Following installation, the operator MUST be tested and respond correctly to all controls as specified on the wiring diagram. KEEP personnel and equipment clear of the area beneath the door when performing the tests. When testing the 3 -button wall station, first observe that each button operates the door in the direction indicated and that the STOP button performs that function. With the door stopped at its full open position, the OPEN button should be inoperative. This should be verified and, likewise, the CLOSE button should be inoperative with the door fully closed.

Certain operator control circuits use only a single button or a two button control station and may be designed to function differently than the more common three-button circuit described above. Test the controls in accordance with the description of operation as indicated on the wiring diagram and as selected according to the instructions on page 15,

“OPERATING MODES”.

Observe the door when traveling in each direction for smoothness of operation. Test the setting of the clutch by restraining the door by hand. The clutch should slip. Re-check the limit settings. The door should close tightly at the floor without excessive impact. Likewise, it should fully clear the door opening without the carrier striking the stops on the rail.

The J-S & H-S series operators are equipped with a reversing circuit and to allow for Momentary Close Contact operation an approved entrapment protection device as described on Page 3 needs to be properly installed and connected to the operator. To test it for proper reversal, place an object beneath the leading edge of the door. The door should reverse when it comes into contact with the object provided the height of the object exceeds the cut out point built into the close limit switch (approximately four inches).

CAUTION

DO NOT STAND UNDER DOOR TO TEST REVERSING FEATURE USE A CORRUGATED BOX

OR OTHER SIMILAR OBJECT

If the operator is equipped with other means of control, such as additional 3 button stations or radio controls, each of these should be tested separately for proper operation.

To test the manual disconnect first move the door to the fully closed position. Then disconnect the power to the operator. Manual door operation mode should engage when the release chain is pulled. The door can then be manually opened or closed by physically moving the door (Model J-S) or using the hoist chain (Model H-S). If it is difficult to engage and/or the jackshaft to doorshaft chain appears to be under compression, reset the CLOSE limit slightly to reduce the door travel in the close direction.

WARNING

ALWAYS DISCONNECT POWER TO THE OPERATOR BEFORE SERVICING, CONNECTING ACCESSORY DEVICES OR MAKING ADJUSTMENTS.

MAINTENANCE

Normally, very little maintenance is required. A monthly visual inspection must be made for loose or missing hardware and for excessive slack in the V-Belt and jackshaft chain. The clutch must be tested periodically and adjustments made if necessary (see page 18). The brake is adjusted at the factory and will need periodic adjustment for wear. When adjustment becomes necessary see Figure 15 on page 17 for the adjustment procedure.

Test the reversing edge circuit at least once a month by permitting the door to contact an obstruction while closing.

CAUTION

DO NOT STAND UNDER DOOR TO TEST REVERSING

EDGE - USE A CORRUGATED BOX

OR OTHER SIMILAR OBJECT

Lubrication of the operator is not required. It is important, for trouble free service from the operator, that the door be kept free from binding, properly counter balanced and periodically lubricated. An annual inspection of the door by a qualified overhead door professional is recommended.

Warning: Repairs and adjustments to the door and operator should be performed only by someone qualified to service commercial overhead doors and operators.

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.
