Overview
2.1 Introduction
M101-M/M102-M is a motor protection and control device with a fieldbus interface.
M101-M/M102-M is a microprocessor-based device. All motor protection and control functions are implemented with the microprocessor, as well as interlocking functions, the calculation of operating, diagnosis and statistical data and communication.
Standard features simplify maintenance and plant expansion. One M101-M/M102-M is required for every starter unit in the MCC.
Motor protection is included for the most common causes of failure to prevent costly shutdowns and rewinds. These include overload, stalled rotor, ground fault and phase failure etc.
M101-M/M102-M with its redundant RS485 interface makes it possible to network upward with automation level in a high speed and reliable way. Any M101-M/M102-M may be interrogated on demand to determine both actual and operating parameters. Fast response time for alarm or trip status makes real time control of a complete process possible. Statistical recording of running hours and
number of operations assists with predictive maintenance scheduling.

4.1.7 Current measurement terminal
M101-M/M102-M measures continuously three motor phase currents. The phase current data will be used by the protection functions and is reported to the fieldbus. Phase currents are reported as relative value. Relative value is proportional to the motor nominal current In.
Current wires are lead through current sensors from either side of the terminal.
Direction can be either L->T or T->L considering that all currents must have the same direction.
Motor nominal currents above 63A are not measured directly, but instead intermediate current transformer’s secondary side is connected through M101-M/M102-M current measurement terminal. Note: when one phase system is selected, current is measured only from phase A.
4.1.8 Contactor control output
M101-M/M102-M supports several motor starter types. The control of the contactor is performed with internal relays (Output CCA, CCB, CCC) by the microprocessor.
Internal relays CCA and CCB are hardwire-interlocked to prevent both contactors being closed at the same time.
Note: M101-M has the relays CCA and CCB only.
