O Sets the numer of recycles in the event of a flame failure. Range = 1 or 2. Def / Typ = 1
Sets how many times the LMV will attempt to proceed past Phase 21 if a start release for heavy oil is not
met. After this number if tries, a lockout will occur. Range = 1 to 16 Def / Typ = 1

such as a fresh air damper or low gas pressure on INPUT terminal
X9-03.04. After this number if tries, a lockout will occur. Range = 1 to 16 Def / Typ = 1
This parameter should always be set to 1. Def = 1
This determines if gas valve proving (leak testing) will be performed. Gas valve proving can be performed
on start-up, shutdown, or both. If "No VP" is selected, valve proving will not be performed.
Range = VP shutdown, VP Startup, No VP, VP Stup/shd, Def / Typ = No VP
INPUT X9-03.02 has multiple functions, depending upon how this parameter is set. On a LMV51 it can be
set for either CPI (proof of closure) for gas or PS-VP, which is a pressure switch for gas valve proving. Oil
proof of closure switches are not intended to be wired to this terminal on a LMV51. On a LMV52, options are
PS-VP, CPI oil, CPI gas, or CPI gas and oil. Usually configured for CPI (proof of closure) on gas valves.
Access to this same parameter is also available under : Params & Display> BurnerControl> Configuration>

used, opening times of the gas valves must be less than the maximum value for this parameter. Range =
O 0.2 to 10 sec Def / Typ = 3 sec
If valve proving is enabled, this is the time that both the upstream and downstream valves are closed. If the
pressure rises between the valves during this period (enough to open the N.C. pressure switch), then the
upstream valve is leaking and the LMV will lockout. A longer time period will produce a more sensitive test.
Range = 10 to 63 sec, Def / Typ = 10 sec
If valve proving is activated, this specifies the time that the upstream valve (V1) is energized (OUTPUT
X9.01.04). This will fill the volume between the main gas valves to line pressure. Note: If gas valve proving is
to be used, opening times of the gas valves must be less than the maximum value for this parameter. Range
= 0.2 to 10 sec, Def / Typ = 3 sec
If valve proving is enabled, this is the time that both the upstream and downstream valves are closed. If the
pressure falls between the valves during this period (enough to close the N.C. pressure switch), then the
downstream valve is leaking and the LMV will lockout. A longer time period will produce a more sensitive
test. Range = 10 to 63 sec, Def / Typ =10 sec
