someone here is an expert in TESYS T in motor configuration with somove?
i have one LTMR08MFM with LTMEV40FM 0,4-8A and 3 transformers 200/1
and 1 pass in overload 3-wire mode.
My motor is 90KW/175A with out temistors or ground defect.
i configure the current and power of motor to LTMR08MFM and test the reset button but the default configuration back to 7,5 Kw/8,75A and the terminals 95/96 not open 
what I'm doing wrong ?
i am 'm new in Tesys T 
someone explain to me the configuration for 90Kw and the FLCmax adequate for stop motor over 175A in 15 seg.
many tkanks in advance. |

no one helped, i did some tests
to do a reset to device Tesys T just a short press the button reset (95 and 96 open in alarm and close in normaly operation)
if the touch is over until the red led start blinking, the parameters
go to default values.
continuing to press the reset button after the red LED flashing
the device turned off and you need restart the power energy.
nowhere pdf of scheneider teaches this, i think.
the FLC% is automatic with the corrent max of contactor and nominal corrent of motor
the help of schneider is this, i do not understand:
| Code: |
FLC (Full Load Current) Settings
FLC Basics
NOTE: Before setting the FLC, you must 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 %
