Temperature sensors and electrical wiring
The temperature sensors can be evaluated, for example, as follows:
● Temperature sensor
– Motor 1: Connection via SME12x and evaluation via the drive control
– Motor n: not connected
(short-circuited and connected to the PE)
● Temperature switch
– Motor 1 to n: Evaluation via the drive control

WARNING
When connecting-up the temperature monitoring circuits, carefully observe the
requirements regarding protective separation in accordance with EN 61800-5-1.

2.13.4 Thermal motor protection
Temperature monitoring circuits Temp-F and Temp-S
The motors are supplied with two temperature monitoring circuits: Temp - F and Temp - S.
Temp-F is to monitor and evaluate the temperature characteristic in the motor being used.
Temp-S is used to activate motor protection if the motor windings get too hot.
Both circuits are independent of each other. They are generally evaluated via the drive
system. For temperature monitoring, the SME12x Sensor Modules can be used for thermal
motor protection.
Temp-F (KTY 84 Sensor)
The temperature monitoring circuit Temp-F consists of a KTY 84 temperature sensor located
at the coils. Under certain circumstances – especially when the individual phases have a
different current level – this can mean that the maximum temperature of the three phase
windings is not measured. An evaluation of Temp-F for motor protection is therefore not
permissible. Temp-F is used to monitor the temperature - and if necessary to output an
alarm indicating that the drive is being switched off because Temp-S has responded.
