175.2 Status PU temperature model
In this parameter the user can read out information regarding the status of the overload
monitoring of the device
Bits 4 and 5: Important, if the PU temperature model is activated >175.2< bit 0 = 1, only.
175.15 Power unit thermal load
This parameter displays the instantaneous thermal load of the device (ThL actual value),
which is evaluated from the PU overload monitoring via the temperature model.
The current is limited at 105% to the PU max. actual value of continuous current Z175.7–.
If PU overload monitoring via the temperature model is not active, this parameter isn't im-
portant (see status PU temperature model Z175.2–).
Bit Meaning
0 Display of the active PU overload monitoring model
0: Ixt model active
1: Temperature model active
1 Availability of the temperature model
(complete data set of the temperature model)
0: not available
1: available
2 Availability of the lxt model:
0: Ixt model may not be activated. The device may be operated with the
temperature model only.
1: Ixt model may be activated.
(only of importance if the data sets of the temperature model are available
>175.2< bit
1 = 1)
