Display of the load current used by the thermal overload protection function to
calculate the tripping time.

OL_DA: Object temp. THRM1
004 156
Not measured -40 300 °C Fig. 3-67, (p. 3-97)

Display of the temperature of the protected object as determined by function
THRM1 or THRM2, respectively.

Not measured -40 215 °C Fig. 3-67, (p. 3-97)
[spacer]
Display of the coolant temperature of the protected object. Depending on the
setting at THRM1: Select CTA PSx or THRM2: Select CTA PSx for
coolant temperature acquisition, one of the following values will be displayed:
●
Setting Default temp. value : Display of the set temperature value.
●
Setting From PT100: Display of the temperature measured by the
resistance thermometer.
●
Setting From 20 mA input: Display of the temperature measured via the
20 mA input.

Display of the time remaining before the thermal overload protection function
THRM1 or THRM2, respectively, will reach the tripping threshold.

OL_DA: Offset THRM1 replica

[spacer]
Display of the additional reserve if the coolant temperature is taken into
account. This display is relevant if the coolant temperature has been set to a
value below the maximum permissible coolant temperature or, in other words, if
the thermal model has been shifted downwards.
If, on the other hand, the coolant temperature and the maximum permissible
coolant temperature have been set to the same value, then the coolant
temperature is not taken into account and the characteristic is a function of the
current only. The additional reserve amounts to 0 in this case.
