NOTE: WAIT FOR ECU is displayed if ECU is selected in engine type.
This is a fixed 10 second delay to allow the ECU to warm up prior to cranking.
• When the “WAIT FOR ECU” delay expires, the following will occur:
The STATE: text line will display “CRANK ON/OFF”.
NOTE: A NO SPEED SIGNAL shutdown will occur (when enabled) if the
controller does not read a frequency within 3 seconds after cranking begins.
The Alt excite output is turned ON.
The crank output is turned ON and cycle cranking begins at this point for all engine types.
NOTE: CYCLE CRANKING. If the engine does not start on the first crank, the
controller will de-energize the starter output for the rest cycle.
NOTE: OVERCRANK. If the engine fails to start after the number of cranking
attempts is exceeded, OVERCRANK will be indicated on the display. The auto
start sequence will be stopped, requiring manual reset of the controller. The
controller is reset by moving the panel key switch to the "OFF" position.
• When the engine speed rises above the crank stop set point, the following will occur:
The STATE: text line will display “WARMUP”.
The “warm-up delay” begins timing.
The crank output is turned OFF.
The prestart output is turned OFF.
The internal hourmeter begins recording engine run hours.
The engine is throttled to the “WARMUP RPM” set point.
NOTE: If “mechanical” is selected as the engine type, the AT03069 throttle
actuator will throttle the engine. If “electronic” is selected, the ECU throttling is
determined by what is selected in the in the “ECU THROTTLE TYPE”.
The “shutdown lockout” delay begins timing. When this delay expires, the following
shutdown/alarms are armed:
- LOW OIL PRESSURE.
- HIGH ENGINE TEMPERATURE.
- LOSS OF SPEED.
- ALT FAIL/LOW BAT. Self-clearing alarm.
NOTE: If the engine speed drops below the “crank stop” set point before the
“shutdown lockout” delay expires, the “re-crank” delay begins timing. When this
delay expires, cycle cranking will resume.
