Announcement of failure (and other protection) of the ECU value of the binin type is blocked if a
communication error with ECU is declared in AL
activated in the same way as LBO ECU Comm Lost
activated after timeout based on ESF (quickest RX frame + 100ms, at least 300ms)
activated 3s after controller start if ECU does not communicate
deactivated immediately after ECU starts to communicate
ECU alarm can be blocked by LBI or by ECU Power relay mechanism
LBO ECU Comm. Fail mirroring alarm activity but it is activated even if protection blocked (see above)
and even if protection level of module is set to no protection
deactivated 3s after deactivation of LBO ECU Comm Lost
LBI ECU Comm Fail Block or deactivated ECU power relay (if used) also blocks FLS protection on ECU
inputs
Requested RPM, Overload protection (AS only)
Idle Offset [RPM] = Idle RPM [RPM] + (Idle Offset [%] / 100) x (Nominal RPM [RPM] – Idle RPM [RPM])
Engine Values: Speed Request is value in the range 0,0 to 100,0%.
Engine Values: Speed Request can be changed
From analog input configured as Logical Analog Input Requested RPM.
Via binary inputs Speed Up, Speed Down with ramp BI Speed Ramp.
From ID panel using Fast edit function.
See Engine Values: Speed Request charts for Engine Values (page 256) and Engine Values (page
256) modes.
When Logical Analog Input Requested RPM indicates sensor fail or it is not configured and Binary input
Back Up Speed is closed the Loadsharing: ThrottlePos value is adjusted to the Loadsharing: Back Up
Speed, the ThrottlePos value change is influenced by ramp Loadsharing: RQSP Ramp.
