ATS controller reports "switch tripping alarm".
Check whether the load is overload.
Check whether load is short circuit.
Check whether impact current is too large.
Check whether tripping device is not working.
ATS controller reports "phase sequence is wrong".
Check whether phase sequence of voltage sampling is A, B and C.
For neutral position, ATS switch stops on the way.
Close delay is too short, open delay is too short.
Close delay is "0 s", switch has not action.
For two frame circuit breaker, can't switch.
Check whether there is electricity for circuit breaker close coil.
Check whether programmable output of controller is configured to "close output" or check whether fixed close output is wiring.
Check whether close delay setting of controller is greater than "3s".
Check if programmable output of controller is configured as "open output" and wiring.
Check whether one way close input and two way close input connect the circuit breaker auxiliary.
For AC contactor, 1 # and 2 # continuous switching.
Check controller close delay should be set to "0s" and ATS wiring.
ATS controller report "mandatory neutral" alarm.
Check whether programmable input port of controller is configured "mandatory neutral".
Check whether ATS switch has "neutral position", (if there is no neutral position , "mandatory neutral" is invalid).
ATS controller report "one way open failure" or "two way open failure".
Check whether the close delay of controller is set to "0s".
Check 1# and 2# of ATS open coil terminal and check whether programmable output of controller is configured with "1# switch open output and 2 # switch open output".
ATS switch for switching continuously
Check whether ATS switch 1# and 2# closing coil power cord is in good contact.
The ATS switch without breaking, the controller is configured to without neutral position.
ATS has showed, ATS switch but does not motion.
Check whether the programmable output of controller is configured with "1# switch open output and 2# switch open output".
Check whether programmable output is closed and its wiring.
Check whether ATS switch has neutral position.
Check 1# and 2# of ATS switch close coil power supply is normal.
Check whether 1# and 2# voltage sampling is normal.
Check if controller has an alarm option(such as: mandatory neutral,one close fault, two close fault).
For breaking is not mandatory ATS, check whether controller is configured programmable input port for " mandatory neutral".
ATS controller does not display.
Check DC power supply (without the suffix is a DC power supply, a B is DC, AC power supply are ).
