Strt Lmt P2 (%/LSS)
Start limit P2 [%/LSS] is the level at which the startfuel limit will ramp to after start from
Start fuel Limit P1 setpoint.
Strt Lmt Rate (units/s)
Start Limit Rate is the ramp rate at which the start fuel limit will ramp from Start Fuel limit
P2 to Start Fuel limit P1.
Clutch Fuel Limit
When the engine is started in the propulsion mode, the Clutch Fuel Limit is activated after
the Start fuel limit has been disabled. This limit will set the maximum fuel rack until the
engine is clutched.
Max Fuel Limit
As soon as the clutch feedback has been received, the clutch fuel limit will be disabled
and the maximum fuel limit will be activated. This maximum fuel Limit will set the
maximum possible fuel rack position during normal operation.
Load Limit (%Act)
The Load Limit parameter is the maximum fuel rack position when the Load Limit contact
is activated. If required, the control ramps down to this Load Limit position with the Load
Limit Rate.
Load Limit Rate (%Act/sec)
The Load Limit Rate is the rate at which the actuator output will ramp to the Load Limit
setpoint in case the actual actuator position is higher than the Load Limit setpoint.
Boost Lim in A (mA)
Manifold air pressure input signal (mA) point A. This field sets the first input signal for the
manifold air pressure fuel limit value.
Boost Lim val A (%)
Manifold air pressure Limit value A (% Act). This field sets the maximum possible
actuator output when the Manifold Air pressure input has reached the value as set in the
Boost Lim in A (mA) setpoint.
Boost Lim in B (mA)
Manifold air pressure input signal (mA) point B. This field sets the second input signal for
the manifold air pressure fuel limit value.
Boost Lim val B (%)
Manifold air pressure Limit value B (% Act). This field sets the maximum possible
actuator output when the Manifold Air pressure input has reached the value as set in the
Boost Lim in B (mA) setpoint.
Boost Lim in C (mA)
Manifold air pressure input signal (mA) point C. This field sets the third input signal for the
manifold air pressure fuel limit value.
Boost Lim valC (%)
Manifold air pressure Limit value C (% Act). This field sets the maximum possible
actuator output when the Manifold Air pressure input has reached the value as set in the
Boost Lim in C (mA) setpoint.
Boost Lim in D (mA)
Manifold air pressure input signal (mA) point D. This field sets the fourth input signal for
the manifold air pressure fuel limit value.
