This fault is reported when the
TEC sensed the engine
temperature to be beyond
115 ºC (240 ºF) for more than 10
seconds.
This fault is for diesel
engine-equipped units
only.
The TEC will shut the
engine down to
prevent damage.
1) Allow the machine to cool off for
30 minutes.
2) Check the coolant level.
3) Check the cooling fan for proper
function.
4) Inspect the radiator airflow
passageways to ensure they are
clear of debris.
5) Test the temperature sender
wiring.
6) Test the coolant temperature
sender for proper function.

48 Vdc Logic
(Keyswitch)
Undervolt – CU1
Cutting unit
This fault is reported when the
48 Vdc system voltage drops
below 32 Vdc at cutting unit 1.
The TEC will shut the
cutting units (PTO)
down.
1) Check all 48 Vdc fuses.
2) Check the logic power
connection to the cutting unit
motor.
3) If more than one device is
reporting this fault, check the
battery voltage with the engine
off.
4) If the battery voltage is ok with
engine off, but not when the
engine is running, test the S/G
for proper generator function.

48 Vdc Logic
(Keyswitch)
Undervolt – CU2
Cutting unit
This fault is reported when the
48 Vdc system voltage drops
below 32 Vdc at cutting unit 2.
The TEC will shut the
cutting units (PTO)
down.
1) Check all 48 Vdc fuses.
2) Check the logic power
connection to the cutting unit
motor.
3) If more than one device is
reporting this fault, check the
battery voltage with the engine
off.
4) If the battery voltage is ok with
engine off, but not when the
engine is running, test the S/G
for proper generator function.
