The factory-set response threshold is 40%. The display of the LT3-F shows whether or not the
response threshold has been reached. When the response threshold is reached, the CO edge
signal is present, and the CO regulation becomes active. This is indicated by a symbol on the
display of the LT3-F or can be exported via the LSB remote software of the LT3-F in pa-
rameter 444. The desired response threshold can be set on the display of the LT3-F or using
Parameter 453 of the LSB remote software of the LT3-F. Access level 2 is required for service!
Setting recommendation:
– For burners without a CO base level, the response threshold in the LT3-F should be set in
such a way that the CO edge is at 20  10 ppm CO (measured using a CO reference
measuring device).
– For burners without a CO base level, the response threshold value should be set to values
 80 ppm CO (measured using a CO reference measuring device).
– Setting increments 10%

8.10.8.1 Resetting Faults
Faults are reset in different ways:
Resetting temporary faults (ot):
The fault is displayed for as long as it is present. Once the cause of the fault is eliminated, the
fault is deleted, and the fault status signal no longer displayed.
Resetting permanent faults (od) at startup of the burner:
Each time the burner starts up, a fault is automatically reset, even if the cause of the fault has
not yet been eliminated. If the cause has not yet been eliminated, the fault will re-occur.
Resetting permanent faults (od) manually:
You can also reset permanent faults (od) manually after eliminating the cause.
UI400: Open the fault status signal using the arrow keys (see chapter Calling the CO/O

CMS Remote Software: Use the RESET buttons in the header bar of the CMS Remote Soft-
ware.
