/ bimetallic switch with NC contact
With the 20 kW and 40 kW Basic Line Modules, the
temperature sensor of the braking resistor (bimetallic
switch with NC contact) is connected to the tempera-
ture input.
of the temperature input:
Temperature at the braking resistor in the operating
range → resistance value ≤ 100 ohms
Overtemperature at the braking resistor → resistance
value > 100 ohms
Fault responses: An alarm is output and the Basic Line
Module is deactivated with a fault after one minute, if
overtemperature is still present at the braking resistor.
If there is no braking resistor, terminals 1 and 2 must
be jumpered to deactivate the overtemperature.

The temperature sensor type and the temperature output can be selected by parameter (see the SINAMICS S120/S150
List Manual).
