The type of tripping characteristic is dependent on the configured measuring module.
If a 3UF711*-1AA00-0 1st generation current / voltage measuring module is configured in a
parameter assignment, although a 3UF711*-1AA01-0 2nd generation current / voltage
measuring module is used, then the tripping characteristic remains that of the 1st
generation current / voltage measuring module.
If only the hardware of the measuring module is replaced, this does not result in any
change to the tripping behavior.
14.1.3.3 SIMOCODE pro with thermistor input
On 3UF70, you can use temperature sensor type A with a characteristic according to
IEC 60947-8 (DIN VDE 0660, part 303), DIN 44081 and DIN 44082.
Depending on the number of sensors, the following tripping and restart temperatures apply.
