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 0190 RTD-BOX INPUT 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 0191 RTD CONNEC-

TION. The temperature unit (°C or °F) has been set in Power System Data 1 at ad-

dress 0276 TEMP. UNIT.

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 9011A RTD 1 TYPE. Setting options are Pt 100 W, Ni 120 W and

Ni 100 W. Where no measuring point is provided for RTD1, RTD 1 TYPE = Not

connected is set. This setting is only possible with DIGSI
