Connector type: 25-pin SUB D connector
Measuring current via temperature sensor connection: 2 mA
Accuracy of the temperature measurement:
1)
- KTY: ±7 °C (including evaluation)
- Pt1000: ±5 °C (Pt1000 tolerance class B according to EN 60751 including evaluation)
- PTC: ±5 °C (including evaluation)
NOTICE
Damage to motor due to 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.
