A – AMF (Auto Mains Failure) settings 10.4
A01
Emergency Start Delay
Units:
seconds [s]
Step:
1 s
Range:
0 – 600 s
Default value:
5
Delay between the mains failure and the automatic start of the gen-set to an AMF operation.
A02
Mains Return Delay
Units:
seconds [s]
Step:
1 s
Range:
1 – 3600 s
Default value:
20 s
This is a "mains stabilization" time. Timer begins when mains returns. If the mains are continuously
healthy for this period, the controller will finish the AMF operation.
A03
Mains Overvoltage
Units:
percentage [%]
Step:
1 % of nominal system voltage
Range:
A04 Mains Undervoltage – 150%
Default value:
110 %
Delay:
0,1 s
Threshold for detection of mains failure due to overvoltage. The setpoint is adjusted relative to the
nominal system voltage (setpoint B01 Nominal Voltage Ph-N or B02 Nominal Voltage Ph-Ph
depending on B04 Connection Type setting).
A04
Mains Undervoltage
Units:
percentage [%]
Step:
1 % of nominal system voltage
Range:
50 – A03 Mains Overvoltage
Default value:
60 %
Delay:
0,1 s
Threshold for detection of mains failure due to overvoltage. The setpoint is adjusted relative to the
nominal system voltage (setpoint B01 Nominal Voltage Ph-N or B02 Nominal Voltage Ph-Ph
depending on B04 Connection Type setting).
