4.4.4.1 Front Panel Speed Control
The operator is able to adjust the speed of the engine by using the controller's front panel. This section describes the two
methods available for implementing speed control, the settings and parameters to be used, as well as the necessary
instructions allowing the operator to control the speed.
Speed Control Methods
Setting Description
Front Panel Speed Control using J1939
TSC1 The controller can instruct the ECM of an electronic engine to adjust its speed by
broadcasting the TSC1 command.
Refer to the J1939 Manual for more information.
Front Panel Speed Control using Switched
Outputs The controller can instruct the ECM of an electronic engine to adjust its speed by
using switched outputs on the controller set to RPM Increment and RPM
Decrement to interface with digital inputs on the ECM. When the speed is
changed, the corresponding switched output will be on for 1 second each time
increment or decrement is pressed.
See the rest of this section for more information.
Aux 4 Speed Control The Auxiliary sensor 4 is used to determine the setpoint speed. The speed is
adjusted with the TSC1 J1939 command.
Refer to the J1939 Manual for more information.
WARNING : Switched outputs have a floating voltage of approximately 8V when off. If using the outputs for digital
logic, it will be necessary to put a pull-down resistor (1kOhm, 1 Watt) from the output to ground to ensure a low
logic level when output is off.

The minimum or maximum RPM that the engine speed can be
adjusted around the Rated RPM. Example: Rated RPM is
1800 and Speed Bias is 150. The minimum RPM will be 1650
and maximum RPM will be 1950. Only valid when the correct
limit method is chosen.
