Operation
Turning the control system key to the run position
energizes the ECU and a start-up screen is displayed
while a self test is performed. If the display beeps for
longer than 1 second, it indicates a self test fault.
Users can attempt to rectify the fault by restoring
factory defaults (see
Configuration Menu
for details).
Contact Yanmar for assistance if the fault persists.
After the start-up screen is cleared, the display shows
readings on its virtual gauges. Initially the analog
gauges are displayed but the display uses the last
displayed screen on subsequent startups (see
Preferred Screen Store for details).
If the ECU is preheating when the key switch is
turned to the run position, the preheat splash screen is displays. Preheat time varies with atmospheric and
engine conditions. After preheat finishes the display changes to indicate the engine can be cranked. The
engine is cranked by turning and holding the key switch in the start position until the engine starts.
Note
The ECU will not preheat unless conditions warrant. If necessary, starting the engine may be
attempted by turning the key to the start position without waiting for preheat to expire.
The key switch is spring loaded to return automatically to the run position when released.
The key switch includes an interlock to prevent the key from being turned to the start position
while the engine is running. The key switch must be turned to the off position to reset the
starter interlock before the switch can be turned to the start position again.
Throttle Control
The type of throttle operators installed along with the configured values of Minimum Requested RPM, Idle
RPM, Intermediate RPM, Run RPM and Maximum Requested RPM determine throttle operation. The engine
speed can be adjusted above Run RPM and below Idle RPM but the requests can not fall below Minimum
Requested RPM or above Maximum Requested RPM. The ECU determines how the engine responds to the
throttle requests and will not allow the engine speed to fall below the ECU minimum or maximum RPM.
Note
The
Minimum Requested RPM
and
Maximum Requested RPM
can only be configured using the CANplus Configuration software.
See
Configuration
below for more information.
Ramp Throttle
The standard Ramp Throttle uses a momentary rocker switch to adjust the requested engine speed. When
first started the requested engine speed is
Idle RPM
. Pressing and releasing the rabbit icon increases the
speed requested by 25 RPM. Pressing and holding the rabbit icon causes the speed to accelerate to full
speed in a few seconds. Similarly, pressing the turtle icon
decreases the requested speed.
