NOTE
1
If the system enters pendulum mode with LMV.. / ETAMATIC, adjust parameters
34.090
and
34.091
by increasing them, in
particular parameter
34.090
, in steps of 100mA/rad/sec.
NOTE
2
With LMV 2x/3x with INVERTER control, the device controls the standby rpm with
param. 653
.
If, after the fan is switched off, the device LMV 2x/3x sees that the motor continues to run, error
83
diagnostic
32
appears. This occurs if there is significant fan inertia (e.g. on burners with very heavy forward curved blades), then always
disable parameter 653, setting it to
0
.
NOTE
3
With LMV 2x/3x the signal 0-10V for motor rpm control during standardisation is brought to approximately 9.7 V and the
fan motor rpm is saved.
According to the LMV manual, the INVERTER should be set to max 52.5 Hz
During standardisation, the INVERTER is driven at approximately 51 ÷ 51.5 Hz and may go out of absorption range with
the motor.
For this reason, set the INVERTER to max 51.5 Hz.
During standardisation, the INVERTER will reach 50Hz and the over-absorption problem will be reduced.
NOTE
4
If the analogue wire break fault is displayed on the INVERTER and the 4-20 mA inverter signal continues to
oscillate between 1 ÷ 6 mA, it does not always mean that the LMV 2x/3x or ETAMATIC equipment is faulty. It could
be due to the old firmware of the INVERTER and should therefore be updated. If this is the case, contact the Service
Centre.
FAULTS / PROBLEMS.. SOLUTIONS
Parameter 36.020
If error 36 appears
Problems detected in the mains supply. By setting this
parameter to 0, the INVERTER no longer checks the
mains and the error message disappears. It is
recommended to leave the parameter set to 1.
Parameter 33.105
If mains voltage drops during operation
When the mains voltage drops, the INVERTER decreases
the motor rpm.
To reduce this change, set the parameter to 0, which
should solve the problem.
