Hello, I have a 220V 63A 2P ATS, similar to the one you explain, but it does not want to recognize a 120V power supply on the main line, only 220V gives the ready, the backup power supply works perfectly, but the main one does not work automatically since it does not give the ready or the second signal in the switch, could you tell me what I should do, the connection is fine, only that being 120V (1 phase + 1 neutral) it does not transfer, and I must close it manually and it only signals voltage, not ready-closed position, what should I do, would you help me?
My question is, the N side of my switch the UN light is on but the NON light is not and when i turn on my generator the R side both lights are on but on the N side only one and it hum like hell, what is the cause of this please.
I'm thinking of putting a relay between AR/AN connections wherein it will not switch back to Source A until Source B is still on. Is this possible? Thanks in advance.
Did you ever get an answer to this? I’d like to add an On-delay timer to mine as well. Yes it seems counterintuitive for an ATS setup, but I’m using the ATS for an inverter setup (even though a manufacturer advises against such). The situation with my setup is that it goes into a source switch loop when the batteries on the inverter is low and a sudden extra load is added while the batteries are still trying to get charged off the solar panels. The extra load causes the inverter to shut off and back on with the solar trying to charge it and the loop continues
EXPLAIN HOW TO USE BOTH ON DALAY TIMER & OFF DELAY TIMER TO THE SAME CIR CUIT. HOW TO SELECT THE SIZING OF SPARES TO ALL TYPES OF STARTING . ALSO MAIN CIRCUIT WIRES , SF UNITS. ALSO GIVE TIPS TO SELECT BOTH THE SF UNITS & MCB. BOTH THESE RATINGS ARE EQUAL OR NOT. PLEASE EXPLAIN.
