Hardusb Posted July 3, 2023 Share Posted July 3, 2023 Hi, I am looking for a way to turn on an indicator light when my ATS Switch has switched over to Backup Power. I already have a Indicator Light on The Mains and Inverter input, but need a 3rd & 4th one to indicate that the switch is using the inverter or if its using the Mains power. Indicator 1: Mains Power Available Indicator 2: Inverter power Available Indicator 3: Mains Power is being used currently Indicator 4: Inverter Power is being used Thanks, Hardus Quote Link to comment Share on other sites More sharing options...

Virwat Posted July 5, 2023 Share Posted July 5, 2023 Is this the ATS 240 on a Sunsynk for the Neutral / earth bond or a transfer switch? If Auto transfer switch, give model and brand etc. Quote Link to comment Share on other sites More sharing options...
Hardusb Posted July 5, 2023 Author Share Posted July 5, 2023 Its for a normal separate ATS Switch. I have one built on a Relay and other on a ATS Switch. I attach pics of the ATS Switch and the relay version Schematics. Quote Link to comment Share on other sites More sharing options...
Virwat Posted July 5, 2023 Share Posted July 5, 2023 Hardus I am not exactly sure what you need to do. The ATS has got LED's for indication where the power comes from. Do you need indication at a different position, iow. not close to the ATS? Quote Link to comment Share on other sites More sharing options...
Hardusb Posted July 5, 2023 Author Share Posted July 5, 2023 The Big ATS Has 2 indicators to show if the power is present yes, the Relay ATS only has one led to show that power is present, but I need 2 more indicators to show which power is currently in use such as a light to show that eskom is in use and another that the Inverter is in use.

Hardusb Posted July 5, 2023 Author Share Posted July 5, 2023 (edited) Sorry, it's a thermal circuit breaker. 10A Updated drawing Attached. Edited July 5, 2023 by Hardusb Add Updated Drawing Quote Link to comment Share on other sites More sharing options...
Virwat Posted July 7, 2023 Share Posted July 7, 2023 To use an ordinary relay for indication purposes ONLY, here is a schematic. Relay is energized with grid present. But you must really stick to a proper ATS or a Change-over switch that the contacts break before they make. With a relay, you can't be sure about this. (Break before make) Quote Link to comment Share on other sites More sharing options...
Hardusb Posted July 7, 2023 Author Share Posted July 7, 2023 Thanks, will try tonight. These relay ATS Switches is only for light duty things such as between a tv / pc and generator / inverter, not for in a whole house configuration, but I can use this circuit in conjunction with a normal ATS Also in a DB for Indication purposes only. I dont understand what you mean by "contacts break before they make". Quote Link to comment Share on other sites More sharing options...
Virwat Posted July 7, 2023 Share Posted July 7, 2023 Your switch has 3 positions. Off position (o) - No power from any supply. Turn knob left from Off - i - power flow from supply. Turn knob right from Off - ii - power flow from different supply. Quote Link to comment Share on other sites More sharing options...
