  • provide an example you can modify to develop your own configuration

  • serve as a starting point for the development of more complex configurations, incorporating such additional features as HMI or network control

Functions Performed

When the LTM R controller has been configured in order to help protect and control the motor and pump, it will perform the following functions:

  • thermal overload protection

  • motor temperature sensor protection

FLC (Full Load Current) Settings

FLC Basics

NOTE: Before setting the FLC, first set the Contactor rating and Load CT ratio.
  • Load CT ratio = Load CT primary / (Load CT secondary * Passes)

  • Current sensor max = Current range max * Load CT ratio

  • Current range max is determined by the LTM R controller commercial reference. It is stored in units of 0.1 A and has one of the following values: 8.0, 27.0, or 100.0 A

  • Contactor rating is stored in units of 0.1 A and is set by the user between 1.0 and 1000.0 A

  • FLCmax is defined as the lower of the Current sensor max and the Contactor rating values

  • FLCmin = Current sensor max / 20 (rounded to the nearest 0.01 A.). FLCmin is stored internally in units of 0.01 A

NOTE: Do not set the FLC below the FLCmin.

Conversion of Amperes to FLC Settings

FLC values are stored as a percentage of FLCmax

FLC (in %) = FLC (in A) / FLCmax

NOTE: FLC values must be expressed as a percentage of FLCmax (resolution of 1 %). If you enter an unauthorized value, the LTM R will round it up to the nearest authorized value. For example, on a 0.4-8 A unit, the step between FLCs is 0.08 A. If you try to set an FLC of 0.43 A, the LTM R will round it up to 0.4 A.

Example (No External CTs)

Data:

  • FLC (in A) = 9 A

  • Current range max = 27.0 A

  • Load CT primary = 1

  • Load CT secondary = 1

  • Passes = 1or 2

  • Contactor rating = 18.0 A

Calculated parameters with 1 pass:

  • Load CT ratio = Load CT primary / (Load CT secondary * passes) = 1 / (1 * 1) = 1.0

  • Current sensor max = Current range max * Load CT ratio = 27.0 * 1.0 = 27.0 A

  • FLCmax = min (Current sensor max, Contactor rating) = min (27.0, 18.0) = 18.0 A

  • FLCmin = Current sensor max / 20 = 27.0 / 20 = 1.35 A

  • FLC (in %) = FLC (in A) / FLCmax = 9.0 / 18.0 = 50 %

Calculated parameters with 2 passes:

  • Load CT ratio = 1 / (1 * 2) = 0.5

  • Current sensor max = 27.0 * 0.5 = 13.5 A

  • FLCmax = min (13.5, 18.0) = 13.5 A

  • FLCmin = Current sensor max / 20 = 13.5 / 20 = 0.67 A

  • FLC (in %) = FLC (in A) / FLCmax = 9.0 / 13.5 = 66 %
