- Warning
- Shutdown
Different setpoints are based on the engine application and the engine rating. The default settings that are programmed at the factory are listed in Table 1.
| Overspeed | |
| Parameter | Default Setting |
| Warning setpoint | 1.18 times the rated rpm |
| Warning delay | 0 seconds |
| Shutdown setpoint | 1.18 times the rated rpm |
| Shutdown delay | 0 seconds |
| Hysteresis | 100 rpm |
| Security level | Required password |
If the engine speed exceeds the setpoint rpm, a warning and a shutdown will occur. The fuel will be shut off and the air shutoff (if equipped) will be activated.
The air shutoff must be reset before the engine can be restarted. Ensure that both of the air shutoffs are reset.
Note: The default settings for the warning and for the shutdown are equal. Therefore, the warning and the shutdown occur simultaneously. These settings were selected in order to log both a warning and a shutdown: furthermore, an overspeed condition can occur rapidly.
The setpoints can be programmed to a value between 1200 and 2400 rpm.
