2 Limitation of upper adjustment range The rpm value of the frequency converter was too low.
84 # Actuator curve steepness
Bit 0
Significance 1
Frequency converter: curve too steep
compared to gas train speed
Check the rpm difference between basic point and setting of the
operating gas train in modulation (parameter 544).
Operating gas train in 32 second modulation. Slope of the curve
maximum 10% with gas train LMV37.4 of 20 seconds (20% with
10 seconds or 40% with 5 seconds).
Operating gas train in 48 second modulation. Slope of the curve
maximum 10% with gas train LMV37.4 of 30 seconds (20% with
15 seconds or 30% with 10 seconds).
Operating gas train in 64 second modulation. Slope of the curve
maximum 10% with gas train LMV37.4 of 40 seconds (20% with
20 seconds or 40% with 10 seconds). Between the ignition point
(P0) and the low flame (P1), the variation of the rpm value in
modulation can be 40%, independent of the LMV gas train.
The gas train of the frequency converter must be set approx.
20% faster than the gas trains of the appliance (parameter: 522,
523).
Bit 1
Significance 2-3
Fuel operation: too steep curve
compared to gas train speed
Check the position difference between basic point and setting of
the operating gas train in modulation (parameter 544).
Operating gas train in 32 s modulation. The slope of the curve
must be max. 31° (15° with SQM33.6 or 9° with SQM33.7)
of position change between 2 basic points in modulation
operating mode.
Operating gas train in 64 s modulation. The slope of the curve
must be max. 62° (30° with SQM33.6 or 18° with SQM33.7)
of position change between 2 basic points in modulation
operating mode.
Bit 2
Significance 4-7
Air drive: too steep curve compared
to gas train speed
Check the position difference between basic point and setting of
the operating gas train in modulation (parameter 544).
Operating gas train in 32 s modulation. The slope of the curve
must be max. 31° (15° with SQM33.6 or 9° with SQM33.7)
of position change between 2 basic points in modulation
operating mode.
Operating gas train in 64 s modulation. The slope of the curve
must be max. 62° (30° with SQM33.6 or 18° with SQM33.7)
of position change between 2 basic points in modulation
operating mode.
85 # Reference error of an actuator
0 Reference error of a fuel drive
Fuel drive referencing not successfully completed. The reference
point could not be reached.
-Check the setting of the type of drive (parameter 613.0 or 614)
-Check if the actuator have been mixed up.
-Check whether the actuator is stuck or overloaded.
1 Reference error of the air drive
Air drive referencing not successfully completed. The reference
point could not be reached.
-Check the setting of the type of drive (parameter 613.1).
-Check if the actuator have been mixed up.
-Check whether the actuator is stuck or overloaded.
Bit 7
Significance ≥ 128
Reference error for parameter editing
The parametrisation of an actuator (i.e. status of the reference
position) has been edited. This error is generated to provoke a
new referencing.
#
86 # Fuel drive error
0 Position error
The requested position could not be reached within the defined
tolerance. Check whether the actuator is stuck or overloaded.
240 # Internal error Unlock, if it occurs again replace the appliance.
245 # Internal error Unlock, if it occurs again replace the appliance.
250 # Internal error Unlock, if it occurs again replace the appliance.
