Temperature sensor input
There are two ways of connecting a temperature sensor:
1. Via X133, terminals 7 and 8
2. Via X23, pins 1 and 8
However, only one temperature sensor may be connected as otherwise the parallel circuit
will be sensed and incorrect temperature values will be generated.
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.
WARNING
Danger to life due to electric shock in the event of voltage flashovers on the temperature
sensor cable
Voltage flashovers in the signal electronics can occur in motors without safe electrical
separation of the temperature sensors.
• Only use temperature sensors that fully comply with the specifications of the safety
isolation.
• If safe electrical separation cannot be guaranteed (for linear motors or third-party
motors, for example), use a Sensor Module External (SME120 or SME125) or Terminal
Module TM120.
