CONTROL FUNCTIONS (CONT’D)
Utilizing features 1 and 2 above permits establishing a remote (auto) start/stop system that can be operated through an external sequence. See [Figure 10-40-30] for details. In the figure, a machine start recognition signal (E8) is given from an external control device in place of the key switch.
Run
• Goes off when the engine stops.
Start signal
• Must be tuned off when it is detected that the engine has started.
• Must be turned off within 160 seconds if it is not detected that the engine has started.
The engine run signal goes on at engine start and goes off at engine stop. The start signal must be turned off within 160 seconds as a guideline. Otherwise, the starter tries to start the engine repeatedly in intervals of 30 seconds when the engine may not be able to start for some reason.

Application Interface Outline (Cont’d)
Speed selection
The Eco-governor has a speed selection feature that allows the engine speed to be changed with external switch inputs. The speed selection feature includes three modes: (1) Constant speed mode where the engine speed is kept constant, (2) Constant deceleration mode where the engine speed is reduced from a specified value with a constant deceleration, and (3) Auto deceleration mode where the engine speed is set to a specified value after a specified time has elapsed.
The table below shows the relationship between the position of external switches and the engine speed in the three modes.
External
(1) Constant speed
(2) Constant deceleration or 3
(3) Auto deceleration
Values marked with an asterisk (*1-*4) can be changed by map setting (optional). Values marked with an asterisk (*2) is used in map as well. External switch’s ON/OFF can be commanded via CAN communication.
