Approvals

1) Case by case

Digital

  • Illuminated LCD with 2 lines of 16 characters each
  • Selectable languages: English, German, French or Spanish (aditional on request)
  • The LCD indicates the motor current, fault descriptions and statistical data.
  • The LEDs provide a quick status indication. (control voltage on, motor start, motor on, motor stop, fault)
  • Easy settings by six clearly marked keys, user-friendly software with factory default parameters.

Communication RS 485

Modbus Profibus

RS 485 with MODBUS or PROFIBUS protocol enable:

  • Remote (start, stop, etc.)
  • Monitoring (motor current, faults, statistical data)
  • Remote parameter setting
  • Remote reset

Bypass

Internal bypass

  • This reliable components bypass autotransformer after the motor is at speed.
  • In addition the starters provide an auxiliary contact, allowing signaling of a successful motor start.
    Attention! Many of our competitors call these auxiliary relays “a bypass contact”!
  • The bypass function reduces the heat dissipation and eliminates the EMC load of the system.
