Schneider Electric LTMR08DBD, part of the LTMR (TeSys T) sub-range, is a motor management controller designed for comprehensive motor and system protection. It supports various control modes including local operation via terminal block or HMI terminal, and remote operation through a network. The device offers multiple operating modes such as Overload, Independent, Reverser, 2-step, 2-speed, and Custom mode. Fault management capabilities include manual, automatic, and remote reset options, alongside extensive fault statistics like protection fault counters, protection alarm counters, diagnostic fault counters, motor control function counters, and a detailed fault history. Fault diagnostics cover internal watchdog faults, controller internal temperature, temperature sensor, current, and voltage connections, motor control commands, control configuration checksum, and loss of communication. Motor statistics provided include the number of motor control commands, operating time, number of starts per hour, last start I max, and duration of last start. Thermal overload statistics feature time to trip and time to restart, while system operating statistics monitor run, on, start, alarm, and fault statuses. The connection type is a 3 measurement current transformer control circuit with screw-clamp terminals, utilizing the DeviceNet communication protocol. It is a 3 Pole device with protection functions against thermal overload, motor temperature, phase imbalance, phase failure, phase reversal, long starting time, locked rotor, minimum and maximum current load limit variations, and earth fault. The rated current ranges from 0.4-8 A, with a maximum capacity of 800 A using current transformers. Protection settings include multiple classes for thermal overload, PTC binary and BTC/NTC analogue settings for motor temperature, and specific settings for phase imbalance, phase failure, phase reversal, long starting time, locked rotor, current load limit variations, and earth fault. The supply voltage is 24 V DC, with a phase-to-phase rated voltage for AC at 50-60Hz up to 690 V. Measurement functions encompass current/phase, earth current, average current, current imbalance between phases, thermal capacity level, and motor temperature rise.
