SpecialFeaturesandSettings

The LMV5 has special features and settings that are very useful in some situations. Some of these
featuresaredetailedbelow.

Alarmact/deact Aninternalalarmsilence.AlarmsilencewillresetwhentheLMV5alarmisreset.

MinTmeStartRel PermitstheLMV5toholdinphase21foraspecifiedperiodoftimewiththestart
signalterminalenergized.Thiscanbeusedasadelaytoletstackand/orfreshair
dampersopen.

PressReacTme Allows the LMV5 to disregard the high and low gas / oil pressure switches for a
settable time period after the main gas / oil
 valves open.This is used with
automaticresetpressureswitchessothatpressurespikes duetothemainvalves
opening will be ignored.This also allows  for a reduced delta between switch
setpoints and normaloperatingpressures.Thistimecanalsobe
 reduced to0.2
seconds,deactivatingthefeature.Notusedwithmanualresetswitches.

NormDirectStart Permits the LMV5 to go from post‐purge directly into pre‐purge without turning
thebloweroff.Theblowe r airpressureswitchmustbecheckedbyusinga3‐way
solenoidvalve.Thesolenoidvalveisconfiguredun
derparameterStartSignal.



Config_PS‐VP/CPI Configures terminal X9‐03.2 for PS‐VP (Pressure Switch‐Valve Proving), CPI gas,
