3/8" (9.5mm) H.R. steel rods. Cast aluminium alloy chain driven carriage, slides between the dual heavy steel angle track, with full No. 65 push and pull roller chain, for smoother friction free operation. In addition a roller spreader is provided to support trolley at centre and prevent chain from rubbing.

Electro-mechanical stop:
Standard equipment for this model, consists of a spring loaded sensing device incorporating a lever arm assembly with one 41B9 steel sprocket and a limit switch. Adjustment can be made externally by turning a thumb screw clockwise to decrease sensitivity.

Quick release door lifting arm:
1" x 3/8" (2.5cm x .93cm) H.R. steel bar bent to 90o adjustable to suit headroom with spring loaded hook, attached to aluminium door bracket. This arm quickly disengages operator from door without tools, for manual operation in the event of power failure.

Manual overload relay:
Protects operator from overload and under voltage current. Can be reset manually.
