Display
Internal Fault Actuator The diagnostic value is made up of the fol-
lowing faults or their combinations (the in-
dividual diagnostic codes are added up in
hexadecimal format)
Internal Fault Actuator Fault occurred on the air actuator when
comparing potentiometer channels A and
B
Internal Fault Actuator Fault occurred on the active fuel actuator
when comparing potentiometer channels A
and B

Slope too steep Slope of curve section is too steep
Operation in Parameter Setting Programming mode is still active in Phase
Mode quit 62 and the target positions (normal opera-
tion) have not been reached
Ignition Pos not defined The relevant ignition positions have not
been parameterized
Meaning for the LMV5x system Troubleshooting

Check curve data. If there is a slope greater than
- 3.6° per 0.1 % (30 s ramp)
- 1.8° per 0.1 % (60 s ramp)
- 0.9° per 0.1 % (120 s ramp)
load change between 2 curvepoints -> change load as-
signment of the curvepoints such that above condition will
be satisfied
When parameterizing the curve, the plant should be oper-
ated in manual mode with "Burner on". This prevents the
load controller from triggering the change to shutdown. Re-
sponse of the TL can trigger the same action, however, but
the value (curvepoint) currently handled can still be stored
in standby or lockout
Set the ignition positions
