Parameter Name
Fuel Train** Not set 1-29
Sets the fuel train. There are 29 options available. See section 4 for details about each option. Setting this
parameter to undefined (----) will delete any existing fuel curves.
Invalid Analog In 0 0-2
This sets the behavior of the LMV3 when the 4-20 mA signal on terminal X64 is out of range. On an LMV37,
this parameter has no effect unless "revert to pilot" is enabled via parameter 191.
0 = Drive to low fire or no VSD trim (warning message will be displayed)
1 = Lockout
2 = Drive to low fire or no VSD trim (no warning message will be displayed)
Staged Config O 0 0-1
Parameter only exists on an LMV37. Sets the behavior of terminal X5-03 pin 2 and pin 3 for staged
operation:
0 = standard
1 = stages interchanged
Program Stop 0 0-4
This parameter will stop the startup sequence in the selected phase. This is useful for commissioning and
service work. The LMV3 can be held in the following phases:
0 = deactivated
1 = phase 24 (prepurge position)
2 = phase 36 (ignition position)
3 = phase 44 (interval 1 - pilot stabilization)
4 = phase 52 (interval 2 - main stabilization)
Alarm Start Prevent 1 0-1
Determines if the alarm output X3-05.2 will be energized in the event of a start prevention (an alarm in
standby). The LMV3 will wait 5 seconds after receiving a call for heat before displaying the start prevention
on the AZL.
0 = deactivated
1 = activated
Fan Ramp Up Time 2 sec 2-60 sec
Sets the length of phase 22, which is the time allowed to let the fan accelerate up to speed before the
actuators start driving to prepurge position.
Max Time Low Fire 45 sec 0.2-600 sec
The allowable time to let the LMV3 drive to low fire before shutting the fuel valves after a call for heat has
been removed from input X5-03.1. In summary, this sets the maximum time for phase 62. This setting does
not affect fuel valve closing time in the event of a safety shutdown.
Min Time Home
Run
O 2 sec 2-60 sec
Sets the minimum time that the LMV3 will stay in phase 10 before proceeding to phase 12. The time does
not start until the actuators have finished moving (referencing and driving to home position).
