105
Over Current
Disable – CU2
Cutting unit
This fault is reported when the
hardware in CU2 detects an
overcurrent condition and
disables the PWM to stop the
motor. This happens when the
FET current is measured in
excess of a design limit set
point.
This can be reported
as hardware
overcurrent or
overvoltage. This fault
exists to protect this
system in case the SW
does not limit the
current and voltage
correctly.
The TEC will disable
the cutting units
(PTO).
Replace the cutting unit motor.
106
Over Current
Disable – CU3
Cutting unit
This fault is reported when the
hardware in CU3 detects an
overcurrent condition and
disables the PWM to stop the
motor. This happens when the
FET current is measured in
excess of a design limit set
point.
This can be reported
as hardware
overcurrent or
overvoltage. This fault
exists to protect this
system in case the SW
does not limit the
current and voltage
correctly.
The TEC will disable
the cutting units
(PTO).
Replace the cutting unit motor.
111
Internal Regulator
Overvolt – S/G
Cutting unit
This fault is reported when the
component measures 15 Vdc
system voltage in excess of 14.5
Vdc.
The TEC will disable
the cutting units and
the generator will not
provide voltage.
Replace the S/G controller if the
fault continuously repeats.
112
Internal Regulator
Undervolt – CU1
Cutting unit
This fault is reported when
system voltage drops below the
8.5 Vdc minimum. This fault will
disable the motor.
The TEC will disable
the cutting units.
Replace the cutting unit motor.
113
Internal Regulator
Undervolt – CU2
Cutting unit
This fault is reported when
system voltage drops below the
8.5 Vdc minimum. This fault will
disable the motor.
The TEC will disable
the cutting units.
Replace the cutting unit motor.
