Construction and Operating Principles of TGK Series:
The TGK series transfers force via drive balls between the hub and drive plate. Torque can be adjusted during operation by changing air pressure. In case of overload, the drive balls disengage to protect the machine.

Clutch Mechanism:
To disconnect the drive source, stop air supply, allowing the built-in spring to disengage the drive balls. The system resets automatically upon air supply resumption.

Electrical Diagram and Basic Operation:
The system includes components like air filters, regulators, and solenoid valves. The motor operation is controlled via start/stop buttons and a selecting switch, with overload protection through limit switches.

Overview: The document provides detailed technical specifications and operational guidelines for a dual air control system and torque limiter devices. It includes information on air device configuration, electrical diagrams, and torque limiter models.

Air Device Configuration: The system includes components such as air filters, regulators, pressure gauges, spacers, solenoid valves, and silencers. The configuration is designed to manage air intake and supply to the TGK series, ensuring optimal operation through pressure regulation and solenoid valve control.

Basic Operation: The system operates by setting the selecting switch (SS1) to "AIR ON" and pressing the motor start button (PB1). The motor starts, and the TGK series enters the "CLUTCH ON" state. The limit switch ensures the motor continues to rotate even if the start button is released. If the pressure switch is off, the motor will not start. Overload detection is managed by limit switches, and the system can be turned off by switching SS1 to "AIR OFF."

Torque Limiter Specifications: The document details various models of torque limiters, including traditional friction types and those with sprockets. These devices are designed to protect machinery by slipping under overload conditions and automatically resetting once the overload is removed. The torque limiters are available in different sizes and configurations, with specific set torque ranges and dimensions.

Construction and Operating Principles: Torque limiters consist of components such as hubs, friction facings, disk springs, and adjustable nuts. They transmit torque through frictional force and slip when the operational torque exceeds the set limit. The document provides guidelines for selecting and setting torque limiters, including considerations for bore finishing and keyway specifications.

Key Features and Recommendations: The document emphasizes the ease of torque adjustment, automatic reset capabilities, and the availability of a wide variety of torque limiters for different transmission conditions. It also highlights the importance of maintaining friction facings free of contaminants and avoiding excessive speeds to prevent damage.

It includes detailed instructions on setting trip loads, installation procedures, and maintenance recommendations.

Specifications:

Model Numbers: TGA65, TGA150, TGA250, TGA350.
Max Set Load: 65, 150, 250, 350 kgf.
Components: Slide shaft, case, side plate, drive ball, plate, disk spring, hexagon socket head set screw, adjustable screw.
Dimensions and Load Capacity: Detailed in diagrams with specific measurements for each model.

Installation Guidelines:

Ensure the Axial Guard is installed on the driven side where overload is most likely.
Use adhesive for metal on threaded portions to prevent loosening.
Do not fix both the slide shaft and case side rigidly to avoid malfunction.
Apply grease to prevent interference between guide sleeve and guide shaft.

Setting Trip Load:

Use the No. of rotations indicator and angle indicator to set the trip load.
Loosen the hexagon socket head set screw before adjusting the load.
Perform a load trip test to ensure optimal settings.

Resetting Instructions:

Stop the machine and remove the cause of overload before resetting.
Reset automatically by reversing the load direction using low RPM.
Do not reset manually to avoid mechanical shock.

Safety Precautions:

Avoid using the Axial Guard with human transportation or lifting devices without necessary precautions.
Ensure the Axial Guard is not reset manually to prevent injury.

Auxiliary Parts and Stroke Limits:

Incorporate auxiliary parts like connecting shafts and guide sleeves for better functionality.
Ensure the Axial Guard does not exceed stroke limits to prevent loss of function.

Sensor Specifications:

Use TGA Sensors for overload detection.
Ensure proper wiring and installation to prevent damage.
Follow guidelines for connecting to power sources and preventing surge damage.

Load Residual Voltage Characteristics:

Low Power Voltage: When the power source voltage is below AC48V and load current is less than 10mA, the output residual voltage increases when the TGA Sensor is ON. When OFF, the load's residual voltage increases. Caution is advised when using voltage-operated loads like relays.
Small Load Current: If the load current is below 5mA, the residual voltage increases. To mitigate this, connect a breeder resistance in parallel with the load to ensure the load current exceeds 5mA, keeping the residual voltage below the load's return voltage. Recommended breeder resistances are 20kΩ at AC100V and 39kΩ at AC200V.
Large Inrush Current Loads: For loads with large inrush currents (1.8A and above), such as lamps or motors, use a relay to prevent deterioration or damage to the opening and closing elements.
