A.2.7
Connecting the temperature sensor
Requirements
●
3RW50 soft starter with thermistor motor protection
●
Motor with temperature switch (e.g. Thermoclick) or thermistor (e.g. PTC type A)
Procedure
1.
Remove the copper link between terminals and T11 / T21 and T22.
2.
Connect the temperature sensor:
Temperature switch at terminals T21-T22
Thermistor at terminals T11-T12
Note
3RW50 soft starter with thermistor motor protection in hazardous areas
Note that the operation of a 3RW50 soft starter with thermistor motor protection in hazardous
areas is only possible with a thermistor (e.g. PTC Type A).
You will find additional information on the operation of motors in hazardous areas in
Chapters ATEX / IECEx-certified motor overload protection (Page 133) and Thermistor
motor protection with temperature sensor (optional) (Page 128).
Result
The 3RW50 soft starter monitors the motor for excessive temperature. The motor is shut
down if the maximum temperature limit is exceeded. The setting for RESET MODE
determines how the motor is restarted.
