Over- and undervoltage protection is evaluated according to Basic Settings: ConnectionType setting.
3Ph4Wire and 3Ph3Wire connections are evaluated according to Ph-Ph nominal voltage (NomVolts
Ph-Ph) and Split Phase and Mono Phase connections are evaluated according to Ph-N nominal
voltage (NomVolts Ph-N).
Gen V Del [s]
Delay for generator undervoltage and overvoltage alarm
Step: 0.1s
Range: 0.0 – 600.0 s
Volt Unbal BOC [%]
Threshold for generator voltage unbalance alarm.
Step: 1% of Nominal voltage
Range: 0 – 200% of Nominal voltage
Volt Unbal Del [s]
Delay for generator voltage unbalance alarm.
Step: 0.1s
Range: 0.0 – 600.0 s
Gen >Freq BOC [%]
Threshold for generator phase L1 overfrequency.
Step: 0.1% of Nominal frequency
Range: 0 (Gen <Freq BOC) – 200.0% of Nominal frequency
Gen <Freq BOC [%]
Threshold for generator phase L1 underfrequency.
Step: 0.1% of Nominal frequency
Range: 0.0 – 200 (Gen >Freq BOC) % of Nominal frequency
Gen Freq Del [s]
Delay for generator underfrequency and overfrequency alarm.
Step: 0.1s
Range: 0.0 – 600.0 s
AMF Settings
Operation Mode [AMF/MRS/SLAVE/MASTER]
Based on this setpoint is defined basic controller function.
AMF: Normal AMF operation
MRS: When MRS mode is selected the controller will not perform AMF functions anymore. MCB
button will be inactive and also mains measurement and protections will be disabled. The
controller will keep TEST mode and the genset in AUT mode will be able to start by Rem
Start/Stop binary input.
Hint:
When the AMF controller operates in MRS mode and detects voltage on Mains terminals Wrn MainsV
Det. is displayed in Alarm list.
SLAVE/MASTER:
When SLAVE or MASTER is selected the controller will perform Dual Mutual Standby function.
Hint:
MASTER or SLAVE can be also defined by binary input DualAMFRole with higher priority than
Operation Mode setpoint.
