Mid-Stop Limit Setup

This features provides a timing function to stop a door as it is traveling open at a Mid Stop position instead of the full open position. The door can then be moved to the full open position if desired by pressing the Open button. A single button input when the door is at the mid stop position will cause the door to begin moving in the close direction. The factory default is not set; the minimum run time to mid-stop limit is 6 seconds. After moving the door to the close position and temporarily setting the switches to the appropriate settings in the table, pressing STOP will remove the mid-stop limit setting.

Pressing OPEN will start the door open. When the door reaches the desired mid-stop position, press STOP.

Changing the dip-switch setting to any other setting will save the mid-stop limit position. Return the dip switches to the originally set Operating Mode setting (see section previous). Note: The door must move a sufficient distance to fully disengage the Reverse Cutout Limit nut from the Reverse Cutout Limit switch to set the mid-stop limit.

Auto Close Timer Setup

This feature allows for a modification of the amount of time between the door reaching either the Mid Stop or the Full Open position and automatically starting in the close direction. The Auto Close feature is only active when the operator is set to the T or TS Operating Mode (see section previous). The factory default is 30 seconds; the minimum time is 5 seconds; the maximum time is 5 minutes.

After moving the door to the close position and temporarily

setting the switches to the appropriate settings in the table, pressing STOP will clear and turn off the auto close timer. Every time OPEN is pressed, 5 seconds is added to the time. Changing the dip-switch settings to any other settings will save the new time. Return the dip switches to the originally set Operating Mode setting (see section previous).

Maximum Run Time Setup

This feature provides for a maximum amount of time the motor will be energized after an input is recognized. The factory default time is 30 seconds; the maximum time is 60 seconds. After moving the door to the close position and temporarily setting the switches to the appropriate settings in the table, pressing STOP will reset the time to the factory default setting. Pressing OPEN will start the door open. The run time will be recorded when the door reaches the open limit. To prevent nuisance problems, 0.75 seconds are added to this time. Pressing stop before the door reaches the open limit will stop the door and reset the time to the factory default.

Changing the dip-switch setting to any other setting will save the new time. Return the dip switches to the originally set Operating Mode setting (see section previous).

BRAKE ADJUSTMENT

The solenoid operated brake may require occasional adjustment. Adjustment is necessary if door tends to drift

downward after reaching the open limit. Follow the instructions below and use Figure 15 as a guide.

(1) Loosen shoe adjusting screw and bottom bracket arm of solenoid.

(2) Move tab until drum has a slight drag.

(3) Reverse drag slightly from tab and tighten shoe adjustment screw.

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.
