DPG-2201-00X Digital Controllers
Woodward
20
The controller detects an over speed condition when it measures an engine speed
that exceeds the OVER SPEED LIMIT value. When an over speed is detected the
controller’s actuator output signal is set to minimum.
NOTE for DPG-2201-002 Models:
When the No. of Flywheel Teeth parameter is used, the OVER SPEED LIMIT
parameter is displayed in RPM values instead of Hertz values.
NOTE— The controller must be turned off to clear the over speed
detection before the engine can be restarted.
3.26 Set Speed A Min (optional)
Set Speed A Min is used to set the lowest value allowed for adjustments of Set
Speed A. This parameter can be set to any value within the range bordered by 10
Hertz (or its RPM equivalent) and the current value of Set Speed A.
3.27 Set Speed A Max (optional)
Set Speed A Max is used to set the highest value allowed for adjustments of Set
Speed A. This parameter can be set to any value within the range bordered by
current Set Speed A setting and 11,000 Hertz (or its RPM equivalent).
3.28 Set Speed B Min (optional)
Set Speed B Min is used to set the lowest value allowed for adjustments of Set
Speed B. This parameter can be set to any value within the range bordered by 10
Hertz (or its RPM equivalent) and the current value of Set Speed B.
3.29 Set Speed B Max (optional)
Set Speed B Max is used to set the highest value allowed for adjustments of Set
Speed B. This parameter can be set to any value within the range bordered by
current Set Speed B setting and 11,000 Hertz (or its RPM equivalent).
3.30 Idle Speed Min (optional)
Idle Speed Min is used to set the lowest value allowed for adjustments of Idle
Speed. This parameter can be set to any value within the range of 10 Hertz (or its
RPM equivalent) and the current value of Idle Speed.
3.31 Idle Speed Max (optional)
Idle Speed Max is used to set the highest value allowed for adjustments of Idle
Speed. This parameter can be set to any value within the range bordered by
current Idle Speed and 11,000 Hertz (or its RPM equivalent).
3.32 Duty Cycle Limit (optional)
The duty cycle limit parameter sets the absolute maximum amount of drive signal
that can be output to the actuator and thus serves as a mechanism for fuel
limiting. Fuel limiting is achieved by setting the maximum duty cycle or ontime
