Default
Range
Sets the time that the LMV5 will ignore the high and low gas pressure switch inputs after the
0.2-Max
main gas valves open. This is done so that pressure shocks do not cause erroneous alarms on
2s
SafetyTGas
properly adjusted high or low automatic reset gas pressure switches. Does not work with
manual reset switches.
The allowable time to let the LMV5 achieve low fire shutdown after a call for heat is removed
45s
0.2-630s
via internal load controller or INPUT X5-03.1. Setting does not affect fuel valve closing in the
event of a safety shutdown.
Defines the permissible time for a flame to be detected after the main fuel valves are closed
8s
0.2-63s
without causing a startblock or alarm. Useful for air postpurged oil nozzles.
30s
Defines the mandatory postpurge period. Even if the direct start option is selected and a call
0.2s-63min
for heat exists, the LMV5 will only go into prepurge after this period times out.
30s
5s
Defines an optional postpurge period. If the direct start option is selected and a call for heat
0.2s-63min
exists, the LMV5 will go directly into prepurge after PostpurgeT1Gas(Oil) .
5s
Defines a postpurge time that is in addition to PostpurgeT3Gas(Oil) . If the direct start
0min
0-65535min
option is selected and a call for heat exists, the LMV5 will go directly into prepurge after
PostpurgeT1Gas(Oil) expires.
1s
0.2-63s
The minimum time the LMV5 will wait in phase 10 before proceeding to phase 12.
If there is a lack of gas pressure (low gas pressure switch open), then the LMV5 will wait this
period of time before attempting to relight, provided that the repetition counter
MinTmeHome
10s
RepetitCounter for gas is set for more than one (not done in the US). This time period will
Run -63s
double after the first relight attempt. This doubling would occur if RepetitCounter were set
to 3 or greater. Cannot be set for a shorter time than MinTmeHomeRun .
If a condition exists that does not open the safety loop but does prevent the LMV5 from
starting when there is a call for heat, this specifies the period of time that can elapse with
10s
0.4-630s
this condition before the alarm is energized. If AlarmStartPrev (alarm in the case of start
prevention) is deactivated, setting this time has no effect.
Period of time before a start prevention is displayed on the AZL. When there is a call for heat,
and a start prevention occurs that does not open the safety loop but does prevent the LMV5
0.4s
0.4-630s
from starting, this specifies the period of time that can elapse before the condition is
displayed on the AZL.
