Gate Arm Installation (Cont.)

Choosing Good Harmonics

Good harmonics are necessary to minimize wear and tear on the operator.The gate will have smoother starts and stops when the arm is installed with good harmonics. Figure 5 shows an example of good and bad arm harmonics.

Installing the Gate Arm on the Operator

The hex cap screws (see Figure 6) in the side of the crank assembly are shipped loose for placement on the operator drive shaft. Once in place, tighten these cap screws in place by applying 75 ft-lbs of torque. If it becomes necessary to remove the crank, you can do so by loosening these bolts. The arm can also be disconnected for manual operation of the gate by removing the disconnect pin.

Setting the Arm Lengths

Most installations will use the standard dimensions specifi ed. The dimensions shown in Figure 7 can be used to adjust and set the arm. If non-standard mounting is required, contact the factory for information.

Once the arm lengths have been determined, use clamps to temporarily attach the solid bars to their sections of rectangular tubing. If clamps are unavailable, you may also tack weld the parts in place. It is recommended that you check the arm for proper action and full gate travel before fully welding the parts together. REMOVE THE GATE ARM BEFORE WELDING! Apply Krylon® metallic gold spray paint or equivalent to touch up welds when fi nished.

CAUTION

DO NOT WELD THE GATE ARM WHILE IT IS ATTACHED TO THE OPERATOR! Connecting the welder’s ground to the operator’s frame will cause the arc welding current to pass through the operator parts, severely damaging or destroying the operator.

SWR, SWD, SWC specifications

Linear SWC (Single Wire Control), SWD (Single Wire Debug), and SWR (Single Wire Radio) are advanced communication protocols widely utilized in embedded systems and electronic applications. These protocols enhance the efficiency of data transmission, reduce the number of physical connections required, and simplify the design process for developers.

The main feature of Linear SWC is its ability to transmit control signals over a single wire, allowing for straightforward connectivity between microcontrollers and various peripherals. This approach minimizes the complexity of printed circuit boards (PCBs) and reduces the space needed for connections, making it ideal for compact designs. Linear SWC operates based on a master/slave architecture, where the master device initiates communication, and the slave devices respond.

SWD, primarily used for debugging embedded systems, is a two-pin interface that supports high-speed data transfer with minimal pin usage. Unlike traditional JTAG, SWD is simpler and more efficient, allowing developers to perform debugging and programming tasks with fewer resources. The SWD protocol offers features such as breakpoint management, memory read/write capabilities, and real-time variable monitoring, empowering developers to optimize their code and increase debugging efficiency.

SWR is focused on wireless communication, leveraging a single wire for transmitting radio signals. This technology is particularly advantageous in applications requiring minimal hardware while maintaining robust connectivity. SWR supports various modulation techniques and can operate in different frequency bands, making it versatile for various use cases. The single-wire approach reduces the complexity of antenna design and enhances the overall reliability of wireless communications in challenging environments.

One of the key characteristics shared by SWC, SWD, and SWR is their ability to reduce power consumption. By minimizing the number of connections and optimizing signal paths, these protocols significantly decrease the energy required for data transmission. Additionally, their compatibility with a wide range of microcontrollers and integrated circuits contributes to their widespread adoption in modern electronic designs.

In summary, Linear SWC, SWD, and SWR serve critical roles in the evolution of embedded systems, offering unique features, advanced technologies, and efficient characteristics. Their capability to simplify designs, reduce power consumption, and enhance overall communication quality makes them essential tools for engineers and developers in today's fast-paced technological landscape. As the demand for compact, efficient solutions grows, these protocols are poised to play an increasingly significant role in future innovations.
