What is the function of the PLC?

The PLC allows you to customize operational parameters like engine warm-up time and delay periods before transferring the load.

Troubleshooting

Generator fails to start during a power outage

Check the 8-pin connection cable for a secure fit and verify that the generator's internal start battery is charged.

ATS does not switch to generator power

Ensure the device is set to 'Auto' mode and check that the generator is producing the correct voltage output.

System keeps shutting down unexpectedly

Check if the emergency stop button was accidentally pressed or if there is a fault signal indicated on the PLC display.

Pros and Cons

Pros

  • Fully automated operation eliminates the need for manual generator startup during power failures
  • Programmable timing features protect the generator engine by allowing proper warm-up
  • Integrated battery charging ensures reliable starting performance over time
  • Robust steel housing provides durability for permanent wall-mounted installations

Cons

  • Limited to use with specific generators featuring an 8-pin ATS connector
  • Requires professional electrical installation for integration with home or facility circuits

Setup, Compatibility & Care

Installation should be performed by a qualified electrician to ensure safety and compliance with local electrical codes. 1. Mount the steel enclosure to a flat wall surface using the mounting holes. 2. Connect the ATS input to your generator using the provided 8-pin control cable. 3. Wire the mains input and generator load output to the respective terminals inside the unit. 4. Verify connections and toggle the switch to 'Auto'. To maintain the unit, keep the surrounding area free of dust and moisture, as the system is rated for 0-60% relative humidity. Regularly inspect the 8-pin cable for signs of wear and ensure the emergency stop button remains unobstructed.
