6. Autostart Operation
6.4.6 Configuring RPM and Time Profile Settings
Idle RPM
Selects the RPM the control system will request for idle speed. If
the engine is started, it will always begin running at Idle speed.
Intermediate RPM
Selects the RPM the control system will request for intermediate
speed. Intermediate speed is a specific speed point that the en-
gine will pause at during the ramping up cycle. The intermediate
speed can be used to prime a pump or charge lines.
Run RPM
Selects the RPM the control system will request for run speed.
The run speed is the normal operating speed. If the Maintain
Transducer Level ”cruise control” is enabled, the control panel
will dynamically throttle the engine to maintain the level using the
Run RPM as the max.
Warm Up Time
The time in seconds the engine will stay at the Idle RPM after
starting.
Ramp to Intermediate Time
The time in seconds the engine will take to ramp from the Idle
RPM to the Intermediate RPM.
Intermediate Time
The time in seconds the engine will stay at the Intermediate RPM.
Ramp to Run Time
The time in seconds the engine will take to ramp from the Inter-
mediate RPM to the Run RPM. If the Maintain Transducer Level
is enabled, the panel will not ramp to the Run RPM but will start
dynamically throttling the engine to maintain the level.
Ramp to Cooldown Time
The time in seconds the engine will take to ramp from the Run
RPM to the Cooldown RPM.
Cooldown Time
The time in
minutes
the engine will stay at the Cooldown RPM
before turning off the engine.
Instead of time-based, the ramp profile can an event to occur before Ramping to Run. The events
can be:
• Pump is primed
• Clutch/gearbox is enabled
6.5 Transducers
The transducers can be configured for Autostart levels, scaled values, units of measure for setup
and display, calibration, warning and fault levels.
6.5.1 Autostart Triggers
The low and high Autostart trigger levels can be set via
Autostart Transducer Autostart Triggers
