Module Communication Error:
communication is lost between the LDU
and MCU modules.
•
Some of the errors listed above can be
acknowledged and silenced. This is allowed
when the motion control levers are in the neutral
lock position and the LDU middle push button is
pressed down and held.
Acknowledging an error will remove the error
message from the engine temperature, engine
rpm, or fuel level icon area and silence the audible
alarm. However, the error will continue to display
on the active error screen in the Maintenance and
Service Menu and the status LED will continue to
be illuminated red.
– The following errors will emit a slow chirping
sound and can be acknowledged and silenced:
◊
Service Engine Oil
◊
Service Transmission Oil
◊
Fuel Low
◊
Clutch Overcurrent
◊
Clutch Reset Required
◊
Engine Error Codes
– The following errors emit a fast chirping sound
and can be acknowledged and silenced:
◊
System Overvoltage>16VDC
◊
System Undervoltage<9VDC
– The following error codes emit a fast chirping
sound and cannot be acknowledged or
silenced.

Low Oil Pressure
◊

Clutch Output Failure
•
In order to protect the system components from
exceeding threshold limits, the RED technology
system is designed to limit the engine speed
and/or disengage the clutch which allows the
machine to be driven onto a trailer or returned to a
service area.
There are five errors:
1.
Clutch Overcurrent
If an overcurrent event occurs, the system
will limit the engine speed to the default
Efficient Transport Mode speed and place
the machine in “Safe Transport Mode”. Safe
Transport Mode limits the engine speed,
locks out the PTO, and disengages the
clutch; a “Clutch Overcurrent” error message
will display. Cycling the key switch to “OFF”
and then to the “ON” position will clear the
fault.
2.
System Overvoltage>16VDC
If the voltage exceeds 16 volts, the system
will disengage the clutch and display
a “System Overvoltage>16VDC” error
message.
3.
System Undervoltage<9VDC
If the voltage is less than 9 volts, the
system will not allow clutch engagement
and will display the error “System
Undervoltage<9VDC”. If the clutch was
engaged before the error occurred, the
system will allow the clutch to remain
engaged; however, low voltage may cause
the clutch to disengage itself.
4.
Low Oil Pressure
If low engine oil pressure is detected, the
system will limit engine speed to the default
Efficient Transport Mode speed and place
the machine in “Safe Transport Mode”. Safe
Transport Mode limits the engine speed,
locks out the PTO, and disengages the
clutch; a “Low Oil Pressure” message will
display. Cycling the key switch to “OFF” and
then to the “ON” position will clear the fault.
5.
Engine Over Temperature
When the engine begins to overheat, the
system will flash the engine temperature bar
graph and chirp the audible alarm. If the
temperature rises above the upper limit, the
system will restrict the engine speed to the
default Efficient Transport Mode speed and
place the machine in “Safe Transport Mode”.
Safe Transport Mode limits the engine
speed, locks out the PTO, and disengages
the clutch; an “Engine Over Temperature”
message will display. The fault will clear
once the temperature falls below a safe limit.
