The temperature reference setting. The manufacturer's temperature
presumptions apply and the thermal correction factor is 1.00 (rated
temperature). For underground cables the set value for this is usually 15
̊

and for cables in the air it is usually 25
̊
C.

The selection of whether or not the curve temperature/coefficient pair is in use.
The minimum number to be set for the temperature/coefficient curve is two
pairs and the maximum is ten pairs. If the measured temperature is below
the set minimum temperature reference or above the maximum set
temperature reference, the used temperature coefficient is the first or last
value in the set curve. This setting is visible if "Ambient lin. or curve" is set to
"Set curve".
Operating characteristics
The operating characteristics of the machine thermal overload protection function are completely
controlled by the thermal image. The thermal capacity value calculated from the thermal image can set
the I/O controls with ALARM 1, ALARM 2, INHIBIT and TRIP signals.
