Table 8.9 Crank parameters
Parameter Range Default Comment
Crank on 1 s to 3 min 5 s
For the Crank on part of the start sequence, the controller activates the Crank
output for this period.
Crank off 1 s to 3 min 5 s
If there is no running detection during Crank on, then the controller deactivates the
Crank output for this period.
Disengage
crank
1 to 2000 RPM 400 RPM
The controller deactivates the Crank output when the engine speed reaches this set
point, although the Crank on timer continues to run. This parameter only has an
effect if an engine speed measurement (for example, an MPU/W/NPN/PNP) is
configured.
Even when Disengage crank is used, the start sequence tries to detect that the
engine is running for the whole of the Crank on time.
Configure these parameters under Configure > Parameters > Engine > Start sequence > Start attempts.
Parameter
Range Default Comment
Normal 1 to 10 3
This parameter limits the wear on the genset from too many start attempts. This is the maximum
number of start attempts.
If the genset does not start after these attempts, the Start failure alarm is activated.
Configure this parameter under Configure > Parameters > Engine > Running detection > Engine ready.
Parameter
Range Default Comment
Delay 1 s to 5 min 2 s
After Running detection is ON, the engine must run for this period before the breaker close
sequence can start.
Parameters (optional)
Optional. You must configure the Engine > Start prepare digital output to see these parameters. Configure these parameters under
Configure > Parameters > Engine > Start sequence > Start prepare.
Table 8.10
Start prepare parameters
Parameter Range Default Comment
Start prepare 0 s to 5 min 5 s
Optional. If the start conditions are OK, the controller activates the Start prepare
output for this time. When the Start prepare timer expires, the controller activates the
Crank output. See Start prepare in the Engine start sequence.
Extended start
prepare
0 to 20 s 0 s
Optional. The controller keeps the Start prepare output activated for this time during
cranking.
Optional. You must configure the Engine > Run coil digital output to see these parameters. Configure these parameters under
Configure > Parameters > Engine > Start sequence > Run coil.
