There are seven possible ways to define whether the engine is running or not:
•
Directly from the electronic control unit (ECU) of the engine (if connected via CAN0
CAN-BUS, P.0700 <> 0).
•
Engine speed (RPM) The engine is in motion if the rotation speed is above P.0225
threshold ("Started engine threshold (rpm)"; it is considered stopped if the rotation
speed is below P.0224 threshold ("Stopped engine threshold (rpm)"). This control is
not used if:
o
The rotation speed is not available (see above).
o
P.0224=0.
o
P.0225=0.
o
P.0224 > P.0225.
•
From the voltage of the signal D + of the engine battery charger alternator. The engine
is in motion if the tension +D is above P.0230 threshold ("Started engine threshold
(+D)"; it is considered stopped if the rotation speed is below P.0231 threshold
("Stopped engine threshold (+D)"). This control is not used if:
o
The measurement of vD is not available (P.4041 set with a different
function from DIF.1300 "D").
o
P.0230=0.
o
P.0231=0.
o
P.0230 > P.0231.
•
From low and/or minimum lubricant pressure contacts or from the thresholds on the
oil pressure analogue measure. The engine is in motion if at least one of the contacts
is open (if there is pressure)
or if the oil pressure measurement is higher than the low
or minimum thresholds; it is considered stopped if all the contacts are closed (no
pressure) and the oil pressure measure is not available or if it is lower than the low
and minimum thresholds. This control is not used if:
o
No digital input acquires low and/or minimum lubricant pressure contacts (no
input configured with DIF.4221 and DIF.4222 functions) and the oil pressure
measure is not available or the low (P.0339) and minimum (P.0341)
thresholds are both “0”.
o
If P.0232 parameter ("Engine started from oil pressure contacts") is set to
zero.
•
From generator AC voltage. The engine is in motion if the tension is above P.0227
threshold ("Started engine threshold (Vac)"; it is considered stopped if the tension is
below P.0226 threshold ("Stopped engine threshold (Vac)"). This control is not used
if:
o
P.0226=0.
o
P.0227=0.
o
P.0226 > P.0227.
•
From generator AC frequency. The engine is in motion if the frequency is above
P.0229 threshold ("Started engine threshold (Hz)"; it is considered stopped if the
frequency is below P.0228 threshold ("Stopped engine threshold (Hz)"). This control
is not used if:
o
P.0228=0.
