Device Display Meaning for the LMV5x System Corrective Action
Any # (Internal) communication error of ELV
3F Detection of different data when making the data comparison
01
Timeout with program synchronization prior to data
transmission
02 Timeout with data transmission
03 CRC fault during data transmission
18 Any #
Invalid Curve
Data
Corruption in the combustion curve data
Values on curve should be within 0.0% - 100.0% for
load and VSD, 0.0° - 90.0° for actuators. If possible,
adjust curve values back into the valid range. If this
fault occurs on a unit that was functioning correctly after
commissioning, replace LMV5.
Any #
Basic unit (ratio control system) has detected a fault
when comparing potentiometer channels A and B. Diagnostic
code shows on which actuator the fault occurred. See
diagnostic code.
01..2F
The diagnostic value is made up of the following faults or their
combinations (the individual diagnostic codes are added up in
hexadecimal format)

If fault occurs sporadically, reduce electrical noise.
If fault occurs continuously, replace LMV5.

1) If fault occurs constantly: Replace actuator according
to diagnostic code. If a solid coupling was being used
on the defective actuator, replace with a flexible
coupling. After actuator(s) are replaced, make sure that
the actuators do not "hunt" during operation. This can
be done by adjusting parameter MinActuatorStep and
the PID loop.
Fault with Base Unit (LMV5)
Fault occurred on the individual actuator (see diagnostic code)
when comparing potentiometer channels A and B
