Default Range
Sets the function of INPUT X6-01.3.
1) 38/44..62 - input must be energized in phase 38 and / or 44, and during phases 50 thru 62.
38/44..62
2) act 21..62 - input must be energized for phase 21 thru 62. This setting is useful for a low
act 21..62
oil temperature switch.
HTempGuard
38/44..62 3) HTempGuard - only used on an LMV50.
ext.FlameGd
4) ext.FlameGd - input is used for a flame signal from an external flame safeguard. If used,
deactivated
no flame detector may be connected to terminal X10.
activ 38/44
5) deactivated - terminal has no function.
6) activ 38/44 - input must be energized in phase 38 or 44.
Sets the function of OUTPUT X4-03.3.
1) StartSignal - output is energized from phase 21 (before the blower) thru phase 78 (after
postpurge), and is suited to open an outside air or stack damper. If ContinuousPurge is
activated, this terminal will be energized with the fan.
StartSignal
2) PS Relief - wired to a 3-way valve used to check the action of combustion air pressure
Start Signal PS Relief
switch and is necessary if direct start is used. Energizing vents the combustion air pressure
PS Reli_Inv
switch to atmosphere during phase 79.
3) PS Reli_Inv - the action is opposite of PS Relief mode, thus de-energizing vents the
combustion air pressure switch to atmosphere during phase 79, and the 3-way valve is
energized during operation.
If the extraneous light test is activated (see next parameter), this setting determines the
Startblock response to extraneous light.
Startblock
Lockout 1) Startblock - will not permit a start of the lightoff sequence.
2) Lockout - lockout in response to extraneous light.
Activates or deactivates the extraneous light check during the start sequence and during
activated
activated standby. NOTE : This setting is intended to be used with applications such as waste
deactivated
incinerators. DO NOT deactivate for boiler burners.
Sets the flame failure reaction time. The LMV5 has a base flame failure reaction time of
0.2s 0.2-3.2s approximately 0.8 seconds, so the setting of this parameter will add to the base flame failure
reaction time. Max total flame failure reaction time is 4 sec.
