Note
No temperature monitoring with Temp-S
As a result of their non-linear characteristic, PTC temperature sensors are not suitable for
determining the instantaneous temperature.
Temp‑F
The Temp‑F temperature monitoring circuit comprises an individual temperature sensor.
Contrary to Temp‑S, this temperature sensor only monitors one phase winding. As a
consequence, Temp‑F is only used for monitoring the temperature and diagnosing the motor
winding temperature.
NOTICE
Motor destroyed as a result of overtemperature
If you use Temp‑F for thermal motor protection, then the motor is not adequately protected
against destruction as a result of overtemperature.
• Evaluate the Temp-S temperature monitoring circuit to implement thermal motor
