i06042410

Number of configuration parameters

System configuration parameters affect emissions and engine power. These ones

The default values of the parameters are programmed at the factory. Some parameters are available

Changes are made by the customer to suit the needs of the particular application.

Parameter Description

"Device ID"

"EquipmentID" (equipment identification number)

Enter a segment in the sub control module (ECM) to identify the

Instructions. You can enter up to 17 characters in the field. This parameter

For customer reference only. This parameter is not required.

Figure 15

g00763900

"Engine Serial Number"

"TEL" is a customer programmable parameter that defines the maximum power

The maximum engine speed allowed at the rate. Up to "TEL"

It is programmed at the maximum engine rated speed. "TEL" passed

Definition of engine overload running curve.

Perform "EngineSerialNumber"

Programming to match the engine sequence embossed on the engine nameplate

The column numbers match. If the ECM is replaced, the engine information must be

The engine serial number on the nameplate is programmed into the new ECM.

"Engine acceleration"

Note: When you apply for a factory password, be sure to use the programming settings in ECM

Engine serial number in.

"EngineAccelerationRate"

Determines the rate of change of engine speed (acceleration) during PTO operation

Or slow down). This rate of change can also be used to achieve intermediate engines

Rotating speed.

"Rated Number"

"RatingNumber" corresponds to the application

A selected set of performance maps. This selected group of performance engineers

Condition diagrams are taken from specific sets of conditions stored in flash files

Illustration. If there are multiple ratings, agents and / or OEMs need

Select the applicable rating. Ratings range from "A" to "E".

"Low idling speed"

"LowIdleSpeed" is the engine's most

Low allowable working speed. This parameter can be programmed from 600 to

1400rpm.

Note: The modification of “RatingNumber” requires the use of labor

Factory password.

"Power Output (PTO) Mode"

"PTOMode" allows the ECM to be programmed to

One of two optional PTO configurations.

“Climb Climb / Descent Descent” – when “PTOMode” is programmed

Set to "RampUp / RampDown"

At the same time, the ECM allows the PTO to operate using traditional functions.

“Set / Reset” – when “PTOMode” is programmed

When set to "Set / Resume", ECM allows

Allows PTO to operate with enhanced functions.

"High idle speed"

"HighIdleSpeed" means the throttle or

Maximum no-load engine speed when the PTO switch is in the maximum position.

Rotating speed. This parameter can be set to “LowIdleSpeed”

(Low idle speed) to any engine speed between "TEL"

speed. Engine speed will start with "EngineAcceleration

Rate ”(engine acceleration rate) programmed acceleration

The rate increases or decreases.

Note: If the engine speed is too high and "AirShutoff"

(Air Shutdown) is programmed to “Enabled”,

Must first cycle the ECM's switching power supply and manually reset the air to shut off the electromagnetic

Valve before the engine can restart.
