function (manual interruption of 4...20 mA analog input)
61 Fuel Chg
#
Fuel changeover
Fuel Chg
0
Fuel 0
No error - change to Fuel 0
Fuel Chg
1
Fuel 1
No error - change to Fuel 1
62 Fuel Err
#
Invalid fuel signals / fuel information
Fuel Err
0
Invalid fuel selection (Fuel 0 + 1 = 0)
Check wiring to see if there is an open-circuit
Note
Curves cannot be set
Fuel Err
2
Different fuel signals between the µCs
Make a reset; if error occurs repeatedly, replace the unit
Fuel Err
3
Invalid fuel selection (Fuel 0 + 1 = 1)
Check wiring for short-circuit
Note
Curves cannot be set.
LMV36...: Optional press reset button >3 seconds.

positions
reached
Can be caused by different standardized speeds (e.g. after restore of data set) when the VSD is
activated
standardize again and check adjustment of the fuel-air ratio control system

Internal error fuel-air control
Make a reset; if error occurs repeatedly, replace the unit
80
#
Control range limitation of VSD
Basic unit could not correct the difference in speed and reached a control range limit.
