What to do if my ABB Zenith ZTSCT engine does not start?
If the ABB Switch engine won't start, first check the engine start connections to ensure they are properly terminated. Also, verify that the generator is not in the OFF position; investigate why the Engine Control Switch might have been turned off.
Why does my ABB Zenith ZTSCT engine not stop?
If the ABB Switch engine continues to run, it could be due to several reasons. Check the U timer setting to ensure the timing cycle is complete. Also, verify that the engine start wires are correctly terminated. Finally, make sure the generator is not in MANUAL mode; it should be in AUTO.
What to do if ABB Switch ATS will not transfer to SOURCE 1?
If the ABB Switch ATS fails to transfer to SOURCE 1, check the DWTimer, TTimer, and DTTimer settings to ensure their timing cycles are complete. Also, ensure that the voltage or frequency of SOURCE 1 is within acceptable parameters by checking the utility and utility breakers. Lastly, verify that the power supply connector is properly plugged in.
How to fix ABB Zenith ZTSCT ATS that will not transfer to SOURCE 2?
If the ABB Switch ATS won't transfer to SOURCE 2, start by checking if the voltage or frequency of SOURCE 2 is within acceptable parameters. You should check the Engine Start Connections, Generator Breaker, Generator Output, and Engine Control Switch. Also, ensure the power supply connector is plugged in. Lastly, verify the WTimer setting to ensure the timing cycle is complete.
