NOTE: If the user does not manually throttle down the engine, it will not idle
down in COOLDOWN before the engine is shut down.
The clutch output is turned OFF when the engine speed drops to the “clutch disengage”
RPM set point.
The “low discharge pressure” shutdown is ignored.
When the “cooldown delay” expires, the following will occur:
The SELECTOR: text line will display “AUTO” and the STATE: text line will display “PANEL
READY”.
The fuel/ECU enable is turned OFF.
The Alt excite output is turned OFF.
The internal hourmeter stops recording engine run hours.
All shutdowns are ignored.
Controller will “Go to Sleep” after 30 minutes of inactivity once engine has shutdown to
conserve battery life. The controller will awake once any key is pressed or input is enabled.
(This is Standby Mode)
The controller is now waiting and ready for another start sequence to occur.
Special Features
Shutdown History
The Controller stores the last ten (10) shutdowns that have occurred due to system malfunctions. This
record can be found in the P-numbers with the date and time stamp of the shutdown. The Shutdown
history screen will also display the last 5 shutdowns.
Float Backup
If the level transducer fails high or low, a shutdown will occur.
If the float backup feature is enabled, a shutdown will not occur and the controller will start and stop
on floats.
If the engine is already running, it will remain running until a float stop occurs. During backup float
operation, the engine is throttled to the maximum rpm set point.
NOTE: This feature remains in effect until the controller is reset, even if the transducer
comes back into range. The start/stop and throttle types will have to be set back to
TRANSDUCER to resume normal operation.
Clock Start
Regardless of the start/stop type selected, the controller will also start by selecting days and start / run
times in the P numbers. If the engine is already running from another condition, and the clock time
occurs, the clock start time is ignored.
Overspeed Shutdown
If an overspeed shutdown occurs, output 9 turns ON for 15 seconds to actuate the air damper.
