WARNING

RISK OF ENTRAPMENT THAT MAY RESULT IN SERIOUS PERSONAL INJURY OR DEATH.

DISCONNECT POWER TO THE OPENER

BEFORE SERVICING OR MAKING

ADJUSTMENTS. ENSURE DOORWAY IS

CLEAR BEFORE STARTING TESTING OF UNIT.

REQUIRED TO THE DOOR, DOOR SPRINGS OR DOOR OPERATOR MUST BE PREFORMED BY A QUALIFIED PROFESSIONAL DOOR INSTALLER.

The clutch pad will wear during normal operation and should be replaced when it becomes difficult or impossible to sufficiently tighten the clutch to obtain smooth operation of the door when it is in good working condition. To replace the clutch pad, first loosen the motor mounting bolts and remove the V-belt then the clutch adjusting nuts, spring and clutch pulley. Check condition of V-belt before reassembly and replace if required. After reassembly, adjust clutch as described above.

CAUTION

 

ALWAYS DISCONNECT POWER TO

 

OPERATOR BEFORE SERVICING OR MAKING

 

ADJUSTMENTS

107101

The clutch serves to protect the door, the electric operator and other equipment from undue stress or damage caused by starting forces and/or an obstruction to the door. It should be set no tighter than is necessary to smoothly and consistently move the door throughout its full range of travel. When properly set, it will slip freely if the door should encounter an obstruction, and it should be possible to stop the travel of the door by hand.

WARNING: Before adjustment remove power to the operator.

To adjust the clutch, loosen the jamb nut, and turn the adjusting nut, as shown at right Make adjustments in 1/4 turn increments. Always re-tighten the jamb nut before running the operator to prevent clutch from changing its setting.

CAUTION

NEVER COMPRESS CLUTCH SPRING BEYOND

POINT LIMITED BY THE DESIGN OF THE OPERATOR OR REPLACE IT WITH A HEAVIER SPRING

Due to changing conditions of the door and normal wear, it may be necessary to occasionally readjust the clutch to obtain dependable operation.

WARNING: BEFORE DOING SO BE CERTAIN THAT THE DOOR IS IN GOOD WORKING CONDITION, PROPERLY COUNTERBALANCED AND THAT THE CLUTCH IS NOT SLIPPING BECAUSE OF LOOSE OR MISSING HARDWARE, BINDING IN THE TRACK, RUBBING AGAINST THE DOOR STOPS OR DEFECTIVE OR MISADJUSTED SPRINGS. ANY SERVICE

WARNING

IMPROPER ADJUSTMENT OF CLUTCH SETTING COULD CAUSE ENTRAPMENT, INJURY OR DEATH.

SET CLUTCH ADJUSTMENT FOR JUST ENOUGH FORCE TO OPERATE THE DOOR RELIABLY, BUT NO STRONGER. Contact a service professional to correct any binding, sticking or other door problems. DO NOT OVER-ADJUST CLUTCH SETTING TO COMPENSATE FOR A POORLY WORKING DOOR.

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.
