Error
code
Diagnostic code Meaning for the LMV36... system Remedy
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.
66 # Internal error
Make a reset; if error occurs repeatedly, replace the unit
67 # Internal error
Make a reset; if error occurs repeatedly, replace the unit
70 #
Internal error fuel-air ratio control: Position calculation
modulating
23 Output invalid No valid output
26 Curvepoints undefined Adjust the curvepoints for all actuators
71 # Special position undefined
0 Home position Parameterize the home position for all actuators used
1 Prepurge position Parameterize the prepurge position for all actuators used
2 Postpurge position Parameterize the postpurge position for all actuators used
3 Ignition position Parameterize the ignition position for all actuators used
72 # Internal error fuel-air ratio control
Make a reset; if error occurs repeatedly, replace the unit
73 #
Internal error fuel-air ratio control: Position calculation
multistep
23 Output invalid No valid output
26 Curvepoints undefined Adjust the curvepoints for all actuators
75 # Internal error fuel-air ratio control: Data clocking check
1 Current output different
2 Target output different
4 Target positions different
16 Different 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
76 # 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.
