Diagram 3-2-7-5
Refer to the following table 3-2-7-5.
Parameter
Value
Buzzer Status
can be Enable, Mute, Disable
Preferred Source
1 - The Preferred source is S1
2 - The Preferred source is S2
Synchronization Value
The value can be 10,15, or 20. If the phase difference
between S1 and S2 is less than this value degree, ATS
will regard two input sources as synchronous source
Delay Transfer Time on
Asynchronous
The value can be No delay, half cycle and one cycle.
When switching input source due to preferred source fail
if two input sources are not synchronous, the ATS will
add a period of delay time.
Input Voltage Acceptable
Range
The value can be between 12 and 20. for example ,the
range of input voltage window is +/-12% if this value is 12
Input Frequency Acceptable
Range
The value can be between 5 and 15. for example ,the
range of input frequency window is +/-15% if this value is
15
Nominal Voltage
The value can be 220,230 and 240. This is only available
for HV system
