Code Fault
Operator/Field Fix
Technical/Diagnostic Fix
TR/TL 38
Main Contactor Welded Main contactor failure
1. Main contactor tips are welded closed.
2. Motor phase U or V is disconnected or open.
3. An alternate voltage path (such as an external
precharge resistor) is providing a current to
the capacitor bank (B+ connection terminal).
TR/TL 39
Main Contactor Did
Not Close
Main contactor failure
1. Main contactor did not close.
2. Main contactor tips are oxidized, burned, or
not making good contact.
3. External load on capacitor bank (B+
connection terminal) that prevents capacitor
bank from charging.
4. Blown B+ fuse.
TR/TL 41
Throttle Wiper High
1. Throttle failure.
2. Check the connections of
Throttle.
1. See Monitor menu >> Inputs: Throttle Pot.
2. Throttle pot wiper voltage too high.
3. Bring throttle pot wiper voltage below the
fault threshold.
TR/TL 42
Throttle Wiper Low
1. Throttle failure.
2. Check the connections of
Throttle.
1. See Monitor menu >> Inputs: Throttle Pot.
2. Throttle pot wiper voltage too low.
3. Bring throttle pot wiper voltage above the
fault threshold.
TR/TL 43
Pot2 Wiper High
1. Electric Putter (Electric
height adjustment module)
sensor failure;
2. Check the connections of
Electric Putter.
1. See Monitor menu >> Inputs: Pot2 Raw.
2. Pot2 wiper voltage too high.
3. Bring Pot2 wiper voltage below the fault
threshold.
TR/TL 44
Pot2 Wiper Low
1. Electric Putter (Electric
height adjustment module)
sensor failure;
2. Check the connections of
Electric Putter.
1. See Monitor menu >> Inputs: Pot2 Raw.
2. Pot2 wiper voltage too low.
3. Bring Pot2 wiper voltage above the fault
threshold.
TR/TL 45
Pot Low Overcurrent
1. Electric Putter (Electric
height adjustment module)
sensor failure;
2. Check the connections of
Electric Putter.
1. See Monitor menu >> Outputs: Pot Low.
2. Combined pot resistance connected to pot
low is too low.
TR/TL 46
EEPROM Failure
Cycle KSI.
Download the correct software (OS) and match-
ing parameter default settings into the controller
and cycle KSI.
TR/TL 47
HPD/Sequencing Fault Reapply input s in correct
sequence.
1. KSI, interlock, direction, and throttle inputs
applied in incorrect sequence.
2. Faulty wiring, crimps, or switches at KSI,
interlock, direction, or throttle inputs.
3. See Monitor menu >> Inputs.
TR/TL 47
Emer Rev HPD
Reapply input s in correct
sequence.
At the conclusion of Emergency Reverse, the
fault was set because various inputs were not
returned to neutral. If EMR_Interlock = On, clear
the interlock, throttle, and direction inputs. If
EMR_Interlock = Off, clear the throttle and
direction inputs.
