Accuracy of the temperature measurement:
- KTY: ±7 °C (including evaluation)
- Pt1000: ±5 °C (Pt1000 tolerance class B according to EN 60751 including evaluation)
- PTC: ±5 °C (including evaluation)
Note
Permissible voltage values
The common mode range must not be violated in order to avoid incorrect analog-digital
conversion results. The following voltages are permissible:
● Input voltage: ±30 V (destruction limit)
● Common mode voltage: ±10 V with respect to ground potential (increased errors when
exceeded)
NOTICE
Damage to motor in the event of incorrectly connected KTY temperature sensor
If a KTY temperature sensor is connected with incorrect polarity, it is not possible to detect
when the motor overheats. Overheating can cause damage to the motor.
● Connect a KTY temperature sensor with the correct polarity.
Note
In order to minimize noise emission, shielded cables should be used.
Note
The maximum cable length for a shielded cable applied on both sides to the temperature sensor
and to the analog inputs is 30 m.
