BusNomV
[ V – kV* ] (FV)
Nominal bus voltage (phase to neutral).
Step:
1 V / 0,01 kV*
Range:
80 V – 346,41 kV*
Force value possibility: Yes
*Note:
The actual setpoint units and range depend on setting of the Power format (see GenConfig manual).
Hint:
The nominal value can be externally changed using Force value function. However, it is intended for
changes between standard nominal voltages only (230 / 120 V) using
ForceValueInXX
source setpoints.
It is prohibited to use another controller values as a source for Force value in this case!!!
Both Gen and Mains nominal voltages must be set to the same value when no VT is used.
BusNomVph-ph
[ V – kV* ]
Nominal bus voltage (phase to phase).
Step:
1 V / 0,01 kV*
Range:
130 V – 600,00 kV
*Note:
The actual setpoint units and range depend on setting of the Power format (see GenConfig manual).
Hint:
Both Gen and Bus nominal voltages must be set to the same value when no VT is used.
FixVoltProtSel
[ PHASE-NEUTRAL / PHASE-PHASE ]
PHASE-NEUTRAL:The generator and mains/bus voltage protections are based on phase-to-neutral voltages.
PHASE-PHASE:
The generator and mains/bus voltage protections are based on phase-to-phase voltages.
Nominal freq
[ Hz ] (FV)
Nominal generator frequency (usually 50 or 60 Hz).
Step:
1Hz
Range:
45 – 65 Hz
Force value possibility: Yes
Hint:
The nominal value can be externally changed using Force value function. However, it is intended for
changes between standard nominal frequencies only (50 / 60 Hz) using
ForceValueInXX
source setpoints.
It is prohibited to use another controller values as a source for Force value in this case!!!
Gear teeth
[ ]
Number of teeth on the engine’s flywheel for the pick-up sensor.
Set to Fgen->RPM, if no pick-up sensor is used. In that case, engine speed is calculated from the generator
frequency.
Step:
1
Range:
Fgen->RPM, 1 – 500
Hint:
Generator frequency can be used (for RPM measuring) only when generator voltage (min 10V) is present
during cranking. This is in general not suitable option for gas engines!
Gear teeth should not be set to zero when
Engine params
:
Fuel solenoid
= GAS ENGINE (it is likely that
RPM would not reach 30, the gen-set wouldn’t start and gas valve would not open – see
Fuel solenoid
).
Some electronic engines provide their own cranking and preheat cycle (e.g. CAT EMCP3). In such case, set
Gear teeth = 0, otherwise it may not be possible to start the engine.
Nominal RPM
[ RPM ]
(FV)
Nominal speed of the engine.
Step:
1RPM
Range:
100 – 4000 RPM
Force value possibility: Yes
The following table shows the relationship between frequency and nominal RPM due to generator poles:
