LMV
SensExtranlOil (O) 1 Sensor See Above
For the LMV52, this defines how the combustion chamber will be supervised during the
period when the fuel valves are closed (oil firing).
Options 1 thru 6 as described in parameter SensExtranlGas apply to this parameter.
x x
SensPilotPhOil (O) 1 Sensor See Above
For the LMV52, this defines how the pilot for oil firing is supervised. Options 1 thru 7 as
described in parameters SensExtranlGas and SensPilotPhGas also apply to this parameter.
x x
SensOperPhOil (O) 1 Sensor See Above
For the LMV52, this defines how the main flame for oil firing is supervised. Options 1 thru 7
as described in parameters SensExtranlGas and SensPilotPhGas also apply to this
parameter.
x x
LossOfFlame (S) 1 1-2
Sets the number of times a flame failure is required to cause a lockout. Most US codes
require 1.
x x x
HeavyOil (S) 1 1-16
Sets how many times the LMV5 will attempt to proceed past phase 21 if a start release for
heavy oil is not met on INPUT X6-01.3. After this number of tries a lockout will occur. A
setting of 16 indicates unlimited repetitions.
x x x
StartRelease (S) 1 1-16
Sets how many times the LMV5 will attempt to proceed past phase 21 if a start release is not
met, such as low gas pressure on INPUT terminal X9-03.4. After this number of tries, a
lockout will occur. A setting of 16 indicates unlimited repetitions.
x x x
SafetyLoop (S) 1 1-16
Sets how many times the LMV5 will attempt to restart without manual reset when the safety
loop is opened. This parameter should always be set to 1. A setting of 16 indicates unlimited
repetitions.
x x x
ValveProvingType (O) No VP
No VP
VP startup
VP shutdown
VP stup/shd
This determines if gas v
alve proving (leak testing) will be performed. Gas valve proving can
be performed on startup, shutdown, or both. If 'No VP' is selected, valve proving will not be
performed. If 'No VP' is selected, and parameter Config_PS-VP/CPI is set to PS-VP, then
INPUT X9-03.2 is essentially deactivated.
x x x
Config_PS-VP/CPI (O) PS-VP
PS-VP
CPI Gas
Oil
Sets the function of INPUT X9-03.2. Functions: PS-VP (Pressure Switch - Valve Proving) for
use with automatic valve proving, proof of closure (POC) for gas valves, POC for oil valves, or
POC for gas and oil valves. Note: POC and CPI (Closed Position Indication) are the same
function. Input can be deactivated by setting to PS-VP and de-activating valve proving. The
same parameter is also available under : Params & Display > BurnerControl > Configuration
x x x
VP_EvacTme (O) 3s 0.2-10s
If valve proving is activated, this specifies the time that the downstream valve (V2) is
energized, OUTPUT X9-01.3. This will evacuate any gas that might exist between the gas
valves. Note: If gas valve proving is used, opening times of the gas valves must be less than
the maximum value for this parameter.
