Troubleshooting

Any # TUV test A fault occurred during the TUV test. See diagnostic codes for more information.
1 (-1) Invalid phase
The TUV test can only be started in phase 60 (operation). Reset the fault. When the LMV3
reaches phase 60, attempt to start the TUV test again.
2 (-2) TUV test default output too low
The TUV test default output (parameter 133/134) cannot be set lower than the lower load
limit (parameter 545/565). Either increase the TUV test default output or decrease the
lower load limit, then reset the fault.
3 (-3) TUV test default output too high
The TUV test default output (parameter 133/134) cannot be set higher than the upper load
limit (parameter 546/566). Either decrease the TUV test default output or increase the
upper load limit, then reset the fault.
4 (-4) Manual interruption No fault: The TUV test was aborted manually by the user.
5 (-5) TUV test timeout
There was no loss of flame after shutdown of the fuel valves. Check for extraneous light or a
faulty flame scanner, then reset the fault and start the TUV test again.

Any # Trim function: Invalid analog value
An invalid 4-20 mA signal was detected on input X64. Check the wiring to terminal X64.
Check the value of parameter 916. A value under -16% indicates <4 mA is being
detected, while a value over 26% indicates >20 mA is being detected.

Any #
Trim function: Invalid curve setting of
VSD / PWM blower
The following equations set the limits on the curve settings for the VSD / PWM blower.
Fuel 0: Parameter 669:00 + parameter 547 curve point parameter 669:01 -
parameter 548
Fuel 1: Parameter 669:00 + parameter 567 curve point parameter 669:01 -
parameter 568
1-9 Minimum value VSD curve invalid
A VSD curve point is below the permissible minimum value (diagnostic code = point
number, example: 1 = point P1)
21-29 Maximum value VSD curve invalid
A VSD curve point is above the permissible maximum value (diagnostic code = point
number, example: 21 = point P1)
41-49 Fuel 1: Minimum value VSD curve invalid Fuel 1: A VSD curve point is below the permissible minimum value (diagnostic code =
point number, example: 41 = point P1)
61-69
Fuel 1: Maximum value VSD curve
invalid
Fuel 1: A VSD curve point is above the permissible maximum value (diagnostic code =
point number, example: 61 = point P1)
156
Any #
Trim function: Maximum time for trim
limit exceeded
A trim limit was met for the maximum allowable time. See diagnostic codes for more
information.
0 Lower limit trim function
The VSD trim signal was lower than allowed by the minimum trim limit (parameter 547) for
a time period longer than the maximum time allowed (parameter 551).
1 Upper limit trim function
The VSD trim signal was higher than allowed by the maximum trim limit (parameter 548)
for a time period longer than the maximum allowed (parameter 551).
10 Fuel 1: Lower limit trim function
The VSD trim signal was lower than allowed by the minimum trim limit (parameter 567) for
a time period longer than the maximum time allowed (parameter 571).
11 Fuel 1: Upper limit trim function
The VSD trim signal was higher than allowed by the maximum trim limit (parameter 568)
for a time period longer than the maximum allowed (parameter 571).
157
Any # Trim function: Failed the analog input test A fault occurred during the analog input test. See diagnostic codes for more information.
0 Analog value standby
If the analog input test is enabled, the LMV3 looks for 12mA to be present on terminal X64
during standby. Check parameter 916 to ensure that the input signal lies in the permissible
range of -1%...+1%. Setting parameter 530 to a value other than 2 or 4 disables the
analog input test.
1 Analog value prevention
If the analog input test is enabled, the LMV3 looks for 4mA to be present on terminal X64
during prepurge. Check parameter 916 to ensure that the input signal lies in the
permissible range of -16%...-14%. Setting parameter 530 to a value other than 2 or 4
disables the analog input test.
