Displays the real time difference between the target speed (in %) and the actual speed (in %). Used to
observe the accuracy of the VSD speed control through the operating range.
Displays the real time speed of the VSD. Displayed in RPM.
Displays the real time speed of the VSD. Displayed as a percentage of the standardized speed.
This setting displays the active load source. There are five ways of sending a load command to the LMV3. If
multiple commands are received at the same time, the LMV3 uses the following priorities to determine
which command to follow:
1 = setting the fuel-air ratio curve (via parameter 400)
2 = manual mode (enabled during operation or via parameter 121)
3 = Modbus command on terminal X92
4 = 4-20 mA signal on terminal X64
5 = 3-position signal on terminals X5-03.2 and X5-03.3 (LMV37 only)
Parameter only exists on an LMV36: Displays the current fuel selected (0 or 1).
Displays the status of the inputs (index 00) and outputs (index 01) with a bit-coded total.
Contact feedback network counter register.
Displays the required state of the output relays with a bit-coded total.
Displays the real time mains voltage. For 120 VAC power, multiply the displayed value by 0.843. For 230
VAC power, multiple the displayed value by 1.683. Measured at terminal X3-04 pin 4 and pin 5.
Displays the raw flame signal from 0-100% for any flame scanner type. A flame failure occurs when the
flame signal drops below 24% for the time period specified by parameter 186 (fuel 0) or 187 (fuel 1). This
signal refers to input terminal X10-06 (UV scanners) or input terminal X10-05.2 (flame rods).
Displays the real time fuel flow.
Displays the real time phase of the LMV3.
Displays the real time fault code.
Displays the real time fault diagnostic.
Displays the total number of fault flags. This value can be reset by pressing the left or right arrow to change
the value to 00000000 and then pressing Enter.
