The Multifunction Control Unit

The LUCM Multifunction Control Unit controls, protects and monitors the LUBxx and

LUSxx bases (listed above) and performs the following functions:

Protection

 against overcurrent

 against thermal overloads, with choice of trip classes from 5 to 30

 against ground faults

 against phase imbalances

 against mechanical jams during or after the start-up phase

 against idling

 against tripping of the starter via an external signal (as an option)

Warning

The LUCM Multifunction Control Unit includes a warning associated with each of the

above listed protection functions. The warning level can be configured and is

independent from the protection trip level.

Diagnostic

Records and displays:

 number of operating hours for the motor

 number of starts

 number of trips

 cause of each trip

For the last five trips, the multifunction control unit records the status of the motor-

starter at the time of the trip (value of currents, thermal status, and trip type).

Preliminary Setup Requirements

Prior to using the Advantys STB Software (ACS) to configure the TeSys U Sc Mu L

on an STB island, you need to set the baud rate, node ID address and assemble the

starter-controller components (see page 178).
