723PLUS Digital Marine Control Manual 26482
04 IDLE REF @ SHUTDOWN (*T/F)—If set to "TRUE", every time the engine is
shut down (engine speed falls below 5% of rated speed) the speed reference will
reset to the Idle set point (if remote speed setting is selected, the speed
reference is reset to idle and, after one second, it will ramp to the remote speed
setting). If set to "FALSE", the speed reference will stay at its present value when
the engine is shut down.
05 IDLE WHEN LON FAIL (*T/F)—If set to "TRUE", a Control LON
communications failure between the two 723PLUS controls will cause the speed
reference to reset to idle. Engine speed will remain at idle until communication is
restored. If set to "FALSE", the speed references will lock in last.
06 MAN MODE SPD STPT (*100–2200)—Set this value for the engine speed
when the maneuvering mode discrete input is closed.
B**CONFIG OPTION**
01 LON ADDRESS CH#1 is the node address for LON Channel #1 and must be
set at 1 or 2. The node address must be the same for both LON Channels #1 and
#2 within the same 723PLUS control. The mating 723PLUS control must be
assigned the remaining node address choice.
02 LON ADDRESS CH#2 is the node address for LON Channel #2 and must be
set at 1 or 2. The node address must be the same for both LON Channels #1 and
#2 within the same 723PLUS control. The mating 723PLUS control must be
assigned the remaining node address choice.
03 OVERRIDE FAILSAFE (*T/F)—Set this value "FALSE" to have the actuator
output go to the MINIMUM fuel position on loss of engine speed input signal/
signals. Set this value "TRUE" to have the actuator output go to the MAXIMUM
fuel position on loss of engine speed input signal(s). This function will activate
only when Reverse Acting Act is also "TRUE".
04 REVERSE ACTING ACT (*T/F)—Set this value "FALSE" for forward (direct)
acting actuators and "TRUE" for reverse (indirect) acting actuators.
05 MANUAL CLUTCH LOGIC (*T/F)—Set this value "TRUE" to enable manual
clutch logic. When manual clutch logic is selected, engine synchronizing must be
done manually and a clutch permissive output will not be issued by the
723PLUS. Torque sharing is initiated when a clutch engaged contact is sensed.
Soft loading operates as normal, however soft unloading is not possible due to
the absence of the clutch request function.
06 CONT A OPEN TO RUN (T/F)—Set this value "FALSE" for "Open to Run",
normal speed control function is enabled when this input is open. If this value is
closed (discrete input in the "TRUE" state), the Minimum Fuel Function will
immediately pull the fuel demand to zero. The control output to the actuator will
be the minimum fuel demand when voltage is applied to terminal 29.
07 MAJOR ALM SD ACT (*T/F)—Set this value "TRUE" to have the control
return to minimum fuel if a major alarm is detected. USE NOTCH FILTER
(*T/F)—Set this value TRUE to enable the notch filter. The notch filter is useful
for dampening otherwise uncontrollable system harmonics. It can be used as a
flexible coupling torsional frequency filter if two speed sensors are not available.
