45
48 Vdc Bus
Overvoltage -
System
Cutting unit
This fault is reported when all 4
individual 48 Vdc bus circuit high
voltage alerts are active at the
same time.
This is indicative of a
starter/generator
issue, like a bad
charger or having the
wrong batteries
attached. Individual
components reporting
typically point to a
voltage regulator
issue.
The TEC will disable
the cutting units
(PTO), and the
generator will not
provide voltage.
1) Test the battery voltage.
2) Inspect the battery terminal
connections.
3) Test the internal S/G
connections.
4) Test the S/G for proper function.
46
48 Vdc Logic
(Keyswitch)
Overvoltage -
System
Cutting unit
This fault is reported when all 4
individual 48 Vdc logic
(keyswitch) high voltage alerts
are active at the same time.
This is indicative of a
starter/generator
issue, like a bad
charger or having the
wrong batteries
attached. Individual
components reporting
typically point to a
voltage regulator
issue.
1) Test the battery voltage.
2) Inspect the battery terminal
connections.
3) Test the internal S/G
connections.
4) Test the S/G for proper function.
47
Overtemp Bulb –
Current Too High
Master
This fault is reported when the
overtemp bulb’s circuit voltage is
too high.
1) Check that output circuit 11 is
not shorted.
2) Replace the master TEC if the
fault continuously repeats.
49
Fault Latch – Phase
Overcurrent
Starter/Generator
The current sensor on phase
current will trigger this fault
when 240 amps are sensed.
The TEC will disable
the cutting units
(PTO), and the
generator will not
provide voltage.
The contactor will not
close.
Replace the starter/generator
controller if the fault
continuously repeats.
