parameter does not affect when a lockout occurs due to low flame signal. This standarization
is performed when a normal flame exists in the burner.

appear, indicating actual flame strength is displayed.
This can be viewed to see the raw flame signal (in %) from the flame scanner (IR or UV).
Read Only
Flame failure at 20%. This signal refers to INPUT terminal X10-02.1 or X10-02.2.
This can be viewed to see what raw flame signal (in %) is being sent to the LMV5 by an
Read Only
ionization probe (flame rod) on terminal X10-03.1. The LMV5 will alarm when this value is
less than about 20%.
For the LMV52, this defines how the combustion chamber will be supervised during the
period when the fuel valves are closed (gas firing).
The choices for supervision during this phase are as follows:
1) 1 Sensor: Either a flame rod (ION) or scanner can be connected and used. Both cannot be
connected.
2) QRI_B | ION: Both sensors can be connected. A flame signal on either will cause a signal

1 Sensor to be registered.
Description
3) QRI_B & /ION: Both sensors can be connected. Flame must be detected by QRI_B and not
ION.
4) QRI_B: Both sensors can be connected. Only QRI_B is used.
5) ION &/QRI_B: Both sensors can be connected. Flame must be detected by ION and not
QRI_B.
6) ION: Both sensors can be connected. Only ION is used.
For the LMV52, this defines how the pilot for gas firing is supervised. Options 1 thru 6 as
described in parameter SenExtranlGas also apply to this parameter. Additionally, there is
1 Sensor See Above one option added for this parameter. This option is:
7) QRI_B & ION: Both sensors can be connected. Both sensors must detect a flame at the
same time or a flame failure will occur.
For the LMV52, this defines how the main flame for gas firing is supervised. Options 1 thru 7
1 Sensor See Above as described in parameters SensExtranlGas and SensPilotPhGas also apply to this
parameter.
