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
̊
C 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".
Operation 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.
