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
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.
