Preventative Maintenance

WARNING

Always disconnect power from operator before servicing. Keep clear of gate during operation.

General

Linear gate operators are designed for many years of trouble-free operation and, under recommended operating conditions, will require only minimal maintenance. To ensure that a unit is ready for operation at all times, and to preclude serious damage or failure, inspect the unit systematically. Proper adjustments and lubrication should be made as recommended.

Lubrication

Bearings — For models which have pillow block style bearings with grease fi ttings, lubricate at least twice a year with a lithium complex based, petroleum oil NLGI 2 rated grease. Oilite and precision sealed bearings do not require additional lubrication.

Motor — Motors have sealed ball bearings and do not require further lubrication. If bearing noise develops after several years of operation, bearings should be replaced by a motor repair company, or the motor should be replaced if necessary.

Swing Gate Arm — Check all bolts for proper tension and tighten if necessary. Make sure the arm folds overextends itself slightly against the overtravel stop to reduce the chance that the gate can be backdriven open. Adjust the close limit slightly if additional travel is required. Lightly lubricate all pivot points with a light machine oil.

6-Month Preventative Maintenance

1.For operators which utilize torque limiting clutches, check for proper tightness. If there appears to be dust from wear on the pads, inspect the pads and replace if necessary. If the clutch cannot be adjusted tightly enough to move the gate without slipping, the pads must be replaced.

2.For operators with V-belts, inspect for wear and replace as necessary. Check for proper tension and adjust if required. Check all pulley setscrews for tightness and tighten if necessary.

3.For operators with internal chain drives, inspect chain and sprockets for wear and replace if necessary. Check for proper tension and alignment, and adjust if required. Check all hub sprocket setscrews and tighten if required.

4.Check limit switches and limit actuators (cams, limit nuts, etc.) for wear and replace as required. In rotary limit switch assemblies, wipe the limit shaft clean and apply a light coating of dry lubricant.

5.Inspect all nuts and bolts for proper tightness and tighten as necessary.

6.Check all reversing devices for proper function. Inspect all contact edges for wear and replace if required. Check photoeyes for proper alignment and function.

7. Check current sensing for proper adjustment when

fi nished with inspection and maintenance.

8.Inspect the installation area. Are all the warning signs intact and visible? If they are missing or need replaced, contact Linear. Be sure there are no control stations mounted within reach of the gate. Review safety literature with the customer and advise them to remove any such stations found.

FCC Notice

This device complies with FCC Rules Part 15 and Industry Canada Rules & Regulations. Operation is subject to the following two conditions: (1) This device may not cause harmful interference and (2) this device must accept any interference received, including interference that may cause undesired operation.

For all gate operators, you must inspect the gate for proper operation. The gate should move easily without binding through its entire travel. If the gate does bind, adjust or fix as required. Failure to keep the gate in good working condition will have adverse effects on 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.
