Phase sequence check is not possible to evaluate under voltage 50V what causes that if measured
voltage 50V is within the allowed range, controller will not allow to close the GCB, even if relevant LED
diode on front panel of IL-NT lits.
NomVolts Ph-Ph
[V]
Nominal generator voltage (phase to phase)
Step:
1V
Range:
138
– 35000 V
Nominal Freq
[Hz]
Nominal generator frequency (usually 50 or 60 Hz )
Step:
1Hz
Range:
45
– 65 Hz
Gear Teeth
[-]
Number of teeth on the engine gear for the pick-up.
Set to zero, if no pick-up is used. Engine speed is counted from the generator frequency.
Step:
1
Range:
0
– 500
Hint:
Generator frequency can be used only when generator voltage (min 10Vef) is present before reaching
of the firing speed (
Starting RPM
) after start.
Nominal RPM
[RPM]
Nominal engine speed.
Step:
1RPM
Range:
100
– 4000 RPM
ControllerMode
[ OFF, MAN, AUT,*TEST ]
Equivalent to Controller mode changes by MODE
or
MODE buttons.
Hint:
Controller Mode change can be separately password protected.
Reset To MAN
[ENABLED/DISABLED]
DISABLED:
Controller stays in AUT Mode after Fault Reset .
ENABLED:
Automatic switch from AUT (or TEST) to MAN Mode after Fault Reset to avoid
automatic engine start. This function is active for Shut down protection only.
ConnectionType
[3Ph4Wire / 3Ph3Wire / Split Ph / Mono Ph]
Generator winding connection.
3Ph4Wire:
STAR Connection, 3 phases and neutral - 4 wires,
Three phase “wye” measurement – 3PY, 3x CT‘s
3Ph3Wire:
DELTA Connection, 3 Phase without neutral - 3 Wires,
Three phase “delta” measurement – 3PD, 3x CT‘s
Split Phase:
DOUBLE DELTA Connection, Split Phase,
Single-phase measurement
– 1PH, 1xCT
Mono Phase: MONOPHASE,
Single-phase measurement
– 1PH, 1x CT
Hint:
For more details about connection types see
Voltage measurement and generator connection types
chapter.
