(1) For the permissible values for the main and control voltage (dependent on the MLFB),
refer to chapter Technical data (Page 127) .
WARNING
(2) Automatic restart.
Can result in death, serious injury, or property damage.
The start command (e.g. issued by the PLC or switch S1) must be reset prior to issuing a
RESET command because the motor attempts to restart again automatically following this
RESET command (3TK or 3RW) if a start command is still present. This particularly applies
if the motor protection has tripped. For safety reasons, you are advised to integrate the
group fault output (terminals 95 and 96) in the controller.
(3) Alternatively, the motor feeder can be assembled as a fuseless or fused version with type
of coordination 1 or 2. For the assignment of fuses and switching devices, refer to chapter
Technical data (Page 127)
For the optio
nal thermistor motor protection evaluation, refer to Typical
circuit for the optional
thermi
stor motor protection eval
uation (Page 175).
NOTICE
If the soft stop function is set (ramp-down time potentiometer set to >0 s) and the
emergency stop circuit is tripped, a "Missing load voltage, phase failure / missing load" fault
may be indicated on the soft starter. In this case, the soft starter must be reset according to
the selected RESET MODE.
