Function
2.1 ATS
If the default transfer modes cannot fulfill requirements, you can define a new ATS logic via CFC function to
meet the particular conditions and logics. Through CFC, you can do small logic changes of the existing transfer
modes.
When ATS is Ready, it becomes Unready with any blocking condition immediately; it will become Unready after
a delay (8939 Time Dealy to Un-Ready Status) with any Unready condition. When ATS is Unready, the signal
Ready is gone.
When one transfer mode starts, other transfer modes will be blocked. This action is to make sure that only one
mode of ATS can transfer the power supply during the same time.
After the transfer operation is finished, you can reset the ATS by manual reset and automatic reset. The reset
mode can be set via the parameter 0231 Manual Reset ATS. When it is set Yes, ATS will wait for the external
reset signal 17759 >Manual to restart or press the reset button (LED button) on the front panel after a transfer
operation. When it is set No, the ATS will automatically reset after a successful transfer operation. No matter
what the setting of 0231 Manual Reset ATS is, if the transfer operation fails, the ATS can only be reset by
manual.
When ATS is reset, the ATS will try to get Ready again.
