Information concerning the VSD board (pieces internal to the LMV)
U
Software version of the VSD.
This defines what O2 sensor is used with the PLL52 module. QGO20 Max. flue gas temp 572 deg F Range
= No sensor, QGO20, Def = No Sensor, Typ = QGO20
This sensor connects to the PLL module and is necessary for the boiler efficiency calculation. Range = No
sensor, Ni1000, Pt1000, Def / Typ = Ni1000
This sensor connects to the PLL module and is necessary for the boiler efficiency calculation. Range = No
S
sensor, Ni1000, Pt1000, Def / Typ = Pt1000 NOTE : If configured for Pt1000, any 1000 ohm Platinum RTD
having a temperature coefficient of 385 will be accurate. Resistance of the correct RTD is 1000 ohms @
32F.
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. PLL52 mod le m st ha e a fl e gas sensor ired in for this f nction
Range = 32 deg F to 752 deg F Def = 32 def F, Typ = boiler specific
This displays the current wet O2 values in the flue.
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 combustion efficiency. If the O2 sensor is deactivates, this number will not be
displayed. Also the flue and ambient temperatures are needed for this number to display.
This displays the current flue gas temperature.
U
This displays the current O2 Sensor temperature. Absolute minimum operating temperature = 1202
This displays the current heating load for the O2 Sensor. The PLL regulates the heating voltage to 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 0 ohms.
When this value exceeds 100 ohms, sensor should be replaced the next time the burner is serviced.
Absolute maximum is 150 ohms.
