Enables or disables INPUT X3-02.01, the air pressure switch (fan air switch), during any phase that the fan
is running. Enable for forced or induced draft burners. Def / Typ = Activated
INPUT X9-03.02 has multiple functions, depending upon how this parameter is set.
An LMV51 options are CPI (proof of closure for gas), or
PS-VP, (Pressure Switch for gas Valve Proving). Default : PS-VP
Oil proof of closure switches are not intended to be wired to this terminal on a LMV51.
An LMV52 options are PS-VP, CPI oil, CPI gas, or CPI gas and oil.
Typically configured for CPI gas (proof of closure on gas valves). Def = PS-VP
Set at: Params & Display > BurnerControl > ValveProving > Config_PM-VP/ CPI
Enables or disables INPUT X4-01.03, checking the status of fan motor starter,
or a flue gas recirculation pressure switch. (checked on both gas and oil firing)
Phase affected is any phase when the fan is running. Range: FGR-PS, FCC, deactivated
Usually set to monitor auxiliary fan motor starter contacts (FCC) Def = FCC
This can be used with the internal load controller as a overall enable / disable,
O
even if the internal load controller is calling for heat. In other words, the ON /OFF switch.
Activated, the LMV requires power on INPUT terminal X5-03.01 to begin its operating sequence. A Activated the LMV requires power on INPUT terminal X5-03 01 to begin its operating sequence A
traditional "string" of switches, including the on /off switch could be wired in between line voltage to
X5.03.01, and the LMV would begin when these switches are made.
Activate if the burner has a hard wired on / off switch.
Deactivated, the LMV does not need require power on INPUT terminal X5-03.01 to begin its sequence.
This may be done if the burner is controlled via ModBus. Def / Typ = Activated
Determines the function of INPUT terminal X9-03.04.
In Activated mode, a signal is expected on this terminal when firing gas, or when using any oil train that
requires a pilot. Thus, when in Activated mode, with a piloted oil train, this terminal can be used for a general
start release, like a fresh air damper. Deact x OGP mode, a signal is expected only when firing gas, so a
start release specific to gas can be wired in series with the low gas pressure switch. Can also be
deactivated. Def = Activated
Deact x OGP is only offered on the LMV52.
Activates or deactivates (INPUT X9-03.03) for a high gas pressure switch.
Most gas fired installations require high a gas pressure switch. Def = Activated
