• Load changeover control for seamless power transfer.
• Manual start capability for generator operation.
• Protected Solid State (PSS) outputs for reliable control.
• Designed for front panel mounting.
• Front panel programming for easy configuration.
• LED indicators for status display.
• Configurable timers for customized operation sequences.
• Single/three phase mains (utility) sensing.
• Remote start input for external control.
• On-site module configuration to match specific user requirements.

3. Product Overview

4. Setup and Installation

4.1 Safety Precautions

• Ensure all power sources (mains and generator) are disconnected before installation or wiring.
• Installation should be performed by qualified personnel only.
• Wear appropriate personal protective equipment (PPE).

4.2 Mounting

The Controller 705 is designed for front panel mounting. Cut an appropriate opening in the control panel according to the dimensions provided in the product documentation. Secure the module using the supplied mounting clips or screws.

4.3 Wiring Connections

Refer to the detailed wiring diagram provided with your product documentation for specific connection points. Ensure all connections are secure and correctly terminated. Key connections include:

• Mains (utility) voltage sensing inputs.
• Generator voltage sensing inputs.
• Load output connections.
• Generator start/stop control outputs.
• Remote start input.
• DC power supply input.

4.4 Initial Configuration

The controller features front panel programming. Use the buttons and LED indicators on the front panel to set up parameters such as configurable timers (e.g., mains fail delay, generator cool-down time) and other operational settings as per your system requirements. Consult the programming guide in the full manual for detailed instructions.

5. Operating Instructions

5.1 Automatic Mode Operation

1. Mains Monitoring: The controller continuously monitors the incoming mains (utility) power supply.
2. Mains Failure Detection: If the mains power fails or falls outside acceptable limits for a pre-set delay, the controller detects the failure.
3. Generator Start Request: The controller sends a start request signal to the generator control unit.
4. Generator Running & Load Transfer: Once the generator starts and stabilizes, the controller transfers the electrical load from the mains to the generator.
5. Mains Return: When the mains power returns and stabilizes for a pre-set delay, the controller initiates the transfer of the load back to the mains supply.
6. Generator Shutdown: After the load is transferred back to the mains, the controller removes the generator start command, allowing the generator to enter its cool-down period and then shut down.

5.2 Manual Start

The controller supports manual generator starting. Refer to the front panel controls and the full product manual for instructions on how to initiate a manual start sequence, typically involving a dedicated button or switch.

5.3 LED Indicators

The front panel features LED indicators that provide visual feedback on the controller's status, including mains availability, generator status, load transfer position, and fault conditions. Consult the product documentation for a detailed explanation of each LED's function.

6. Maintenance

Regular maintenance ensures the longevity and reliable operation of your ATS controller.

• Periodic Inspection: Annually inspect all wiring connections for tightness and signs of corrosion.
• Cleaning: Keep the controller's exterior clean and free from dust and debris. Use a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Environmental Conditions: Ensure the operating environment remains within the specified temperature and humidity ranges to prevent damage.
• Functional Testing: Periodically test the automatic transfer function by simulating a mains power failure to confirm correct operation.

7. Troubleshooting

If you encounter issues with your Knowtek Generator ATS Controller 705, refer to the following common troubleshooting steps:

• Controller Not Powering On: Check the DC power supply connections and ensure the voltage is within the specified range. Verify fuses if applicable.
• Generator Not Starting on Mains Failure: Verify mains sensing inputs are correctly wired and receiving power. Check generator start signal output and generator control unit for issues. Ensure timers are correctly configured.
• Load Not Transferring: Check all load transfer wiring. Ensure both mains and generator power sources are stable and within acceptable parameters. Verify the transfer switch mechanism is functioning correctly.
• LED Indicators: Pay attention to any illuminated fault LEDs on the front panel. Consult the full manual for specific fault codes or indicator meanings.
• Configuration Issues: If the controller is behaving unexpectedly, review the programmed settings via the front panel to ensure they match your system requirements.

If problems persist after attempting these steps, contact technical support.
