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
.

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
.
