Configures LMV5 INPUT X60 for a PT1000 ambient air temperature sensor. Sensor is not
required for O2 trim, but is required for the efficiency calculation. Ambient air temperature
sensor can be wired into terminal X60 of the LMV5 instead of the PLL module if X60 is not
being used for other temperature sensors.
Configures the PLL module for the appropriate flue gas temperature sensor. Sensor is not
required for O2 trim, but is required for the efficiency calculation.
Maximum flue temperature setpoint for each fuel. A warning will appear if temperatures
exceed this setting. PLL52 module must have a flue gas sensor wired in for this function.
This displays the current O2 value. O2 measured on a wet basis.
This displays the O2 setpoint at any operating point. This is the target for the O2 trim.
This displays the current ambient air temperature.
This displays the current flue gas temperature.
This displays the current combustion efficiency. If the O2 sensor is deactivated, this number
will not be displayed. Also, the flue and ambient temperatures are needed for this number to
display.
This displays the current O2 sensor internal temperature. Absolute minimum operating
temperature = 1202 F. Normal operating temperature for QGO20 is approximately 1292 F.
This displays the current heating load for the O2 sensor. The PLL serves as the temperature
control for the QGO20 sensor. Maximum heating load is 60%.
This measures the resistance of the O2 sensor. As a sensor is used, the resistance increases.
New sensors have a resistance of approximately 5 ohms. A reading of 0 ohms indicates that
a self-test has not been performed after a power off of the LMV5. When this value exceeds
150 ohms, the sensor should be replaced.
