Quick Start Guide
FLC (Full Load Current) Settings
FLC Basics Load CT ratio = Load CT primary / (Load CT secondary * Passes)Current sensor max = Current range max * Load CT ratioCurrent range max is determined by the controller commercial reference number.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.
Conversion of Amperes to FLC Settings
FLC values are stored as a percentage of FLCmaxFLC (in %) = FLCA / FLCmax
Example (No External CTs)
Data:FLCA = 9 ACurrent range max = 27.0 ALoad CT primary = 1Load CT secondary = 1Passes = 1Contactor rating = 18.0 A
Calculated parameters with 1 pass:Load CT ratio = Load CT primary / (Load CT secondary * passes) = 1 / (1 * 1) = 1.0Current sensor max = Current range max * Load CT ratio = 27.0 * 1.0 = 27.0 AFLCmax = min (Current sensor max, Contactor rating) = min (27.0, 18.0) = 18.0 AFLCmin = Current sensor max / 20 = 27.0 / 20 = 1.35 AFLC = FLCA / FLCmax = 9.0 / 18.0 = 50%
Calculated parameters with 2 passes:Load CT ratio = 1 / (1 * 2) = 0.5Current sensor max = 27.0 * 0.5 = 13.5 AFLCmax = min (13.5, 18.0) = 13.5 AFLCmin = Current sensor max / 20 = 13.5 / 20 = 0.67 AFLC = FLCA / FLCmax = 9.0 / 13.5 = 66%
Note: Do not set the FLC below FLCmin.
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 0.4-8A unit, the step between FLCs is 0.08A. If you try to set an FLC of 0.43A, the LTM R will round it up to 0.4A.

Standard Requests on a PLC Platform
Example of a Read Operation (Modbus Request Code 3)
The example below describes a READ_VAR request, within a TSX Micro or Premium platform, in order to read the LTM R states at address 4 (slave n° 4) contained in internal word MW0:
Syntax with PL7 software:
1 Address of the device with which you wish to communicate: 3 (device address), 0 (channel), 4 (device address on the bus)
2 Type of PL7 objects to be read: MW (internal word) 3 Address of the first register to be read: 455 4 Number of consecutive registers to be read: 15 Word table containing the value of the objects read: MW0:16 Read report: MW100:4
Variant with Unity Pro software:
IF %M0 AND NOT %MW100.0 THEN READ_VAR(ADDR(‘0.3.0.4’),’%MW’,455,1,%MW100:4,%MW0:1);RESET(%M0);END_IF;

Example of a Write Operation (Modbus Request Code 16)
The example below describes a WRITE_VAR request, within a TSX Micro or Premium platform, in order to control an LTM R by sending the contents of internal word MW 502:
Syntax with PL7 software:
1 Address of the device with which you wish to communicate: 3 (device address), 0 (channel), 4 (device address on the bus)
2 Type of PL7 objects to be written: MW (internal word)3 Address of the first register to be written: 7044 Number of consecutive registers to be written: 15 Word table containing the value of the objects to be sent: MW502:16 Write report: MW200:4
Variant with Unity Pro software:
IF %M0 AND NOT %MW200.0 THEN WRITE_VAR(ADDR(‘0.3.0.4’),’%MW’,704,1,%MW502:1,%MW200:4);RESET(%M0);END_IF;
