Application-specific parameter sets that can be loaded on-site (depending on
the control panel).
Notes on the designations A1 and B
A1 parameter sets should be operated at a room temperature of around 25 °C.
However, they can be applied at temperatures up to 50 °C. The static response
temperature is 60 °C.
B parameter sets are normally operated at around 40 °C. They can however be
used at up to 65 °C. The static response temperature is 80° C.
Notes on the designations R and S
Compared with S parameter sets, R parameter sets also trigger an alarm when the
temperature increases (e.g. from 20 °C to 50 °C within a few minutes).
