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:
Generator poles 50 Hz 60 Hz
2 3000 3600
4 1500 1800
6 1000 1200
Hint:
Generator frequency can be used (for RPM measuring) only when generator voltage (min 10V) is present
during cranking.
When pick-up cut (fail) comes, InteliSys detects under speed and stops the engine.
ControllerMode [ OFF / MAN / SEM / AUT ] (FV)
Equivalent to Controller mode changes by MODE→ or ←MODE buttons.
Force value possibility: Yes
Hint:
Mode change can be separately password protected.
FltRes GoToMAN [ DISABLED / ENABLED ] (FV)
DISABLED: Controller stays in AUT mode after Fault reset .
ENABLED: Automatic switch from SEM / AUT to MAN mode after Fault reset to avoid automatic engine
start. This function is active for all 2
nd
-level protections (Shut down, Slow stop, ElProt, Off-load).
Force value possibility: Yes
Hint:
It is not possible to reset a Fault when Binary input Remote AUT is closed or another mode forcing function
is active.
Set to ENABLED to avoid automatic engine start when Fault reset button is pressed after shut down in
automatic mode.
Local buttons [ PANEL / EXTBUTTONS / BOTH ]
PANEL: Only the buttons on the controller front panel are enabled.
EXTBUTTONS: Only the external signals (copies of the panel buttons) are enabled.
BOTH: Both controller buttons and external signals are enabled.
Hint:
This switch is valid for these signals: GCBButton, FaultResButton, HornResButton, StartButton, StopButton.
