Operation 4-17
MN2417
Table 4-9 Setpoints Continued
Start RPM
“Firing” speed when iL controller stops cranking (starter goes OFF).
Step: 1% of nominal RPM; Range: 5 − 50 %
Starting POil When reached controller stops cranking (starter goes OFF).
Step: 0,1 psi; Range: −100 − 10000
Note: There are three conditions for stop cranking: Starting RPM,
StartingPOil and D+ (when enabled). Starter goes off when any
of these conditions is valid.
Prestart time Time of closing of the PRE−START output prior to the engine start.
Set to zero if you want to leave the output PRE−START open.
Step: 1s; Range: 0 − 600 s
MaxCrank time Maximum time limit of cranking. Step: 1s; Range: 1 − 60 s
CrnkFail pause Pause between crank attempts. Step: 1s; Range: 5 − 60 s
Crank attemps Max number of crank attempts. Step: 1; Range: 1 − 10
Idle time Idle time delay starts when RPM exceeds Start RPM . Start fail is detected
when during Idle state RPM decreases below 2.
During the Idle time timer running the binary output IDLE/NOMINAL is
opened, when it elapses the IDLE/NOMINAL output closes.
Binary output IDLE/NOMINAL opens during Cooling period again.
Step: 1 s; Range: 0 − 600 s
Note: If the IDLE function not supported on the governor, set the Idle time
nevertheless to minimum 5s to avoid Underspeed possibly
caused by instability of the engine short after start.
