LMV
CurrMode 0/4mA (S) 0..20mA
0..20mA
4..20mA Selects the output signal of X63 to be either a 0-20mA signal or a 4-20mA signal. NOTE: This
has no effect when
OutValueSelection is set to "Load".
x x x
Scale20mA perc (S) 100% 0-999.9%
Scales the analog output for the percent values (other than Load). Specifically, this
parameter defines what percentage of Load 0, O2, Speed VSD, or Flame will output 20mA.
x x x
Scale20mA temp (S) 1562 F 32-3632 F
Scales the analog output for the temperature values. Specifically, this parameter defines
what temperature (read by Temp Pt1000,Temp Ni1000, etc.) will output 20mA.
x x x
Scale20mA press (S) 2 PSI 0-1449 PSI
Scales the analog output for the pressure value. Specifically, this parameter defines what
pressure (read by Press X61) will output 20mA.
x x x
Scale20mA angle (S) 90 deg 0-90 deg
Scales the analog output for the actuators. Specifically, this parameter defines what angular
degrees will output 20mA.
x x x
Scale 0/4mA (S) 0% 0-999.9%
Sets the start of the scale for every process value other than "Load". (The start of the scale
"Load 0" can be set here, but if "Load" is selected this parameter has no effect.) For example
: If parameter
OutValueSelection is set to "Pos Air", CurrMode 0/4mA is set to 4mA,
Scale20mA angle is set to 90 deg, and Scale 0/4mA is set to 0%, then 12 mA will be output
when the air actuator is at 45 degrees, and 20mA will be output at 90 degrees. If all other
values are unchanged and
Scale 0/4mA is now set to 50%, then 4 mA will be output when
the air actuator is 45 degrees, and 20mA will be output when the actuator is at 90 degrees.

StartAdaption (U)
This starts the adaption process. During the adaption process, the LMV5 will determine the
thermal response of the system (burner / boiler and attached thermal users). Values for PID
will be calculated based on this information. The LMV5 does this by modulating to minimum
load and letting the system "settle" to a particular pressure or temperature. After this
"settling" period, the LMV5 will modulate up to the
AdaptionLoad and see how long it takes
for the system temperature / pressure to respond.
Based off of this response, the LMV5 will choose values for P, I, and D. These calculated
values are implemented by choosing "Adaption" under
StandardParam .
NOTE: Adaption has to be started when the burner is running and a representative load
exists on the system.
x x x
AdaptionLoad (U) 100% 40-100%
This load is used to determine the thermal response of the system during adaption only.
LMV5 will travel to this load during the heating phase of the adaption.
