2.42.2 Setting Hints
General
The temperature detection function is only effective and accessible if it has been as-
signed to an interface during the configuration of the protection functions (Section
2.2.1). Address
is used to allocate the thermobox(es) to the
interface (e.g. interface C) through which it will be operated. The number of detector
inputs and the communication mode are selected with address
. The temperature unit (°C or °F) has been set in Power System Data 1 at ad-
dress
Settings on the
Protection Device
The settings to be made on the protection device are the same for each input; they are
described here as an example for measuring input 1.
For RTD1 (temperature detector for measuring 1), the type of temperature detector is
set at address
. Setting options are
W and
W. Where no measuring point is provided for RTD1,
=
is set. This setting is only possible with DIGSI
®
4 under „Advanced Pa-
rameters“.
