Default Range
For the LMV52, this defines how the combustion chamber will be supervised during the
1 Sensor See Above period when the fuel valves are closed (oil firing).
Options 1 thru 6 as described in parameter SensExtranlGas apply to this parameter.
For the LMV52, this defines how the pilot for oil firing is supervised. Options 1 thru 7 as
1 Sensor See Above
described in parameters SensExtranlGas and SensPilotPhGas also apply to this parameter.
For the LMV52, this defines how the main flame for oil firing is supervised. Options 1 thru 7
1 Sensor See Above as described in parameters SensExtranlGas and SensPilotPhGas also apply to this
parameter.
Sets the number of times a flame failure is required to cause a lockout. Most US codes
1 1-2
require 1.
Sets how many times the LMV5 will attempt to proceed past phase 21 if a start release for
1 1-16 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.
Sets how many times the LMV5 will attempt to proceed past phase 21 if a start release is not
1 1-16 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.
Sets how many times the LMV5 will attempt to restart without manual reset when the safety
1 1-16 loop is opened. This parameter should always be set to 1. A setting of 16 indicates unlimited
repetitions.
No VP This determines if gas valve proving (leak testing) will be performed. Gas valve proving can
VP startup be performed on startup, shutdown, or both. If 'No VP' is selected, valve proving will not be
No VP
VP shutdown performed. If 'No VP' is selected, and parameter Config_PS-VP/CPI is set to PS-VP, then
VP stup/shd INPUT X9-03.2 is essentially deactivated.
Sets the function of INPUT X9-03.2. Functions: PS-VP (Pressure Switch - Valve Proving) for
PS-VP
use with automatic valve proving, proof of closure (POC) for gas valves, POC for oil valves, or
CPI Gas
PS-VP POC for gas and oil valves. Note: POC and CPI (Closed Position Indication) are the same
CPI Gas+Oil CPI
function. Input can be deactivated by setting to PS-VP and de-activating valve proving. The
Oil
same parameter is also available under : Params & Display > BurnerControl > Configuration
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
3s 0.2-10s
valves. Note: If gas valve proving is used, opening times of the gas valves must be less than
the maximum value for this parameter.
