Output source
Activates… Is not active….
Inhibit Retransfer to Mains
Indicates when mains fails,Gens fails and mains not enough capacity to take load inhibit
retransfer.
Interlock Override
Comes on just before and just after the gen-set goes into parallel enabling an output for
a mechanical or electrical interlock
kW Overload Shutdown /
Electrical Trip
Active when the measured kW are above the setting of the
kW overload shutdown /
electrical trip alarm.
Can be used to give alarms on overload, control a dummy load breaker or for load
shedding functionality.
kW Overload Warning
Active when the measured kW are above the setting of the
kW overload warning alarm
Can be used to give alarms on overload, control a dummy load breaker or for load
shedding functionality.
Lamp test This output indicates that the module is performing a lamp test. Once the lamp
test is completed, the output will become inactive again. The output can be
used to feed a lamp test on external modules or panel lamps.
Loading Frequency Not Reached
Indicates that the generator frequency has not reached the configured
loading frequency
during the starting process.
Loading Voltage Not Reached
that the generator voltage has not reached the configured
loading voltage
during the starting process.
Load Shedding Control (1-5)
Becomes active when the engine kW
exceeds Load Shedding Control Trip Setting.
Inactive when the engine kW returns to
below the Load Shedding Control
Return setting.
Loss of Mag Pickup Signal
Active when the controller senses the loss of signal from the magnetic pickup probe
Louvre Control
Normally used to drive ventilation louvres for
the generator set, this output becomes active
when the fuel relay becomes active
Inactive when the fuel relay becomes
inactive.
Low Coolant Temperature
Coolant Temperature
Low Coolant Temperature alarm
setting
Low Fuel Level
IEEE 37.2 – 71 level switch
Fuel Level Low
Low Oil Pressure Shutdown
IEEE 37.2 - 63 pressure switch
Oil Pressure
the Low Oil Pressure Shutdown setting
Inactive when
• The set is stopped
• During starting sequence before the
safety delay time has expired.
Low Oil Pressure Warning
IEEE 37.2 - 63 pressure switch
Oil Pressure
the Low Oil Pressure Warning setting
Inactive when
• The set is stopped
• During starting sequence before the
safety delay time has expired.
Low Load Indicates that the stopping sequence is beginning due to low load levels.
(Load Demand Scheme)
MPU open circuit
This output indicates that the module has detected an open circuit failure in
the Magnetic Pickup transducer circuit.
Main Config Selected
Indicates that the main configuration fail has been selected
Mains Closed Aux
Mains closed auxiliary
Mains Decoupling High Frequency This output indicates that the mains decoupling high frequency alarm has
been triggered.
Mains Decoupling High Voltage This output indicates that the mains decoupling high voltage alarm has been
triggered.
Mains Decoupling Low Frequency This output indicates that the mains decoupling low frequency alarm has been
triggered.
Mains Decoupling Low Voltage This output indicates that the mains decoupling low voltage alarm has been
triggered.
Mains failed to close This output indicates the mains breaker failed to close
Mains failed to open This output indicates the mains breaker failed to open
Mains Failure
IEEE 37.2 - 81 frequency relay
IEEE 37.2 – 27AC under voltage relay
IEEE 37.2 – 59AC over voltage relay
The output indicates that one or more of the module’s sources of determining mains
failure is active.
The output is inactive when the mains supply is healthy
Mains Over Frequency
IEEE 37.2 - 81 frequency relay
Active when the mains frequency exceeds the
High Frequency
Mains Over Voltage
IEEE 37.2 – 59AC overvoltage relay
High Voltage
Mains Under Frequency
IEEE 37.2 - 81 frequency relay
Active when the mains frequency falls below the
Low Frequency
Mains Under Voltage
IEEE 37.2 – 27AC under voltage relay
Active when the mains voltage
Low Voltage
