Parameter Name
Modbus Address 1 1-247 Sets the LMV3 address for Modbus (job specific).
Baud Rate 1 0-1
Sets the baud rate of the Modbus port X92:
0 = 9600 bit/s
1 = 19200 bit/s
Parity 0 0-2
Sets the parity of the Modbus port X92:
0 = none
1 = odd
2 = even
Default Load Not set 0-100%
This sets the fire rate when Modbus communication is interrupted. A setting from 20-100% will set the
output of the burner. A setting of 0-19.9% will shut down the burner.
Total Faults Displays the total number of faults the LMV3 has received. Not resettable.
Operating Hours
Displays the total number of hours in operation. This value can be reset by pressing the left or right arrow
to change the value to 0 and then pressing Enter.
Powered Hours Displays the total number of hours the LMV3 has been powered. Not resettable.
Startups
Displays the total number of startups. This value can be reset by pressing the left or right arrow to change
the value to 0 and then pressing Enter.
Parameter only exists on an LMV36: Displays the total number of startups. Not resettable.
Displays the total number of startups on both fuels (LMV36), or total startups (LMV37). Not resettable.
Fuel Used
Displays the totalized volume of fuel. This value can be reset by pressing the left or right arrow to change
the value to 0 and then pressing Enter.
Total Revert
Parameter only exists on an LMV37: Displays the total number of times the burner has used the "revert to
pilot" function to switch back to running on the pilot only. Not resettable.
Flame Failure
Response Time (FFRT)
O
186:00 = 0
186:01 = 0
187:00 = 0
187.01 = 0
0-30
Sets the flame failure response time (FFRT). The LMV3 has a base flame failure response time of
approximately 1 second. This setting adds tenths of a second to the base time. For example, the maximum
setting of 30 adds 3 seconds to the 1 second base time for a total flame failure response time of 4 seconds.
Index 00 = Flame failure response time when using a QRB... flame scanner
Index 01 = Flame failure response time when using a QRA... flame scanner or a flame rod
Lockout Position S 0 0-1
This setting determines the position that the actuators and VSD will drive to when a lockout occurs:
0 = home position
1 = postpurge position
