LMV
Standardize (O)
Sets a datum for a "normal" flame, so that a "normal" flame can be displayed as 100% flame
signal on the OperationalStat screen. If an 82.3% flame is present and the flame
standardization is performed, what was displayed as 82.3% is now displayed as 100%. This
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.
StandardFactor (O)
XXXX%
(Not Set)
0-100%
Can be viewed to see what percent raw flame signal will result in 100% flame signal being
displayed on the OperationalStat screen. If the flame signal is not standardized, XXXX % will
appear, indicating actual flame strength is displayed.
FlameSig QRI_B (U)
This can be viewed to see the raw flame signal (in %) from the flame scanner (IR or UV).
Flame failure at 20%. This signal refers to INPUT terminal X10-02.1 or X10-02.2.
FlameSig ION (U)
This can be viewed to see what raw flame signal (in %) is being sent to the LMV5 by an
ionization probe (flame rod) on terminal X10-03.1. The LMV5 will alarm when this value is
less than about 20%.
SensExtranlGas (O) 1 Sensor

Description
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
to be registered.
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.
x x
SensPilotPhGas (O) 1 Sensor See Above
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
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.
x x
SensOperPhGas (O) 1 Sensor See Above
For the LMV52, this defines how the main flame for gas firing is supervised. Options 1 thru 7
as described in parameters SensExtranlGas and SensPilotPhGas also apply to this
parameter.

NOTE: On an LMV52, it is recommended to set the following six flame scanner parameters for "1 Sensor". These parameters are unavailable on an LMV51.
