NOTICE

IT IS IMPORTANT THAT THIS INSTRUCTION

MANUAL BE READ AND UNDERSTOOD COMPLETELY BEFORE INSTALLATION OR OPERATION IS ATTEMPTED. IT IS INTENDED THAT THE INSTALLATION OF THIS UNIT WILL BE DONE ONLY BY PERSONS TRAINED AND QUALIFIED IN THE INSTALLATION, ADJUSTMENT AND SERVICE OF COMMERCIAL OVERHEAD DOORS AND DOOR OPERATORS AND BY QUALIFIED ELECTRICIANS.

NOTICE

THE IMPORTANT SAFEGUARDS AND

INSTRUCTIONS IN THIS MANUAL CANNOT COVER ALL POSSIBLE CONDITIONS AND SITUATIONS WHICH MAY OCCUR DURING ITS USE. IT MUST BE UNDERSTOOD THAT COMMON SENSE AND CAUTION MUST BE EXERCISED BY THE PERSON

(S)INSTAL- LING, MAINTAINING AND OPERATING THE EQUIPMENT DESCRIBED HEREIN. DO NOT

USE THIS EQUIPMENT FOR ANY OTHER THAN ITS INTENDED PURPOSE - OPERATING OVERHEAD COMMERCIAL VEHICULAR GARAGE DOORS.

STANDARD FEATURES:

Solid State Controls: The openers employ solid state technology with advanced standard features to provide for a complete commercial door operating system.

Switch Selectable Operating Modes: Six distinct base operation modes can be selected by resetting the switches on the motor control board: a standard Open, Close, Stop (B2, momentary button push); three constant pressure modes (C2, D1, and E2); two Timer to Close modes (T and TS). See page 15 for complete description of the modes.

Switch Selectable Characteristic Modes: Five different operating characteristics can be activated and/or modified through the switches on the motor control board: Delay On Reverse, Close Limit Delay, Mid Stop Travel, Timer to Close, Maximum Run Timer.

Limit Switches: Driven limit switches, easily adjusted over a wide range. The motor may be removed without affecting the limit switch adjustments

Manual Release: Permits manual operation of the door in the event of a power failure. The Model H-S is equipped with a chain hoist to aid in manual operation.

Control Circuit: Standard three button open, close and stop. 5 Volts DC.

Connections For Auxiliary Entrapment Protection Devices: For the ultimate in protection, terminals are provided to connect a Linear Corp. Photo-Beam System that consists of an emitter, Part No. 217792 and detector, Part No. 217800. This device when connected is a monitored photo-beam system. Additional

connection terminals for a Normally Open and Normally Closed reversing devices such as a reversing door edge or a three wire photo-beam are provided.

Constant Contact To Close: Standard operating mode. The operator can be converted to Momentary Contact To Close when the photo-beam as described above or one of the Miller Edge family of Door Edge devices as described on this page is properly installed on the door and connected to the operator. See Page 10 for the entrapment protection installation guide.

MODEL J-S & H-S OPERATOR APPLICATIONS:

Jackshaft operators are intended for commercial and industrial use to raise or lower sectional overhead doors by chain coupling or direct coupling to the door shaft. Jackshaft operators are suitable where all or part of the door remains in a vertical position when fully open such as doors with at least 18 inches of lift clearance or full vertical lift doors. Jackshaft operators may also be used with roll up service doors and grills when appropriately modified at the factory to obtain the correct speeds.

A jackhaft operator DOES NOT LOCK THE DOOR IN ITS CLOSED POSITION. However, because the cross- header shaft is prevented by the operator from turning, the torsion springs provide no assistance in lifting the door should an attempt be made to raise it manually.

The J & H Series jackshaft operators are used in the following applications:

- Continuous Duty, Medium Cycle Commercial installations only

-Indoor Use Only

-Up to 24 foot high doors with a maximum area of 480 square feet for 3/4 HP, 280 square feet for 1/2 HP and 200 square feet for 1/3 HP - maximum area slightly higher for lighter doors - consult factory

-To operate in Momentary Contact To Close mode and comply with the UL325 Entrapment Protection requirements effective Aug. 29, 2010, the door system must include one of the following (a, b, or c):

(a) Linear Corp. Photo-Beam System that consists of an emitter, Part No. 217792 and detector, Part No. 217800 for doors as described above up to 30 FT wide. See Page 10.

(b) Any Miller Edge ME, MT/MU, and CPT family of edges, with suffix T2, must be connected to the SM-102 Edge Module, Recognized by UL as per UL325 2010 on 08-29- 2010 for door as described above. See Page 10.

(c) A Vitector Fraba OSE 2-wire Photosystem as Recognized by UL as per UL325 2010 on 08-29-2010 for door as described above. See Page 10.

-The manufacturer of this operator strongly recommends installation of one of the entrapment protection device above and states that one is REQUIRED where any automatic, remote or manual control is used to activate the door.

OPTIONAL FEATURES:

Digital Radio Controls: Open, Close and Stop operation. Radio units are available to control up to 27 doors from one transmitter

Keyless Entry System: Connection terminals provided for hard wired or wireless keyless entry systems.

H-S, J-S specifications

Linear J-S and H-S are two prominent approaches in the realm of signal processing, particularly focusing on data compression and transmission efficiency. They provide robust methodologies for managing data in systems where bandwidth and storage are critical factors.

Linear J-S, or Linear Jordan-Space signal processing, is characterized by its ability to utilize linear transformations to represent signal variations with minimal loss of information. The main feature of this approach lies in its capacity to maintain high fidelity in signals while significantly reducing bandwidth consumption. By employing linear transformations, such as Fourier or wavelet transforms, Linear J-S efficiently captures the essential components of a signal. This methodology is particularly useful in scenarios involving audio and video data, where maintaining quality during compression is paramount.

One significant technology underpinning Linear J-S is the Fast Fourier Transform (FFT), which allows for rapid computation of the frequency components of a signal. This enables real-time processing and enhances the performance of systems that rely on rapid data transmission. Another critical aspect of Linear J-S is its adaptability to various data types, making it suitable for applications in telecommunications, multimedia, and even biomedical engineering.

On the other hand, Linear H-S, or Linear Harmonic-Skew signal processing, takes a different approach by focusing on harmonic analysis. This technique examines the harmonic content of signals to develop models that can accurately reconstruct the original data from its compressed form. The primary feature of Linear H-S is its robust handling of periodic signals, which allows for accurate representation even in the presence of noise.

Linear H-S technologies often leverage Adaptive Filter Theory and the Discrete Cosine Transform (DCT), which are effective in minimizing artifacts and preserving the integrity of the signal. This makes Linear H-S highly applicable in areas like image processing, where it plays a critical role in JPEG compression, ensuring that the visual quality remains intact without unnecessarily large file sizes.

Both Linear J-S and H-S employ algorithms designed for optimal reconstruction of signals from their compressed forms, emphasizing the need for low latency in applications where speed is crucial. They each have their unique characteristics, making them suitable for different types of signals and applications. While Linear J-S excels in the realm of audio and complex data types, Linear H-S proves to be invaluable in scenarios involving repetitive patterns and periodic signals.

In conclusion, Linear J-S and H-S represent two sophisticated methodologies in signal processing, each with distinct features and technologies designed to optimize data compression while faithfully preserving signal quality. Their applications span across various industries, showcasing their importance in contemporary data communication and multimedia systems.
