Configuring (Parameterization of) an LMV5 with a Default Parameter Set
The procedure below assumes an LMV5 with a default parameter set. If the LMV5 is mounted to a
burner / boiler, the OEM(s) may have already changed the parameters from the default setting and
parameterized the LMV5 for the application.
Section 3 (Parameters) gives a detailed explanation of all of the parameters in the LMV5, as well as
highlights which parameters must be set (marked with a double asterisk **) and which parameters are
frequently used (shaded).
This procedure gives a general guideline of what parameters need to be set to get an LMV5 running on a
typical burner/ boiler. Every burner is different, so it is likely that every burner will need a somewhat
unique parameter set to run correctly.
When an LMV5 with a default parameter set is powered up and wired correctly, it will go into alarm and
state that "no fuel train is defined". During the parameterization, the alarm does not need to be reset.
Moreover, the alarm will come back immediately until at least a few key parameters are set. The
recommendation is to silence the alarm horn, and leave the LMV5 in a state of alarm until the key
parameters are set.
1. Log in at the OEM password level. From the factory, the OEM password for the LMV5 is
"START".
2. Set the Burner ID. This can be found in the main menu under Updating. The OEM password will
be required when the Updating menu is entered. The Burner ID is a unique number which
matches the burner to the parameter set in the LMV5. Typically, the serial number of the
burner is used as the Burner ID.
3. Configure the load controller sensor (except LMV51.0...) using the following menu path:
Params & Display > LoadController > Configuration
The default configuration is for a hot water boiler (temperature control) with a PT100 RTD
temperature sensor. For a steam boiler (pressure control), set the following parameters to the
following settings:
Sensor Select = PressSensor
Ext Inp X61 U/I = 0..10V or 4..20mA (sensor dependent)
MRangePressSens = High range of pressure sensor
4. Set the fuel train(s). If only gas is to be fired, only a gas fuel train must be selected. If only oil is
to be fired, only an oil fuel train must be selected. For dual fuel burners, both a gas and oil fuel
train must be selected. Fuel trains can be set using the following menu path:
Params & Display > BurnerControl > Configuration > ConfigGeneral
See the following pages for fuel train information. "Pilot Gp2" is typical for gas piloted gas
burners and "LO w Gasp" is typical for gas piloted oil burners.
