Figure 3.3 Connection of the temperature sensor
For thermal monitoring of the motor winding, the temperature sensors
specified in Table 3.1 can be connected to terminals X3 /
ϑ
- and
ϑ
+.
Attention: Contrary to DIN VDE 0660-303 (short circuit dedection
< 20
Ω
) the CDD3000-HF will note a short circuit at < 50
Ω
.
For commissioning the correct type of temperature sensor used in the
connected motor must be set up. This measure is not necessary if a
matching motor data set is available.
