Dual Gate Installations

Two operators can be used in dual gate installations. The operators communicate with each other through the 3-wire COMM LINK terminals.

When one operator activates, the COMM LINK connection signals the other operator to activate. Each operator functions independently, controlling its gate and monitoring its inputs and accessories.

A three-wire shielded conductor cable is required to connect two operators together for dual operation. Use Belden 8760 Twisted Pair Shielded Cable (or equivalent) only – P/N 2500-1982, per foot).

NOTE: The shield wire should be connected COMM LINK terminal “C” in both operators.

Three of the programming functions available are only used for dual gate installations:

Dual Gate Enable

Dual Gate Enable must be set for all dual gate installations.

Stagger Mode

The Stagger Mode function determines if the operator has a delayed open or a delayed close. In dual swing gate installations, typically one operator is programmed for delayed open, and the other operator is programmed for delayed close.

Stagger Delay Time

The Stagger Time sets the length of the delay for the Stagger Mode.

See Pages 12 & 14 for details on these three dual gate programming functions.

Gate Operation

Open Button

Opens the gate. If the Controller is programmed to stop opening the gate at mid-travel, a constant press of the OPEN button will override the Mid-travel Stop and completely open the gate. If the Auto Close Timer is set, it will be suspended until the OPEN button is released.

Close Button

Closes the gate if the gate is open. Also closes the gate if the gate is in the process of opening.

Stop Button

Stops the gate from opening or closing at any time.

Single Input

Opens the gate if it’s closed and closes the gate if it’s open (open-close programming option). Activating the input while the gate is moving will reverse the gate.

Can be programmed to stop the gate while the gate is moving (open-stop-close programming option).

Fire Department Input

Fully opens the gate when the input is activated. Overrides the Mid-travel Stop and Auto Close Timer (if either is programmed for the gate). The gate will lockout in the open position without sounding the alarm. Press the STOP button to release the lockout.

Open Input

Functions the same as the OPEN button.

Open Obstruction

While the gate opening, any open obstruction signal will cause the gate to stop, reverse a short distance, and then stop again. The Auto Close Timer will be disabled, and a renewed input will be required to start the gate again. Should the gate be restarted and the obstacle signal occur again prior to reaching a limit, the gate will stop again, lockout, and sound the emergency alarm.

Close Obstruction

Same as the open obstruction, but in the closing direction.

Reverse Input

If the reverse input is triggered while the gate is closing, the gate will reverse to the full open position. If the Auto Close Timer is set, when the reverse input is cleared, the gate will close when the Auto Close Timer expires.

Open Loop

Functions the same as the OPEN button.

Reverse Loop

Functions the same as the reverse input.

Shadow/Reset Loop

Only used with Swing Gates. Holds the gate fully open or fully closed while triggered. If open, the gate closes immediately when cleared.

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.
