Description.(continued)
TeSys U starter control application
Presentation of the TeSys U starter-controller (1)
The TeSys U starter-controller is a direct motor starter that performs the
following functions:
Protection and control of single-phase or three-phase motors:
Disconnects power
Protects against overcurrent and short circuits
Protects against thermal overload
Performs power switching
Application control:
Provides protection alarms and application monitoring: duration of use, number
of faults, motor current values, etc.
Provides a logging function
Structure of a TeSys U starter with an STBEPI2145K module (1)
The starter-controller functions are implemented with a click-lock adjustment, thus
eliminating wiring:
On a power base 2 (LU2B + LU9BN11)
Of a 24 V control unit 3 (LUCB/D/C/M BL) for 0.09 to 15 kW motors
Of a parallel communication module (LUFC00) 4
Of options (additional contacts, reverser blocks) 5, including LU9M1
Combined with a TeSys U starter, each of the 4 channels of the STBEPI2145K
application-specic module features:
2 outputs:
Starter control
Reversal control
3 inputs:
State of circuit breaker (position of lever)
Presence of fault (short circuit, thermal)
State of main contactor (closed/open)
