DPG-2223-00X Controllers
Manual 36522G
For example: If the highest set speed is 1800 RPM and this parameter is set to
20, then an over speed condition will be detected at 2160 RPM (the value that is
20% greater than 1800). Formula: 1.20 * 1800 RPM = 2160 RPM
The default value of 100 is used to disable over speed detection. Use values less
than 100 to enable the over speed limit function and set the limit speed to [(1 +
(overspeed_limit_value/100)) * (highest_set_speed)].
DPG-2223-002 Models:
This parameter is used to determine the engine speed that will trigger the
controller to output minimum fuel. The parameter’s value is set as a frequency in
Hertz or as a RPM value depending on whether the Number of Flywheel Teeth
parameter is zero or nonzero respectively. The default value of 15,000 Hertz is
used to disable over speed detection.
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.
The controller must be turned off to clear the over
speed detection before the engine can be restarted.
3.28 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.
3.29 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).
3.30 Idle Speed Min (optional)
This parameter sets the minimum value that the Idle Speed parameter is allowed
to have. This parameter can be set to any value within the range bordered by 10
Hertz (or its RPM equivalent) and the current value of Idle Speed.
3.31 Idle Speed Max (optional)
This parameter sets the maximum value that the Idle Speed parameter is allowed
to have. This parameter can be set to any value within the range bordered by
current Idle Speed setting and 11,000 Hertz (or its RPM equivalent).
When the No. of Flywheel Teeth parameter is used, the
REMOTE SPEED MIN, REMOTE SPEED MAX, SET
SPEED A, IDLE SPEED, OVER SPEED LIMIT, SET
SPEED A MIN, SET SPEED A MAX, IDLE SPEED MIN,
IDLE SPEED MAX and STARTUP SPEED parameters are
displayed as RPM values instead of Hertz values.
